High temperature in summer is easy to cause sudden death of chickens how to prevent sudden death in summer

Chicken

The sudden death of broilers is mainly due to the uncoordinated growth of the whole body and the heart, the rapid development and the heavy burden of the heart. in addition, strong noise, continuous light, sudden change of chicken coop, excessive density and poor ventilation can also increase the incidence of the disease. the incidence of rooster is 3 times higher than that of hen, and it occurs frequently at 2-5 weeks old. In hot summer, it will be induced by high temperature and poor heat dissipation of the body.

Clinical symptoms: diseased chickens did not have any obvious symptoms before the attack, and most of them were suddenly frightened, lost their balance, screamed and ran up when they were eating, drinking or walking around, their wings fluttered violently, fell forward or backward, muscle spasm, landed on their back, and died on the edge of the trough.

Pathological changes: the dead chickens developed well, most of them had a large head, the crown was white, purple, muscle pale, pulmonary congestion, edema, dark red, ventricular emptiness, atrial congestion, bile rupture or bile overflow.

Prevention and control measures: improve the formula, plant oil instead of animal oil, powder instead of granular material; feed restriction; improve the feeding environment, adjust temperature and humidity, maintain hygiene, light can not be too long, appropriate density, strengthen ventilation, reduce stress; drink cool drinking water and supplement multi-vitamins in time.
