  1. Fulltext Population & social indicators of food and nutrition in Peninsular Malaysia
    Chong YH
    Med J Malaysia, 1982 Jun;37(2):134-40.
    PMID: 6813659
    Health, including nuirition is not independent but is closely associated with the social and economic environment. Malnutrition itself can cause death, but more commonly, it can cause considerable ill-health, physical retardation, impaired mental performance, loss in productivity and a decline in the quality of life. The effects of malnutrition as obstacles to socio-economic development are now well recognised. In a rapidly developing country like Malaysia, the nutritional and nutritionally-related problems present themselves with contrasting features. While population indicators such as toddler mortality, incidence of low birthweight and food balance sheet studies suggest an improving nutritional situation, methods of direct assessment have shown that chronic protein-energy malnutrition and anaemia are sWI common amongst pre-school children in both the rural and urban disadvantaged sectors. Moderate anaemia also affects a significant proportion of older children and women of childbearing age. Intestinal parasites, another indicator of under development at the local level, are ubiquitous in the rural setting and urban slums owing to unsatisfactory waste disposal. In striking contrast, diseases associated with dietary excesses and increasing affluence have now emerged as the major killers. This changing pattern of mortality and morbidity along the lines encountered by the industrialised societies is now dramatised by the fact that road accidents are now claiming a large number of victims. It is clear that while continued efforts should be given to the improvement of the nutritional health of both rural and urban poverty communities, little time should be wasted in considering the adoption of public health measures aimed at stemming the rising number of deaths associated with our increasing affluence, particularly those diseases that are nutritionally linked, such as coronary heart disease, hypertension and diabetes mellitus, not forgetting the increasing road toll afflicted by the motor vehicle.

    PMID: 33804160 DOI: 10.3390/nu13030945
    Living free from hunger is a basic human right. However, some communities still experience household food insecurity. This systematic literature review explored different aspects of household food insecurity in Malaysia including vulnerable groups, prevalence, risk factors, coping strategies, and the consequences of food insecurity. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Thirty-three relevant articles were selected from scientific databases such as CINAHL, Pubmed and Google Scholar, scrutiny of reference lists, and personal communication with experts in the field. The prevalence of household food insecurity in Malaysia was unexpectedly reported as high, with affected groups including Orang Asli, low-income household/welfare-recipient households, university students, and the elderly. Demographic risk factors and socioeconomic characteristics included larger household, living in poverty, and low education. Coping strategies were practices to increase the accessibility of food in their households. Consequences of household food insecurity included psychological, dietary (macro- and micronutrient intakes), nutritional status, and health impacts. In conclusion, this review confirmed that household food insecurity in Malaysia continues to exist. Nevertheless, extensive and active investigations are encouraged to obtain a more holistic and comprehensive picture pertaining to household food security in Malaysia.

  3. Food consumption patterns and nutrition transition in South-East Asia
    Lipoeto NI, Geok Lin K, Angeles-Agdeppa I
    Public Health Nutr, 2013 Sep;16(9):1637-43.
    PMID: 23157893 DOI: 10.1017/S1368980012004569
    OBJECTIVE: The present study was done to confirm the relationship between changes in food patterns and nutrition transition in three South-East Asian countries, namely the Philippines, Malaysia and Indonesia.

    DESIGN: This was a cross-sectional study conducted between August 2008 and August 2009 using three methods: interviews, focus group discussions and analyses of government reports.

    SETTING: The study was conducted in rural and urban areas in Manila and Calabanga (Philippines), Selangor and Kuala Selangor (Malaysia), and Padang, Pariaman Tanah Datar and Limapuluh Kota (West Sumatra, Indonesia).

    SUBJECTS: Adults aged 18 to 77 years.

    RESULTS: The results showed that Filipinos, Malaysians and Indonesians have retained many aspects of their traditional diets. In fact, most participants in the study considered Western-style and franchise fast foods as snack or recreational foods to be consumed once in a while only. However, a significant difference was noted between urban and rural areas in food varieties consumed. Participants in urban areas consumed more varieties of traditional foods owing to their availability and the participants’ food purchasing power. Although traditional food patterns were maintained by most of the participants, more sugar and vegetable oils were consumed and added to the traditional recipes.

    CONCLUSIONS: The rapid nutrition transition in this region may be due, instead, to increasing food availability and food purchasing power, rather than to a shift in food preferences towards modern Western foods.

