Embodiment 1

[0020] A method for non-fasting forced moulting of laying hens, carried out according to the following steps:

[0021] The first step, molt preparation

[0022] Before moulting, the flock should be grouped, and sick chickens, weak chickens and chickens that have just moulted in the flock should be eliminated; one week before moulting, Newcastle disease immunization should be carried out once, and chickens raised on the ground should be immunized against Newcastle disease one week before moulting. , but also to deworm and kill chicken lice; weigh the individual weight of at least 30 chickens before the start of moulting, for measuring the weight loss rate of chickens during the moulting process and for reference;

[0023] The second step, the implementation of moulting

[0024] From the implementation period, feed the moulting feed composed of the following raw materials in proportions by weight: 50 parts of corn, 20 parts of rice bran, 25 parts of wheat bran, 3 parts of shell...

Abstract

The invention discloses a non-fasting forced molting method for laying hens, belongs to the technical field of forced molting methods for poultry in poultry raising, and provides a non-fasting forced molting method in order to find a feasible method for inducing molting of poultry instead of a starvation method. The method specifically includes the steps that hens are fed with molting feed in the molting implementation stage, the daily feed intake amount of each hen is controlled to range from 40 g to 55 g, the temperature of a henhouse is controlled to range from 18 DEG C to 25 DEG C, and the light illumination is controlled to be 8 h / d; the hens are fed with recovery stage feed and can eat feed freely in the molting recovery stage, the temperature is controlled to range from 20 DEG C to 27 DEG C, and the light illumination is 16 h / d. According to the method, stress on the hens is small, the death and culling rate of the hens is small, the method meets the animal ware requirement, meanwhile, the laying rate rises again very fast after the molted laying hens start to lay with the method, and the method is a laying scheme which is scientific in management, high in cost effectiveness and sustainable and can be widely applied.

Description

technical field [0001] The invention belongs to the technical field of poultry feeding, and in particular relates to a method for forced moulting of poultry. Background technique [0002] Under natural conditions, after about one year of laying time, especially after the summer, the hen consumes a lot of nutrients in the body, and its physical fitness declines. In autumn, production is often stopped due to moulting. After moulting, the feathers of the chickens will be plump and their physique will recover, which is conducive to overwintering. The process of natural moulting is very long, generally takes 3 to 4 months. Moreover, the degree of molt in the flock is very irregular, the egg production rate is relatively low, and the eggshell quality is also inconsistent. [0003] In practice, forced molting is performed in order to prolong the productive life of chickens. Forced moulting can also improve the quality of eggshells, reduce the breakage rate of eggs, and reduce th...
