- Abstract
The aim of this experiment was to compare the metabolizable energy value and apparent metabolic rate of nutrients between corn and wheat in AA broilers and yellow-feathered broiler, so as to provide theoretical basis for the application of corn and wheat diets in poultry production. Two metabolic tests were conducted on AA broilers and yellow-feathered broiler with the same age and similar body weight: (same age test) at the age of 18 days, 96 birds were selected from each of the AA broilers and yellow-feathered broilers, for a total of 192 birds. AA broilers and yellow-feathered broiler were randomly divided into two experimental treatment groups, each treatment group had 8 replicates, and each replicate had 6 chickens; (same weight test) 96 AA broilers and 96 yellow-feathered broiler were selected respectively when the body weight of the experimental chickens reached 600 g. the experimental design group was consistent with that of the same age test. The results showed that the AME, AMEn, apparent metabolic rate of crude protein and crude fat of corn in AA broilers were significantly higher than those of yellow-feathered broiler with the same body weight (P<0.05), but there was no significant difference compared with yellow-feathered broiler of the same age; AME, AMEn, the apparent digestibility of crude protein and crude fat of wheat in AA broilers were higher than those of the same age and in the same body weight, AME was significantly different (P<0.05), but the apparent digestibility of corn and wheat in AA Broilers and yellow-feathered broiler had no significant difference (P>0.05). In conclusion, the energy value and nutrient metabolism rate of corn in AA broilers were higher than that of yellow-feathered broiler with the same body weight, while the energy and nutrient apparent metabolic rate of wheat in AA broilers were higher than that of yellow-feathered broiler of the same age and weight.
