Effects of Lemuru Oil and ZnSO4 Supplementation in the Diet Consisted of Cacao Pod Silage and Urea on Zinc Absorption and Growth of Calves

TL;DRAbstract

An experiment conducted to study the effect on Zinc, prostaglandin-E2 (PGE2) concentaration, alkaline phosphatase activities (APA) in the growth of bull calves fed cocoa pod silage diet supplemented with lemuru oil (LO) and ZnSO4. The animals were randomly assigned into three group of treatments, i.e.:supplementation of 0, 25, 50 and 75 mg kg -1 diet ZnSO4 and 0, 1.5 and 3% kg -1 diet LO. Basal diet consisted of cocoa pod silage and concentrate consists of wheat bran, cassava waste, soya bean meal in the ratio 1:3 which contained 70% Total Digestible Nitrient (TDN) and 16% CP as prescribed by NRC (1988). The diet was the supplemented with 1% urea. LO and ZnSO4 supplementation in the diet was significantly increased Zinc absorption (P<0.01) as well as increased PGE2 concretation (P<0.14) in the growth of bull calves. Relationship of the rate of apparent Zinc Absorption (Va, mg.d-1) with the rate Zinc intake (Va, mg.d-1), PGE2 concentration (mg.L-1) and Vi interaction for the level of 0,
