Breeders are forced to moult, and what is controlled by the moulting of chickens

Autumn moulting of hens is a normal physiological phenomenon to renew their feathers and defend against winter cold. However, if it is allowed to moult naturally, the time is inconsistent, the moulting is slow, and the time is long (about 4 months), most chickens have to reduce or stop production during the moulting period, and the peak of egg production after moulting is also slow, which affects the egg production rate. Forced moulting is the artificial change of external environmental conditions to moult the flock in a short period of time.

The implementation of artificial forced moulting can not only shorten the moulting time (only 50 60 days), but also after moulting, the hen lays eggs more neatly, the egg production is more, the quality of the eggs is good, and the service life is long. At the same time, forced moulting is also convenient for feeding management and saving feed, reducing the number of brooding, reducing costs, and improving economic benefits. At present, artificial forced moulting has become one of the important technical measures for high yield of laying hens, and has been widely promoted and applied in production.

Artificial forced moulting, that is, the use of compulsory methods to moult chickens, in order to shorten the rest period of natural moulting, improve productivity. This technology can also be used to solve the spear of the breeder during the peak egg production period and the chicks in the off-season.

shield, improve economic efficiency.

Naturally, after about 1 year of egg laying time, especially after the summer, the nutrient consumption is very large, the physique declines, and the moult is often stopped in the autumn. After moulting, the feathers are plump and the physique is also obtained.

to recover, conducive to winter. Natural moulting takes a long time, generally taking 3-4 months. Due to the fast moulting of high-yielding chickens and the slow moulting of low-yielding chickens, the degree of moulting of the flock is not neat, which affects the quality of egg laying and eggshells, and is not economical.

Therefore, in the production of chickens, starvation, feeding chemicals or injection of hormones and other methods are often used to implement artificial forced moulting (the moulting time is generally not more than 1 month).

Forced moulting can reduce the cost of finishing chickens and save serving; It can improve the quality of the eggshell and the quality of the egg. Generally, in the late stage of egg laying, the proportion of soft eggs and broken eggs increases, and the rate of soft eggs and broken eggs can be greatly reduced through forced moulting, and the quality of eggshells is improved, which increases the value of commercial eggs.

Artificial forced moulting is mainly used for commercial laying hens, breeders (especially breeders with low egg laying rate) are generally not suitable for forced moulting. In addition, during the forced moulting period, the case fatality rate of the flock will increase.

Don't be those chickens that are hidden and don't show obvious. Therefore, flocks involved in forced moulting must be in good health and have high egg production performance.

Under natural conditions, the hen begins to moult in the autumn of the following year after about a year of egg laying. The natural moulting process is very long, generally 3 to 4 months, and the moulting in the flock is very uneven, the egg production rate is low, and the eggshell quality is also inconsistent. In order to shorten the moulting time and prolong the production and utilization life of chickens, artificial forced moulting is often adopted for chickens.

It is to make the whole flock stop production, moult, and recover physique in a short period of time, and then resume egg production, improve the quality of eggs, and prolong the economic utilization period of chickens.

Summary. Hello dear, controlled by the season. Chickens generally do not automatically change their feathers, he generally, if there is a situation where the membrane falls off, it will grow back in the later stage, and the time of falling off in the case of rotation is in autumn and winter.

Hello slippery dear, controlled by the season. Chickens generally do not automatically change their feathers, he generally, if there is a situation of bringing the film to shout and fall off, it will grow back in the later stage, and the time of falling off in the case of turning around is in the autumn and winter.

Forced moulting is a more commonly used management method in laying hen breeding, the purpose of which is to improve the production capacity of laying hens and extend the service life of laying hens. The forced moulting method of laying hens includes starvation method, high zinc diet method, hormone method, etc., among which the starvation method is the most common. Layer hens strong poor moulting preparation 1

The moulting season is controlled, first of all, to choose the right time for laying hens to moult and erect, generally choose in late summer or early autumn (or after the laying hens in an egg-laying cycle), in the laying hens just appear natural moulting begins. It is not advisable to carry out forced moulting of the flock in the hot summer and cold winter, as the heat and cold will affect the normal moulting work.

2.Adjustment and screening of the flock before the forced moulting work, the flock is adjusted and screened, this link is very important, it will affect the survival rate of the flock (forced moulting, for the laying hens to know that it is a strong stress, in order to increase the mortality rate. ), and production capacity.

And when the pie is over, the chickens that are too fat, too thin, sick, defective, and have a low egg production rate are eliminated, and the chickens that have been moulted should also be selected. 3.Enhance disease resistance Forced moulting is very stressful to laying hens, resulting in a decrease in chicken autoimmunity, weak disease resistance, and susceptibility to bacteria or viruses, resulting in a large area.

