Effects of Supplementing Crude Glycerin in Concentrated Diet and Castration on Carcass Characteristics and Meat Quality of Thai Native x Anglo Nubian Goats
Keywords:Goat meat, castration, crude glycerin, fat distribution
AbstractThe effects of feeding concentrate diet containing crude glycerin supplementation and castration on carcass composition and meat quality of Thai Native x Anglo-Nubian (TN-AN) goats were investigated. Twenty TN-AN goats at the age of 12 months old with 24.75±1.33 kg initial live weight were allotted into a 2x2 factorial arrangement in completely randomized design when factor A was assigned for sexes (intact and castrated male) and factor B was assigned for 2 types of concentrate diet (control diet and diet supplemented with 10 % crude glycerin). Goats were intensively raised in individual pens with ad libitum water and Atratum grass (Paspalum atratum), while 2 % of concentrate diets was provided. After 90 days of feeding, 3 goats from each treatment combination were randomly sampled and sacrificed for further examination. From the study, castrated male goats had significantly higher slaughter and carcass weight, carcass fat percentage and chemical fat percentage than those of the intact males (P < 0.01). In addition, muscle from castrated male goats was more tender and lighter in color as compared with intact male goats (P < 0.01). Goats receiving a diet with extra glycerin had significantly higher weight at slaughter, warm carcass weight, carcass fat, and chemical fat percentages than those on the control diet. Therefore, it could be concluded that feeding goats with a diet of 10 % supplementary glycerin and castration could lead to better slaughter and warm weight, whereas a higher fat content in the carcass and muscle are observed.
