farrowing index
the number of times a sow (herd) farrows in a 365 day period. It, along with litter size and mortality from birth to marketing, determines the number of pigs marketed per sow per year (PMSY). Weaning at 8 weeks of age potentially allows a farrowing index of 2. Weaning at 3 weeks of age potentially allows a farrowing index of 2.5.
isolated farrowing program
sows are farrowed in isolation as a means of preventing the spread of enzootic diseases, especially atrophic rhinitis and enzootic pneumonia.
farrowing rate
the number of sows that farrow divided by the number mated.
