The IB Variant disease had been found in my country some ten years ago. I had diagnosed it as NEPHRITIC
IB. It was confirmed by the Weybridge Laboratory. At that time, I did not want to introduce the IB VARIANT vaccines. The vaccine IB MA 5 had controlled the disease a bit. But in outbreaks, the mortality was very high in broilers. The litter became muddy. Severe diarrhoea. Nowadays, we are using the TWO vaccines, namely, the IB VARIANT 4 / 91 from Intervet and the IBIRD from CEVA. The day old chicks are being vaccinated at the Hatchery by coarse spray. The vaccinated flocks are well protected.

RTI in broilers, layers and breeders quite common.
But isolation and characterization of virus in needed. But presently poultry consultant tackle the problem.
