An attempt to improve farrowing kinetics and post-farrowing activity of sows using sucrose as energy supplement before and after farrowing

The pre-farrowing energy status of sows plays a pivotal role in determining farrowing success and in sustaining the health and vitality of sows and their piglets during the immediate post-farrowing period. This study examined the effects of sucrose supplementation on reproductive performance, farrowing kinetics, standing behavior of sows, and piglet vitality. Twelve multiparous sows were randomly assigned to three groups: Control (CON), Water + Sucrose (WSS), and Feed + Sucrose (FSS). In the WSS, 100 g of sucrose was dissolved in 1.9 L of water and provided in the feeder. In the FSS, 100 g of sucrose was directly added on top of the feed. Sucrose was provided three times daily for 6 days, starting 3 days before farrowing and continuing for 3 days after. Results revealed no significant effects on sow reproductive performance, litter growth performance, and farrowing kinetics. However, piglets from sugar-supplemented sows tended to reach their first bout in a shorter period (P = 0.092), suggesting improved early vitality. FSS sows exhibited significantly higher standing frequency on day 1 post-farrowing, enhanced postpartum activity, and potential improvement in recovery. In conclusion, sucrose supplementation from 3 days before to 3 days after farrowing, particularly on top of feed, may contribute to improved postpartum activity. However, its physiological effects require further clarification. Further studies incorporating metabolic indicators and larger sample sizes are recommended to validate these findings.
