In addition to this genetic trend, we see this first-hand in our Elite Farms performance. The percentage of females with low birthweights has decreased 6\u2006% (from 14\u2006% to 8\u2006%) over the last five years.<\/p>\n\n\n\n

Pre-wean survivability<\/h3>\n\n\n\n
Are those piglets surviving? We measure the survivability of those litters. Over the past year, the genetic trend for pre-wean survivability has been 1,7\u2006%. (Figure 2) Driving this trend are heavier, robust piglets and sow milking ability.<\/p>\n\n\n\n

Litter weaning weight & milking ability<\/h3>\n\n\n\n
Piglets rely solely on their dam for nutrition until weaning. To wean healthy, consistent litters, sows must provide ample colostrum and milk for all piglets. A sow\u2019s ability to milk and milk quality is positively influenced by genetics, proper gestational nutrition, and management.
Colostrum provides newborn piglets with energy and hydration to maintain vital body functions. It also provides antibodies critical for protection against disease, serving as the basis of a piglet\u2019s immune system development. Colostrum intake is positively associated with pre-weaning survival and weaning weight.
We select on litter weaning weight for milk yield. Genetic potential for litter weaning weight in PIC Elite Farms has increased 1,22\u2006kg per litter in the last year, which corresponds to an increase in individual pig weaning weight just over 57\u2006g per pig.
The number of teats counts too. Having an adequate number of functional teats to nurse pigs reduces the need for nurse sows and extra labor to move and manage pigs. In the past year at PIC Elite Farms 58% of gilts had 16 or more functional teats and 95\u2006% had 14 or more functional teats.<\/p>\n\n\n\n
Putting it all together<\/h2>\n\n\n\n
We\u2019re excited our females are poised to be strong, predictable, and efficient mothers producing quality weaned pigs. We also know daily management variables play a crucial role in reaching genetic potential on farms. Our technical service team continues to evaluate and update management practices recommendations to help producers achieve genetic potential.<\/p>\n\n\n\n
