The effect of medroxyprogesterone acetate on pregnancy rates in reindeer calves (Rangifer tarandus) / Erik Ropstad, Gaute Helland, Helge Hansen, Dag Lenvik, Eva Tangen Solberg.

Title: The effect of medroxyprogesterone acetate on pregnancy rates in reindeer calves (Rangifer tarandus) / Erik Ropstad, Gaute Helland, Helge Hansen, Dag Lenvik, Eva Tangen Solberg.

Date: 1993.
In: Rangifer. (1993.), Vol. 13(3) (1993)
Abstract: In September 1990 69 calves with minimum body weight of 46 kg were separated into two groups, one treated with single injection of medroxyprogesterone acetate, the other as control. Blood samples were collected for progesterone analysis in December 1990 and 1991. Udders were palpated in July and September 1990. Treated animals had significantly lower plasma progesterone levels in 1990. Pregnancy rate as found by udder palpation was 17% for treated animals, 48% for controls. All animals found to be pregnant had high progesterone the following winter. More than 50% of pregnant females lost their calves during summer.
