Abstract

This experiment was conducted to investigate dietary crude protein (CP) level on growth performance, carcass quality, rate of protein retention and blood biochemical indices in broilers aged from 22 to 42 and 43 to 63 days of age. For both the earlier and later phases, a factorial arrangement was used to assess effects of sex (equal numbers of each) and CP level (16.0%, 17.5%, 19.0%, 20.5% and 22.0% for 21 to 42 days of age; 14.0%, 15.5%, 17.0%, 18.5% and 20.0% for 43 to 63 days of age). The experiment involved 4 replicates of 40 chickens of each sex and CP level in each growth phase (a total of 3 200 birds). Birds from each replicate was blood sampled and slaughtered to determine effects of CP on blood indices and carcass composition. The corn-soybean meal diets were formulated with different level corn, soybean meal and palm oil to make the 10 diets. The results showed as follows: at 22 to 42 days of age, 1) dietary CP levels significantly affected average daily feed intake (ADFI) of female broilers, average daily gain (ADG) and feed/gain (F/G) of male broilers (P<0.05); 2) dietary CP levels significantly affected the percentages of thigh muscle, abdominal fat and breast muscle of both sexes (P<0.05 or P<0.01); 3) dietary CP levels significantly influenced the content of triglyceride (TG), cholesterol (CHO), uric acid (UA) in serum and CP deposition of both sexes (P<0.05 or P<0.01). At 43 to 63 days of age, 1) dietary CP levels significantly influenced ADFI, ADG and CP intake of both sexes, and F/G of the males (P<0.01); 2) there was a striking effect of dietary CP levels on carcass quality (the percentages of thigh muscle, abdominal fat and breast muscle) of males (P<0.05), and also significantly influenced thigh muscle percentage of females(P<0.01); 3) dietary CP levels significantly affected rate of protein deposition (P<0.05) and the contents of TG, CHO and UA in both sexes (P<0.05 or P<0.01). In conclusion, on the basis of all criteria considered and the estimated results of regression analysis, the CP requirement of female yellow broilers at 21 and 42 days of age is 19.00% to 19.23% and the CP requirement of female yellow broilers is 19.00% to 19.41%. For 43 to 63 days of age, the CP requirement of female yellow broilers is 17.00% to 17.28% and the CP requirement of male yellow broilers is 17.00% to 18.50%.
