Background and Aim: To address the problems associated with the availability and prices of conventional feeds, researchers have started to include alternative feeds to reduce the cost of diets and increase profitability. This study examined the influences of olive cake (OC), either alone or in combination with Saccharomyces cerevisiae (SC), in the diet of black kids.
Materials and Methods: Thirty kids were distributed into three treatments: A free OC diet (control [CON]), OC (20% OC), and OCSC (20% OC with 1 g SC head/d). While penned individually, the kids were fed daily and allowed to acclimate to their diets and pens for 7 days. After acclimation, the kids were fed the prescribed diets for 63 days. Five kids were chosen from each group on day 50 of the feeding period and moved to the metabolic cages to evaluate nutrient digestibility and N balance. At the end of the study, all kids were slaughtered to evaluate carcass characteristics and meat quality.
Results: Feeding the OCSC diet increased (p = 0.035) DM intake for kids compared with the OC and CON. The CP intake was higher (p = 0.021) in the OCSC group than in the CON group. Growth performance parameters were higher (p ≤ 0.031) in the OCSC group than in the CON diet. Feed conversion efficiency was improved (p = 0.052) by incorporating OCSC compared with the CON diet. Consequently, economic return was enhanced (p = 0.003) by feeding the OC and OCSC groups. Kids fed the OCSC had a higher cold carcass weight (p = 0.054) than those fed the CON diet. The OCSC group also showed increased (p ≤ 0.027) loin cut and intermuscular fat weights compared with the OC and CON groups. All measured serum metabolites were similar in CON and groups incorporating OCs or OCSCs.
Conclusion: The results showed that adding 20% OC combined with SC to the diet of growing kids improved some growth and carcass characteristic parameters without affecting their health status. Notably, using OC along with SC could be an option for feed cost reduction in kids’ diets.
