It depends on how intensive the setup is. My grandparents had about 3 pigs, 2 cows and one horse in a common animal yard, covered in large, raised river stone, and a yard within the yard just for the pigs. The pigs also had a separate stable room for sleeping (really dirty indeed) and the cows and horse would sleep together in the same stable room (even though they had available individual rooms, I guess the horse didn't like to sleep alone). I think they cleaned the pig yard every couple of weeks; they had to clean the stables every few days and the common animal yard once per season. It was common in older days that pigs were raised in communal mountain herds, they were semi-wild, foraging in the woods, mostly on beech nuts, but they would return in the evening at a common stable/den. Anyway, cleaning wasn't the hardest part, imho, but bringing water and hay/food for the larger animals was, especially in bad weather. I find it astonishing how little "foreign" food the pigs required. It was scraps from us and special nutritious weeds from vegetable gardens. In later years people started intensively feeding the pigs and they do get higher yields/less work.
