摘要
使用饲料添加剂抗生素的替代品——GM助长乐,可以提高肉鸭免疫力、促进生长、提高饲料利用率,并能有效地解决抗生素残留问题,长久使用会降低死淘率。试验初步研究了GM助长乐对肉鸭生产性能的影响。试验设计采用单因子设计分组,选用健康的0日龄樱桃谷雏鸭2 900只,随机分成2组,每组3个重复,实验组每个重复490只。对照组每个重复477只。各组内雏鸭平均初始重差异不显著(P>0.05),试验期48d。试验结果表明,在48日龄时,实验组料肉比低于对照组,差异显著(P<0.05);只均重比对照组高9.43g;实验组死亡率(3.13%)低于对照组(3.70%)。
As a kind of substitute of antibiotics, GM health promotion can improve duck immunity, growth and feed utilization, also can solve the problem of antibiotic residue, and decrease mortality rate. The effect of GM health promotion on growth performance of meat duck was conducted in this study. Single experimental design was adopted, 2900 1--d--old cherry valley ducks were selected and randomly assigned to 2 groups, with 3 replicates in each group, 490 birds in each replicate and 477 birds in control group. The average birth weight was no significant difference, the experiment period was 48 days. The results showed that on 48--d--old feed gain ratio of experimental group was better than control group P〈0.01）, average weight was higher than control group for 9.43g, mortality of experimental group（3.13%） was lower than control group（3.70%）.
