The risk of failure after first service , as well as the risk of death in calf and heifer , was numerically higher in BRSV - infected herds ,
In contrast , BCV infection herd status , <*> was not significantly associated with any production losses in animals from infected herds
The risk of failure after first service , as well as the risk of death in calf and heifer , was numerically higher in BRSV - infected herds , although this was not statistically significant .
In contrast , BCV infection herd status , as defined in the present study , was not significantly associated with any production losses in animals from infected herds compared with those in infection - free herds .
