What's wrong with chickens dying all the time in hot weather?

It may be heatstroke. Chicken heatstroke, also known as heat exhaustion, is a general term for heatstroke (caused by direct sunlight) and heatstroke (the ambient temperature and humidity are too high, so that body heat cannot be emitted), and it is a common disease of chickens in hot summer. The disease is characterized by the acute death of chickens. Generally, when the temperature exceeds 36℃, chickens can suffer from heatstroke, and when the ambient temperature exceeds 40℃, they can die in large numbers.

Symptoms-shortness of breath at the beginning of the chicken disease, panting with the mouth open, wings open, and a "giggle" sound; The cockscomb and moustache are bloodshot and bright red first, then cyanosis (blue-purple), and some are pale; A rise in body temperature is heat; Loss of appetite or disappearance, increased water consumption, serious non-drinking; Can't stand it, fell asleep, collapsed and died. Most deaths occur in the afternoon and the first half of the night. Cage chickens are more serious than flat chickens, and the upper cage chickens die more.

Prevention and control-

1. Reduce the temperature of the henhouse: ventilate to cool down, and the longitudinal ventilation effect is good; When the temperature of the henhouse exceeds 32℃, a sprayer with a rotating nozzle can be used to spray water on the top or wall of the henhouse. In dog days, you can spray water directly on the chicken with a high-pressure low-fog sprayer, and set a water curtain at the air inlet to let the air cool before entering the chicken house. In some places, chickens are sprayed with deep well water and disinfectant many times.

2. Do a good job of greening around the henhouse: Planting trees around the henhouse for shading and greening can reduce the thermal radiation by 50% ~ 60%, but it does not affect the natural ventilation of the henhouse.

3. Adjust the feed ratio: Because the feed intake of chickens decreases by 65,438 0.6% every time the temperature rises by 65,438 0℃, high-concentration diet should be adopted. Plant protein is often used in feed to avoid the decrease of feed intake caused by chicken's anorexia of animal protein feed during high fever. It can increase 3%-4% of bean cake, 1%-2% of leaf powder and bran, reduce fat content and feed more green feed.

4. Adjust the feeding time: feed the chickens when the temperature is cool, preferably at 4-5 am and 5-6 pm.

Strengthening feeding management: the frequency of mixing materials can be increased, and adding a little water to mix materials every time can stimulate the appetite of chickens; Supply sufficient fresh clean water, and change the water every 2 hours 1 time from morning 10 to 4 pm; Lighting in the morning and evening shall be implemented, with lights turned on at 4: 00 a.m. and lights turned off at 9: 00 p.m., and materials shall be fed 10- 15 minutes after lights are turned on.

5. Enhance the anti-stress ability of chickens: When the house temperature exceeds 36℃, 50g of Azone can be added to every100kg of water for chickens to drink freely.

6. Timely treatment: once the chicken is found lying unconscious on the ground, it should be moved to a cool and ventilated place as soon as possible, soaked with cold water spray and fed with water solution to relieve stress. Adult chickens usually recover quickly after each oral administration of 1 pill.
