this experiment was carried out for a period of 4 weeks with 240 day old straight- run broiler (cobb-500) chicks to investigate the effects of administering electrolytes in drinking water on the productive performance (live weight, body weight gain, feed consumption, feed conversion and water consumption) and to determine the economic impact of using electrolytes. the chicks were randomly distr...

The aim of the research was to determine live body weight, carcass percentage, and percentage abdominal fat in broiler chicken affected by herbal drinks.One hundred twenty birds DOC used research. Basal diet contain metabolizable energy 3000 kcal/kg crude protein 22%.Experimental design completely Randomized Designed with 6 treatments 4 replicates, every replicates consist five 5 birds. were as...

Utilizing a moderate rearing temperature regimen, two trials were conducted to determine the effect of dietary energy level on the amount of abdominal fat deposited when broilers are grown to equal body weight by varying growth time. The most abdominal fat (2.29% average of live weight for male and females) was produced by broilers offered a diet calculated to contain 3325 ME kcal/kg. The least...
