Signs from day 2

I had same type of experience in broiler chicks as your posted photograph & description. Usually we used to treat this type of cases with combined vitamins, but did not get any response. After failure of mentioned treatment , I tried it with antiviral drug along with previous, but result was not satisfactory. I am also confused , it might be Avian encephalomyelitis virus infection .

Normally , the problem come from the Hatcher , the temperature before chick hatch variance and too high in some period.

This condition comes in chicks for following reasons 1. Hatchery problem - If reo virus infection carries from parents to chick then arthritis problem seen in chicks. The signs includes lameness, leg bending, low feed consumption and high mortality. This situation is difficult to treat. Only preventive medicines including high dose of vitamin E with selenium, antiviral spray can be done. Problem should be treated in parent flock by doing suitable vaccine. 2. Management problem - When chicks hatched, they already have yolk. They need some time to absorb this yolk. During this period, if we supplement highprotein (above 23%) feed, that time also this problem is seen. High protein diet result in unutilised yolk which will infected by bacteria. Also high protein resulted kidney failure and ascites which finally leads to lameness, lateral recumbancy with eyes swollen and closed. Lesions are seen in kidney. Mortality is due to inability to drink water and eat feed. In this situation, first check the protein level in feed then give birds low protein diet or maize alone for 1-2 days along with kidney tonic and Vitamin E with selenium.

It is really good
