摘要
摘要:用四种饲料在冬季饲喂矮小型蛋鸡,A组为对照组(基础日粮),B组日粮是基础日粮添加0.5%油脂和500g/T和美酵素,C组日粮是基础日粮添加1.4%油脂,D组日粮是在基础日粮基础上加500g/T和美酵素,试验期11周。结果表明:添加500g/T和美酵素的D组产蛋率最高(77.7%),和其他三个组差异达到显著水平(P<0.05),试验期料蛋比2.21∶1,每只鸡毛利3.52元,比对照组和加油组分别提高0.45元和0.79元;同时结果还发现,和美酵素和油脂同时使用效果不好。
Four types of feeds were used to feed dwarf hens in winter for11weeks.Group A was the control group using the basal diet.Group B was fed basal diet adding0.5%fat and Hemicell500g /T.Group C was basal diet adding1.4%fat.Group D was fed basal diet adding Hemicell500g /T.The results showed that the egg production of group D was significantly higher than other three groups(P<0.05).FCR of group D was2.21∶1and the gross profit per hen got3.52yuan during the testing period,0.45yuan and0.79yuan more than group A and group C respectively.The result also showed that adding Hemicell and fat together in the feed could not get a good result.
