Coping measures of cold stress in laying hens in winter

Coping measures of cold stress in laying hens in winter

Winter temperature changes, laying hens are prone to cold stress, so we should do a good job of cold insulation work, careful to prevent "cold stress". The optimum temperature for laying hens is 18~23℃. When the temperature is lower than 7℃, the body weight decreases, and when the temperature is lower than 4℃, the activity becomes dull, and the laying rate decreases obviously, or even production is stopped. Because the low temperature environment, the level of estrogen and progesterone decreased, affecting the production of eggs; At the same time, the thyroid activity of chickens is enhanced, so that the appetite, feed intake, digestive function is increased, and the economic benefits of feeders are reduced. Therefore, in low temperature, chickens need more energy to maintain and feed consumption increases, but the feed utilization rate decreases, which still cannot maintain the need for egg production, so that the body uses the internal reserves, resulting in weight loss, production level decline, population quality decline and feed conversion rate decrease.

Protective measures against respiratory diseases in chickens in autumn

Protective measures against respiratory diseases in chickens in autumn

Before the temperature drops, prepare the environmental control adjustment plan in advance, so that the chickens have time to adapt to the transition smoothly. The temperature difference between day and night is large, and the attention points are different between day and night. In the daytime, more attention is paid to the highest temperature, and the body temperature of the chickens is the core, while the attention is the minimum ventilation volume at night. Frequently turn the coop, especially after ventilation adjustment, ventilation volume and temperature should be balanced well, in addition to the ventilation system data matching, must go to the actual coop inspection, to see whether the small window into the wind is not symmetrical, blowing chicken, before and after the temperature difference is not big, coop sealing is not done, there is no place into the thief, there is not appropriate place to adjust in time.

Effects of vitamin A on animal husbandry

Effects of vitamin A on animal husbandry

Vitamin A is an essential vitamin for humans and animals, belonging to the fat soluble vitamin, it is known that vitamin A can maintain the normal vision of animals, and it also plays a very important role in maintaining animal body development, epithelial growth and differentiation, reproduction and bone development. In addition, vitamin A is an important member of the non-enzymatic antioxidant defense system. It is located in cell membranes and protects cell membranes by scavenging free radicals and peroxides, Avoid Lipid peroxidation by enzymatic or non-enzymatic reaction of polyunsaturated fatty acids (PU -- FA) under the action of free radicals and produce lipid peroxide (LP0). Palacios(1996) et al. proved that vitamin A was an effective antioxidant and free radical scavenger in vitro experiments. [1] Therefore, the role of vitamin A is particularly significant in animal husbandry.

Why is vitamin nutrition so important in late laying hens

Why is vitamin nutrition so important in late laying hens

The vitamin nutrition of laying hens in the late laying period is often ignored. According to the conventional thinking, the dietary nutrient concentration of laying hens in the late laying period should be appropriately reduced when preparing the late-laying materials. Many people have a misconception that the vitamin level will also be decreased when the nutrient concentration is reduced.
