Improving the Performance of Local Kacang Goats Using Ruminally Undegradable Protein Feeds

摘要

Objective: This study was set up to increase the productivity of Kacang goats using fish meal and soybean meal (containing relatively high ruminally undegradable protein) in the ration. Materials and Methods: Twelve kacang goats, 1-1.5-year-old, 17.84+1.57 kg were used in this study. A completely randomized design was used with 3 different rations: NG (control) = Natural grass, FM = Total Mixed Ration (TMR) containing fish meal and SBM = Total mixed ration containing soybean meal. The rations contained 15% of crude protein and 1% of the mineral mix, except for NG. Water and feed were provided ad libitum. Data were analyzed by analysis of variance using the SPSS statistics software version 19. Results:The growth of FM goats (ADG = 59.03 g) and SBM goats (ADG = 80.06 g) were higher than that of NG goats (ADG = 27.22 g). However, the slaughter weight, carcass weight and dressing percentage of goats fed TMR containing soybean meal (SBM) were the highest among all of the treatments with having the lowest of non-carcass (%). The meat, bone and fat of SBM carcass are also the highest among others. The chevon fat content of goats fed Natural Grass (NG) was the highest, while other physical and chemical properties of chevon were relatively the same. Conclusion: It can be concluded that the use of fish meal and soybean meal in the ration improved the performance of local kacang goats. In fact, soybean meal in the ration can improve the productivity and carcass products of kacang goats better than fish meal.
