Measures for raising firewood chickens in summer

The high temperature, heavy rain and humidity in summer is the season of frequent occurrence of firewood chicken epidemic disease. In order to keep the ecological free-range chicken from wilting "rest" in summer, farmers must carry out scientific stocking in order to obtain better economic benefits.

1. The working temperature of preventing heat and cooling is directly related to egg production. The ideal laying temperature of Chai chicken is 15 ℃ ~ 24 ℃, and the laying rate decreases gradually when the laying temperature is above 25 ℃. When the chicken is more than 30 ℃, the laying rate decreases significantly, or even stops laying, and a large number of deaths are likely to occur when the ambient temperature is above 35 ℃. Therefore, in order to keep Chai chicken laying more eggs in summer, measures must be taken to cool down and prevent heat, such as building awnings in stocking farms, ventilation and spraying walls in chicken sheds, and controlling the environment of chicken sheds and farms below 28 ℃.

Second, the amount of drinking water of Chai Chicken with adequate drinking water varies greatly with the change of ambient temperature. the amount of drinking water in summer is about 4 times that in winter and 3.5 times that of food intake, and chickens do not like to drink water with higher temperature. so in summer, we should pay attention to let the firewood chicken drink clean and hygienic cold water, preferably mountain spring water. Because the rise of water temperature requires a lot of heat, even if the ambient temperature rises greatly, the body temperature rises very slowly. At the same time, with the increase of water excreted by feces and urine, a large amount of body heat is taken away. When the external temperature is 32 ℃, a chicken can take away 4500 calories by drinking water 300ml a day. The cooling and heat prevention effect is very obvious, and the egg production rate of chicken intake is increased.

Third, adjust the nutrition environment temperature is high in summer, the heat energy needed to maintain the firewood chicken needs to be reduced, while the protein needs to be relatively increased. The effective way to keep the firewood chicken laying more eggs in summer is to use animal and vegetable fat instead of carbohydrates. 3% bean cake and 2% fish meal can be added to the feed, which changes the ratio of energy to protein accordingly, while paying attention to maintaining the balance of amino acids.

Fourth, adding anti-heat stress additives in hot summer, adding appropriate amount of anti-heat stress additives to the supplementary feed of Chai chicken is helpful to increase egg production, adding vitamin C in feed, electrolytic multidimensional, etc., and adding zinc chloride, ammonia chloride, sodium bicarbonate and aspirin in drinking water, and properly reducing the content of salt can effectively reduce the harm of heat stress and improve the egg production and quality of Chai chicken.

Chai chicken can also be fed with Chinese herbal medicine additive, which can not only prevent and cure some diseases, but also resist heat stress, and has obvious effect on improving chicken production performance. Such as heat-clearing and fire-lowering: plaster, gardenia, etc., can help the body to dissipate heat; heat-dispelling category: patchouli, Artemisia annua, can dissipate heat and prevent heatstroke; Anshen surprise: Polygala, cypress kernel, sour jujube kernel, can calm the mind and calm down shock, have the effect of anti-heat stress.

Fifth, strengthen stocking management to provide enough fresh and clean cold water throughout the day; reduce the feeding density as much as possible can effectively reduce the ambient temperature; pay attention to early release of chickens and late harvest of chickens, and try to avoid the hot time for firewood chickens to go to the wild to eat.

6. do a good job in the prevention and control of epidemic diseases. Summer is a period when the body of chickens is weak, so we should do a good job in disease prevention and control. Keep the chicken sterilized 2-3 times a week to keep the chicken house clean and hygienic. Strictly implement the immunization procedures, regularly monitor Newcastle disease antibodies, find abnormalities, and take corresponding measures in time. Regular spraying of pyrethroids and other insecticides harmless to humans and animals in chicken sheds and farms to completely eliminate mosquitoes, flies, Culicoides and other pests. Tamijing, gram ball powder and other drugs were regularly put into the supplementary feed to prevent chicken disease.
