Evaluation of Resistance to Fescue Toxicosis in Purebred Angus Cattle Utilizing Animal Performance and Cytokine Response

TOXINS, 12(12).

By: D. Poole n , K. Mayberry n, M. Newsome n, R. Poole  n, J. Galliou n, P. Khanal n, M. Poore n, N. Serao  n

author keywords: fescue toxicosis; genetic tolerance; cytokines; cow productivity
MeSH headings : Animal Feed / analysis; Animal Feed / toxicity; Animals; Behavior, Animal / drug effects; Behavior, Animal / physiology; Cattle; Cattle Diseases / chemically induced; Cattle Diseases / metabolism; Cattle Diseases / microbiology; Cytokines / metabolism; Ergot Alkaloids / analysis; Ergot Alkaloids / toxicity; Herbivory / drug effects; Herbivory / physiology; Poaceae / microbiology; Poaceae / toxicity
TL;DR: Findings from this study support the proposed fescue toxicosis selection method, could accurately distinguish between tolerant and susceptible animals based on the performance parameters in cattle chronically exposed to ergot alkaloids, and provides evidence to warrant additional analysis to examine the impact of ergotAlkaloids on immune responsiveness in cattle experiencing fescues toxicosis.

2019 article

Evaluation of cytokine response as an indicator of genetic resistance to fescue toxicosis in purebred Angus cattle.

Mayberry, K., Poole, R. K., Newsome, M. K. A., Khanal, P., Poore, M. H., Serao, N. V. L., & Poole, D. H. (2019, July). JOURNAL OF ANIMAL SCIENCE, Vol. 97, pp. 45–46.

By: K. Mayberry n, R. Poole  n, M. Newsome n, P. Khanal n, M. Poore n, N. Serao *, D. Poole n 

author keywords: fescue toxicosis; genetic tolerance; cytokines
TL;DR: Evaluating the cytokine response of cows deemed either tolerant or susceptible to endophyte-infected fescue found greater concentrations of GASP-1, VEGF-A, and IL-4 in tolerant compared to susceptible cattle may mitigate the detrimental effects of fescUE toxicosis, including suppressed PRL and vasoconstriction, leading to improved animal performance in a fescues environment.

2019 article

Long term impact of ergot alkaloids on fetal heifer development and subsequent growth and reproductive performance.

Jackson, M. K. L., Newsome, M. K. A., Brown, A. R., Poole, R. K., Dudley, H. B., Poore, M. H., & Poole, D. H. (2019, July). JOURNAL OF ANIMAL SCIENCE, Vol. 97, pp. 46–46.

By: M. Jackson n, M. Newsome n, A. Brown n, R. Poole  n, H. Dudley n, M. Poore n, D. Poole n 

author keywords: fetal programming; heifer development; fescue
TL;DR: While consumption of EI fescue impacts cow performance, calf birthweight, and ratio of cotyledon to placenta weight, it has minimal effect on postnatal growth and development through 10 mo of age, further studies are needed to determine the impact on heifer reproductive performance.

author keywords: fFixed timed AI; postpartum beef cows; corpus luteum
TL;DR: Incorporating a presynchronization program to ensure the presence of a functional CL at the start of a FTAI protocol may improve pregnancy success in postpartum beef cows. (via Semantic Scholar)
