摘要
采用2因子多水平试验设计研究了亚麻油日粮抗感染柔嫩艾美耳球虫的效力。结果表明:感染球虫显著地影响试鸡的增重率(P<0.05);感染组试鸡的日采食量均大于不感染组,但差异不显著(P>0.05);根据抗球虫指数ACI的公式计算获得,4%亚麻油日粮抗球虫指数为145,6%亚麻油抗球虫日粮指数为147,8%亚麻油的日粮抗球虫指数达162.7。该研究证明适宜比例的亚麻油日粮能防止球虫的感染。
An experiment with two factors and multilevel was conducted in the broiler chicks. The results showed that the growth rate of chick's infection with coccidiosis was significantly influenced (P<0.05); The ratio intaking of inoculated group was more than uninfected group, but the odds was inapparent (P>0.05). According to the calculation formula of anticoccidial index (ACI), the dietary supplementation with 4% levels flaxseed oil was 144.5; 6% levels flaxseed oil was 147; 8% levels flaxseed oil was 162.7.
