Pigs have shorter pregnancies too, at 115 days. Pigs are ready for market from 5 to 7 months of age.

Cattle have a 263 day pregnancy with most pregnancies producing 1 calf although cows do have twin births.
The average market age is between 12 to 24 months and they have to weigh at least 1200 pounds.

Most of the farmers I know raise pigs. The cattle herds are not very large, and not as many farmers raise cattle. (at least in Kentucky) Most cattle are raised for beef although a few folks have dairy herds.

Costco has some incredible boneless pork chops, about 2 inches tall at $2.40 or thereabouts per pound. I buy a package about every 6 weeks - they look a lot like a beef filet mignon.
