蚯蚓粪作为肉鸡垫料的应用研究

[目的]研究蚯蚓粪作为肉鸡垫料的效果。[方法]以锯屑做垫料为对照,以蚯蚓粪垫料为处理,记录不同处理肉鸡初始体重3、0日龄体重、末体重、采食量、死亡鸡只数,计算生产性能和料重比,同时测定畜舍内NH3浓度和垫料中的球虫卵囊数量。[结果]蚯蚓粪组的NH3浓度极显著低于锯屑组,同时,畜舍内相对湿度明显降低。蚯蚓粪组球虫卵数量低于锯屑组,有利于控制60日龄前鸡的球虫病。肉鸡垫料中的球虫卵在30日龄前随日龄逐渐升高,30日龄达到高峰,以后逐渐下降,至70日龄降到最低。0~70日龄,蚯蚓粪组可提高日增重6.74%,采食量1.72%,成活率2.94%,降低料重比4.58%。[结论]蚯蚓粪作为肉鸡垫料的效果好于锯屑。

Application Research on Wormcast Used as Bedding Material of Broiler

[Objective] The research was to study the effect of wormcast used as bedding material of broiler.[Method] With the bedding mterial of sawdust as CK and the bedding material of wormcast as treatment,the initial body weight,body weight at 30 days old,end weight,feed intake and died chicken number of broiler in different treatments were recorded,the performance and ratio of feed to gain were calculated,and the concn.of NH3 in livestock house and the number of coccidia oocysts in bedding material were determined.[Result] The concn.of NH3 in wormcast group was obviously lower than that in sawdust group and the relative humidity in livestock house was decreased obviously.The number of coccidian oocysts in wormcast group was lower than that in sawdust group,which was helpful to control the coccidiosis of chicken before 60 days old.The coccidian oocysts in bedding material of broiler was increased gradually with the day age of broiler before 30 days old,and reached the peak at 30 days old and then decreased to the lowest at 70 days old.During 0-70 days old,the wormcast group could increase the daily weight gain by 6.74%,feed intake by 1.72%,survival rate by 2.94% and decrease the ratio of feed to gain by 4.58%.[Conclusion] The effect of wormcast used as bedding material was better than that of sawdust.
