Anti-stress drug

Stress, also known as stress response, refers to the sum of the body's non-specific response to various stimuli and is a comprehensive response of the hypothalamic-pituitary-adrenal system. In intensive farming, various stress factors include feeding factors (such as capture, transfer, transportation, vaccination, drug injection, forced moulting, breaking, etc.), environmental factors (such as high temperature, cold, noise, and harmful). Gases, etc. and pathogen infections (such as viruses, mycoplasma, bacteria, parasites, etc.) can cause stress reactions in livestock and poultry, which can cause slow growth of animals, decline in production performance, weakening of disease resistance and even death, giving animal husbandry The damage caused is huge. Anti-stress drugs are drugs that prevent stress and reduce stress. An excellent anti-stress drug should have the following characteristics: It can significantly reduce the stress response of animals, does not affect the normal activities of animals and the formation of antibodies, and no drug residues. At present, anti-stress drugs are still in the experimental stage or clinical experience application level. Anti-stress drugs are generally divided into three categories: Stress-preventing drugs: Can weaken the effects of stress factors on the body, such as tranquilizers, sedatives, etc.; Adaptation drugs: can improve the body's defense, can ease the regulation of stimulation Butylazole, fumarate, vitamin C, acanthopanax, etc. Symptomatic drugs: refers to drugs that fight stress symptoms. The above classification is relative. A drug can prevent stress and promote adaptation, and is both a stress-preventing drug and an adaptive drug.
