摘要
选择3年龄皖西白鹅产蛋种鹅90只,分成3个处理组:试验1组、试验2组、试验3组,每组30只,设6个重复,每个重复5只(1公4母)。试验1组、试验2组、试验3组饲喂的日粮代谢能、蛋白质水平分别为10.83 MJ/kg、14%;11.33 MJ/kg、14.65%;11.83 MJ/kg、15.30%。试验期30d。结果表明:试验3组产蛋性能比试验2组(P>0.05)、试验1组(P<0.05)都高。试验3组料蛋比比试验2组(P>0.05)、试验1组(P<0.05)都低。试验3组入孵种蛋数比试验2组(P>0.05)、试验1组(P<0.05)都有一定程度的提高;试验2组(P>0.05)、试验3组(P>0.05)入孵蛋健雏率比试验1组都高;试验3组健雏数比试验2组(P>0.05)、试验1组(P>0.05)都有一定程度提高。试验2组、试验3组种鹅只均利润比试验1组分别多7.39、16.43元。整个试验期间,试验3组日粮饲喂的皖西白鹅种鹅繁殖性能最高。
90 Wanxibaie breeder geese （3 years ） were randomly assigned to three groups with 6 replicates each, 5 birds per replicate, and fed with diets of different metabolizable energy and protein levels （group 1,10. 83 MJ/kg, 14. 00%group 2, 11.33 MJ/kg, 14. 65% and group 3,11.83 MJ/kg, 15.30%）. The experiment lasted 30 days. The results showed that the lay- ing performance of group 3 was higher than group 1 （P〈0.05）and group2 （P〈0.05）, and the ratio of feed to egg of group 3 was lower than group 1 （P〈0. 05）and group2（P〈0. 05）~and the hatching eggs of group 3 were more than group 1 （P〈0. 05） and group2 （P〈0. 05）, the hatching rate of healthy for group 2 and group 3 was higher than group 1 （P〈0. 05） the percentage of healthy day-old chicks for group 3 was higher than group I（P〈0. 05）and group2（P〈. 05） the average profit of group 2 and group 3 were 7. 39 yuan and 16.43 yuan higher than group 1 respectively. Throughout the trial period, the reproductive performance of group 3 was the highest.
