Supranutritional Selenium-Yeast Supplementation of Beef Cows during the Last Trimester of Pregnancy Results in Higher Whole-Blood Selenium Concentrations in Their Calves at Weaning, but Not Enough to Improve Nasal Microbial Diversity

Autor: Jean A. Hall, Anitha Isaiah, Ened R.L. McNett, Joseph J. Klopfenstein, T. Zane Davis, Jan S. Suchodolski, Gerd Bobe

Publikováno v: Animals, Vol 12, Iss 11, p 1360 (2022)

We previously reported that feeding Se-biofortified alfalfa hay to weaned beef calves in a preconditioning program increases whole-blood Se (WB-Se) concentrations and nasal microbiome abundance and diversity during the preconditioning period, decreas

The comparative toxicity of Isocoma species in calves

Autor: T. Zane Davis, Benedict T. Green, Bryan L. Stegelmeier, Stephen T. Lee

Publikováno v: Toxicon: X, Vol 5, Iss , Pp - (2020)

Isocoma pluriflora and Isocoma acradenia are toxic plants that contain the putative toxin tremetone. It is common for I. pluriflora to poison livestock in the southwestern United States. I. acradenia has been suspected of poisoning livestock but its

Microsomal activation, and SH-SY5Y cell toxicity studies of tremetone and 6-hydroxytremetone isolated from rayless goldenrod (Isocoma pluriflora) and white snakeroot (Agertina altissima), respectively

Autor: Benedict T. Green, Stephen T. Lee, T. Zane Davis, Kevin D. Welch

Publikováno v: Toxicon: X, Vol 5, Iss , Pp - (2020)

This research compared the cytotoxic actions of the benzofuran ketone, tremetone in B16 murine melanoma cells to SH-SY5Y human neuroblastoma cells with an MTT assay. Tremetone was not cytotoxic in B16 cells. In SH-SY5Y cells, concentration-dependent

Feeding selenium-biofortified alfalfa hay during the preconditioning period improves growth, carcass weight, and nasal microbial diversity of beef calves.

Autor: Jean A Hall, Anitha Isaiah, Gerd Bobe, Charles T Estill, Janell K Bishop-Stewart, T Zane Davis, Jan S Suchodolski, Gene J Pirelli

Publikováno v: PLoS ONE, Vol 15, Iss 12, p e0242771 (2020)

We previously reported that feeding Se-biofortified alfalfa hay to weaned beef calves in a preconditioning program decreases morbidity and mortality during the feedlot period. To understand the mode of action by which supranutritional Se supplementat
