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.

Abstract As the most immediate membrane surrounding the fetus, the amnion carries great potential as a microbial source of inoculation for the calf’s rumen microbiome. We hypothesize the calf is exposed to a microbial source prior to birth, and that the amnion plays an essential role in inoculation prepartum. Our objective was to isolate and identify microbes of the amniotic fluid and vaginal canal during late gestation and compare these populations to rumen fluid and meconium of newborn calves. Vaginal (VAG) and amniotic fluid (AF) samples were obtained from multiparous beef cows (n = 10) 10 days prior to their expected calving date. Rumen fluid (RF) and meconium (MEC) samples were obtained from each newborn calf immediately following parturition. Microbial DNA was isolated and purified utilizing the QIAmp DNA Stool Minikit (Qiagen) for amplicon 16S rRNA sequencing. All analysis was performed in QIIME2. Alpha-diversity was not different between MEC and AF (q ≥ 0.09) under any metric, but MEC and VAG differed under Faith’s Phylogenetic Diversity (q = 0.03). The MEC, AF, and VAG all differed in beta-diversity (q = 0.003). The degree of similarity between AF and MEC may indicate the AF plays a crucial role in the colonization of the fetal gut prepartum. Each of these lines of evidence outline fundamental aspects of the unfolding amnion-fetal gut-microbial axis, and provide key targets for future research into rumen development and the manipulation of feed efficiency in beef calves.

Theobjective of this study was to evaluate the effects of metabolizable proteinand energy restriction during late gestation on the body condition score, bodyweight, and colostrum quality of fall calving cows, as well as their subsequentcalf performance. For this study, 48 multiparous Angus cows were used from theIowa State University-McNay Research and Demonstration Farm fall herd.
