The ingredients of poultry feeds are chosen based on the least-cost formulation to meet nutritional requirements. However, this approach can lead to the introduction of anti-nutritional ingredients in the feed. The objective of this study was to evaluate the impacts of two diets (with or without prebiotic) on homeostatic genes in the liver and spleen of laying hens. Hy-Line Brown layers were raised either on a soybean meal or cottonseed meal-based diets with and without an added prebiotic (yeast cell wall), totaling four experimental diets. A total of 120, 63-week old layers were housed individually in a wire cage system. We investigated differences in the expression of select homeostatic marker genes in the liver and spleen of hens from each treatment. We then used the ΔΔCT and generalized linear models to assess significance. Results show that the inclusion of prebiotic yeast cell-wall (YCW) increased the expression of the BAK gene in the liver tissue for both the soybean meal (SBM) and cottonseed meal (CSM) diets. For splenic tissue, the combination of YCW with the CSM diet increased the POR gene over six log2 fold. Altogether, our results suggest altered homeostasis, which can have consequences for health and performance.

Abstract Live yeast and yeast cell wall products potentially improve health and performance in cattle during the stocker and feedlot phases. Therefore, the objective of this study was to investigate yeast-product supplementation during late gestation through 88 d of age, and(or) a 42-d backgrounding period on immune function and growth performance. Late gestation cows (n = 97) were assigned randomly to treatment: 1) supplement without yeast (CON) or 2) supplement with yeast products (YP). At weaning, calves from each dam treatment (CON or YP) were pooled by dam treatment and stratified based on BW, sex, dam parity, and sire and split into 8 pens within dam treatment. Pens were assigned randomly to 1 of 2 backgrounding treatments (CON or YP) such that a total of 4 pens/treatment existed. Treatments included: 1) dam YP, calf YP, 2) dam YP, calf CON, 3) dam CON, calf YP, and 4) dam CON, calf CON. Calves were fed 2 kg/d of grain and yeast (5 g/d) was provided in a top-dress (ground corn plus YP). Weaning weights (P = 0.99) and backgrounding ADG (P = 0.29) did not differ. Total ruminal VFA concentrations, sampled on d 0 and 42 post-weaning, were increased in calves from dams supplemented with YP (P = 0.04). There were no effects of treatment (P ≥ 0.32) on molar proportions of acetate and propionate. Haptoglobin (P ≥ 0.49) and neutrophil:lymphocyte ratio (P ≥ 0.46) were not influenced by treatment but were affected by day (P < 0.01). While there was no effect of YP (P = 0.73) on BVD titers, there was a day effect (P < 0.01) where titers were greatest on d 28 and least on d 0. Post-weaning yeast supplementation in combination with dam supplementation did not improve calf immune function or performance during a 42-d backgrounding period.
