Grazing sows’ fecundity varied depending on the age of primiparous grazing sows, with a fecundity percentage o f 86.0%, while in multiparous grazing sows, fecundity percentage was 75.3%. Heat appearance post-partum after a period of breast-feeding of 6 weeks, manifested in 85.3% in primiparous grazing sows and 88.4% in multiparous ones in the first heat cycle and 4.2% and 3.7% respectively in the second heat cycle. |
