Causes and control methods of depilation in laying hens

In the breeding of laying hens, there is often the phenomenon of depilation in the flock, which is mainly concentrated in the neck and back, some of which will lead to a decrease in egg production, while others will not affect it. So what is the reason for the depilation of layers? The following editor will give a big explanation.

1. Improper management

In the case of insufficient feed for laying hens, there will be hair pecking and depilation in the case of insufficient food, because the lack of adequate nutrition will be accompanied by a decline in the laying rate. In addition, when the water is cut off for a long time, the laying hens will also have serious stress depilation, which will also affect the egg production. When the laying hens are stimulated by the external environment, it will also lead to the decline of the laying rate and induce the phenomenon of hair change.

Prevention and control methods: feeding management must be proper, so that laying hens have enough to eat and drink, take in enough nutrition, reduce hair removal, and keep the henhouse quiet as far as possible to avoid stress caused by strangers or animals.

2. Lack of nutrition

The main performance is that the content of protein in feed is low, especially when there is a lack of sulfur-containing amino acids, it will affect the main component of feather keratin river crab, resulting in a large number of feathers of laying hens shedding, some can not grow after shedding.

Prevention and treatment: when laying hens depilate due to nutritional problems, it is necessary to adjust the content of protein in feed, increase the proportion of crude protein feed, and make it return to normal as soon as possible.

3. Environmental reasons

In summer when the high temperature is hot, and the chicken house cooling measures are not in place, laying hens in order to distribute body heat, there will be a small amount of hair removal phenomenon. In addition, frequent power outages or forgetting the light or changing the light time will lead to the decrease of egg laying rate and lead to depilation, especially during the transition in spring, when the light intensity suddenly increases, which is very easy to cause chicken stress, feather pecking phenomenon and depilation, and parasites can also cause layer depilation.

Prevention and control methods: in high temperature, we should do a good job of ventilation and light, reduce the temperature of the henhouse, and pay attention to the feeding density, so as to prevent layers from dissipating heat and pecking feathers. For the light time is fixed, the light time should not exceed 16 hours a day, at the same time, we should do a good job of deworming regularly to prevent parasites.

The above are the reasons for layer depilation and the introduction of prevention and control methods, hope to help you, want to know more related knowledge, please follow us.
