摘　　要：试验旨在研究产胆盐水解酶植物乳杆菌对樱桃谷肉鸭生长性能、血浆生化指标、屠宰性能与肌肉品质的影响。选取540只1日龄樱桃谷肉鸭,随机分为3组,1个对照组和2个试验组,每组6个重复,每个重复30只。各组均饲喂基础日粮,2个试验组在饮水中分别添加无胆盐水解酶植物乳杆菌和产胆盐水解酶植物乳杆菌,活菌数含量均为10^(6)cfu/mL,试验期为42 d。结果显示:无胆盐水解酶植物乳杆菌组1~42日龄日增重、出栏重与成活率均显著低于其余两组(P<0.05),而产胆盐水解酶植物乳杆菌未对肉鸭生长性能产生显著影响(P>0.05)。产胆盐水解酶植物乳杆菌组肉鸭21日龄血浆甘油三酯、总胆固醇,高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)以及游离脂肪酸水平均为最低,其中甘油三酯、总胆固醇与游离脂肪酸水平显著低于无胆盐水解酶植物乳杆菌组(P<0.05),同时HDL-C水平显著低于其余两组(P<0.05)。两种植物乳杆菌对42日龄肉鸭血浆脂质水平与屠宰性能均未产生显著影响(P>0.05)。此外,两菌株可显著提高肉鸭屠宰后45min胸肌肌肉红度值(P<0.05),其中无胆盐水解酶植物乳杆菌可显著降低胸肌肌肉亮度值(P<0.05),显著提高pH_(45min)值(P<0.05);两菌株对屠宰后24h肉色或pH值均无显著影响(P>0.05),其中产胆盐水解酶植物乳杆菌较对照组可显著降低滴水损失(P<0.05)。研究结果提示产胆盐水解酶植物乳杆菌不会对樱桃谷肉鸭生长性能与屠宰性能产生不利影响,可降低21日龄血浆脂质水平,改善42日龄胸肌肌肉品质。The purpose of this experiment was to investigate the effect of bile salt hydrolase(BSH)-producedLactobacillus plantarum on Cherry Valley ducks in growth performance, plasma biochemical indexes, slaughter performanceand meat quality. A total of five hundred and forty one-day-age Cherry Valley ducks were randomized into 3 groups,including one control group and two experimental groups, with 6 replicates for each group and 30 ducks for each replicate.Each group was fed basal diet. The 106 cfu/mL of BSH-free or BSH-produced Lactobacillus plantarum was added intowater for the experimental groups, respectively. The experiment lasted for 42 days. The results showed that the averagedaily gain, final weight and survival rate during 1 to 42 days of age in the BSH-free Lactobacillus plantarum groupwere significantly lower than those in the other two groups(P<0.05). However, BSH-produced Lactobacillus plantarum hadno significant effect on the growth performance of the ducks(P>0.05). At day 21, the ducks in the BSH-producedLactobacillus plantarum group had the lowest levels of plasma triglyceride, total cholesterol, high density lipoproteincholesterol(HDL-C), low density lipoprotein cholesterol(LDL-C) and free fatty acid. Among the treatments, the triglyceride,total cholesterol and free fatty acid levels were significantly lower than those in the BSH-free Lactobacillus plantarum group(P<0.05), and the HDL-C level were significantly lower than that in the other two groups(P<0.05). The two typesof Lactobacillus plantarum had no significance on the plasma lipid level and slaughter performance of ducks at 42 daysof age(P>0.05). In addition, they significantly increase the redness value(P<0.05), and BSH-free Lactobacillus plantarum decreased the breast muscle lightness and raised the pH value of ducks for 45 min after slaughtering significantly(P<0.05). However, they had no significant effect on meat color or pH value for 24 h after slaughtering(P>0.05).BSH-produced Lactobacillus plantarum could obviously lower the drip loss compa