  4. Evaluating household food insecurity: applications and insights from rural Malaysia
    Cooper EE
    Ecol Food Nutr, 2013;52(4):294-316.
    PMID: 23802913 DOI: 10.1080/03670244.2012.707419
    Hunger is complex, encompassing experiences ranging from a family's forced acceptance of a monotonous diet to individual physiological pain. I evaluate the Household Food Insecurity Access Scale (HFIAS) as a means of capturing the universal elements of hunger without doing violence to its culturally-specific expressions within two Malay communities. The HFIAS is assessed conceptually by comparing its assumptions and concept-to-measurement gap with competing indicators and practically with respect to village conditions and practices. This case study recommends the HFIAS for this site and for communities that similarly lack maternal buffering, while highlighting the unique features of the local hunger experience.

  5. A lab-on-a-chip-based multiplex platform to detect potential fraud of introducing pig, dog, cat, rat and monkey meat into the food chain
    Razzak MA, Hamid SB, Ali ME
    Food Addit Contam Part A Chem Anal Control Expo Risk Assess, 2015;32(11):1902-13.
    PMID: 26437367 DOI: 10.1080/19440049.2015.1087060
    Food forgery has posed considerable risk to public health, religious rituals, personal budget and wildlife. Pig, dog, cat, rat and monkey meat are restricted in most religions, but their sporadic adulteration are rampant. Market controllers need a low-cost but reliable technique to track and trace suspected species in the food chain. Considering the need, here we documented a lab-on-a-chip-based multiplex polymerase chain reaction (PCR) assay for the authentication of five non-halal meat species in foods. Using species-specific primers, 172, 163, 141, 129 and 108-bp sites of mitochondrial ND5, ATPase 6 and cytochrome b genes were amplified to detect cat, dog, pig, monkey and rat species under complex matrices. Species-specificity was authenticated against 20 different species with the potential to be used in food. The targets were stable under extreme sterilisation (121°C at 45 psi for 2.5 h) which severely degrades DNA. The assay was optimised under the backgrounds of various commercial meat products and validated for the analysis of meatballs, burgers and frankfurters, which are popular fast food items across the globe. The assay was tested to detect 0.1% suspected meats under commercial backgrounds of marketed foods. Instead of simplex PCR which detects only one species at a time, such a multiplex platform can reduce cost by at least fivefolds by detecting five different species in a single assay platform.

  6. Aquatic foods to nourish nations
    Golden CD, Koehn JZ, Shepon A, Passarelli S, Free CM, Viana DF, et al.
    Nature, 2021 Oct;598(7880):315-320.
    PMID: 34526720 DOI: 10.1038/s41586-021-03917-1
    Despite contributing to healthy diets for billions of people, aquatic foods are often undervalued as a nutritional solution because their diversity is often reduced to the protein and energy value of a single food type ('seafood' or 'fish')1-4. Here we create a cohesive model that unites terrestrial foods with nearly 3,000 taxa of aquatic foods to understand the future impact of aquatic foods on human nutrition. We project two plausible futures to 2030: a baseline scenario with moderate growth in aquatic animal-source food (AASF) production, and a high-production scenario with a 15-million-tonne increased supply of AASFs over the business-as-usual scenario in 2030, driven largely by investment and innovation in aquaculture production. By comparing changes in AASF consumption between the scenarios, we elucidate geographic and demographic vulnerabilities and estimate health impacts from diet-related causes. Globally, we find that a high-production scenario will decrease AASF prices by 26% and increase their consumption, thereby reducing the consumption of red and processed meats that can lead to diet-related non-communicable diseases5,6 while also preventing approximately 166 million cases of inadequate micronutrient intake. This finding provides a broad evidentiary basis for policy makers and development stakeholders to capitalize on the potential of aquatic foods to reduce food and nutrition insecurity and tackle malnutrition in all its forms.

