如果我们讨论群体饲养,映入脑海的第一件事是这是欧洲小型猪场所做的事,这些猪场的仔猪每三周断奶一次。这并没有远离现实。以群进行饲养,意味着无论仔猪每周、每二周、每三周、每四周甚至每五周断奶一次或二次,都应按批次将所有的母猪组织起来。在考虑采取群体饲养时,猪群的大小也不是一个限制因素:我们可以组建成一个100头或100 000头母猪的群体。的确,采取群养是有必要的。今天,为了在养猪生产中有利可图,我们需要对猪场的猪群按批次进行组群。
The first thing that comes to mind when we talk about group feeding is that this is what European mini-farms do and the piglets in these farms are weaned every three weeks. This is not far from reality. Raising in groups means that all sows should be organized in batches regardless of whether they are weaned once or twice a week, every three weeks, every four weeks, or even every five weeks. The size of a herd is also not a limiting factor when considering group rearing: we can group a population of 100 or 100 000 sows. Indeed, it is necessary to adopt group culture. Today, to make a profit in pig production, we need to group swine herds on a farm-by-batch basis.
