Effects of Diets Including Different Levels of Protein and Energy on Broilers Performance
Abstract
This study aimed to investigate the effects of different energy and protein levels of diets on
broiler performance. Two hundred and eighty eight broilers were used. and fed during 42 days. The
birds were divided into three treatment groups. These groups received following diets: 1. group; 24 %
crude protein, 3200 kcal/kg ME, 2. group; 23 % crude protein, 3100 kcal/kg ME, 3. group; 22 %
crude protein, 3000 kcal/kg ME during 10 days from the beginning of experiment. 1. group; 23 %
crude protein, 3200 kcal/kg ME, 2. group; 22 % crude protein, 3100 kcal/kg ME, 3. group; 21 % crude
protein, 3000 kcal/kg ME between 11–21 days. 1. group; 22 % crude protein, 3200 kcal/kg ME, 2.
group; 21 % crude protein, 3100 kcal/kg ME, 3. group; 20 % crude protein, 3000 kcal/kg ME between
22–42 days. It was found that increasing crude protein and energy levels in broiler rations increased
live weight gain. As a result, it was seen that growth and feed conversion ratio of broilers were
affected by energy and protein level of the diet.
