Forced moulting method for improving meat breed duck production performances

Abstract

The invention discloses a forced moulting method for improving meat breed duck production performances, and solves the problems of high death and culling rate, low fertilization rate and the like in the prior art. The method includes the steps: preparation before moulting: eliminating unqualified breed ducks, and dividing male ducks and female ducks; feed stopping: stopping feed, weighing initialbody weight eight hours after, weighing weight in seventh days and every days after the seventh days, calculating weight loss rate, regularly supplying water, and shortening illumination time; feed supplying recover: feeding ducks with different quantity of feed when the weight loss rate of the male ducks and the female ducks reaches 15% and 28%-30%, supplying water in whole day, and increasing illumination to reach 17n hours in later period; mixing groups according to ration of the male ducks to the female ducks of 1:(4.6-4.8), feeding the ducks with the feed in a time limit manner, replacingfeed by egg laying feed after ducks lay eggs, freely eating when egg laying rate is 205 or more, supplying water in whole day, and performing illumination for 17 hours; immunization: injecting vaccines such as duck plague in second weeks to sixth weeks after feed is fed. The method is mainly used for forced moulting of meat breed ducks, healthy physique of the duck groups are kept, quality of eggs in the second egg producing period is improved, and economic utilization period is prolonged.

Description

technical field [0001] The invention belongs to the technical field of breeder duck breeding, and in particular relates to a method for forced molt of breeder ducks. Background technique [0002] Forced molting is a technique to prolong the laying time of breeding ducks. At present, the starvation method is mostly used in China, that is, stress is caused to breeding ducks by adjusting conditions such as feed, drinking water, and light. The traditional method is mixed feeding of male and female ducks, and the same feeding and management mode is implemented for both male and female ducks. The fasting body weight measured on the 2nd or 3rd day after the feeding is stopped is used as the initial body weight, and the feeding is resumed when the weight loss rate reaches 28% to 30%. The feeding amount is the same for male and female ducks. During the traditional method of moulting, the male duck’s anti-stress ability is worse than that of the female duck, and the death rate during...
