The weather is getting hotter and hotter, and there will be heat stress. The heat stress refers to a series of abnormal reactions of chickens in the high temperature environment due to the regulation of body temperature and physiology. Feed intake, production performance, feed conversion rate, etc., have different degrees of impact, and even chickens have heat shock and death. So how do you prevent heat stress?
Take effective measures to reduce the temperature of the house, you can plant trees in the vicinity of the house to reduce the amount of direct sunlight and heat radiation, spray cooling, this is a very effective cooling measures, spray water every 2 hours ~ 3 hours , can reduce the temperature of 4 ° C ~ 8 ° C. Strengthen ventilation and cool down. Install fans and exhaust fans in the chicken house, increase the air inlet and outlet of the chicken house, use longitudinal ventilation to blow the wind directly to the chicken body, or set a water curtain at the air inlet to allow the outside hot air to cool before entering Chicken coop.
Strengthen feeding management, reduce the adverse effects caused by heat stress, change the feeding time to avoid the hottest time, choose to feed in the morning, evening or night relatively cool time to help the chickens eat . Appropriate reduction of stocking density The chickens have a high density of feeding, heat production, and large heat dissipation, resulting in an increase in the temperature of the house, and high-density feeding will make the heat stress more serious.
Excluding harmful gases in the house due to high ambient temperature and increased drinking water, most chickens are diarrhea, and chicken feces in the house produce a large amount of ammonia gas and hydrogen sulfide gas, which aggravates the chicken heat stress response in chicken battery cages.
