Effects of climatic seasonal variations and parity on reproductive efficiency at three commercial pig farms in Puebla State



Effects of climatic seasonal variations and parity on reproductive efficiency at three commercial pig farms in Puebla State



Veterinaria, Mexico 17(3): 229



Data on 5457 farrowings over a period of 18 months at 3 pig units in Mexico were analysed. Season of farrowing had a significant effect on the number of liveborn piglets per litter, litter birth weight, number of piglets weaned and lactation length. Parity had a significance on piglet preweaning mortality and the interval from farrowing to 1st service, in addition to the other traits mentioned above.
