EFFECT OF USING THE SACCHAROMYCES CEREVISIAE ON THE SOME PRODUCTION TRAITS AND CARCASS CHARACTERS OF THE LOCAL RABBITS

Abstract

This study was carried out to investigate the effect of Saccharomyces cerevisiae as a feed additive on some production traits and carcass of rabbits. The 24 local rabbits males age 2-3 months with the average body weight of 1.2±0.3 kg were divided randomly into three groups with eight rabbits per group. Control group, the rabbits of this group fed standard ration without additives. The rabbits of the second group were fed Saccharomyces cerevisiae (4 g/kg as feed additives), and the rabbits of the third group were fed Saccharomyces cerevisiae (5 g/kg as feed additives). The results showed that no significant effect on feed intake between all groups, the using Saccharomyces cerevisiae had highly significant increased (P< 0.05) on total weight gain, daily weight gain and final weight gain compared with control group. There was no significant effect of all treatment on blood parameters. The using Saccharomyces cerevisiae 4 and 5 g/ kg as feed additives, showed a significant effect (P
