The Effects Of Storage Temperature On The Bovine Nasal Microbiome, Hunter Usdrowski
The Effects Of Storage Temperature On The Bovine Nasal Microbiome, Hunter Usdrowski
Animal Science Undergraduate Honors Theses
Bovine respiratory disease (BRD) is one of the largest economic burdens facing United States beef producer’s modern day. The complexity in the onset and development of this multifactorial disease necessitates further insights into its functions to alleviate the tremendous consequences it generates for producers. The respiratory microbiome and their metabolomics play an important role to maintain health and predict BRD. However, due to low biomass, new technology is needed to increase the microbial concentration for omics (e.g. metatranscriptomics) research. In this study, a novel self-enrichment storage technique on the bovine nasal microbiome was performed and compared to a traditional nasal …
Effects Of Toxic Fescue Exposure On Vaginal Microbial Communities Of Crossbred Beef Cows, Abby Ratton
Effects Of Toxic Fescue Exposure On Vaginal Microbial Communities Of Crossbred Beef Cows, Abby Ratton
Animal Science Undergraduate Honors Theses
The consumption of toxic fescue by beef cattle results in several adverse physiological effects such as reduced reproductive success, severe vasoconstriction resulting in hoof sloughing, low body condition scores, hyperthermia, decreased prolactin levels, and reduced hair shedding. The purpose of this study is to characterize bacterial community of the reproductive tract as a potential predictor for toxin exposure. One-hundred fall-calving crossbred cows were allocated to graze Toxic (Toxic: n=50) or Novel (Novel: n= 50) fescue pastures for five months (March-August). Treatments were blocked by sire breed (Charolais or Hereford) and by parity (first, second, third). Animals rotated pastures biweekly and …
