摘要
为研究添加不同浓度的酵母硒对吉林芦花鸡生产性能、蛋硒含量、蛋品质、鸡蛋胆固醇含量的影响,试验选用健康的21周龄吉林芦花鸡96只,平均体重1622 g。随机分成4组,每组6个重复,每个重复4只鸡。对照组饲喂基础日粮,其他3组分别添加0.3、0.6、0.9 mg/kg的酵母硒。预试期5 d,正式期21 d。结果表明:各组间料蛋比、采食量、哈氏单位、鸡蛋颜色无显著差异(P>0.05);0.3 mg/kg酵母硒组的平均蛋重极显著低于其他3组(P<0.01),产蛋率、软破壳蛋率均极显著高于其他3组(P<0.01);0.6 mg/kg酵母硒组的蛋黄比率、软破壳蛋率极显著低于其他3组(P<0.01);0.9 mg/kg酵母硒组胆固醇含量极显著低于其他3组(P<0.01);料蛋比(P=0.087)和胆固醇(P=0.061)随着酵母硒添加量的增加有降低的趋势。0.6 mg/kg酵母硒组蛋硒含量极显著高于对照组和0.3 mg/kg酵母硒组(P<0.01),显著高于0.9 mg/kg酵母硒组(P<0.05)。综上,在本试验条件下,酵母硒适宜添加量为0.6 mg/kg。
In this paper,the effects of different concentrations of yeast selenium on the performance,egg selenium content,egg quality and egg cholesterol content of Jilin Luhua chicken were studied.96 healthy 21-week-old Jilin Luhua chickens with an average weight of 1622 g were selected.They were randomly divided into 4 groups,6 replicates in each group,4 chickens in each replicate.The other three groups were added0.3,0.6 mg/kg and 0.9 mg/kg yeast selenium respectively.The pre-trial period was 5 days,and the formal period was 21 days.The results showed that there were no significant differences in feed to egg ratio,feed intake,Haugh’s unit and egg color among the four groups(P>0.05);the average egg weight of 0.3 mg/kg yeast selenium group was significantly lower than that of the other three groups(P<0.01),the egg production rate and soft broken egg rate were significantly higher than those of the other three groups(P<0.01);the egg yolk ratio and soft broken egg rate of 0.6 mg/kg yeast selenium group were significantly lower than those of the other three groups(P<0.01).The cholesterol content of 0.9 mg/kg yeast selenium group was significantly lower than that of the other three groups(P<0.01);the feed to egg ratio(P=0.087)and cholesterol(P=0.061)decreased with the increase of yeast selenium.The egg selenium content of 0.6 mg/kg yeast selenium group was significantly higher than that of the control group and 0.3 mg/kg yeast selenium group(P<0.01),significantly higher than that of 0.9 mg/kg yeast selenium group(P<0.05).In conclusion,under the condition of this experiment,the suitable addition of yeast selenium was 0.6 mg/kg.
