Abstract
Vitamin C and zinc have an important role in the environment and the sustainability of chicken production. The purpose of this study was to determine the response of vitamin C and zinc supplementation to the performance and physiology of joper at various density of cage. A total of 324 experimental (unsex) chicken were used in this study. The experimental design used a complete randomized design of factorial pattern consisting of 2 factors, factor A was vitamin C and zink supplementation and factor B was cage of density, each treatment was repeated 3 times. The data were analyze by analysis of variance and continued with Dunan’s test if there was a significant effect of 0.05% level. The results showed that vitamin C and zinc supplementation had no significant effect (P>0.05) on ration consumption, body weight gain, ration conversion, rectal temperature and respiratory frequency. The parameter of densities the cage had a significant effect (P<0.05). Conclusions that vitamin C and zinc supplementation had no significant effect on the performance and physiology of joper and there was interaction on rectal temperature when vitamin C and zinc supplementation and density of cage were applied together.
