Changes in Cytokine Profiles in Response to Ergovaline Exposure in Slick vs. Normal Hair Coat in Beef Heifers.
Brown, A. R., Haimon, M. K. L., Poole, R., Poore, M. H., & Poole, D. H. (2020, November). JOURNAL OF ANIMAL SCIENCE, Vol. 98, pp. 40–40.
TL;DR:
In contrast to previous data, exposure to ergovaline via endophyte-infected fescue, did not induce an innate immune response, and cytokine concentrations were elevated in heifers with the slick hair genotype.

In Utero Exposure of Ergot Alkaloids does not Impact Heifer Growth and Reproductive Performance.
Haimon, M. K. L., Brown, A. R., Poore, M. H., & Poole, D. H. (2020, November). JOURNAL OF ANIMAL SCIENCE, Vol. 98, pp. 44–44.
TL;DR:
While consumption of EI fescue during gestation impacts cow performance and onset of puberty in heifers, it has minimal effect on heifer growth and reproductive development and performance.

2019 journal article
Effects of endophyte-infected tall fescue seed and protein supplementation on stocker steers: II. Adaptive and innate immune function
Journal of Animal Science, 97(10), 4160–4170.
author keywords: beef steers; ergovaline; immunity; vaccination
MeSH headings : Animal Feed / analysis; Animals; Cattle / immunology; Dietary Supplements / analysis; Endophytes / physiology; Ergotamines / pharmacology; Festuca / chemistry; Festuca / microbiology; Immunity, Innate; Male; Plant Poisoning / veterinary; Vaccines / immunology
TL;DR:
Steers exposed to ergovaline have an increase in pro- and anti-inflammatory cytokines and supplemental CP had minimal impact to mitigate this response, however, in the current study exposure to ergovine had little to no effect on adaptive immunity and response to vaccination.

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.
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.
