Effect of Adding Different Levels of Energy and Protein in The Production Performance of Quail

Abstract

The study was conducted in one of the research farms belong to Department of Animal Production/Faculty of Agriculture at Tikrit University for the period from 11/9/2020 to 16/10/2020 to determine the appropriate diets from energy and protein and impact on the production performance of the developing quail bird. Two Hundred – Forty eight quail chicks with age of 7-35 days. The birds were divided into two treatments, each treatment contained four replicates with 31 birds per replicate. The first treatment was fed on a diet containing 20% protein, energy ( 2800 Kcal/kg). the second treatment was fed on a diet containing 22% protein, energy ( 2900 Kcal/kg).The results showed no significant differences in body weight during first, second and fifth weeks, while there were significant differences during the third and fourth weeks while the second treatment recorded an increase as comparison with the first treatment in this descripton. And the presence of significant differences during the period 2 to 3 sevenths in the rate of weight gain and the absence of significant differences during the remaining periods and there are no significant differences between the treatments in the rate of consumption of feed during the second and third week and the presence of significant differences during the fourth week where the second treatment recorded an increase as comparison with the first treatment and the absence of significant differences during the fifth week and the total period there are no significant differences between the treatments in feed conversion efficiency during the first week and the presence of significant differences during the second week where they recorded an increase as comparison with The first treatment is on the second treatment. There were significant differences between the treatments during the third week, where the second treatment recorded an increase as comparison with the first treatment. There are no significant differences between treatments during the fifth week and total conversion efficiency.
