Environmental stress in pigs
Stress is the sum of the nonspecific responses of an organism to various unusual stimuli. Environmental factors that can cause stress response are called stressors or stress factors. Pigs are stimulated by environmental factors, but the form of reaction is different, general stimulation causes specific reaction of the body, such as cold in winter, pigs gather together; hot in summer, evacuation and other phenomena. Some stimuli (stressors) not only cause specific reactions, but also cause non-specific reactions, namely stress reactions, which are manifested as follows:

Factors causing stress in Pigs and Preventive measures
Pig stress is an inevitable problem in the process of pig production, the harm caused by stress is not only single, but also comprehensive, and its effects are various. If we can properly take various preventive measures according to different specific conditions, the losses caused by stress will be greatly reduced. Stress is the sum of non-specific responses of organisms to various very stimuli, and general stimuli cause specific responses of organisms. Some stimuli not only make the body produce specific response, but also cause non-specificity.

Heat stress and its control in pigs in summer
Heat stress refers to the sum of non-specific physiological responses of the body to any requirements put forward by the thermal environment in an extremely high ambient temperature. With the rapid development of intensive and high-density feeding, most southern regions are becoming more and more urgent to alleviate the environmental pressure caused by high temperature in summer on the pig industry, and the climate in the north also has an increasing trend. In recent years, the highest temperature in Beijing has also reached more than 40 degrees. The decline of pig productivity caused by heat stress has attracted more and more attention of livestock environment and feed nutrition researchers. Japanese, American, British and other Chinese studies

Common causes of stress in chickens
In chicken production, especially under the condition of intensive production, the chicken body has a certain adaptability and adaptability to the stimulation of feeding density, climate, immunization, transfer, grouping, capture, beak breaking, light and other factors. If the intensity of these stimuli is too large or lasts too long, which exceeds the physiological tolerance of the body, it will affect the growth, development, reproduction and disease resistance of chickens, and even directly cause death. The main factors that cause chicken stress are as follows. First, physiological stress. The high-yield chickens raised on a large scale are all caged.

How to manage cotton after topping in July
Heat or high temperature and humidity is one of the most harmful factors in the breeding industry, which will lead to the occurrence of heat stress syndrome in livestock and poultry. Heat stress suppresses the immune function of the body, reduces the concentration of immunoglobulin in blood and the number of lymphocytes in blood, resulting in the decrease of phagocytosis of macrophages in the body and infectious diseases of livestock and poultry. Therefore, heat stress will make livestock and poultry prone to all diseases. As the higher the production performance of modern excellent livestock and poultry breeds, the worse the ability to resist heat stress, serious heat stress often causes the livestock and poultry with high performance to die first, resulting in serious economic losses. Improve the performance of livestock and poultry

How to deal with sow heat stress in summer? What kind of injection should I get?
Pigs are thermostatic animals with thick subcutaneous fat, underdeveloped sweat glands and slow heat dissipation, so pigs are not heat-resistant. Heat stress in summer is easy to affect the fecundity of sows, so how to deal with it? What kind of injection should I give if there is heat stress? There's only one.

Why do fish frequently get sick?
In aquaculture practice, there is often a phenomenon that varieties with strong disease resistance in the wild become susceptible to diseases because they live in the aquaculture environment for a long time. The disease resistance of fish is mainly determined by its genetic factors, but in the end, the disease is determined by the environment. All kinds of stimuli of environment to fish are environmental stress factors. In aquaculture ecosystems, stresses on fish are often caused by environmental factors such as Nonionic ammonia, dissolved oxygen, pH and water temperature. Generally speaking, aquatic products

Stress and the occurrence, prevention and treatment of tail biting disease in pigs
In the current intensive pig production, the phenomenon of pigs biting each other is more common, especially the pigs in the production state are more likely to occur. First, stress. In intensive pig production, the stressors affecting the normal physiological activities of pigs are increasing day by day, which can lead to the decrease of immunity, the enhancement of catabolism, the decrease of anabolism and the disorder of sexual function. in severe cases, it can cause a series of stress syndrome. Such as pale, soft, exudative pork, dry hard dark pork, adult
