Twenty-eight mixed parity sows (Line 241; DNA) and their offspring were used to evaluate live yeast supplementation during lactation with or without a pre/probiotic combination during the nursery period on lactation performance, lifetime growth performance, and immune response. On d 110 of gestation, sows were allotted to a lactation diet with or without a live yeast probiotic (0.10% Actisaf Sc 47 HR+; Phileo by Lesaffre, Milwaukee, WI). At weaning, their offspring (350 pigs; initially 6.1 ± 0.02 kg) were randomly assigned in a 2 × 2 factorial with main effects of sow treatment and nursery treatment consisting of a control diet or a diet with a yeast cell-wall prebiotic and Bacillus subtilis probiotic (0.10% YB; Phileo by Lesaffre, Milwaukee, WI) fed for 42 d followed by common diets fed until marketing. Two nursery pens were combined into 1 finishing pen, such that there were 5 and 10 pigs per pen with 17 or 18 and 8 or 9 replications per treatment during the nursery and finishing periods, respectively. There were no significant effects of yeast supplementation on lactation performance (P ≥ 0.079). There was a sow × nursery diet interaction (P = 0.024) on nursery ADG. Pigs from yeast fed sows had increased ADG when fed control nursery diets compared to pigs from control sows fed the control nursery diet with pigs fed pre/probiotic nursery diets intermediate, regardless of sow diet. Pigs from yeast fed sows tended (P = 0.067) to have greater final BW (d 165). A subset of pigs was sampled throughout their lifetime to determine serum porcine circovirus type 2 (PCV2) and Mycoplasma hyopneumoniae antibody sample-to-positive (S/P) ratios and percentage inhibition of Lawsonia intracellularis. There was a tendency for a PCV2 S/P ratio sow diet × day interaction (P = 0.097) where progeny from yeast fed sows had higher PCV2 S/P ratios at 101 d of age compared to control sow progeny (P = 0.046). There was a PCV2 S/P ratio nursery diet × day interaction (P = 0.036) where pigs fed a pre/probiotic combination had reduced S/P ratios at 66, 78, and 162 d of age (P ≥ 0.022); however, at 22 d of age pigs fed a pre/probiotic combination tended to have an increased S/P ratio (P = 0.051). In conclusion, effects of combining a yeast probiotic in lactation diets and a pre/probiotic in nursery diets were not additive. However, feeding a live yeast probiotic during lactation resulted in tendencies (P ≥ 0.10) for increased progeny final BW and HCW.

哺乳期酵母益生菌和保育期酵母细胞壁益生元和枯草芽孢杆菌益生菌对终生生长性能、免疫反应和胴体特性的影响


28 头混胎母猪（第 241 行;DNA） 及其后代用于评估哺乳期补充活酵母（有或没有前生元/益生菌组合）对泌乳性能、终生生长性能和免疫反应的影响。在妊娠第 110 天，将母猪分配到有或没有活酵母益生菌的哺乳日粮（0.10% Actisaf Sc 47 HR+;Phileo by Lesaffre，威斯康星州密尔沃基）。断奶时，它们的后代（350 头猪;最初为 6.1 ± 0.02 公斤）被随机分配到 2 × 2 个析因中，母猪处理和保育处理的主要效果包括对照日粮或含有酵母细胞壁益生元和枯草芽孢杆菌益生菌的日粮（0.10% YB;Phileo by Lesaffre， Milwaukee， WI） 饲喂 42 天，然后饲喂普通饮食直至上市。将两个保育栏合并为 1 个育肥栏，每个猪栏有 5 头和 10 头猪，在保育期和育肥期，每个处理分别有 17 或 18 头和 8 或 9 次重复。补充酵母对泌乳性能没有显着影响 （P ≥ 0.079）。母猪×保育日粮的相互作用对保育日粮 （P = 0.024） 的影响。与饲喂对照保育日粮的对照母猪相比，饲喂对照保育日粮的对照母猪的猪平均增重，无论母猪日粮如何，无论母猪日粮如何。酵母喂养母猪的猪往往 （P = 0.067） 具有更高的最终体重 （d 165）。对猪的整个生命周期进行取样，以确定血清猪圆环病毒 2 型 （PCV2） 和猪肺炎支原体抗体样本与阳性 （S/P） 的比率和细胞内劳森菌的抑制百分比。在日间交互作用中，母猪×日粮的 PCV2 S/P 比值有趋势 （P = 0.097），其中酵母喂养母猪的后代在 101 日龄时与对照母猪后代相比具有更高的 PCV2 S/P 比值 （P = 0.046）。存在 PCV2 S/P 比率保育×日间日粮相互作用 （P = 0.036），其中饲喂益生元/益生菌组合的猪在 66、78 和 162 日龄时 S/P 比率降低 （P ≥ 0.022）;然而，在 22 日龄时，饲喂益生元/益生菌组合的猪往往具有增加的 S/P 比 （P = 0.051）。总之，在哺乳期日粮中结合酵母益生菌与在育苗日粮中结合益生元/益生菌的效果不是累加的。然而，在哺乳期间喂养活酵母益生菌导致后代最终 BW 和 HCW 增加的趋势 （P ≥ 0.10）。
