Effects of exogenous prostaglandin-F2α (PGF2α) on pregnancy status in white-tailed deer
Abstract 10.1002/zoo.1430130405.abs As part of a study to develop contraceptive methods for white-tailed deer (Odocoileus virginianus), it was necessary to terminate pregnancies in some does. The abortifacient chosen was PGF2α. At 76 days or less of gestation, PGF2α administration (10 mg i.m.) did not decrease mean serum progesterone (P) concentrations, and only one doe of […]

Cattle often eat pine needles, and pregnant cattle that are allowed to eat pine needles will abort, resulting in dead or premature calves, retained placentas, and uterine infections.

Evaluation of Reproduction and Raising Offspring in a Nursery-Reared SPF Baboon (Papio hamadryas anubis) Colony

Because the founding generations were nursery-reared until 2 years of age, it was suspected that the SPF baboons would exhibit increased reproductive challenges as adults. Mothering behavior was of interest, because SPF females were not exposed […]
