Supplementation Effect of Plus Complete Feed Contains ZnSO4 and Zn-Cu Isoleusinateon EffisiencyReproduction Post Partum of Bali CowsRaised in Semi Intensive

Abstract

An experiment was conducted aiming to apply a formulae technology package of Plus Complete Feed (PCF) containing ZnSO4 and Zn-Cu isoleusinate oneffisiency reproduction in post partum of Balicows raised in a semiintensive system. The PCF technology package was formulated of various local feed consisting of corn meal, rice bran, fish meal, coconut oil and salt. The PCF containing17% crude protein and 78% TDN. The research used 27post partum Bali cows. Randomized block design with three treatments and 9 replicates each was applied in the study. Treatments offered are: basal diet in the pasture without supplementation (R0); Gliricidia leaves supplement with basal diet (R1) and basal diet with CFP supplement containing 150 mg ZnSO₄ kg^-1 DM of PCF and 2% Zn-Cu isoleusinate kg^-1 DM of ration (R2). The PCF supplement was offered once daily in the morning after the animal consuming dry grass in pasture. Variable studied are plasma glucose, plasma protein, estrous cycles, and weaningweight. The result shows that treatments have significantlyeffect (P <0.01) on all parameters studywhereas that highest effect (P <0.05 ) is on supplementing 150 mg ZnSO₄. kg^-1 DM of PCF and 2% Zn-Cu isoleusinate kg^-1 DMof ration
