Lactation with cows and milk, watch my nipples squirt, (Amateur)
The answer comes down to a physical limitation: sows are very difficult to milk. So I made this casserole instead. This dilute milk may have something to do with the animals' slow reproductive cycle. I was determined to breastfeed, and after some hiccups in the beginning, I managed to get quite good at it. By the time they are weaned, they are almost double in weight, researchers have found.
The high-fat diet helps the pups put on a thick layer of blubber that serves to insulate their bodies against the harsh, cold environment, says Amy Skibiel, a lactation expert at the University of Florida. By contrast, cows store their milk in their udders and can eject milk continuously for several minutes at a time. That said, it seemed like a really, really, easy food to sneak a little boob juice into, so I figure why not.
