چکیده

Lactose may affect the immune response mediated from the gut and interact with gastrointestinal microbiota; however no effects of milk-yeast on growth performance were detected. Summary An experiment was conducted to evaluate the effects of dietary lactose alone or in combination with dried milk-yeast product on growth performance , gastrointestinal microbiota, and immune parameters in weanling pigs. Pigs fed lactose and lactose with milk-yeast tended (P = 0.07) to have greater BW compared to control pigs (19.56 and 19.60 vs. 18.55 lb) at the end of phase 1 (week 1 to 2); however, no differences in BW were observed during phase 2 (week 3 to 4), phase 3 (week 5), or overall (week 1 to 5). With respect to growth performance, pigs fed lactose and lactose plus milk-yeast had greater (P = 0.05) ADG, and tended (P = 0.07) to have greater ADFI compared to control pigs during phase 1. There were no differences observed for ADG or ADFI during phase 2, 3, or the overall experimental period. With respect to immune parameters, a main effect of treatment was observed for circulating immunoglobulin (Ig)A where control pigs had greater (P < 0.01) concentrations of IgA compared to pigs fed lactose with or without milk-yeast; however, no effects of dietary treatment were observed for circulating IgG or tumor necrosis factor alpha. Lastly, fecal microbiota of control pigs had a greater microbial diversity index (Shannon's , P = 0.03) compared to pigs fed lactose plus milk-yeast on day 0; however, no differences in microbial diversity indices were observed on days 7 or 14 among dietary treatments. In addition , a shift in microbial composition, limited to a small number of microbial groups, was observed on day 7 with lactose fed pigs having greater (P = 0.05) putative L. jonhsonii staining intensity compared to control pigs and pigs fed lactose plus milk-yeast. On day 14, L. reuteri tended (P = 0.15) to be enhanced , and L. delbrueckii was virtually eliminated (P = 0.04) by feeding lactose with or without milk-yeast. This research indicates that growth performance, immune parameters, and composition of the fecal microbiota may be affected by dietary inclusion of lactose alone or in combination with milk-yeast.

Effects of lactose and yeast-dried milk on growth performance, fecal microbiota, and immune parameters of nursery pigs.

An experiment was conducted to evaluate the effects of dietary lactose alone or in combination with a yeast-dried milk product (50% dried near-dated milk and 50% dried yeast) on growth performance, fecal microbiota, and immune status in nursery pigs (Sus scrofa). A total of 108 pigs (age, 20 ± 1 d; initial BW, 6.07 ± 0.03 kg) were randomly allotted to 18 pens (6 pigs/pen; 6 pens/treatment). Die...

Effects of replacing milk and soybean products with wheat glutens on digestibility of nutrients and growth performance in nursery pigs.

Three experiments were conducted to determine the nutritional value of wheat gluten (WG) for weanling pigs. In Exp. 1, 72 pigs (4.2 kg average BW) were used in a N metabolism experiment. Treatments were 1) casein-corn-based control; 2, 3, 4, 5, and 6) Diet 1 with flash-dried WG, spray-dried WG, two enzyme-modified (to increase solubility) WG, and soybean meal (SBM) used to replace casein, respe...

The impact of environment and antimicrobial agents on the growth response of early-weaned pigs to spray-dried porcine plasma.

Four 28-d experiments involving 360 weanling pigs were conducted to investigate the effects of including spray-dried porcine plasma (SDPP) in diets from d 0 to 14 after weaning followed by feeding a common diet from d 14 to d 28. In Exp. 1, 80 weanling pigs (4.9 kg BW, 17 +/- 1 d of age) were used to determine the effects of substituting 0, 3, 6, 9, or 12% SDPP for dried skim milk (DSM) and L-l...

Effect of protein and(or) carbohydrate fractions of dried whey on performance and nutrient digestibility of early weaned pigs.

One hundred eighty 3-wk-old pigs (initial weight 4.8 kg) were utilized in a 35-d growth trial to determine the effects of the carbohydrate and(or) protein fraction of dried whey on pig performance. In addition, 30, 3-wk-old pigs (initial weight 4.9 kg) were used in two digestion trials to study the effects of the whey fraction on nutrient digestibility. Dietary treatments included a corn-soybea...

Effect of Spray-Dried Plasma and Dried Porcine Solubles on the Growth Performance of Weanling Pigs Raised in Different Health-Status Environments

Introduction Diets of weanling pigs often include spray-dried plasma (SDP) because of its content of immunoglobulins and highquality protein. Another protein source called dried porcine solubles (DPS) has recently emerged. It is a by-product of the heparin extraction from pig intestines. The product is also a high-quality protein source and both SDP and DPS have been shown to result in improved...
