Induction of Estrus in Lactating Sows with Equine Gonadotropin

H. H. Cole and E. H. Hughes

University of California1

Abstract

Forty-two sows were injected with approximately 1000 I.U. equine gonadotropin during lactation to induce estrus. Sows which were injected in early lactation (1 to 38 days) did not manifest estrus regularly but 26 of 27 sows injected between the thirty-ninth and sixty-eighth days of lactation came into heat three to seven days following treatment. All of these animals were bred. Twenty of 23, on which information was available, became pregnant during this induced estrus. The practical aspects of the problem are briefly discussed.
