Aarden Farms transitioned to batch farrowing in 2007, and they give their experience with the transition. Some of the positives of batch farrowing are that a large group of pigs will become available at one time, breeding is more efficient, farrowing sows receive more attention, and specialized labourers can be trained and/or shared with other farms. The challenges include introducing gilts into the herd, repeats or open sows, hormone costs, and space limitations.
