Pa Archives provides the tax lists of some townships for 1700's. For instance Jacob Doub of Salford Township Montgomery County Maryland had 50 acres and only 2 cattle. No horses or sheep.
Cattle for beef didn't appear to be very high on the priority lists. Perhaps as beasts of burden, but the lists don't indicate any cattle barons.
http://files.usgwarchives.net/pa/bucks/taxlist/1779-rockhill2.txtConsidering that cattle have an 11 month gestation period, and farmers wanting beasts of burden wouldn't want the hassle of keeping a bull. It seems that there wouldn't be enough cattle to produce a single animal for slaughter per household per year. Several of my ancestors are listed on this list. For instance Henry Freed had 9 children. He had more cattle than both,but still the numbers are way down to support slaughter for meat.
According to one of the Civil War specials I watched a few months ago, pork was actually the most prevalent meat until the 1860's, when beef surpassed pork in use. Hams could be cured and kept for months.
I suspect wild game, and lesser animals provided the table protein.
