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.
在现代养猪业中，初乳质量（免疫球蛋白含量）是高产母猪面临的最具挑战性的方面之一。本研究的目的是使用数字式糖度折射仪测量免疫球蛋白G（IgG），评估高产母猪的体况评分、窝产仔特征和初乳IgG含量之间的关系。在产后第一小时内从287头母猪采集样本（5毫升）。记录母猪参数以及分娩时（BFF）和断奶时（BFW）的背膘厚度。结果表明胎次与IgG之间、BFF与BFW之间呈正相关。断奶仔猪数量与BFW之间呈负相关。此外，木乃伊化仔猪数量与初乳IgG之间呈正相关。最后，泌乳持续时间与BFF呈正相关。总之，木乃伊化仔猪数量是与高产母猪初乳IgG含量呈正相关的一个因素。
