Performance of Kacang Goats Fed Chemically and Biologically Treated Durian Husk.

Background: Feed is one of the most important parts of the livestock production system because it can account for 60-80% of production costs, besides that very elements needed by livestock to grow, develop and produce. A study has been conducted to evaluate the effects of chemical and biological urea-treated durian husk on the production performance of Kacang female goats. Methods: The research method used was plotted in the 2 × 3 factorial randomized block design (RBD). The first factor was two processing methods of urease (A) and fermentation (F) and the second factor was three levels of urea, namely 1.0% (L1), 2.5% (L2) and 5% (L3), with four replicates as groups. The data were analyzed using analysis of variances and mean comparison using the least significant difference (LSD) test. Result: The results showed however, the application of durian husk with different urea levels produced a significant effect (P<0.05) on the body weight gain, hematocrit value, non-carcass weight and percentage, internal non-carcass weight and percentage, as well as non-carcass weight and percentage, of Kacang female goats. That administration of chemically and biologically processed durian fruit husk supplemented with urea up to 5.0%, can be implemented without negative effects on production performance, physiological conditions, carcass characteristics, as well as non-carcass characteristics.
