Abstract

Objective: The present study aimed to evaluate the effects of bacteriophage cocktail supplementation in diet of gestation sows on both the sows and their progeny.

Methods: A total of 57 F1 multiparous sows (Yorkshire×Landrace) were allotted to one of three treatment groups in a completely randomized design. The sows were fed cornsoybean meal-based diet supplemented with 0%, 0.05%, or 0.10% of a bacteriophage cocktail during the gestation, followed by a common diet during lactation. Body weight and backfat thickness were measured during the trial along with blood collection for immunoglobulin analysis. Fecal samples were collected on 4, 6, 8, and 10 weeks of gestation period to examine fecal microflora. Litter performance and milk composition were investigated at 24 hrs postpartum and on d 21 of lactation.

Results: Increasing bacteriophage cocktail supplementation levels in gestation diets resulted in linear increas (p<0.05) in feed intake of lactating sows and in the weight of live litters, while showing quadratic increas (p<0.05) in litter weight gain from d 0 to 21 of lactation. Dietary treatment had no impact on the serum concentrations of IgG and IgM in the sows. Increasing dietary bacteriophage cocktail levels in gestation diets resulted in a linear increas (p<0.05) in the fat content of colostrum. The elevation of dietary bacteriophage cocktail in microflora of sows resluted in a significant increase (p<0.05) in Lactobacillus count for d 63 and 105 of the gestation period, while concurrently decreasing Escherichia coli (E. coli; p<0.05) and Salmonella (p<0.10) counts during the late gestation period.

Conclusion: The supplementation of a 0.05% bacteriophage cocktail in the diet of gestating sows could improve total litter weight, alive litter weight at birth, and litter weight gain during the lactation. This effect is attributed to positive changes in fecal microflora with an increase of Lactobacillus and a decrease of E. coli and Salmonella.

妊娠日粮中添加鸡尾酒噬菌体对母猪繁殖性能、血液特征、乳成分和粪便微生物群的影响。
目的:研究在妊娠母猪日粮中添加鸡尾酒噬菌体对妊娠母猪及其后代的影响。方法:选用57头F1产母猪(大约克×长),采用完全随机设计分为3个处理组。妊娠期饲喂在玉米-豆粕基础饲粮中添加0、0.05和0.10%混合噬菌体的试验饲粮,哺乳期饲喂普通饲粮。在整个试验过程中测量体重和背部厚度,同时采集血液进行免疫球蛋白分析。分别于妊娠4、6、8、10周采集粪便样本,测定粪便微生物区系。分别于产后24 h和产后21 d调查产仔性能和乳成分。结果:在妊娠期饲粮中增加鸡尾酒噬菌体添加水平,可线性提高泌乳母猪采食量和窝重(P < 0.05),并二次提高窝重(P < 0.05)。饲粮处理对母猪血清免疫球蛋白G和免疫球蛋白M浓度没有影响。提高妊娠期饲粮中噬菌体鸡尾酒水平,可线性提高初乳脂肪含量(P < 0.05)。在母猪粪便菌群中,饲粮中添加噬菌体鸡尾酒显著提高了妊娠期第63天和第105天乳酸菌数量(P < 0.05),显著降低了妊娠后期大肠杆菌数量(P < 0.05)和沙门氏菌数量(P < 0.10)。结论:在妊娠母猪饲粮中添加0.05%的噬菌体鸡尾酒可通过改善粪菌群,增加乳酸菌数量,减少大肠杆菌和沙门氏菌数量,提高母猪初生窝重、活窝重和泌乳期窝增重。
