Body weight gain, dressing percentage, abdominal fat and serum cholesterol of broilers supplemented with a microbial preparation

Abstract

A study was conducted to study the effects of supplementation of a microbial preparation, Effective Micro organisms (EM), on body weight gain, dressing percentage, abdominal fat and serum cholesterol content of broilers. The EM was added to drinking water at a rate of 1 part EM to 1000 parts of water. The two treatments were control (0 EM) and 1 EM.
