Objective: This study aimed to investigate the replacement effect of noug-cake (NC) with lablab purpureus seed (LPS) on biological performance of Woyito-Guji goat.
Material and Methods: About 24 intact male Woyito-Guji bucks having a preliminary weight of 17.34kg were allocated to one of the 4 investigational treatments in a randomized complete block design (RCBD). 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 sunflower seed (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 consumed the T1 and T4 over the bucks consumed the T2 and T3. Similarly, goats consumed T1 and T4 gained more (p<0.001) average-daily-gain (ADG), hot carcass weight (HCW), and rib eye muscle area (REMA) than bucks that 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 biological performance of goat.
