MATERIALS AND METHODS: Twenty-four male Awassi lambs (initial body weight, 17.33 ± 0.821 kg; age, 75 ± 1.5 days) were randomly allocated to three dietary treatments (n = 8/group): control (CON; 0 g/kg BAWA), BAWA100 (100 g/kg BAWA), and BAWA200 (200 g/kg BAWA) on a dry matter (DM) basis. The 73-day experiment comprised 10 days of adaptation and 63 days of data collection. Nutrient intake, growth performance, feed efficiency, and feeding costs were determined. Five lambs per group were used for digestibility and N balance assessment. Carcass characteristics, meat quality, FA composition, and serum biochemical indicators were also evaluated.
RESULTS: BAWA100 and BAWA200 increased DM, crude protein (CP), and metabolizable energy intake compared with CON (p < 0.02). BAWA200 increased final body weight, total gain, and average daily gain and improved feed efficiency (p ≤ 0.007). The cost of gain was lower with BAWA200 (p < 0.001). DM and CP digestibility increased with BAWA200, while N retention improved with both BAWA treatments (p < 0.05). Fasting live weight, hot and cold carcass weights, and carcass cut weights were greater with BAWA200 (p ≤ 0.03). Dietary BAWA did not adversely affect meat quality or FA composition. Most serum biochemical indicators remained unaffected, whereas aspartate aminotransferase was numerically lower (p = 0.051) and alanine aminotransferase activities were lower in BAWA-fed lambs (p ≤ 0.05).
CONCLUSION: Dietary inclusion of BAWA, particularly at 200 g/kg DM, improved growth performance, nutrient utilization, N retention, carcass yield, feed efficiency, and economic outcomes without compromising meat quality, FA composition, or health indicators. BAWA can therefore serve as a practical alternative to conventional concentrate ingredients in growing Awassi lamb diets while supporting more economical and sustainable small-ruminant production.
OBJECTIVES: The objectives of this study were to investigate the effect of adherence to postoperative recommendations on anthropometric measurements and body composition and assess the percentage of total weight loss (%TWL) and excess weight loss (%EWL) 3 months postoperative.
SETTINGS: Fifty-two participants who underwent a Roux-en-Y gastric bypass or sleeve gastrectomy in the University of Jordan Hospital were included.
METHODS: Participants have filled out a preoperative questionnaire. Anthropometric measurements were obtained preoperative and 3 months postoperative using a Body Impedance Analyzer (Inbody 270). The adherence to postoperative recommendations was assessed by the Bariatric Surgery Self-management Questionnaire 3 months postoperative and classified to 3 adherence levels.
RESULTS: Most anthropometric measurements decreased 3 months postoperative in the 3 adherence groups (P ≤ .05). No significant differences were observed between groups in anthropometric measurements and body composition, except for minerals and visceral fat levels. The mineral loss has decreased in both the high and intermediate adherence groups (-.09 ± .22 kg, and -.09 ± .18 kg, respectively). Also, the high adherence group showed less loss in protein amount postoperatively (P = .06). Visceral fat level decreased in the high adherence group (P ≤ .05).
CONCLUSIONS: Adherence to postoperative behavioral and nutritional recommendations was associated with less protein and mineral loss and enhanced visceral fat reduction postoperatively.
