Dear Lactnet Friends:

"Researchers in the UK recently studied the effects of calving ease on the
fertility and production of 50,000 first lactation Holsteins and their
10,000 Holstein heifer calf offspring. The study had two main objectives:

  1.

Estimate the effect of a difficult calving on the subsequent first
lactation production.

2.

Estimate the effect of a difficult birth on the calf as a mature animal.

Based on these objectives, researchers reported the following results in
the November 2011 issue of *Journal of Dairy Science*:

•

Cows requiring vet-assisted calving required 0.7 more services to conceive,
needed an additional eight days to reach first breeding and had a 28-day
longer calving interval.

•

Milk losses were significantly higher in cows with calving difficulties,
producing approximately 4.4 pounds less milk per day than cows without
calving difficulties.

•

Calves born as a result of a difficult calving produced 1,565 pounds less
milk in their first lactation compared to calves born without difficulty,
showing a lifelong effect of difficult calvings."
