| 摘 要： | 为探讨乳酸菌在填饲过程中对朗德鹅产肝性能、脂肪沉积、屠体性能、养分表观消化率及血清生化指标的影响,试验选用108只健康、体重相近的12周龄朗德鹅,随机分为试验A组、试验B组和对照组,每组6个重复,每个重复6只。对照组填饲日粮为无乳酸菌菌液的基础日粮,试验A、B组于正式填饲前期(1~5 d)分别在基础日粮中添加2 000、3 000 g/t乳酸菌菌液;正式填饲中期(6~15 d)分别在基础日粮中添加3 000、5 000 g/t乳酸菌菌液;正式填饲后期(16~25 d)不添加乳酸菌菌液。结果表明,与对照组相比,日粮中添加乳酸菌使填饲朗德鹅肥肝成熟期延长(P<0.05),淘汰率降低;与对照组相比,日粮中添加乳酸菌使填饲朗德鹅肝脏脂肪沉积比例下降,试验B组肥肝重、肝脏重/(肠脂重+腹脂重)、肝脏重/填饲期增重显著降低(P<0.05);各组间屠体性能指标均无显著性变化(P>0.05);与对照组相比,试验B组粗脂肪表观消化率显著升高(P<0.05),试验A、B组钙、磷的表观消化率显著升高(P<0.05);与对照组相比,试验A、B组血清中甘油三酯、胆固醇和极低密度脂蛋白含量显著降低(P<0.05)。综上所述,饲喂添加乳酸菌的日粮虽可促进鹅体健康,但会延缓鹅肝脏脂肪的沉积,不利于鹅肥肝生产。因此,生产中不宜在朗德鹅填饲日粮中添加乳酸菌。

| Abstract: | In order to study the effect of lactic acid bacterium on liver performance, fat deposition, slaughter performance, nutrient apparent digestibility and serum biochemical indices of Landes geese, a total of 108 12-week-age healthy Landes geese were selected and randomly divided into 3 groups with 6 replicates per group and 6 geese per replicate.The geese in control group were fed with the diets without lactic acid bacterium during the whole experiment, and the geese in groups A and B were fed with the diets supplemented with 2 000 and 3 000 g/t lactic acid bacterium during 1 to 5 d, respectively;With 3 000 and 5 000 g/t during 6 to 15 d, respectively;And with no lactic acid bacterium during 16 to 25 d.The results showed that compared with the control group, supplementation of lactic acid bacterium could prolong the mature period of liver (P<0.05) and decrease the elimination rate of Landes geese.Compared with the control group, supplementation of lactic acid bacterium could decrease the rate of fat on liver, the average weight of liver, liver weight/weight of bowel and abdominal fat and liver weight/weight gain in group B were significantly decreased (P<0.05).There were no significant differences in slaughter performance among all groups (P>0.05).Compared with the control group, the apparent digestibility of crude fat in group B was significantly increased (P<0.05), the apparent digestibility of calcium and phosphorus in groups A and B were significantly increased (P<0.05).Compared with the control group, the serum content of triglyceride, cholesterol and very low density lipoprotein in groups A and B were significantly decreased (P<0.05).In conclusion, diets with lactic acid bacterium were good to geese, but considering its prevention of fat deposition in liver, lactic acid bacterium was suggested not to be used in force-feeding process. |
