Weaning-to-first service interval: it's impact on subsequent reproductive performance in sows and alternative ways to improve mating efficiency in weaned sows

Weaning-to-first service interval: it's impact on subsequent reproductive performance in sows and alternative ways to improve mating efficiency in weaned sows

Thai Journal of Veterinary Medicine 32(2): 13-21

The objective of this paper is to review current knowledge on the relationship between weaning-to-first-service interval (WSI) in sows and subsequent reproductive performance, in order to optimize and improve mating efficiency. WSI is an important indicator of sows reproductive performance and is closely associated with subsequent fertility. Sows with a WSI of 4-5 days have a larger subsequent litter size, compared to those with a WSI of 7-10 days.