  7. Fulltext Muscle Fatty Acid Content in Selected Freshwater Fish from Bukit Merah Reservoir, Perak, Malaysia
    Jaya-Ram A, Fuad F, Zakeyuddin MS, Sah ASRM
    Trop Life Sci Res, 2018 Jul;29(2):103-117.
    PMID: 30112144 MyJurnal DOI: 10.21315/tlsr2018.29.2.8
    One of the oldest reservoirs in Peninsular Malaysia, Bukit Merah Reservoir, is a place in which locals participate in fishing activities. Inland fisheries are important to individuals, society and the environment; whereby they generate a source of income and food security. It is essential to gauge the nutrition value of fish caught in this location as food source, especially in terms of fatty acid composition, to better demonstrate its potential towards the betterment of human health and general well-being. From an initial list of 47 fish species available in Bukit Merah Reservoir, a total of seven edible freshwater fish species were identified, namely tinfoil barb (Barbonymus schwanenfeldii), Javanese barb (Barbonymus gonionotus), hampala barb (Hampala macrolepidota), beardless barb (Cyclocheilichthys apogon), glassfish (Oxygaster anomalura), striped snakehead (Channa striata) and horseface loach (Acantopsis dialuzona), and muscle fatty acid content was analysed to determine their nutritional value. Muscle of cyprinid fish contained substantial amount of omega-3 long-chain polyunsaturated fatty acids (LC-PUFA) compared to fish from Channidae and Cobitidae families. Javanese and tinfoil barbs muscle recorded the highest levels of combined eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) indicating the highest nutritional value comparatively. Unexpectedly, the striped snakehead, a predatory carnivore, contained lower levels of LC-PUFA compared to detrivorous/herbivorous fishes. This further justifies that the omega-3 polyunsaturated fatty acids (PUFA) content in fish muscle varies according to their feeding habits. Even though it has been recommended that marine fish be consumed to improve health to a certain extent, there still are benefits of consuming freshwater fish, as there are several species which contain considerable amounts of beneficial omega-3 PUFA.

  8. Fulltext Supplementary feeding increases nestling feather corticosterone early in the breeding season in house sparrows
    Salleh Hudin N, De Neve L, Strubbe D, Fairhurst GD, Vangestel C, Peach WJ, et al.
    Ecol Evol, 2017 08;7(16):6163-6171.
    PMID: 28861222 DOI: 10.1002/ece3.3114
    Several studies on birds have proposed that a lack of invertebrate prey in urbanized areas could be the main cause for generally lower levels of breeding success compared to rural habitats. Previous work on house sparrows Passer domesticus found that supplemental feeding in urbanized areas increased breeding success but did not contribute to population growth. Here, we hypothesize that supplementary feeding allows house sparrows to achieve higher breeding success but at the cost of lower nestling quality. As abundant food supplies may permit both high- and low-quality nestlings to survive, we also predict that within-brood variation in proxies of nestling quality would be larger for supplemental food broods than for unfed broods. As proxies of nestling quality, we considered feather corticosterone (CORT f), body condition (scaled mass index, SMI), and tarsus-based fluctuating asymmetry (FA). Our hypothesis was only partially supported as we did not find an overall effect of food supplementation on FA or SMI. Rather, food supplementation affected nestling phenotype only early in the breeding season in terms of elevated CORT f levels and a tendency for more variable within-brood CORT f and FA. Early food supplemented nests therefore seemed to include at least some nestlings that faced increased stressors during development, possibly due to harsher environmental (e.g., related to food and temperature) conditions early in the breeding season that would increase sibling competition, especially in larger broods. The fact that CORT f was positively, rather than inversely, related to nestling SMI further suggests that factors influencing CORT f and SMI are likely operating over different periods or, alternatively, that nestlings in good nutritional condition also invest in high-quality feathers.

  9. Nutritional composition and lipid oxidation stability of beef patties packed with biodegradable and non-biodegradable materials
    Lim S, Wan Rosli W
    Sains Malaysiana, 2014;43:1197-1203.
    Long term environmental problems of non-biodegradable plastic, the need to conserve finite fossil fuels and the impact of globalization of food supply are some of the driving forces in looking towards biodegradable plastics as an alternative to the existing petrochemical-based polymers for food packaging application. The stability of nutritional composition, lipid oxidation, physical traits of beef patties packed with different types of plastics and the surface morphology of plastics after 3 months of frozen storage (-18 were studied. Beef patties were packed with either non-biodegradable high density polyethylene (PE), hydro-biodegradable low density polyethylene/ thermoplastic sago starch plastic (PEs), hydro-biodegradable polylactic acid plastic (PIA) or oxo-biodegradable plastic (oxo)). There were no differences in most of the nutrients analyzed and lipid oxidation values of beef patties packed with either biodegradable or non-biodegradable plastics after storage. There were significant (p decreased in fat for cooked patties and moisture for both raw and cooked patties. Lipid oxidation indices of beef patties increased after storage but they were not significant (p Beef patties packed with biodegradable packaging materials were able to retain moisture without jeopardizing the diameter reduction during storage. In summary, the application of biodegradable plastics for packing beef patties was considered acceptable and can be suggested as an alternative packaging item to replace conventional polyethylene plastic packaging.

