The effects of feeding white clover pellets and red clover hay on teat length, plasma gonadotrophins and pituitary function in wethers

  • N. Saba (a1), A. M. Symons (a1) and Hilary M. Drane (a1)


Feeding of white clover or red clover oestrogenic diets to wethers produced increases in teat length but did not affect the basal plasma luteinizing hormone levels or pituitary sensitivity to luteinizing hormone-releasing hormone.
