Not seasonal, but easier to breed in summer due to cost. Left in for 6 weeks (2 estrous cycles). Ru doesn"t know when they will give birth. Tail docking because they don"t have muscles to lift their tails. This can result in defecation build up and fly strike (maggots). Pen breed: bring ram/buck from outside to have genetic diversity. Pen breed: bring ram/buck from outside to have genetic diversity. elastrator method (cuts of circulation and they fall off) Disbudded (horns) prior to eruption from skin (1-10 days). No breed totally polled besides a dorset breed. Males are castrated between 6-8 weeks as we want to leave production of testosterone as long as possible. Ru uses elastrator method (cuts of circulation and they fall. Heat/estrus check: if the swine displays signs of estrus, she is not pregnant. Pen breeding: detect estrus and leave male and female together for. Intense breeding for heterosis: passing of superior genes.
