- Abstract
The experiment was to study the effect of corn gluten meal on laying performance, nutrient apparent digestibility and egg quality of Hyline brown laying hens. A total of 1 500 Hyline brown laying hens were randomly divided into four groups, with five replicates in each group and 75 chickens in each replicate. The laying hens in control group were fed with basic diet, and group Ⅰ, group Ⅱ and group Ⅲ were added with 3%, 6% and 9% corn protein powder in basic diet, respectively. The pre-test period was 7 d, and the formal test period was 35 d. The results showed that the egg production rate of laying hens in group Ⅱ was significantly higher than that of other groups (P<0.05). The egg weight of group Ⅱ and group Ⅲ was significantly lower than that of control group and group Ⅰ (P<0.05), the laying rate of control group was the lowest, which was 81.46%. The average daily feed intake of laying hens in group Ⅲ was the highest, which was significantly higher than that in group Ⅱ (P<0.05). The feed to egg ratio in whole period in group Ⅱ was the lowest, which was significantly lower than that in group Ⅲ (P<0.05). The content of serum TP and ALB of laying hens in group Ⅲ was significantly lower than other groups (P<0.05), and the content of BUN was significantly higher than other groups (P<0.05). The apparent digestibility of crude protein in group Ⅲ was significantly lower than that in other groups (P<0.05). The egg yolk color of group Ⅱ and group Ⅲ was significantly higher than other groups (P<0.05), and the protein height was significantly lower than other groups (P<0.05). The experiment indicates that the addition of 6% corn gluten powder can obviously increase the egg production rate, reduce feed to egg ratio, and effectively strengthen the deposition effect of pigment in egg yolk.
