【摘要】：本试验旨在研究饲粮中添加茶树油对育肥猪生长性能、器官指数、胴体性状和肉品质的影响。试验选用64头初重为(68.13±0.46)kg的健康"杜×长×大"三元杂交生长育肥猪,随机分为4组,每组4个重复,每个重复4头猪(公母各占1/2)。对照组饲喂基础饲粮,试验组饲喂在基础饲粮中分别添加100、200和300 mg/kg茶树油的试验饲粮,预试期10 d,正试期56 d。结果显示:1)与对照组相比,200和300 mg/kg组末重和平均日增重显著增加(P0.05),100和200 mg/kg组料重比显著降低(P0.05);2)与对照组相比,200和300 mg/kg组肝脏指数显著增加(P0.05),300 mg/kg组肾脏指数显著增加(P0.05);3)与对照组相比,200 mg/kg组背最长肌红度值、p H24 h显著增加(P0.05),100和200 mg/kg组背最长肌剪切力显著降低(P0.05)、肌内脂肪含量显著增加(P0.05)。结果表明,饲粮中添加不同剂量的茶树油对育肥猪的生长性能、器官指数和肉品质有不同程度的影响,其中基础饲粮中添加200 mg/kg茶树油对育肥猪生长性能和肉质的改善效果较好。
[Abstract]:The purpose of this experiment was to study the effects of tea tree oil on growth performance, organ index, carcass traits and meat quality of fattening pigs. 64 healthy "du 脳 long 脳 big" crossbred pigs with initial weight of 68.13 卤0.46)kg were selected. They were randomly divided into 4 groups, each group with 4 replicates. Each repeated 4 pigs (male and female accounted for 1 / 2%). The control group was fed with basic diet, the experimental group was fed with 100200 and 300 mg/kg tea tree oil in the basal diet, and the control group was fed with 100200 and 300 mg/kg tea tree oil, respectively. The results showed that: 1) compared with the control group, the end weight and average daily gain of the 200 and 300 mg/kg groups increased significantly, the feed weight ratio of the 100 and 200 mg/kg groups decreased significantly (P 0.05) compared with the control group, the liver index of the 200 and 300 mg/kg groups increased significantly. Compared with the control group, the erythrocyte value of the longissimus dorsi muscle in the 200 mg/kg group and the 200 mg/kg group increased significantly at 24 h. The shear stress of the longissimus dorsi muscle decreased significantly, and the content of intramuscular fat increased significantly. The results showed that, in comparison with the control group, the kidney index of the P0.05 mg/kg group was significantly higher than that of the control group. The results showed that the blood pressure of the longissimus dorsi muscle in the 200 mg/kg group was significantly higher than that in the control group at 24 h. The effects of different doses of tea tree oil on growth performance, organ index and meat quality of fattening pigs were different, and the growth performance and meat quality of fattening pigs were improved better by adding 200 mg/kg tea tree oil to basal diet.
