Background
Forced moulting is a technology for prolonging the egg laying time of breeding ducks, and at present, a hunger method is mostly adopted in China, namely, the breeding ducks are stressed by regulating and controlling the conditions of feed, drinking water, illumination and the like. In the traditional method, male ducks and female ducks are fed in a mixed mode, the male ducks and the female ducks are fed in the same mode, the fasting weight measured at the 2 nd or 3 rd after feeding is taken as the initial weight, feeding is resumed when the weight loss rate reaches 28% -30%, and the feeding amount of the male ducks and the female ducks is consistent. In the traditional method, the stress resistance of the drakes is poorer than that of the female ducks in the moulting period, the death and culling rate of the drakes is far higher than that of the female ducks in the moulting period, the death and culling rate of the female ducks is about 2% generally, and the death and culling rate of the drakes is about 10%; the death and culling rate of female ducks during egg laying is at least 10 percent higher than that of male ducks. In addition, the traditional method has overlarge stress on meat breeding ducks, particularly on male ducks, and also causes the fertilization rate to be reduced after moulting, and the female ducks are easily damaged by the male ducks when the male ducks and the female ducks are fed in a mixed mode for moulting, so that the due egg yield can not be achieved, and the effect of forced moulting is greatly reduced.
Aiming at the problems, the invention adopts the separate feeding and molting of the male duck and the female duck, which explores the weight loss standard of the male duck and the female duck during the material changing, different feeding amounts and feeding methods after the material changing, different feeding management modes such as group mixing time and the like according to different physiological characteristics of the male duck and the female duck so as to obtain better economic benefit.

Detailed Description
Example 1:
a forced molting method for improving the production performance of meat ducks is characterized in that the total number of meat ducks is 5000, wherein 915 male ducks and 4085 female ducks are adopted, and the specific method comprises the following steps:
(1) preparing before forced moulting: the ducks with excessive weight, too small weight and the disabled are completely eliminated 7 days before feed interruption, so that the death and elimination rate during forced moulting is reduced, and the economic loss is reduced. And the partition fence in the house is repaired and reinforced to prevent duck stringing, overhaul drinking facilities and lighting lamps and replace damaged bulbs. Selecting male ducks 3d before material breaking, placing the male ducks in columns 9-10 and confirming the number of the male ducks, and uniformly dividing the female ducks into columns 1-8 and counting the number of the female ducks. And (3) moving the material box in the shed and the egg laying box all 1d before material breaking, thoroughly cleaning duck manure, duck feather, dust and spider nets in the duck shed and the sports field, and paving padding with the thickness of 5cm in the shed, wherein the padding is dry, loose and flat, and has no moisture, caking phenomena and sundries. Different kinds of disinfectant are used to completely disinfect the inside and outside of the house for at least 3 times. The duck shed is irradiated for 17 hours, the intensity is 20lx, the temperature is preferably controlled to be 18-21 ℃, the lowest temperature is not lower than 10 ℃ in winter, the highest temperature is not higher than 30 ℃ in summer, and the humidity is about 65%.
(2) A material stopping period: stopping feeding after preparing completely, adding Astragalus polysaccharides (70% of Astragalus polysaccharides as main ingredient) into drinking water while stopping feeding, and adding water 500kg per 100g for 3 days. And after stopping feeding for 8 hours, randomly drawing 10% of the weight of each column of 9-10 columns to be respectively weighed as the initial weight of the drakes, and randomly drawing 10% of the weight of each column of 1-8 columns to be respectively weighed as the initial weight of the female ducks. And 7d and later, respectively weighing 10% of male ducks and female ducks in the whole group every day and comparing the weight loss rate. The ducks in the fence are driven by the whole group when weighing, the breeding ducks are separated randomly by the separating net so as to avoid errors caused by uneven distribution of the big ducks and the small ducks, the ducks are weighed one by one, the error does not exceed 20g, and the weighing is timed, person-fixed and pound-fixed every time. During the material stopping period, water is supplied for 1 hour in the morning, in the middle of the day and at night, the water dispenser is scrubbed by disinfectant every day, and the internal and external environments of the house are disinfected 3-4 times every week. Stopping artificial auxiliary illumination, and adopting natural illumination or reducing the illumination time from 17h to 8h, wherein the illumination intensity is 20 lx.
(3) And (3) recovering the feeding period: the drake starts to feed the breeding material when the weight loss rate reaches 15% based on the initial weight, wherein the weight of each duck is 190g (twice feeding in the morning and afternoon) in the first week, 200g in the second week and 210g in the third week (the specific feeding amount is determined according to the weight increase condition, and the weight of each duck is more than 100g when the duck is mixed with the group). Taking the initial weight as a standard, the weight loss rate of female ducks reaches 28% -30% (generally about 15 days after the self-stopping date, if the death and culling rate exceeds 1%, feeding is performed in advance), feeding is started, 120g (60 g in the morning and 60g in the afternoon) of each female duck is added, 5g is added every day later, the second week is increased to 150g, 180g in the third week and 210-220 g in the fourth week, and the feed amount is maintained until the 4 th day after male and female ducks are mixed. The main nutrient value of the breeding material is as follows: 16.3 percent of digestible crude protein, 2740KC of poultry metabolism energy and 0.9 percent of calcium, and the breeding materials are uniformly and quickly scattered on padding so that all the breeding ducks can eat the breeding materials at the same time.
