Abstract

Consistent feed intake during the stress of gestation and lactation in the sow may help maintain the wellbeing of the sow and resulting litter. The effects of the consumption of the appetizing ingredient M. cordata extract preparation (MCEP; trade name Sangrovit®) added to the feed at 50 and 100 ppm on the wellbeing and growth in the late gestation and lactation phases of sows and the resulting piglets prior to weaning was evaluated in preliminary and confirmatory feeding trials. Small increases in sow feed intake and piglet body weights were found in the preliminary trials. In the confirmatory field trial, low increases in sow feed intake with Sangrovit® resulted in decreased sow backfat loss and increased (P P ® to sow feed during late gestation and lactation has positive effects on both the sows and the resulting litters.

Highlights

Consistent feed consumption by the sow is critical to sustained health of the animal through the stressful time of gestation and lactation, as well as the health and growth of the piglets
The slight increase in sow feed intake may have resulted in increased milk production, which could have been the reason for the increased number of piglets reaching weaning age (Table 3)
The Sangrovit -fed group had a higher number of piglets/sow (4.7% greater than control), which was correlated with a decreased body weight/piglet (Table 4)

Summary

Introduction

Consistent feed consumption by the sow is critical to sustained health of the animal through the stressful time of gestation and lactation, as well as the health and growth of the piglets. Plant-based organoleptic feed ingredients, such as essential oils, herbs and other phytogenic substances are being added to swine feed to help maintain or increase feed palatability and overall health and growth of the swine [4]. Previous studies have evaluated the consumption of MCEP by growing and finishing swine [5] [6], with Sangrovit added to the diet at 50 ppm providing a positive effect on body weight gain and feed conversion rate in weanling and growing swine [7] [8]; little is known on the consumption of Sangrovit by sows during gestation and lactation. To that end, feeding trials have been conducted with Sangrovit consumed in the diet by sows during the late gestation phase through piglet weaning
