Abstract: 【Objective】 The purpose of this experiment was to investigate the application effects of replacing corn completely with wheat in diet on the production of Yellow-feathered chickens. 【Method】 A total of 1 260 healthy 1-day-old rapidly-growing Yellow-feathered male chickens were selected and randomly divided into 7 treatment groups with consistent body weight,with 6 replicates per group and 30 chickens per replicate.The 7 groups were as follows:corn-soybean meal diet (C) group,wheat completely replacing corn (W) group,wheat low-energy (WL) group,xylanase (WL+X) group,phytase (W+P) group,xylanase+phytase (WL+X+P) group,and 4-fold xylanase and phytase (WL+4X+4P) group.The experimental period was 63 days.At 57 days of age,2 birds with body weights (BW) close to the average were randomly selected from each replicate and placed into metabolic cages for a metabolic trial to determine energy utilization efficiency.At 63 days of age,broilers were weighed after fasting on a replicate basis,and average feed intake (ADFI),average daily gain (ADG) and ratio of feed to gain (F/G) were determined.Two birds with body weight close to the average were selected from each replicate for blood sampling and slaughtering to measure plasma biochemical indicators,slaughter performance,and meat quality of the breast muscle.And the tibia was separated for measurement of tibial mineral content and bone density. 【Result】 At 1-21 days of age, the ADFI of chickens in group W was significantly greater than that in group C (P<0.05),and the ADFI of chickens in group WL was significantly greater than that in group WL+X (P<0.05).At 1-42 days of age,the F/G of chickens in group C was significantly less than that in group W (P<0.05),the F/G of chickens in group W was significantly less than that in group WL (P<0.05),and the F/G of chickens in group WL+X was significantly less than that in group WL (P<0.05).At 1-63 days of age,both the ADFI and F/G of chickens in group W were significantly greater than those in group C (P<0.05),and the latter was significantly less than that in group WL (P<0.05);the F/G of chickens in group WL+X was significantly less than that in group WL (P<0.05).The breast muscle rate of chickens in group WL+X was significantly greater than that in group W (P<0.05),the breast muscle rate of chickens in group WL+4X+4P was significantly greater than that in group C (P<0.05).The energy utilization rate of chickens in group WL+4X+4P was significantly greater than that in the other four groups except groups C and WL+X+P (P<0.05),the energy utilization rate of chickens in group C was significantly greater than that in group W and group W+P (P<0.05).The drip loss of breast muscle of chickens in group W was significantly less than that in groups WL+X and WL+4X+4P (P<0.05). 【Conclusion】 The addition of xylanase complex to wheat-based diets of Yellow-feathered chickens was conducive to improving feed utilization rate,saving dietary energy,reducing broiler mortality,while supplementing phytase could save the use of inorganic phosphorus and improve carcass quality.
