Method for forced moulting of broiler breeders

A technology of forced moulting and broiler breeders, which is applied in the field of poultry farming, can solve problems such as not recommending moulting work, affecting the feed intake speed of chicken flocks, and decreasing egg production rate, so as to increase the cumulative amount of qualified breeding eggs, increase The survival rate of chickens and the effect of preventing late infection

[0006] 3. There is also a method of feeding Chinese herbal medicines to the chickens during the feed reduction period, but the cost is relatively high
[0009] Temperature and humidity: The temperature of the chicken house is controlled between 16-30°C. In Chongqing and Sichuan, due to the high humidity all year round, ventilation management is very difficult, and the chicken group feels that the temperature is difficult to drop, so it is particularly easy to cause moulting failure. - It is not recommended to carry out moulting work between September (especially at this stage when the egg production peak is

Example Embodiment

[0039] Example 1

[0040] A method for forced moulting of broiler breeders, comprising the following steps, the total number of chickens being 100;

[0041] Step 1. Preparation for forced moulting: Feed drugs to prevent salpingitis two weeks before moulting, and then carry out drinking water immunization with new branch two and pass vaccine, and 10 days before moulting, do immunization against new flow and avian influenza virus H5 subtype II Inactivated vaccines RE-6 strain and RE-4 strain, the chicken house temperature is controlled between 16-30 ℃, and the humidity does not exceed 85%;

[0042] Step 2, flock adjustment: weighing the flocks treated in step 1, and eliminating chickens with poor physique and overweight at the same time, and the weight uniformity of the flocks in each building reaches 91%;

[0043] Step 3. Feed reduction control: According to the normal feed amount, reduce feed by 20g per chicken per day, and drink water normally. Adjust the light time to 10h o...

Abstract

The invention discloses a method for forced moulting of broiler breeders. The method comprises the following steps: preparing forced moulting: making immune preparation, adjusting the temperature of a chicken house and the like before moulting; adjusting flocks: performing weighing treatment on chicken flocks, meanwhile, eliminating chickens with poor physique and overweight, and enabling body weight uniformity of each chicken flock to reach 90 percent or above; performing feed reduction control: performing feed reduction treatment on the basis of normal feed dose, and controlling drinking, illumination intensity and illumination time; recovering a feeding stage; performing management on egg-laying maturity, peak season and laying later-stage. By means of scientific and rigorous preparation steps of controlling the preparation before the forced moulting, adjusting the flocks, performing feed reduction control, recovering the feeding, performing later-stage management and the like, the death rate of the chickens during moulting is reduced, the egg-laying rate of a second egg laying period is effectively enabled to recover to ideal conditions, the descending speed of the later-stage egg-laying rate is retarded, and the quantity of accumulated qualified breeding eggs is improved.

Description

technical field [0001] The invention relates to the field of poultry breeding, in particular to a method for forced moulting of broiler breeders. Background technique [0002] At present, the so-called artificial forced moulting is to artificially apply some emergency factors to chickens to stop laying eggs, lose weight, shed feathers and replace new feathers. It is one of the important feeding and management techniques to prolong the effective use period of breeder chickens by rationally using breeder chickens and implementing artificial forced molt. [0003] The current methods are as follows: [0004] 1. The starvation method at the beginning: by cutting off water, food, and light, artificially exert stress factors on the chickens, disrupt the normal life of the chickens, cause sudden physiological stress to the chickens, and cause hormone secretion to lose balance. Decline, and promote the reduction of estrogen in the ovary, resulting in follicle atrophy, causing stop ...
