Heat stress and its mitigation measures in summer and autumn chickens
Effect of heat stress on broilers 1. Physiological and biochemical changes of broilers under heat stress. When the ambient temperature rises, the chicken body temperature will rise with the ambient temperature rise, at this time the heart rate will accelerate, blood pressure will decrease, breathing will accelerate wheezing, and respiratory intoxication will occur in severe cases. In addition, heat stress can also lead to endocrine disorder, adrenocorticosteroid concentration increased significantly in the early stage of heat stress, but gradually decreased thyroid hormone secretion, activity decreased resulting in reduced metabolic rate. 2. Heat stress on meat

The quality of water is the premise of raising marten well.
Mink farm to ensure the quality of water is the basis of raising marten. The quality standard of water is based on the metabolism of mink and the water content of products. 1 clean drinking water turbidity below 3, clear and transparent to the naked eye, free of impurities. If there are algae, sediment, fine matter will make the water turbid, not only increase the proportion, but also may make bacteria breed, produce toxic substances. Therefore, selective treatment measures should be used, or dregs can only be removed by boiling and filtering.
