The ALFFcup system is currently implemented in two ways by our customers in the Netherlands:
System 1: Two extra piglets per sow.
Install a cup in select farrowing crates, generally nearest to the entrance. For example, if there are two more piglets than functional teats, the system ensures additional milk is provided as needed.
System 2: 40 piglets per two sows.
Combine the extra piglets from two sows, with a maximum of 40 piglets per two sows. If the average litter size is 15 piglets, add 10 extra piglets to these two sows. These sows should be positioned next to each other, and the dividing sidewall between the farrowing crates should be removable. A minimum of two cups should be installed in these two crates, preferably four cups if possible.
