Granted they’re not a large as a calf, but there is not much meat on a lamb either. A mother pig makes a lot more offspring per birth than a lamb too. Why isn’t baby pig a common food?
Cubans have a way of grilling a young (not fetal, but about 2 - 3 feet long) pig, wrapped in banana leaves and basted frequently with criollo sauce, that is just divine. Cooking takes the better part of a day when done this way, but the wait is worth it.
I’ve seen little pigs being roasted on a stick over an open fire in Greece, in what seems to be looked at as a “little pig only”-barbeque event and I got the impression this custom is overthere as common as a barbeque in the USA.
Babypigs prepared in different ways are also on the menu in other nations I know of (Not in mine :)…)
Whole suckling pigs aside, the reason you don’t see cuts of meat from young pigs like you see veal:
It might be a matter of economics. Pigs grow remarkably quickly[sup]1[/sup]. In 10-12 weeks after birth you have a 40 or 50 pound “feeder pig”, and at about 6 months of age they are ready to become pork chops. The beef you buy in a store was probably from a 12 to 18 month old steer, and sometimes cattle are held to an older age than that.
Pigs are much more efficient converters of feed into meat than cattle are. Historically, they had a large advantage in being able to grow fat eating garbage - a small farmer could keep a couple pigs and feed them mostly on waste from other parts of his operation.
Given these factors, there’s not much incentive to slaughter the pig before it’s full grown.
[sup]1[/sup] - In fact, when the movie “Babe” was shot, they used 48 pigs, partially because the ones they started with grew visibly during the filming.
Is there much of a taste difference in the meat, between baby and grown pigs? I know that lamb and veal are significantly different from mutton and beef.
