Abstract
The aim of the present study was to investigate the effects of adding compound enzyme with different zymogram in miscellaneous meal diets on laying performance and eggs quality of laying hens. A total of 1 140 heathy and 300-day-old HyLine Brown hens with similar body weight and laying rate were chosen and divided into five treatment groups with three repeats in each group and 96 layers in each repeat. The control group 1 fed corn-soybean meal diets without compound enzyme;the control group 2 fed corn-miscellaneous meal diets without compound enzyme;the experimental group 1, 2 and 3 fed corn-miscellaneous meal diets adding compound enzyme No.1, No.2 and No.3, respectively. The experimental period lasted for 70 d. The laying performance and eggs quality related indexes of the laying hens in the tested groups were recorded and statistically evaluated. The results showed that compared with the control group 2, the laying rate, average egg weight, daily feed intake and egg production of experimental group 1, 2 and 3 were significantly higher (P<0.05), feed-egg ratio was significantly lower (P<0.05), and the change range of experimental group 3 was the sharpest. No significant differences of laying rate, daily feed intake and feed-egg ratio between experimental groups and control group 1 were observed (P>0.05). There were no significant differences of eggs quality related indexes between experimental groups and control groups (P>0.05). Compared with control group 2, an increasing trend in shell thickness in experimental groups was observed, and the increased range of experimental group 3 was the sharpest. It was indicated that the laying performance of laying hens fed with corn-miscellaneous meal diets adding compound enzyme was similar with that of laying hens fed with corn-soybean meal diets. The improvement effects of compound enzyme with different zymogram on laying performance and egg quality of laying hens varied, and the compound enzyme No.3 with higher content of xylanase and protease was preferred in production practice.关键词
