摘　　要：选取18日龄肉鸡80羽,随机分为4组,分别为组Ⅰ、组Ⅱ、组Ⅲ、组Ⅳ,其中组Ⅰ、组Ⅱ、组Ⅲ为试验组,组Ⅳ为对照组。每组5个重复,每个重复4羽(♀)。采用单因子随机分组设计,各组基础日粮相同。组Ⅰ、组Ⅱ、组Ⅲ分别添加1%、3%、5%的松针粉,对照组饲喂基础饲料+抗生素。试验期为56 d,在7周龄和9周龄时,分别从每个组每个重复选取5只接近平均体重的肉鸡进行屠宰试验和肉品质分析。结果表明:7周龄时,组Ⅰ、组Ⅱ、组Ⅲ和对照组的屠宰率各组间差异不显著(P>0.05);9周龄时,屠宰率对照组显著高于组Ⅰ、组Ⅱ、组Ⅲ(P<0.05),组Ⅰ、组Ⅱ、组Ⅲ间差异不显著(P>0.05)。7周龄、9周龄时,腹脂率各组间差异不显著(P>0.05)。添加松针粉对肉鸡肌肉pH值、蛋白质、脂肪、粗灰分影响不明显。4周龄、7周龄时,添加1%、3%、5%的松针粉能有效促进肉鸡脾脏、胸腺和法氏囊免疫器官的发育,促进机体的细胞免疫水平,提高机体的抗病能力,尤其是添加5%松针粉组促进免疫器官发育效果明显,7周龄时添加3%松针粉组效果较明显。综合考虑屠宰性能、免疫功能、经济效益,本试验中3%松针粉组饲喂肉鸡效果较明显,达到抗生素组水平。80 eighteen-day-old broilers,were randomly divided into 4 groups,each with five duplicates,each duplicate with 4（♀）.Upon the variance test examination,the initiate weight of each group did not have distinctive difference（P〉0.05）.In the randomized single-factor design,the basic diets of each group were the same.For the experimental groupⅠ,the diet was added with 1% of pine needle powder,for the experimental groupⅡ,3% of pine needle powde was added,for the experimental groupⅢ,5% of pine needle powder was added.Group 4 was the basic diet control group.The trial period was 8 weeks.The slaughter performance was observed.The results showed that the addtion of pine powder showed no significant influence on chicken slaughtering performance and meat quality.at 4-7 weeks,1%,3%,5% of the pine powder could promote effectively the development of the immune organs,i.e,spleen,thymus and bursa,promote the body cellular immune level,and improve the body＇s resistance,especially in the 5% pine powder group,the effect was obvious.Over 7 weeks in the 3% pine powder group,the effect was obvious and the 3% group showed the best effect.Taking the slaughter performance,immune function,economic benefit into consideration,in this experiment the addition of 3% of pine needle powder feeding chicke had obvious effect,achieving the level of the antibiotics group.
