Problems solved by technology

In order to improve the production efficiency of breeder chickens and make them produce more qualified eggs when the price of commercial chicks is high, breeder chicken farms must reasonably arrange the timing of brooding of breeder chickens. However, in actual production, due to the The scale of the generation farm is limited, and it is impossible for all breeders to catch up with the best timing for breeding

Embodiment 1

[0022] Specific operations for increasing production capacity of fast-type green-footed Ma chicken breeder hens:

[0023] (1) Eliminate sick, disabled and weak chickens, and keep healthy hens that are resting and laying eggs; 5% of the fixed-point chickens are weighed;

[0024] (2) Stop water, feed, and shading for 7 days; drink water on the 8th day, light intensity 5 lux, light time 8 hours (high temperature season, stop feeding, water shading, after 3 days, replenish water for 1 hour in the morning and afternoon every day, add light , light intensity 5 lux, light time 8 hours);

[0025] (3) Weigh the weight from the 6th day, and feed when the weight loss rate is 18%;

[0026] (4) Feed 50 grams per chicken per day on the first day of feeding, and then increase by 10 grams per day until 80% of the previous peak feed amount is maintained. The light intensity is 20 lux, and the light is added for 1 hour every day until 16 hours of light time. Waiting for start of production; ...

Embodiment 2

[0031] The specific operation of increasing the production capacity of medium-speed ephedra chicken breeder hens is as in Example 1.

[0032] The normal production performance of the above-mentioned medium-speed type ephedra chicken breeder hen is as follows: the body weight is 3400 grams when feeding is stopped for 60 weeks, the egg production rate is 55%, and the body weight is 2790 grams at the end. When the egg production rate is 10%, the weight is 3050 grams, the egg production peak is 78%, and the average egg production rate is 67% within 4 months of egg production.

[0033] After adopting the method of this embodiment, the production performance of the ephedra chicken breeder hen is compared with the normal production performance as follows: 60 breeding eggs were produced in the first 4 months of the implementation method, 80 breeding eggs were produced in 4 months after the implementation of the method, and 20 breeding eggs were produced more ×1 yuan / piece=20 yuan. 15...

Embodiment 3

[0035] The specific operations for improving the production capacity of high-quality Langya chicken breeder hens are as in Example 1.

[0036] The normal production performance of the above-mentioned high-quality Langya chicken breed hens is as follows: 1650 grams of body weight when feeding is stopped for 60 weeks, egg production rate of 55%, and body weight of 1350 grams at the end. When the egg production rate is 10, the weight is 1500 grams, the egg production peak is 78%, and the average egg production rate is 67% after 4 months of egg production.

[0037] After adopting the method of this embodiment, the production performance of the Langya chicken breed hens is compared with the normal production performance as follows: 60 breeding eggs were produced in the first 4 months of the implementation method, 80 breeding eggs were produced in 4 months after the implementation of the method, and 20 breeding eggs were produced more ×1 yuan / piece=20 yuan. The feed consumption was...

Abstract

The invention relates to the technical field of poultry breeding, and particularly discloses a method for improving high-quality breeding hen utilization efficiency. According to the method for improving the high-quality breeding hen utilization efficiency, healthy hens serve as objects. The method is characterized by including the steps: performing water stop, feed stop and shading on the hens for seven days, and performing drinking and illumination in the eighth days; adding feed when average weight loss ratio reaches 18%; adding 50g of feed for each hen in the first feed adding day, increasing 10g of feed in later each day, maintaining feed adding amount to not be changed until the feed amount is 80% in a previous peak period, increasing 1h of illumination time in each day, keeping invariant until illumination of 16 hours is achieved in the whole day, and waiting for laying; adding feed in each day in a balanced manner until the feed amount of the previous peak period is achieved, and stopping feed adding when the laying rate of the hens is increased; decreasing feed in time after the feed amount of the peak period is achieved. The steps of the method are simple, laying time isshort, the death rate of the breeding hens is low, operability is high, peak laying rate can reach 90% of that of a normal laying peak stage of the hens, more than four months are maintained, the utilization efficiency of the breeding hens is high, and economic benefits are high.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a method for improving the utilization efficiency of high-quality chicken breeders. Background technique [0002] High-quality chickens usually refer to Chinese local chicken breeds, or broiler chickens that contain blood from Chinese local chicken breeds. According to its growth and development speed, it can be divided into three types: fast and large, medium-speed and high-quality. Fast large-scale high-quality chickens can be marketed at 45-60 days old. They have high growth performance and production efficiency, and low production costs, but they are slightly deficient in meat quality, meat taste, and feather color, and their feet are slightly thicker. Medium-speed high-quality chickens are on the market at 60-90 days old. They have better body shape, appearance, feather color and meat quality. They are widely sold and moderately priced, meeting the requirements of ...
