Order when entering the sows from the pregnancy to the farrowing quarters in big farms
In the previous piece of advice we saw that in small farms it could be interesting to maintain a certain order when entering the sows in the farrowing quarters depending on their parturition. Nevertheless, in big farms or in farms that group together many farrowings at the same time we will have to think about the order in another way, because if the farrowing quarters are not very big we will have the same batch of sows housed in several rooms.
