Résumé
The colostrum quality (immunoglobulin content) is one of the most challenging aspects for hyperprolific sows in the modern pig industry. The objective of this study was to evaluate relationships among sow body condition scores, litter characteristics, and colostrum IgG content in hyperprolific sows, using a digital Brix refractometer to measure IgG. Samples (5 ml) were collected from two hundred and eighty-seven sows within the first hour postpartum. Sow parameters and back fat thickness at farrowing (BFF) and weaning (BFW) were recorded. The results indicate a positive correlation between parity and IgG, as well as BFF and BFW. A negative correlation was found between the number of weaning piglets and BFW. Moreover, a positive correlation was observed between the number of mummified piglets and colostrum IgG. Finally, lactation duration was positively associated with BFF. In conclusion, the number of mummified piglets is a factor positively associated with colostrum IgG content in hyperprolific sows.
