Effects of Maternal Dietary Yeast Supplementation on Foal Growth and Microbial Diversity of the Hindgut in Quarter Horse Mares and Their Offspring
Bibliographic record
Abstract
Microbial populations in the hindgut of horses can be influenced by dietary yeast supplementation.Influencing the microbiome of the mares may have an effect on the gastrointestinal microflora of their foals and contribute to the colonization and development of their nave gastrointestinal microbial ecosystem which is important to the overall health and well-being of the foal.The objective of this study was to evaluate the effect of a maternal dietary live yeast supplement on the diversity of the gastrointestinal microflora in the hindgut of Quarter Horse mares and the growth and development of their offspring.In this study, eight Quarter Horse mares (14.5 7.5 yr) were randomly assigned to one of two treatment groups: yeast or control.All mares received a basal diet consisting of 0.5% BW of a 16% CP pelleted concentrate, with water and mixed grass hay ad libitum.Mares in the yeast treatment group were fed a targeted dose of 1 g (4.5 x 10 9 cfu)/45.4kg of BW per day of a live culture of Saccharomyces cerevisiae from d 250 of gestation to 90 d post-parturition.Mare fecal samples were collected monthly from d 250 of gestation to d 180 post-parturition.Foal fecal samples were collected within 2 hr of birth, at 12 and 24 hr after birth and monthly post-parturition until d 240.Fecal samples were pooled by production status, treatment and day.Pooled fecal samples were subjected to PCR to ascertain the presence or absence of Saccharomyces cerevisiae using supplementation of the maternal diet.Overall, supplementation of the maternal diet with live yeast did not impact foal growth but did influence the microbial profiles in the hindgut of mares and their offspring.v DEDICATION Dedicated to my Granny, Judy Lee Bryant vi ACKNOWLEGDEMENT I would like to first thank my family and friends who have supported me throughout this process.My parents, Doug and Becky Share, and my two sisters, Katie and Victoria, have been there when I need to have a complete meltdown and just vent my frustrations for a bit.My friends Penny, Masa and Corey have been irreplaceable during this time.Thanks for listening and giving me good advice on how to handle the stress that comes along with graduate school!I would also like to thank Devon.Thanks for the incredible pep talks and always taking the

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
