Description

A kind of breeding method of chicken

technical field

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

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 chickens and slow chickens are 0-3 weeks old and 0-6 weeks old respectively, which is the first stage in the feeding process. 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 for broilers (currently a common feeding method) Usually it only occupies 1/3~1/2 of the whole area of the chicken house, resulting in a waste of certain resources, such as empty circles, etc., and the farmers who raise slow chickens cause larger chicken houses than those who raise fast chickens in the brooding stage. Part of the area is free, and the utilization efficiency of chicken house area and equipment is relatively low. Nowadays, the chicken industry has entered a low-profit state. How to improve the efficiency of chicken houses, equipment and manpower has become an important technical link to increase the efficiency of farming.

Contents of the invention

The object of the present invention is to provide a method for raising chickens to improve the efficiency of breeding in view of the defects in the existing breeding methods.

The purpose of the present invention can be achieved through the following technical solutions:

A method of breeding chickens, including (1) fast chickens start brooding in separate pens in the same chicken house on the 11th day of slow chicken brooding. 10 days, separate breeding); (2) The fast chickens and slow chickens raised in separate pens are gradually expanded during the feeding process; (3) After the fast chickens are released from the slaughter, the bedding is cleaned, the chicken house is disinfected, and the After the new litter, the slow-moving chickens are transferred to groups and expanded to enter the normal slow-moving chicken feeding and management stage.

Wherein, the fast chicken has a breeding period of 40 to 60 days, preferably Arbor Yijia broiler, Aiweiyin broiler or medium white chicken; the slow chicken has a breeding period of 90 to 120 days, preferably snow mountain grass chicken , Liyang Yellow Chicken, Langshan Chicken or Xianju Chicken.

The thickness of the litter is 2-3cm, and the height of the fence is 35-40cm. The chicken house facilities are mainly small kettles and open food trays, generally 100/set.

During the breeding process, the ratio of slow chickens to fast chickens is 3.2~4:1, and 2.5 more fast chickens are raised per square meter of the chicken house. The suitable density of fast chickens during the feeding process: 25 chickens/m ² at 0~2 weeks old, 15~20 chickens/m ² at 3~4 weeks old, 10~12 chickens/m ² at 5~6 weeks old, 6 weeks old Up to 8 chickens/m ² for slaughter; the suitable density of slow-moving chickens during the feeding process: 30 chickens/m ² at the age of 0-2 weeks, 25 chickens/m ² at the age of 3-4 weeks, and 15-20 chickens at the age of 5-8 weeks /m ² , 10-15 birds/m ² at the age of 9-12 weeks, and 8-10 birds/m ² after the age of 12 weeks.

The chickens were immunized during the feeding process, and the chickens were disinfected before and after immunization. Vaccines were vaccinated according to the immunization procedures of slow-moving chickens and fast-moving chickens, and the slow-moving chickens were supplemented with Newcastle disease vaccine in the middle and late stages, and anti-stress drugs were used before and after immunization.

The antistress drug is baking soda, potassium carbonate or V _C .

Compared with prior art, the beneficial effect of the present invention is:

(1) Fast and slow chickens are reared separately to reduce the spread of disease.

(2) The feeding cycle of fast and slow chickens is different. Therefore, a batch of fast chickens are raised by using the free area in the early stage of slow chicken breeding, and the breeding area of the chicken house is fully utilized to increase the output per unit area and the cost of chicken houses, equipment and manpower. Efficiency, increase breeding benefits, raise 2.5 more fast chickens per square meter, increase income by 18.30% per chicken house (720 square meters of breeding area), and increase farmers' income.

(3) Giving up the largest area in the early stage to fast chickens can give full play to the growth potential of fast chickens, and the weight and feed-to-meat ratio can reach the best production performance. During the process, the body weight and feed-to-meat ratio reached the production level of single-breeding.

Detailed ways

The following examples are only for further elaboration on the content of the invention, and do not limit the protection scope of the present invention.

EXAMPLES In 2011, tests of fast chickens and slow chickens were carried out in cooperative farmers of Changzhou Lihua Livestock and Poultry Co., Ltd. 30 households were selected. The length of the chicken house is 60 meters, the width is 12 meters, and the breeding area is 720 square meters. Among them, 10 households raise snow-mountain grass chickens (slow-speed chickens) individually, and each household raises 6,500 chickens. 10 households raise medium-white chickens alone. Chickens (quick chickens), each household has 6,200 chickens, 10 households raise snow mountain grass chickens and medium white chickens, each household raises 6,500 snow mountain grass chickens, and 1,800 medium white chickens. The suitable density of white chickens during the feeding process: 25 chickens/m ² at the age of 0-2 weeks, 20 chickens/m ² at the age of 3-4 weeks, 10 chickens/m ² at the age of 5-6 weeks, and from the age of 6 weeks to slaughter (the 42 days) 8 birds/m ² ; the suitable density of grass chickens in the breeding process: 30 birds/m ² at the age of 0-2 weeks, 25 birds/m 2 at the age of 3-4 weeks, and 20 birds/m ² at the age of 5-8 weeks ² , 15 birds/m ² at the age of 9~12 weeks, and 9 birds/m ² at the age of 12 weeks. The medium-white chickens are raised with advanced seedlings, and after 10 days, the snow-mountain grass chickens are brooded in the free chicken coop. Carry out separate pen breeding, and the height of the fence is 35~40cm. After 42 days of age, after the medium-white chickens are slaughtered, the bedding is cleaned, the chicken house is disinfected, and new bedding is spread, the snow mountain grass chickens are transferred to the flock to expand the pen, and enter the normal snow mountain grass chicken feeding and management stage. The thickness of litter is 2~3cm. During the breeding process, the chickens were immunized, and the chickens were disinfected before and after immunization. They were vaccinated according to the immunization procedures of Zhongbai chickens and snow mountain grass chickens. The snow mountain grass chickens were 60 days old and received Newcastle disease vaccine. soda.

Table 1: Comparison of production performance and economic benefits of different feeding methods

It can be seen from Table 1 that the market rate of medium-white chickens raised in sets is 1.7% higher than that raised alone, and the weight of slaughtered chickens is increased by 0.18kg. There is no significant difference in production performance indicators such as market rate, feed-to-meat ratio, and slaughter weight of snow mountain grass chickens raised in nests compared to those raised alone. The income of each building is 13390 yuan for raising snow mountain grass chickens alone. The fast chickens and slow chickens of the present invention are raised together, and the income for each building is increased by 2450 yuan, an increase of 18.30%.
