Embodiment 1

[0028] A method of forced molt to improve the production performance of meat breed ducks. The total number of meat breed ducks is 5000, including 915 male ducks and 4085 female ducks. The specific method is as follows:

[0029] (1) Preparation before forced moulting: Eliminate all overweight, underweight and disabled breeding ducks 7 days before feed cut-off, so as to reduce the death rate during forced moulting and reduce economic losses. Renovate and strengthen the partitions in the house to prevent breeding ducks from crossing fences, overhaul drinking water facilities and lighting fixtures, and replace damaged light bulbs. Select the male ducks 3 days before the cut-off, place them in No. 9-10 pens and confirm the quantity, and evenly divide the female ducks into No. 1-8 pens and count the quantity. 1 day before the feed is cut off, remove all the feeding boxes and egg-laying boxes in the house, thoroughly clean the duck manure, duck feathers, dust and spider webs in the d...

Abstract

The invention discloses a forced moulting method for improving the production performance of meat breeding ducks, which solves the problems of high mortality rate, low fertilization rate and the like existing in the prior art. The method comprises the following steps: preparation before molt: eliminate unqualified breeding ducks, separate male and female; feeding period: stop feeding, take the initial body weight after 8 hours, calculate the weight loss rate by weighing every day on the 7th day and thereafter, supply water regularly, shorten Illumination time; Restoration feeding period: When the weight loss rate of male and female ducks reaches 15%, 28%-30% respectively, feed the finished feed, the amount of feed is different, water is supplied throughout the day, and the light is increased to 17h in the later period; mixed group: male-female ratio 1:4.6 ~4.8, time-limited feeding, change egg-laying feed after seeing eggs, feed freely when the egg-laying rate is above 20%, supply water throughout the day, and light for 17 hours; Immunization: Vaccines such as duck plague from the 2nd week to the 6th week after feeding. The invention is mainly used for the forced moulting of meat breeding ducks, so that the ducks can maintain a healthy physique, improve the quality of breeding eggs in the second laying period, and prolong the economic utilization period.

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...