  10. Survey-based data on food security, nutrition and agricultural production shocks among rural farming households in northern Uganda
    Mwungu CM, Shikuku KM, Atibo C, Mwongera C
    Data Brief, 2019 Apr;23:103818.
    PMID: 31372462 DOI: 10.1016/j.dib.2019.103818
    Climate change, degradation of natural resources, conflict or civil war, diseases and poverty are among the key threats that impact agriculture, human nutrition, food security and food safety among rural households in developing countries. Sustainability of food systems and livelihoods will thus crucially depend on not only the ability to accommodate or recover from these threats but also to tap into opportunities for strengthening long-term capabilities. One approach to enhancing resilience to enhance food security and nutrition is building an evidence base to better understand the various types of smallholders, threats to agriculture production and the associated risks to food security and nutrition and household food preferences. Unfortunately, such data in many African countries is still unavailable or has not been shared publicly. In this paper, we describe data that were collected in Nwoya district, Northern Uganda in December 2017. These data can be used to assess the relationship between resilience of farm households to climatic risks and their food and nutrition security.

  11. Fulltext Pulse Crop Genetics for a Sustainable Future: Where We Are Now and Where We Should Be Heading
    Sahruzaini NA, Rejab NA, Harikrishna JA, Khairul Ikram NK, Ismail I, Kugan HM, et al.
    Front Plant Sci, 2020;11:531.
    PMID: 32431724 DOI: 10.3389/fpls.2020.00531
    The last decade has witnessed dramatic changes in global food consumption patterns mainly because of population growth and economic development. Food substitutions for healthier eating, such as swapping regular servings of meat for protein-rich crops, is an emerging diet trend that may shape the future of food systems and the environment worldwide. To meet the erratic consumer demand in a rapidly changing world where resources become increasingly scarce due largely to anthropogenic activity, the need to develop crops that benefit both human health and the environment has become urgent. Legumes are often considered to be affordable plant-based sources of dietary proteins. Growing legumes provides significant benefits to cropping systems and the environment because of their natural ability to perform symbiotic nitrogen fixation, which enhances both soil fertility and water-use efficiency. In recent years, the focus in legume research has seen a transition from merely improving economically important species such as soybeans to increasingly turning attention to some promising underutilized species whose genetic resources hold the potential to address global challenges such as food security and climate change. Pulse crops have gained in popularity as an affordable source of food or feed; in fact, the United Nations designated 2016 as the International Year of Pulses, proclaiming their critical role in enhancing global food security. Given that many studies have been conducted on numerous underutilized pulse crops across the world, we provide a systematic review of the related literature to identify gaps and opportunities in pulse crop genetics research. We then discuss plausible strategies for developing and using pulse crops to strengthen food and nutrition security in the face of climate and anthropogenic changes.

  12. Fulltext Understanding Host-Pathogen Interactions in Brassica napus in the Omics Era
    Neik TX, Amas J, Barbetti M, Edwards D, Batley J
    Plants (Basel), 2020 Oct 10;9(10).
    PMID: 33050509 DOI: 10.3390/plants9101336
    Brassica napus (canola/oilseed rape/rapeseed) is an economically important crop, mostly found in temperate and sub-tropical regions, that is cultivated widely for its edible oil. Major diseases of Brassica crops such as Blackleg, Clubroot, Sclerotinia Stem Rot, Downy Mildew, Alternaria Leaf Spot and White Rust have caused significant yield and economic losses in rapeseed-producing countries worldwide, exacerbated by global climate change, and, if not remedied effectively, will threaten global food security. To gain further insights into the host-pathogen interactions in relation to Brassica diseases, it is critical that we review current knowledge in this area and discuss how omics technologies can offer promising results and help to push boundaries in our understanding of the resistance mechanisms. Omics technologies, such as genomics, proteomics, transcriptomics and metabolomics approaches, allow us to understand the host and pathogen, as well as the interaction between the two species at a deeper level. With these integrated data in multi-omics and systems biology, we are able to breed high-quality disease-resistant Brassica crops in a more holistic, targeted and accurate way.

