Synchronization of Estrus in Heifers
The Professional Animal Scientist, 2003 Numerous procedures have been developed to manipulate the estrous cycle of heifers to maximize the number that are in estrus during a short, predefined period with normal fertility-synchronized estrus. Early procedures consisted of synthetic progestins alone [melengestrol acetate; MGA® (Pharmacia and Upjohn Company, Kalamazoo, MI)], prostaglandin F2α ...

Detection of Estrus by Three Methods
Journal of Dairy Science, 1977 Estrus was detected by three methods in 88 postpartum Holstein cows housed in tie-stalls and allowed free activity 1 to 2 h daily in separate exercise lots. Cows in each of three groups were observed visually for standing estrus by herdsmen. Cows (31) in Group I were observed only visually and served as controls, cows (33) in Group II were fitted with ...

Aging Cell, EarlyView.Multi‐ciliated cells in the infundibulum and ampulla (INF/AMP) epithelium are vacuolated in aging. Unique cellular susceptibility of the INF/AMP epithelial population and aging‐associated decline in ovarian artery circulation, which supports the ovary and INF/AMP, contribute to this region‐specific vacuolation phenotype, as a consequence of a mildly ...
