Last year i experienced an IB breakout on a broiler house adjacent to Layer Farm (8 wk Age). Signs appeared just after administration of 4/91 IB Vacc. In broiler it caused about 6% mortality & same time Layer birds also showed respiratory signs but with little mortality .
Now that flock is at 38 wk Age but production is 83% with peak around 86%.
This indicates that variant (QX or 4/91) do have a impact on layer performance if it occurs in early stages.