  15. Fulltext Using Population and Comparative Genomics to Understand the Genetic Basis of Effector-Driven Fungal Pathogen Evolution
    Plissonneau C, Benevenuto J, Mohd-Assaad N, Fouché S, Hartmann FE, Croll D
    Front Plant Sci, 2017;8:119.
    PMID: 28217138 DOI: 10.3389/fpls.2017.00119
    Epidemics caused by fungal plant pathogens pose a major threat to agro-ecosystems and impact global food security. High-throughput sequencing enabled major advances in understanding how pathogens cause disease on crops. Hundreds of fungal genomes are now available and analyzing these genomes highlighted the key role of effector genes in disease. Effectors are small secreted proteins that enhance infection by manipulating host metabolism. Fungal genomes carry 100s of putative effector genes, but the lack of homology among effector genes, even for closely related species, challenges evolutionary and functional analyses. Furthermore, effector genes are often found in rapidly evolving chromosome compartments which are difficult to assemble. We review how population and comparative genomics toolsets can be combined to address these challenges. We highlight studies that associated genome-scale polymorphisms with pathogen lifestyles and adaptation to different environments. We show how genome-wide association studies can be used to identify effectors and other pathogenicity-related genes underlying rapid adaptation. We also discuss how the compartmentalization of fungal genomes into core and accessory regions shapes the evolution of effector genes. We argue that an understanding of genome evolution provides important insight into the trajectory of host-pathogen co-evolution.

  16. Form and habit in species of malleus (including the "hammer oysters") with comparative observations on Isognomon isognomon
    Yonge CM
    Biol. Bull., 1968 Oct;135(2):378-405.
    PMID: 28368764 DOI: 10.2307/1539789
    1. Study of the structure and mode of life of Malleus regula provides the basis for consideration of the "hammer" species, M. malleus and M. albus.
    2. M. regula occurs byssally attached, vertically disposed on rocky substrates associated with mud and is widely distributed in the tropical Indo-Pacific.
    3. The distal two-thirds of the elongated shell is exclusively prismatic. By means of special pallial retractors the mantle lobes can be withdrawn within the nacreous region.
    4. The massive opisthodetic ligament has a short secondary extension of fusion layer.
    5. A promyal chamber on the right side proximal to the adductor increases water flow into the exhalant chamber.
    6. The long filibranch ctenidia provide a vertically extended food-collecting surface.
    7. The foot is concerned with planting of the massive byssus which emerges through a notch in the right valve but on the under ( i.e., dorsal) surface. There is also a unique and very long accessory foot, ventrally grooved, everywhere ciliated and in constant writhing activity due to blood pressure and intrinsic muscle. Moving freely throughout the lower mantle cavity it can only be concerned with cleansing.
    8. Pseudofaeces are ejected from the distal tip of the mantle cavity.
    9. M. malleus, the black hammer shell, occurs vertically embedded in coarse sand or sandy gravel. Byssus threads are attached to fragments within the substrate. The great anterior and posterior elongations of the hinge line (also exclusively prismatic) are separated by the byssal notch (now affecting both valves).
    10. Shells are usually excessively irregular due to the great exposure to damage and the almost unlimited powers of rapid repair by the three pallial extensions.
    11. M. albus, the white hammer shell, is stouter and inhabits muddy sand. During growth it loses the byssus with reduction of the foot and byssal retractors and closure of the byssal notch. The accessory foot is not affected. The animal becomes anchored in the substrate exclusively by the anterior and posterior extensions of the shell.
    12. Description of the typically rounded Isognomon ephippium leads to that of the elongated I. isognomon which occupies precisely the same habitat as M. regula.
    13. It lacks the pallial retractors, promyal chamber and accessory foot of Malleus, the nacreous region is more extended distally and the ligament is multivincular (the formation of which is discussed), producing some posterior, but never any anterior, extension of the hinge line.
    14. A remarkably dense mixed bed of M. regula and I. isognomon in Darvel Bay, Sabah (Borneo), is described. Different spawning periods, by preventing competition during settlement, may account for this complete intermixing of sympatric species, which, however, are generalized herbivores where numbers are not limited by food supply.
    15. From a basic epifaunal habit (Pteria, Isognomon, M. regula), members of the Pteriacea have become adapted for infaunal life within sponges (Vulsella, Crenatula) or within soft substrates ( M. malleus, M. alba and the Pinnidae).
    16. There is final discussion about elongation in monomyarians, i.e., in the genus Malleus and in I. isognomon.

