This experiment was conducted to determine the requirements of vitamin supplement and available phosphorus in broiler chickens from 42 to 56 days of age. In a completely randomized design, with a 3×3×3 factorial arrangement, 270 one-day-old commercial broiler chicks were divided into 27 groups (replicates) with 9 treatments, 3 replicates and 10 chicks in each group. Each of the nine diets was g...

This experiment was conducted to investigate the effect of whey via drinking water on broiler chicken performance. In a completely randomized design, whey at levels of zero, 10, 20, 40, 80, and 100% of drinking water was used for 47 days. 720 day-old broilers (Ross) were divided into 24 groups, 30 chicks per group and each experimental treatment was given to four replicates from 7-54 days of ag...

This experiment was conducted to evaluate the effects of different levels of dried lemon pulp (DLP) on performance, carcass traits, blood biochemical and immunity parameters of broilers. In this experiment 240 of broilers (Ross-308) were used in a completely randomized design with 4 treatments and 3 replicates (with 20 birds in each replicate) from 1 to 42 days.
