菊苣残渣生物饲料添加剂在蛋鸡生产中的应用

目的]研制1种新型的生物饲料添加剂,并探讨其对蛋鸡养殖的实际功效。方法]选用枯草芽孢杆菌、嗜酸乳杆菌、保加利亚乳杆菌、地衣芽孢杆菌作为试验菌株,以菊苣残渣为发酵原料,研制1种新型的生物饲料添加剂,并探讨其对蛋鸡生产性能和鸡蛋品质的影响。结果]在饲料中添加新型的生物饲料添加剂后,蛋鸡产蛋率提高2.3%,料蛋比降低13.9%,平均蛋重提高1.4%,蛋黄黄度明显提高15.5%。当该新型的生物饲料添加剂的添加量为1%时,蛋黄的粗蛋白含量也有显著提高。结论]用菊苣研制成的新型生物饲料添加剂可用于蛋鸡生产中。

Application of Chicory Residue as a New Type of Biological Feed Additive in the Production of Laying Hens

Objective] The purpose of the research was to-develop a new type of biological feed additive and discuss its actual efficiency on the culture of laying hens. Method] Bacillus subtilis, Lactobacillus acidophilus, Lactobacillus delbrueckii and Bacillus licheniformis were used as test strains and chicory residue was used as fermentation material to develop a new type of biological feed additive. And its effects on the production performance of laying hens and egg quality were studied. Result ] After adding new type of biological feed additive in the feed, the egg production rate increased 2.3%, feed-egg ratio decreased 13.9%, average egg weight increased by 1.4%, the egg yolk yellow signifi- cantly improved 15.5%. Conclusion] The new type of biological feed additive produced with chicory residue could be used in the production of laying hens.