  17. Fulltext Food production from animals in Asia: priority for expanding the development frontiers
    Devendra, C.
    ASM Science Journal, 2010;4(2):173-184.
    MyJurnal
    In agricultural systems, animals play a very important multifunctional role for developing communities
    throughout the world. This is reflected in the generation of value-added products like meat, milk and eggs for food security; socio-economic benefits like increased income, security and survival, and an infinite variety of services such as the supply of draught power and dung for soil fertility. However, and despite this importance, the situation is awesome since the projected total meat and milk consumption levels in 2020 are far in excess of anticipated supply, and projections of both meat and milk will have to be doubled by 2050 to meet human requirements. Strategies for productivity growth from animals are therefore urgent, and are discussed in the context of the scenario of waning agriculture, extreme poverty and hunger, food crisis, the current contributions from the components of the animal industries, prevailing constraints, opportunities and strategies for improved production. Current trends suggest that the non-ruminant pig and poultry industries will continue to contribute the major share of meat and all of egg production to meet projected human needs. With ruminants by comparison, overall meat production continues to come mainly from the slaughter of numbers. Strategic opportunities exist for maximising productivity in improved production systems. These include targeting rainfed areas, development of small farms, integrated crop-animal systems, intensive application of productivity-enhancing technologies, promoting intensive use of crop residues and expanding the R&D frontiers with interdisciplinarity and farming
    systems perspectives. The issues, together with increased investments and institutional commitment, provide for expanded animal production systems and productivity which can forcefully impact on improved human welfare in Asia in the immediate tomorrow.

  18. Fulltext Synthesis of jatropha curcas-based methyl ester and ethyl ester as biodiesel feedstocks
    Azhari Muhammad Syam, Robiah Yunus, Tinia Idaty Mohd. Ghazi, Choong, Thomas Shean Yaw

    Research on the use of Jatropha curcas triglycerides as biodiesel feedstock has received worldwide attention due to its inherent characteristics. Unlike palm oil, J. curcas oil is not edible, and thus, it will not disturb the food supply. However, to the researchers' experiences with the synthesis of J. curcas, oil-based biodiesel has shown that the fuel characteristics depend largely on the type of alcohol used as the excess reactants. Transesterification reaction is chosen for this process with sodium methoxide as the catalyst. Comparison studies on the yield of esters using methanol and ethanol, as well as the impacts on the reaction rate are discussed. The effects of reaction time and molar ratio on the reaction conversion are also examined. The determination of reaction yield is based on the conversion of triglycerides into alkyl esters as the main product. The findings are described as follows: the highest percentage yield of product is attained at 96% for methanol as an excess reactant, and this is 90% when ethanol is used. The optimum conditions of parameters are achieved at 6:1 molar ratio of alcohol to triglycerides, 50 min of reaction time and reaction temperature of 65°C for methanol and 75°C for ethanol. The biodiesel properties of both ester fuels were determined according to the existing standards for biodiesel and compared to the characteristics of diesel fuel.

  19. Fulltext Assessing the competitiveness and comparative advantage of broiler production in Johor using policy analysis matrix
    Elsedig, E.A.A., Mohd, M.I., Fatimah, M.A
    International Food Research Journal, 2015;22(1):116-121.
    MyJurnal
    Malaysian poultry policy aims to provide remunerative prices for producers and to guarantee a steady supply of poultry products at stable and affordable prices to consumers. Broiler meat is the most important and the cheapest protein source in Malaysia and trade protection could stimulate the local industry and enhance food security. The study attempts to evaluate the competitiveness and comparative advantage of three different scales of broiler production in Johor using policy analysis matrix (PAM). The existing protection and the level of comparative advantage are ascertained through PAM indicators. The results show that Malaysia has strong competitiveness position in every scale of broiler production especially the largest scale. But, the protection through import curtailment resulted in higher domestic prices than the world price. To increase competitiveness, the broiler industry should reduce the dependence on expensive and unstable cost of corn based feed.
