Abstract

Suckling post-partum cows treated for oestrous synchronization exhibited oestrus and became pregnant earlier in the mating period than untreated cows. Combined treatment with a progesterone-releasing device and prostaglandin F synchronized oestrus in a greater proportion of the cows than treatment with prostaglandin Fα alone (P < 0·01). The combined treatment appeared to induce ovarian activity in post-partum anoestrous cows that were approaching their first ovulation.
