【摘要】：本试验旨在研究普通和乳化植物甾醇对育肥猪生长性能、血清生化指标和养分消化率的影响。选用75头初始重为60 kg左右的杜长大育肥猪随机分为3组,其中对照组饲喂基础日粮,试验组在基础日粮中分别添加30 mg/kg普通植物甾醇(Ⅰ组)或乳化植物甾醇(Ⅱ组)。试验期为52 d。2种植物甾醇对育肥猪生产性能无显著影响,但显著降低血清总胆固醇(TC)、甘油三酯(TG)水平和白球比(A/G)(P0.05),显著提高血清总蛋白(TP)和球蛋白(GLO)水平(P0.05),Ⅰ组血清白蛋白(ALB)含量显著低于对照组(P0.05),而Ⅱ组无显著差异;显著提高育肥猪对干物质、有机物、粗蛋白的消化率(P0.05),Ⅱ组粗脂肪消化率亦显著高于对照组(P0.05)。结果显示,在育肥猪日粮中添加30 mg/kg 2种植物甾醇可改善养分消化率,调节血脂和蛋白质代谢,且从血清ALB和粗脂肪消化率数据来看,乳化植物甾醇的作用效果优于普通植物甾醇。
[Abstract]:This experiment was conducted to study the normal and emulsified phytosterol on growth performance of fattening pig, serum biochemical indexes and nutrient digestibility. With 75 initial weight of about 60 kg Duroc pigs were randomly divided into 3 groups, the control group was fed basal diet, test group add 30 mg/kg phytosterol respectively based on in the diet (Group I) or emulsified phytosterol (Group II). The experiment lasted for 52 D.2 phytosterol had no significant effect on growth performance of fattening pigs, but significantly reduced the serum total cholesterol (TC), triglyceride (TG) level and globulin ratio (A/G) (P0.05), significantly increased serum total protein (TP) and globulin (GLO) level (P0.05), serum albumin (ALB) group was significantly lower than that of the control group (P0.05), and there was no significant difference between group II increased significantly; fattening on dry matter, organic matter, crude protein digestibility (P0.05), group II crude fat digestibility also was significantly higher than that in the According to the group (P0.05), the results showed that adding 30 mg/kg 2 phytosterols to the diet of finishing pigs can improve nutrient digestibility, regulate blood lipid and protein metabolism. From the data of serum ALB and crude fat digestibility, the effect of emulsified phytosterol is better than that of conventional phytosterols.
