Abstract
In general, longer gestation lengths tend to result in larger calves, more calving difficulty and increased calf mortality rates. However, the relationships are complex, with increased calf mortality rates following short gestation lengths being associated with immaturity, whilst increased calf mortality rates following long gestation lengths are associated with size-related calving difficulty. These analyses were based on calving records of 134,141 Holstein-Friesian cows and calves.
