Stress is a non-specific reaction caused by a variety of factors to the animal body, which brings many negative effects to the animal’s health and production. It will reduce the animal’s immunity and increase the probability of the animal’s disease. Spring is a transitional season between winter and summer. In spring, the temperature changes greatly and the air is dry. The changeable weather can easily cause stress to animals. If the stress cannot be effectively controlled, it will cause a lot of economic losses to the farm. Therefore, how to solve the impact of stress on farms should be the first problem that practitioners consider.

1.The generation of stress

Poultry are susceptible to disease in spring.

2.The danger of stress

Too little ventilation will cause the deterioration of the air quality in the poultry house and induce various respiratory diseases;

Excessive ventilation will reduce humidity, reduce body temperature, and cause cold stress in poultry.

(1) The harm of too little ventilation

The management does not dare to ventilate or the set ventilation rate is too small. If things go on like this, the result will be the accumulation of ammonia, carbon dioxide and dust. The unfavorable environment will not only induce various respiratory diseases, but also seriously affect the growth rate of poultry and increase the number of poultry. The mortality rate is too small, so too little ventilation is an important factor affecting the production performance.

(2) The harm of cold stress

  1. Effects of cold stress on basal metabolism

When the poultry is in a low temperature environment, the basal energy metabolism rate of the poultry increases, and the feed intake increases. Therefore, in a low temperature environment, the energy of the feed is mainly used to maintain a constant body temperature, which leads to an increase in the consumption of poultry feed, a decrease in the conversion rate, and an increase in the ratio of feed to meat (feed to egg ratio), which reduces the production performance of poultry production; The feed is not enough to maintain the basal metabolism, and the disease will occur due to reduced immunity.

  1. Effects of cold stress on poultry health

① Cause indigestion, diarrhea, enteritis and other gastrointestinal diseases, and clinical symptoms such as diarrhea and overfeeding.

②Respiratory diseases are one of the conditional diseases. Under normal conditions, poultry can carry bacteria without getting sick. When they encounter cold stress, they will induce respiratory diseases (mycoplasma, infectious rhinitis, etc.), and respiratory diseases are various diseases. Booster, increase the probability of contracting avian influenza and other diseases, and present a superimposed effect with other diseases, aggravate the clinical symptoms of the disease, and bring difficulties to the treatment and medication of the disease.

③Cold stress can also lead to a decline in the immunity of chickens, resulting in immune failure and frequent diseases in poultry.

Cold stress can not only cause disease in poultry, but also cause immune failure. Therefore, it is one of the important factors that threaten the health of poultry.
