Abstract
Objective: The goal of this study was to find out what happened when Noug-cake (NC) was replaced with Lablab purpureus seed (LPS) and how that affected the health and performance of Woyito-Guji goats.
Material and Methods: About 24 intact male Woyito-Guji bucks with a preliminary weight of 17.34 kg were allocated to one of the four investigational treatments in a randomized complete block design. The investigational treatments used were haricot bean haulms (HBH) ad-libitum + 18% of wheat bran (WB) + 23% of maize (MG) + 24% of sorghum (SG) + 20% of NC + 12% of sun¬flower seed (SFS) + 1.5% of common salt and 1.5% of limestone (T1); HBH ad libitum + 18% of WB + 23% of MG + 24% of SG + 20% of NC + 12% of SFS + 1.5% of common salt and + 1.5% of limestone (T1), HBH ad-libitum + 18% of WB + 22% of MG + 20% of SG + 15% of NC + 12% of SFS + 10% of LPS + 1.5% of common salt + 1.5% of limestone (T2), HBH ad-libitum + 20% of WB + 23% of MG + 22% of SG + 5% of NC + 12% of SFS + 15% of LPS + 1.5% of common salt and + 1.5% of limestone (T3), and HBH ad-libitum + 18% of WB + 23% of MG + 24% of SG + 12% of SFS + 20% of LPS + 1.5% of common salt + 1.5% of limestone (T4).
Results: The total dry matter and crude protein consumption and nutrient digestibility were higher (p < 0.001) for bucks who consumed T1 and T4 over the bucks who consumed T2 and T3. Similarly, goats that consumed T1 and T4 gained more (p < 0.001) in average daily gain, hot carcass weight, and rib-eye muscle area than bucks that were given T2 and T3.
Conclusion: The findings from this investigation pointed out that replacing NC with roasted LPS at a 20% inclusion level in goat rations improved the biological performance of goats.