When the feeding is resumed, 100g of Shuanghuanglian (honeysuckle, scutellaria and forsythia as main components) is added into every 1000kg of drinking water for 3-5 days. During the feeding period, water is supplied all day long, the drinking trough is scrubbed by disinfectant every day, the natural illumination or illumination time is 8 hours before the end of the fourth week, from the fifth week, the illumination is increased by 1 hour every day until 17 hours, and the illumination intensity is 20 lx. The duck feather is cleaned in time, and the internal and external environments of the shed are disinfected 3-4 times every week.
(4) Group mixing: and (3) about 6 weeks after the female ducks stop feeding day, mixing the male ducks and the female ducks when the male ducks have uniform fresh feathers and the male ducks reach the initial weight which is more than 100g, uniformly dividing the male ducks and the female ducks into 1-10 columns according to the male-female ratio of 1: 4.6-4.8, and placing a feed box in the columns. From the 5 th after the mixed group, the feeding mode is changed from quantitative feeding to time-limited feeding, and the feeding time is 4 hours every day. Laying eggs for about 50 days after female ducks stop feeding, putting an egg laying box into a fence, changing the breeding feed into an egg laying feed, and prolonging the daily feeding time to 7 hours, wherein the egg laying feed can digest 19.5% of crude protein and can digest 2790KC and 3.1% of calcium. The egg laying rate can be more than 20%, the eggs can be freely taken 24h all day, the eggs after 2 weeks of egg production can be used for hatching, the egg laying rate can reach more than 50% in less than one week, and the egg laying rate in the egg laying peak period can reach 85% -90%. Supplying water all day long, scrubbing the drinking trough with disinfectant every day, and disinfecting the internal and external environments of the house 3-4 times per week. The illumination is kept for 17 hours, the illumination intensity is 20lx, and weak light is kept at night for the convenience of laying eggs, eating and drinking water of the breeding ducks at night.
(5) Immunization: determining an immunization program during forced moulting according to the antibody level, and in order to reduce the stress intensity and maintain the higher antibody level of the breeding ducks in the second laying period, immunizing the duck plague vaccine at the 2 nd week after the female ducks are fed again, 0.5 ml/duck, immunizing the avian influenza at the 3 rd week, 1 ml/duck, immunizing the flavivirus at the 4 th week, 1 ml/duck, immunizing the immunotoxic hepatitis at the 5 th week, 0.5 ml/duck, immunizing the special new bird dual of waterfowl at the 6 th week and 0.5 ml/duck. Before and after immunization of the vaccine, multivitamins are added into drinking water for 2 days to improve the anti-stress capability of the ducks, and the breeding ducks need to be lightly taken during immunization.
Test example 1:
selecting meat ducks in 3 duck houses, wherein the day age and the first egg laying period of the meat ducks are completely the same in feeding management mode, immunization program, facility equipment and the like, and the 3 duck houses are respectively subjected to forced moulting, natural moulting and direct brooding and egg laying without moulting for comparison, and the comparison results are shown in table 1.
TABLE 1 comparison of the three molting modes
The results show that: the forced moulting of the invention not only obviously shortens the period of non-parturition and prolongs the egg laying time, but also avoids the high cost of re-purchasing the breeding ducks and brooding and growing periods, and can save a large amount of cost.
Test example 2:
6000 meat ducks of 75 weeks old in the same duck shed are selected to be evenly divided into a control group and an experimental group, each group comprises 3000 meat ducks, and the conditions and modes of the two groups of male ducks and female ducks in the earlier stage are completely the same as those of the two groups of male ducks and female ducks in the earlier stage of feeding management, preparation work before moulting, environmental equipment, feeding management in the second egg laying period and the like (the same as the example 1), and data comparison is carried out until the egg laying period is finished:
control group: and (3) feeding the male and female in a male-female ratio of 1:5, taking the fasting weight measured in the 2 nd day after feeding stoppage as the initial weight, recovering feeding when the weight loss rate reaches 28-30%, feeding male and female ducks in consistent amount, feeding 120g of male and female ducks in the first day, increasing 5g of male and female ducks in each day, increasing 210-220 g of male and female ducks in the fourth day, and maintaining the amount of male and female ducks until the 7 th week after the feeding stoppage.
Experimental groups: feeding male ducks and female ducks separately, taking the weights of the male ducks and female ducks after stopping feeding for 8 hours as the initial weights of the male ducks and female ducks, recovering the feeding when the weight loss rate of the male ducks reaches 15%, feeding 190g of the male ducks every day in the first week, feeding 200g of the male ducks in the second week and feeding 210g of the male ducks in the third week; the feeding recovery mode of the female ducks is the same as that of the control group; the ratio of the male to the female is 1: 4.6-4.8 when all the new feathers are in a uniform mixed group.
The results of two sets of experimental data are as follows:
TABLE 2 comparison of meat duck performance between control and experimental groups
The experimental result shows that compared with the prior art of male and female mixed feeding, the method adopted by the invention can reduce the death and culling rate of meat ducks in the moulting period by 43.59%, the death and culling rate of the second laying period after moulting is reduced by 33.17%, the number of qualified eggs laid by female ducks in houses is increased by 6.45%, the average fertilization rate in the whole period after moulting is improved by 8.11%, and the number of qualified fertilized eggs is increased by 15.15%, thus the method has obvious advantages compared with the traditional method.
