Efect of different dose levels of microbial feed supplement EY Micromix on broiler performance and plasma proteins profile under mid hill conditions

摘要

Supplementation of EY Micromix @ 30 g and 40g/q feed showed significantly higher gain in body weight at 1 percent and 5 percent levels of significance respectively at marketable age as compared to the chicks of control group. The feed conversion ratio (FCR) with these - dose levels was recorded to be 2.51 and 2.58 respectively in comparison to 2.74 in control chicks. Better survivability was observed in chicks received EY Micromix @ 30g and 40 g/q feed over six weeks rearing period. A non-significant increase in total plasma proteins and globulins was recorded in all the groups that recevied EY Micromix as compared to control group. However, this increase was maximum in chicks received EY Micromix @ 30g/q feed.
