植物源大蒜菌质活素粉对扬州鹅生产性能和激素分泌的影响

Effects of Botanical Activity Flour of Garlic Bacterium Substance on Performance and Hormonal Secretion of Yangzhou Geese

本研究旨在日粮中添加4种不同剂量植物源大蒜菌质活素粉(Botanical activity flour of garlic bacterium substance,GBS)研究其对扬州鹅生产性能和激素分泌的影响,为其开发利用提供理论依据和应用参考。选择1日龄扬州鹅240只,公母各半。随机分成5组:对照组使用基础日粮,试验1、2、3、4组分别在基础日粮中添加GBS0.25、0.50、1.00、2.00 g.kg-1配合料。结果表明:与对照组相比,总体1～60日龄,试验各组体增质量(BWG)分别提高5.91%(P<0.05)、8.18%(P<0.01)、13.64%(P<0.01)、13.64%(P<0.01);试验4组采食量(FI)提高8.79%(P<0.01);试验2、3组饲料转化率(FCR)分别降低7.55%(P<0.05)、9.37%(P<0.01)。试验2、4组胸肌粗蛋白质含量分别提高22.88%(P<0.05)、17.81%(P<0.05);试验各组胸肌粗脂肪含量分别降低22.82%(P<0.05)、31.21%(P<0.05)、44.63%(P<0.05)、33.22%(P<0.05)。试验3、4组T3水平分别提高11.76%(P<0.01)、14.38%(P<0.01);试验各组T4水平分别提高7.75%(P<0.01)、14.06%(P<0.01)、14.30%(P<0.01)、66.52%(P<0.01)。试验1、3、4组胰高血糖素(Glu)水平分别降低14.78%(P<0.01)、14.45%(P<0.01)、16.05%(P<0.01)。试验2、3、4组采食后3 h血清胰岛素(Ins)平均水平分别提高14.85%(P<0.01)、12.54%(P<0.01)、23.27%(P<0.01);试验1、3、4组血糖平均水平分别降低7.96%(P<0.01)、6.80%(P<0.01)、11.30%(P<0.01)。结果提示,扬州鹅日粮中添加一定剂量的GBS对其生产性能和激素分泌有促进作用,且在本试验的4个剂量中,以添加GBS 2.00 g.kg-1配合料组效果最佳。

In order to study the effects of Botanical activity flour of garlic bacterium substance（GBS） with four doses on performance and hormone secretion of Yangzhou geese,and provide theoretical basis and application consult for the development and utilization,240 one-day-old Yangzhou geese were allocated to five groups,including control group and trial group 1,2,3,4.The control group was fed with basical diets,each trial group was fed with basical diets added with 0.25,0.50,1.00,2.00 g·kg-1 GBS,respectively.The results showed that,compared with control group,the body weight gain of 1-60-day-old trial groups increased by 5.91%（P0.05）,8.18%（P0.01）,13.64%（P0.01）,13.64%（P0.01）;the feed intake in trial group 4 increased by 8.79%（P0.01）;the feed conversion ratio in trial group 2,3 decreased by 7.55%（P0.05）,9.37%（P0.01）.Crude protein of brisket in trial group 2,4 increased by 22.88%（P0.05）,17.81%（P0.05）;Crude fat of brisket in each trial group decreased by 22.82%（P0.05）,31.21%（P0.05）,44.63%（P0.05）,33.22%（P0.05）.Serum T3 in trial group 3,4 increased by 11.76%（P0.01）,14.38%（P0.01）;serum T4 in each trial group increased by 7.75%（P0.01）,14.06%（P0.01）,14.30%（P0.01）,66.52%（P0.01）;serum Glu in trial group 1,3,4 decreased by 14.78%（P0.01）,14.45%（P0.01）,16.05%（P0.01）.The average level of Ins after feeding in 3 h trial group 2,3,4 decreased by 14.85%（P0.01）,12.54%（P0.01）,23.27%（P0.01）;the average level of serum glucose in trial group 1,3,4 decreased by 7.96%（P0.01）,6.80%（P0.01）,11.30%（P0.01）.It had a encourage effect on performance and hormone secretion of Yangzhou geese by supplemented with GBS on their Goose die,and four doses in this trial,the effects of fed basical diets added with GBS 2.00 g·kg-1 is the best.
