| Abstract | ||
| This study was conducted in the poultry farm in-Animal production department-the faculty of Agriculture-University of Kirkuk ,The aim of this experiment was to determine the effect of using methionine and choline chloride in low protein diets on growth performance of Local quail . distributed randomly a(280) chicks (10 days old) on 7 treatments by 5 replicate for each treatment (8)birds per replicat . Birds fed the dietary treatment T1(24% crude protein(cp) ), T2(22% cp) , T3(20% cp) , T4 (22% cp +adding 20% methionine above the NRC(1994)recommended), T5 (20% cp +adding 20% methionine above the NRC(1994) recommended),T6 (22% cp +adding 20% choline above the NRC(1994) recommended), T7 (20% cp +adding 20% choline above the NRC(1994) recommended) from the age of 10-45 days. The results showed that the experimental treatments significantly (p<0.05) differed in feed intake , weight gain and feed conversion, consumption of proten, methionine and choline among treatments . The T7 was significantly higher than T2 in weight gain .The T7 was significantly (p<0.05) better than T2 and T5 in feed conversion ratio , there were no significant effect among treatments for live body weight and relative weight of heart ,liver ,gizzard ,stomach and intestine .The T1 and T3 were significantly higher than T5 in relative weight of the breast , and there were no significantly differences in the relative weight of leg among the treatments . The T5 was significantly higher than T1 ,T3,T4 and T6 in relative weight of wings. .The T7 was significantly higher than all treatments in mean of carcass weight .The T1 and T2 was significantly higher than T5 in the relative weight of the loss .The best nutritional treatment was the seventh treatment (The diet which contained 20% crud protein and 20% choline above te requirement). | ||
