Method for propagating chickens

Abstract

The invention belongs to the field of agricultural pasturage and propagation, and provides a method for propagating chickens. At the aim of production stage difference between slowly growing chickens and quickly growing chickens, young quickly growing chickens are firstly divided into several groups to bred in advance 10 days; 2.5 quickly growing chickens are bred in a henhouse with a volume of 8-10 slowing growing chickens per square meter; after the quickly growing chickens are put on the market, padding is cleared, the henhouse is disinfected, the slow growing chickens are transferred from the groups and bred in expanded groups, and the propagation of the slow growing chickens is into a normal propagating management stage of the quickly growing chickens. The method provided by the invention has the characteristics that the spread of diseases is reduced since the quickly growing chickens are divided into the groups and bred stage by stage; the growth potential of the quickly growing chicken are elaborated, the weight and feed conversion ratio obtain the optimal production performance; the weight and feed conversion ratio meet the homochronous level of individual breeding; and the breeding area of the henhouse is fully utilized, the production of unit area and the efficiency of the henhouse, devices and manpower are improved, and the propagating efficiency is increased.

Description

technical field [0001] The invention belongs to the field of animal husbandry, and relates to a chicken breeding method, in particular to a nested breeding method of fast chickens and slow chickens. Background technique [0002] Broiler chicken production in my country is divided into two systems: one is mainly fast and large broiler chickens, which have the characteristics of fast growth and high feed conversion rate. The feeding period is 40-60 days, and the market weight is 1.8-2.5 kg. Represented by Aiba Yijia broiler chicken, Aiweiyin broiler chicken, and Zhongbai chicken; the other is mainly high-quality chicken with local chicken blood that pursues delicious meat quality and complete color and taste. The breeding period is 90-120 days, and the market weight 1.2-1.8 kg, known as slow chicken, of which Jiangsu and its surrounding areas are represented by Xueshan grass chicken, Liyang yellow chicken, Langshan chicken and Xianju chicken. The brooding periods of fast chicke...

Problems solved by technology

Due to the small size of the chicks and the need for high brooding temperature (30~35°C), the chicks are often housed around the heat source during the production process, so the brooding area in the all-in-all-out feeding method (currently a common feeding method) for broilers Usually it only occupies 1/3~1/2 of the whole area of
