It depends. India does have some factory farms, mainly for beef. But many dairy cattle are kept by small farmers for whom the milk and meat are a supplement to whatever plants they grow. And these farmers usually belong to dairy co-operative societies like Amul, which do quality control and ensure that the animals are not abused too much. Also some Indian states ban or heavily restrict the slaughter of cattle (although in practise this just leads to them being abandoned or disappearing into the black market).
