Ova tranfers in sheep and rabbits : studies on material influences and irradiation damage

Creator:: Hunt, William Lynn
Abstract:: The first study utilized ova transfer in sheep and involved hormonal treatments for synchronization of estrus and superovulation in an investigation of crossbred maternal influences on inbred and linecross lambs. Synchronization of estrus in ewes was achieved effectively with either oral progestogen, 6 α-methyl-17α-hydroxy-progesterone acetate (60 mg./ewe/day), or intramuscular injections...

Gonadotropin releasing hormone-induced alteration of corpus luteum function in beef heifers

Creator:: Rodger, Lynn Dian
Abstract:: Two experiments were conducted to evaluate the effects of gonadotropin releasing hormone (GnRH) on the function of the bovine corpus luteum during the estrous cycle. In Experiment 1, 10 heifers were assigned randomly into two groups with each heifer serving as her own control. Heifers in Group I (n=5) were...

Urinary estrogens and progestins in pregnant pony mares

Creator:: Riad, Mohamed Tarek
Abstract:: Urinary steroids have been studied during early and late pregnancy in domestic horses or sporadic samples at various stages of pregnancy in wild equidae. In our studies, urinary estrone sulfate (E1S) and pregnanediol glucuronide (PdG) were monitored throughout pregnancy in six pony mares by enzyme immunoassay (EIA). Both hormones were...

Reproductive characteristics of pregnant mares passively immunized against equine chorionic gonadotropin

Creator:: Shore, Maria Dawn
Abstract:: Two experiments were conducted to examine the effects of passive immunization of pregnant mares with a monoclonal antibody [MAb, 518B7, antibovine βLH which crossreacts with equine chorionic gonadotropin (eCG)] on subsequent reproductive characteristics and changes in plasma concentrations of hormones. In Exp.1 control mares (C, n=3) were not treated. Another...
