本试验旨在探讨日粮中添加L-茶氨酸对球虫攻毒AA肉鸡血清溶菌酶活性和粪便球虫卵囊数的影响.试验采用2×2因子试验设计,包含2种攻毒处理和2个L-茶氨酸水平(0、800 mg/kg).240只1日龄雄性AA肉鸡被随机分为4组,每组6个重复,每个重复10只.肉鸡21日龄,处理组灌喂孢子化堆型艾美耳球虫卵囊,对照组灌喂生理盐水,在试验第21、28天采血和收粪,测定血清溶菌酶含量和排泄物卵囊数.结果表明:L-茶氨酸能够显著提高球虫攻毒肉鸡血清溶菌酶含量(P<0.01),显著降低了球虫攻毒肉鸡排泄物中卵囊数(P<0.05).结果表明,L-茶氨酸对球虫攻毒AA肉鸡的免疫机能具有一定改善作用.
Effects of L-theanine on Serum Lysozyme Activity and Fecal Coccidial Oocyst in Arbor Acres Broiler Chickens Challenged with Eimeria Acervulina
To study the effects of L-theanine on serum lysozyme activity and fecal coccidial oocyst in arbor acres broiler chickens with eimeria acervulina challenge.The design of this experiment was a 2x2 factorial arrangement with two dietary concentrations of L-theanine (0,800 mg/kg) with or without Eimeria Acervulina challenge.A total of 240 one-day-old male arbor acres broiler chickens were randomly assigned into 4 groups with 6 replicates and 10 chickens per replicates.At the age of 21 d,the isodose sporulate E.acervulina oocysts and saline were respectively gavaged to chickens in control and experimental groups.On t 21 and 28,the blood and feces were collected respectively to detect the content of serum lysozyme and fecal coccidial oocyst.The results showed that L-theanine could significantly increase the content of serum lysozyme (P<0.01) and decrease fecal coccidial oocyst (P<0.05) after eimeria acervulina challenge.The result indicated that L-theanine had a benefit effect on immune function of arbor acres broiler chickens infected with Eimeria A cervulina.
