摘要

本文旨在研究饲粮中添加巨大芽孢杆菌1259(BM1259)对蛋鸡生产性能及其排泄物中含氮物浓度的影响。选用576只300日龄健康、产蛋率差异不显著(P>0.05)的海兰褐蛋鸡,随机分为6组,每组6个重复,每个重复16只鸡。对照组饲喂基础饲粮,试验组饲粮在基础饲粮中分别添加100、150、200、250和300 mg/kg BM1259。试验期42 d。结果表明:1)BM1259可以显著提高了平均蛋重(P<0.05),极显著影响产蛋率(P<0.01),并极显著降低料蛋比(P<0.01),其中100 mg/kg组表现最佳。2)BM1259极显著降低了蛋鸡排泄物中尿素氮浓度和脲酶活性(P<0.01),显著降低尿酸浓度(P<0.05)。由此可见,在饲粮中添加BM1259能改善蛋鸡生产性能,降低排泄物中含氮物浓度。

Abstract

This research was carried out to investigate the effects of diet added with Bacillus magaterium 1259 (BM1259) on concentration of nitrogen containing compounds in excreta of laying hens.A total of five hundred and seventy-six 300-day-old healthy Hyline brown laying hens with similar laying rate were randomly assigned to six groups with six replicates per group and sixteen hens per replicate.The control group was fed a basal diet, while the other groups were fed basal diet added with BM1259 of 100, 150, 200, 250 and 300 mg/kg, respectively.This test lasted for 42 d.The result showed as follows: 1) diet added with BM1259 significantly increased average egg weight (P<0.05), and significantly affected laying rate (P<0.01), and significantly decreased the ratio of feed to egg (P<0.01).Furthermore, the optimal group was observed in 100 mg/kg group.2) Diet added with BM1259 significantly decreased concentration of urea nitrogen and urease activity in excreta (P<0.01), and significantly decreased concentrate of uric acid in excreta (P<0.05).It suggests that diet added with BM1259 can improve performance and decrease the concentration of nitrogen containing compounds in excreta of laying hens.
