The Effects of Substitution of Corn Meal from the Concentrate of Plus-Complete Feed with Fermented Cocoa Pod on Growth of the Young Male Bali Cattle

The study aimed to evaluate the effects of substitution of corn meal from concentrate of plus-complete feed (PCF) with fermented cocoa pod (FCP) on growth of the young male Bali Cattle. Fifteen young male Bali Cattles were randomly assigned into five groups for the substitutions of corn meal from the PCF by FCP treatments i.e 0, 25, 50, 75 and 100 % which each group was replicated by three subgroups. The pods were fermented with yeast Aspergillus niger that had been activated by the combinations of sugar, urea, NPK fertilizers, and various levels of ZnSO4 and Zn-Cu isoleusinate. The best fermented cocoa pod, that produced NH3 and VFA in in vitro experiment, was used in the study. The results of the study showed that substitutions of corn meal from the PCF by 100% FCP decreased signifikantly (P<0.01) Zn and Cu status, energy and N retention, and body weight gain of the young male Bali Cattles. However, the substitutions by 0 %, 25% and 50% FCPs, those values did not decrease significant. Despite of corn meal substitutions of PCF by FCP did not decrease significantly plasma glucose and protein consumption, but substitution by FCP between of 0 % and 25 % did not decrease significantly protein consumption. In conclusion: the substitution of corn meal from the PCF by the FCP at the level up to 50% can be applied without disturbance the growth of the young male Bali Cattle.
