The reason for laying rate decline when the weather is cold
Winter is coming, and the weather is getting cold. In this season, the egg production rate is low, and the eggshell quality is bad. Since the winter, the laying rate of laying hens has decreased. Various methods have been used. At first, it will have a little effect, but the slow egg production rate will drop.
So, what is the reason for the laying rate decline and poor eggshell quality? The following is the most common problems that caused the decline in egg production in winter and shared with you:
1. lack of nutrients
In the cold winter weather, in order to maintain the body temperature, the metabolism of the hens is accelerated, the energy demand will increase significantly, and the loss of protein feed will be increased. If the nutrient concentration in the feed is low or the normal physiological needs of the hens are not met, Will cause drop in egg production. In addition, insufficient supply of calcium, phosphorus and vitamins in the feed can also cause problems in the quality of the eggshell.
2. Stress factors
Due to weather changes, temperature drops, feed changes, power outages, water cuts and other external stimuli, it will cause the laying down of laying hens. In this season, pay special attention to the cold stress caused by the sudden drop in temperature.
3. Mycotoxin poisoning
New corn harvest season coincides with the continuous rainy weather. The corn is moisture and extremely susceptible to mold and mildew, which makes the mycotoxin content high. After the large number of new corn is marketed, the majority of breeding friends use the corn to feed, causing chronic poisoning of the egg mycotoxin, causing liver lesions, follicular necrosis, etc., resulting in decreased egg production.
4. Fatty liver
Fatty liver is a topic that everyone knows in poultry farming, and the occurrence of fatty liver in chickens mainly occurs in laying hens, which has a lot to do with the feeding period of laying hens. Whether it is broiler or laying hen, in order to maintain its high yield and stable yield, it is inevitable that the nutrition in the feed is comprehensive, and because of the long feeding period of the laying hen, the fat accumulates in the liver and forms fatty liver. Excessive fat in the liver can hinder the absorption of nutrients, resulting in poor absorption of nutrients, resulting in poor eggshell quality and reduced egg production.
Measures to prevent fatty liver and increase egg laying rate
1. Improve the nutrient concentration in the feed, increase the calcium, phosphorus, vitamins, protein and energy as appropriate to ensure that the nutritional needs of the laying hen.
2, Pay attention to the chicken house to keep warm, to avoid the temperature drop caused adversely affect the laying hen.
3. Regularly adjust the liver of the laying hen. The quality of the liver determines the number of eggs: the liver is an important organ for the formation of yolk, which is responsible for transporting the raw materials to the ovaries and follicles to synthesize the yolk. Therefore, the health of the liver directly determines the number of eggs produced.
Excessive accumulation of fat and toxins in the liver can cause a great load on the liver and affect the laying quality of laying hens. Therefore, the liver should be use endogenous bile acids to remove liver toxins and protect liver health to ensure egg production.
