在从妊娠第90天到哺乳第28天的33头第一窝母猪的实验中，测试了益生菌补充剂对体重表现、采食量、窝仔数、窝仔重量、健康状况和微生物概况的影响。将屎肠球菌DSM 7134以5 × 10（8）CFU/kg饲料的浓度补充到后备母猪的妊娠期和哺乳期饲料中。补充母猪表现出显著更高的改善饲料摄入量（4.16与3.71公斤/天），窝产仔数（9.2与7.7仔猪）和体重性能。益生菌母猪在泌乳第28天的平均活重比对照组高11 kg。每克粪便的细菌数（乳酸杆菌、革兰氏阳性厌氧菌、革兰氏阴性厌氧菌、大肠埃希菌和肠球菌）以及粘附性和溶血性大肠埃希菌的发生率。大肠杆菌微生物显示两组母猪或其仔猪之间无显著差异。虽然窝仔数不一定被认为是益生菌补充剂的主要作用，但显著更好的采食量和体重表现可能部分归因于益生菌的使用，并且可以防止幼母猪在第一窝后的“饥饿不育”，所述“饥饿不育”是由哺乳期间采食量减少引起的，伴随着身体组织的高度动员以及能量缺乏。
In an experiment with 33 first-litter sows from day 90 of pregnancy to day 28 of lactation, the influence of a probiotic supplementation on weight performance, feed intake, litter sizes, litter weights, health status and microbiological profile was tested. Enterococcus faecium DSM 7134 was supplemented in a concentration of 5 x 10(8) CFU/kg feed to the gestation and lactation diets of gilts. The supplemented sows showed a significant higher improvement of feed intake (4.16 vs. 3.71 kg/day), litter size (9.2 vs. 7.7 piglets) and weight performance. The average live weight of the probiotic sows at day 28 of lactation was 11 kg higher than of the controls. The bacterial counts/g faeces (lactobacilli, Gram-positive anaerobes, Gram-negative anaerobes, Escherichia coli and enterococci) and the incidence of adhesive and haemolytic E. coli organisms revealed no significant differences between the sows of the two groups or their piglets. While the litter size cannot necessarily be assumed as a primary effect of the probiotic supplementation, the significantly better feed intake and weight performance might be partly due to the probiotic use and can prevent 'starvation sterility' of young sows after their first litter caused by reduced feed intake during lactation with high mobilization of body tissue accompanied with lack of energy.
