摘要
随着蛋鸡遗传育种的进展及饲养规模化、现代化和集约化发展,鸡群对生活环境条件和饲养营养的要求越来越高,生产成绩和养殖效益也逐步提高。但是在实际生产中,由于品种、管理、疾病等各种情况,都会对规模化蛋鸡场的经济效益产生明显影响,不仅促使蛋鸡生长发育不良、饲料转化率降低,且还会造成产蛋率下降,甚至死亡率增加等,进而给蛋鸡养殖场的经济效益带来巨大损失。该文主要论述规模蛋鸡场养殖效益影响因素。
With the development of genetic breeding and the development of large-scale,modern and intensive feeding,the requirement of living environment and feeding nutrition for chickens is higher and higher.However,in actual production,due to the variety,management,disease and other conditions,it will have a significant impact on the economic benefits of large-scale hen farms,not only resulting in poor growth and development of layers,feed conversion rate reduction,moreover,it will cause the egg production rate to drop,even the mortality rate to increase and so on,thus brings the huge loss to the egg chicken farm’s economic benefit.This paper mainly discusses the factors affecting the breeding benefit of large-scale layer farm.
