Abstract Fescue toxicosis negatively impacts cattle productivity. Previous data from our laboratory has demonstrated that within a herd respond differently when grazing tall fescue, thus variation breed may provide genetic tolerance to the negative effects on performance. results in major cardiovascular system, it was hypothesized exposure ergot alkaloids pulmonary arterial pressure (PAP).
