The effects of fungal-infected fescue on hormonal secretion and ovarian development in the beef heifer


Journal of Animal Science 67(Suppl. 2): 58
The effects of fungal-infected fescue on hormonal secretion and ovarian development in the beef heifer
Nineteen prepubertal beef heifers were allotted to fescue-based pastures containing fungal endophyte (Acremonium coenophialum) levels of 0-75%. Experiments were conducted to determine whether hormonal secretion and ovarian development were affected. GnRH challenges were effected when the heifers were 3 and 5 months of age. Blood was collected at 0, 1 and 2 h post-injection and assayed for LH, FSH and prolactin (PRL).
