Performance Economics of Broiler Rearing with Reovirus Infection

The broiler birds after experimental challenge with virulent MAS reovirus developed infection. This infection resulted into poor body weights, uneven growth, poor FCR, poor BPEI and poor PEI. The uninfected birds showed uniform live weights, even growth, better FCR, better BPEI and better PEI. The group with reovirus infection resulted into economic loss while uninfected group resulted into pro...
