粗酶制剂对小鹅生产性能、激素及生化指标的影响
Effects of Crude Enzyme Preparation Supplemented
24只7日龄健康雏鹅（川白×太湖），随机分成对照组和试验组，饲以大麦(占45 %)基础日粮，试验组按1 g/kg添加Biokyowa粗酶制剂。实验期为7~60日龄，每周称量体重，60日龄时经翅静脉采取血样，测定其中激素含量和生化指标。结果显示：（1）与对照相比较，三周龄以后，试验组体重显著增加(P<0.05)，在4~7周龄时的体増重显著高于对照(P<0.05)，采食量增加，料重比下降；（2）试验组的生长激素和IGF-I分别比对照组升高36.62 % (P<0.01)和66.55 % (P<0.01)，而β-内啡肽却低51.66 % (P<0.01)；（3）试验组TSH和T3水平较对照组高24.39 % (P<0.05)和16.81 % (P<0.05)，T4含量却低18.33 % (P<0.05)，T3/T4的比值升高；（4）与对照比较，试验组的胰岛素高36.75 % (P<0.01)，胰高血糖素低23.11 % (P<0.01)，胰岛素：胰高血糖素比值降低；（5）血浆中的谷丙转氨酶活性较对照组高4.46倍(P<0.01)，而尿酸浓度却下降57.50 % (P<0.01)。以上结果表明：酶制剂通过解除饲料中β-葡聚糖的抗营养作用，提高机体对对大麦的消化能力、改善碳水化合物的代谢和影响机体代谢激素水平，从而促进雏鹅的生长。
wenty four 7-day-old crossbred goslings (Chuan white×Tai lake) were divided randomly into control and treatment groups. Enzyme preparation was added in the diet of treatment group at dosage of 1 g/kg. The blood samples were collected from 60 day-old goslings via the wing vein. During the fifty-three days experiment, body weights were adopted measured each week, related hormone contents and biochemical parameters in plasma were determined. The results were as following:(1) Compared with control, body weight of treatment group were significantly higher (P<0.05) since 3-week-old goslings. The weight gains were significant higher (P<0.05) in 4~7 week-old goslings too, feed intake were increased and the “feed: body weight gain” was decreased; (2) Compared with control, growth hormone (GH) and insulin-like growth factor-I (IGF-I) levels were dramatically enhanced by 36.62 % (P<0.01) and 66.55 % (P<0.01) respectively, while the level of β-endorphin (β-END) decreased by 51.66 % (P<0.01); (3) Thyroid-stimulating hormone (TSH) and 3,3\