In order to enhance the immunity of laying hens during the forced moulting period and improve the ability to resist disease, vaccines such as Newcastle disease can be carried out before the forced moulting for 3 weeks to 4 weeks, deworming once 10 days before moulting, and using a course of antibacterial drugs.

4.Measure the average weight of the middle flock of chickens, randomly select 10% of the chickens in the herd to measure the weight, and take the average weight as the standard weight of the chickens. Methods and steps 1

Control food and water to empty the feed in the trough, stop feeding for 7-10 days (the specific stop time can be adjusted according to the health status of the chicken flock, the mortality rate of the chickens, and the weight change, with the average weight of the flock reduced by 25%-30%, and the total mortality rate should not exceed 3%. ）。In order to maintain the quality of the eggshell, the shell can be fed with shell pieces, and the amount of 20g per chicken can be added during the fasting period of Amin Mountain.

Stop drinking water for 2 days and drink freely.

2.Control the light 21 days before the forced moulting, the light is suddenly reduced to 8 hours, and after the resumption of feeding, gradually increase the light for 1-2 hours per week until the light reaches 15-16 hours a day. 3.

After fasting, each chicken was fed an average of 18 g of 18 g of crude protein laying diets on the first day, and then increased by 18 g per day until it was increased to ad libitum feeding.

Summary. Breeding roosters are not suitable for moulting.

Breeding roosters are not suitable for moulting.

The moulting of breeding roosters can affect the fertilization rate, the rooster has poor tolerance, and the mortality rate is high.

1. Before moulting, it is best to pick the whole group of chickens, and pick out the weak and sick chickens for elimination or sales, because this part of the breeders will also die in the process of moulting oak. 2. It is best to choose spring or autumn for moulting, and moderate weather is more conducive to successful moulting. 3. 7 days before moulting, you can add 5 grams of chicken gravel to the feed to increase the calcium storage in the long bones, or add CAHPO4 (1%) to the feed for three days before starting moulting.

4. Because the time of rooster and hen moulting is inconsistent, so the moulting of roosters and hens are raised separately, which is conducive to better male and female moulting and the success rate of moulting. 5. The chicken coop is all blackened, and the large board, small window and fan (fan shading cover is required) are easy to leak light, and the light leakage is easy to cause some chickens to moult unevenly, and start production in advance, resulting in premature birth.

6. On the morning of the water cut-off, proportional sampling and weighing should be carried out to record the initial weight. In order to facilitate the calculation of the weight loss rate of the flock during moulting.

7. During the moulting process, the first three days can be cut off at the same time to dismantle the material, and then the light is limited to feed, and 1-2 hours of light and drinking water are given every day, which is conducive to faster emaciation of the chickens. The moulting dates are weighed at the end of the first week and the second weekend. After the second week, it is best to weigh every 3 days, and monitor the weightlessness in time to avoid excessive weightlessness and an increase in deadness.

Generally, the weight loss rate of moulting is between 25% and 35%, and I personally think that the chicken flock can lose weight to the weight of the normal egg laying and fiber period, of course, it is also necessary to consider the problem of death rate.

8. After moulting to the 10th day, it is necessary to observe the condition of the flock, and the chickens that lose weight too quickly can be picked out and fed separately for a few days, and then put back to the large flock to continue moulting after recovering physical strength. 9, decided to stop starvation after the resumption of feeding, you can start to give the peak of the feed to do half of the amount of feed, the use of breeding feed, the first week can take a daily limit, the second week to begin to gradually increase the amount of feed every week, you can take 2 5 feeding method for feeding, that is, 7 days of feed 5 days to feed, a week on Wednesday and Friday to limit feeding is not fed, is conducive to the improvement of the uniformity of the flock. After resuming feeding, due to the poor state of the flock, the height of the water line should be lower than the normal level, so that the flock can drink better water.

10. The light is restored to 8 hours of light until the due date. Before adding light, it is necessary to evaluate the flock, according to the feather change of the flock, the recovery of the breast shape, the uniformity of the comb, etc. 11. From the second week of resumption of feeding, you can do normal vaccine for prevention.

12. Generally the 7th week of moulting can be carried out male and female mixing, the 8th week can be given 12 hours of light, 14 hours of light can be given when the egg laying rate is 1%, and 16 hours of light can be given when the egg laying rate is 35%.

In addition, as long as it is a rooster, it is not recommended to moult, which will affect the fertilization rate.

<> the forced moulting of laying hens needs to be picked out by the sedan chair with a light weight, which can reduce the risk of moulting. 2% zinc sulfate was added to the feed of the selected laying hens to increase the zinc content in the feed, and they were continuously fed for about 7 days; On the 8th day or so, it will be changed back to the original feed feeding, and about the 10th day, the laying hens will begin to stop production; It is not until around the 21st day that the eggs are laid again, i.e. the moult is complete.
