Abstract
Twelve Israeli-Friesian heifers and cows were treated for estrus synchronization with intravaginal sponges impregnated with 250 mg. medroxyprogesterone acetate (MAP) for a period of 14 days. All sponges were retained throughout the treatment period and 100% of the animals came into estrus 3–7 days after sponge removal. Conception rate from insemination at the synchronized estrus was 60%. It is concluded that further investigation is justified regarding the value of progestin-impregnated sponges as a practical means of estrus synchronization in cattle.
