Goat caseous lymphadenitis (CLA) is a chronic disease caused by Corynebacterium pseudotuberculosis. However, there is paucity of data about goat's acute phase response during the course of CLA. This study was conducted to investigate the response of acute phase proteins, mainly haptoglobin (Hp), serum amyloid A (SAA) and the negative acute phase response, especially albumin after an experimental challenge of C. pseudotuberculosis and phospholipase D (PLD) in Cross bred Boer goats.
This study aims to assess the effect of Eurycoma longifolia aqueous extract on chilled and cryopreserved quality of bull sperm. Semen samples were obtained from four Simmental-Brangus. Each sample was divided into two fractions: the first fraction was used for chilling the semen, and the second fraction was used for the freezing process. Both fractions were extended with Tris-egg yolk extender supplemented with 0.0, 0.25, 0.5, 1.0, 2.5, 5.0, and 7.5 mg/ml Eurycoma longifolia aqueous extract. The diluted chilled fraction was chilled at 5 °C for 6 days, whereas the frozen-thawed fraction was frozen in liquid nitrogen. Data revealed that 1 mg/ml E. longifolia aqueous extract yielded significantly (p
