Creator:: Tan, Taralyn
Abstract:: Approximately five to eight percent of domestic rams demonstrate a sexual attraction towards other rams, directing no sexual behaviors towards estrous ewes. It has been observed that these male-oriented rams (MORs) have a greater abundance of prolactin mRNA than female-oriented rams in the medial preoptic area of the anterior hypothalamus...

Creator:: Habeeb, Hayder
Abstract:: Sheep are seasonally polyestrus, which means they do exhibit estrus and ovulation during the short daylight (breeding season) and do not during the long daylight (nonbreeding season).

Corpora lutea were not observed in...

Abstract:: Our objectives were to determine 1) the concentration of prostaglandin F2α (PGF2α) in whole and extended bovine semen, 2) if concentrations of prostaglandins in extended bovine semen are correlated to fertility, and 3) if PGF2α administered at the time of artificial insemination would improve conception rate. Concentration of PGF2α tended...

Creator:: Lutterschmidt, Deborah I.
Abstract:: Most vertebrates exhibit seasonality in many life history traits. Such seasonal rhythms are temporally organized via the transduction of environmental cues (e.g., photoperiod, temperature) into appropriate endocrine signals. However, among ectothermic vertebrates that undergo continuous winter dormancy, temperature is the only environmental cue available for synchronizing seasonal rhythms. Most intriguing...
