摘要
该试验选取健康体重接近的1日龄白羽肉鸡90只,随机分为3组,每组30个重复进行饲喂试验,试验期为42 d。分别对试验动物在28日龄和42日龄2个时间点进行采样。结果证明,添加0.6%黄芩、黄芪等比例中草药粉混合物可有效提高早期(28日龄)白羽肉鸡日增重(P<0.05),显著增加胸腺指数和脾脏指数(P<0.05),提升肉鸡肠道长度和十二指肠绒毛长度(P<0.05)。42日龄白羽肉鸡屠宰结果显示,添加0.6%黄芩、黄芪等比例中草药分混合物可有效提高白羽肉鸡屠宰率(P<0.05)。结果表明,饲粮中添加等比例黄芪、黄芩中草药粉对白羽肉鸡的生产性能以及屠宰性能具有积极作用,促进肉鸡肠道生长发育,提升饲料营养吸收。建议在白羽肉鸡饲粮中黄芪、黄芩等比例中草药粉添加量为0.6%。
In this experiment,90 healthy one-day-old White Feather broilers with similar body weights were randomly divided into three groups,each with 30 replicates.The experimental period lasted 42 d.Samples were taken from the experimental animals at two time points,28 d and 42 d.The results demonstrated that adding a 0.6%mixture of Scutellaria baicalensis and Astragalus membranaceus in equal proportions significantly increased the average daily gain(P<0.05)of White Feather broilers at an early stage(28 days),significantly enhanced the thymus and spleen indices(P<0.05),and increased the intestinal and villous length(P<0.05).The slaughter results at 42 days indicated that the addition of a 0.6%mixture of these herbal components effectively improved the slaughter rate of White Feather broilers(P<0.05).The findings suggest that herbal feed additive promotes early growth in White Feather broilers and has a positive effect on slaughter performance,promoting the intestinal growth and development of broilers and improving the nutrient absorption of feed.It is recommended to add 0.6%herbal components to the feed for White Feather broilers.
