Changes of physiological habits of laying hens

The physiological habits of laying hens will change seasonally, and experienced farmers have already mastered this rule, and their breeding and management are more scientific, so the egg production is relatively stable in different seasons. If you do not understand this law, the egg production of laying hens will fluctuate obviously at the turn of seasons. Below, the pro-agricultural network will tell you about this law, hoping to bring some help to laying hen farmers.

I. the changing law of feeding habits.

Both adult laying hens and breeder hens have obvious responses to the seasons in terms of their feeding habits, especially in winter and summer.

1. The feed intake decreased significantly in summer.

When the temperature is high in summer, the energy demand of laying hens will be reduced, and so will the feed intake. As a result of the reduction in food intake, the intake of protein and calcium is also reduced, resulting in a decline in egg production. Generally speaking, as long as the temperature exceeds 30 ℃, the feed intake will be reduced by 10% to 15%. In case of high temperature and extreme heat, the feed intake will be reduced by 30%. The diet should be adjusted appropriately at this time. And take various measures to reduce the temperature of the chicken house.

two。 A marked increase in feed intake in winter

The temperature is low in winter, and laying hens need a lot of nutrition to protect themselves from the cold weather. When the temperature was lower than 22 ℃, the feed intake of chickens increased by 1.3 to 1.5 grams for every 1 ℃ decrease. At this time, it is necessary to increase the temperature of the chicken house on the premise of ensuring the air quality of the chicken house, and convert the diet into a winter diet, that is, to provide more energy feed to resist the effects of low temperature.

Second, the change law of drinking water

In addition to changes in diet, drinking water also changes throughout the year, mainly highlighting the increase in the amount of water consumed in summer, usually 2 times the weight of feed for laying hens in lukewarm climates and 4-5 times the weight of feed under hot conditions.

If the layers are short of water, it will lead to a decrease in egg production, and it is very obvious. For example, lack of water for 24 hours can reduce egg production by 30%. Therefore, we must ensure that laying hens have adequate water consumption, but at the same time, we should pay attention to the situation that laying hens may leak if they are supplied with drinking water without restraint.

Third, the change of feathering habit

Under the condition of natural light, it takes 3 to 4 months for adult chickens to molt naturally in autumn. Therefore, we should pay attention to the changes of light time and chicken house temperature, keep warm and supplement light in time. To ensure the production performance of laying hens.

These are the laws of changes in the physiological habits of laying hens introduced by the pro-agricultural network. If we master these laws, the breeding of laying hens will be more in place, and the laying rate will be stable.
