PSV-20 Effects of Enterid™ in Lactating Sow Diets on Sow and Litter Performance

Abstract

Abstract A total of 196 sows (parity = 2±1.1; farrowed in 5 groups) were used in this study to evaluate the effects of feeding Enterid™ feed additive (a mixture of prebiotics, probiotics, and flavoring compounds, PMI Additives) on sow and litter performance. On day 109 of gestation, sows were moved to farrowing rooms and assigned to one of two dietary treatments, including: control and control + 0.05% Enterid™. Respective diets were fed to the sows from day 109 of gestation to weaning (weaning age: 19±0.13 day). Sow body weight (BW) and backfat thickness were measured at d 109 of gestation, within 24h after-farrow, and at weaning. Sow feed consumption was recorded daily. Individual pig BW was recorded at birth and weaning. A completely randomized design was used to test the effect of diets and ANOVA was performed with mixed models using MIXED procedure in SAS (SAS 9.4, SAS Inc.). Sows fed Enterid™ numerically had greater weaning body weight (BW; 222 kg vs. 217 kg; P = 0.11) and lost less BW (-1.14 vs. -5.38 kg; P = 0.01) and backfat (+0.5 vs. -1.5 mm, P = 0.02) from farrow to weaning compared to the control. In addition, sows fed Enterid™ numerically had greater total lactation feed intake (127 vs 123 kg; P = 0.13) and ADFI (6.64 vs 6.42 kg; P = 0.17). Enterid™ numerically reduced piglet preweaning mortality by 1% (9.15 vs 10.16%). Data of this study suggests that Enterid™ can provide benefits toward improving performance of sows and reducing mortality of preweaning piglets.
