The aims of the present study were to evaluate the morphometry of corpus luteum (CL) and progesterone (P4) plasma concentration of 86 buffaloes (33 pregnant and 53 non-pregnant) and 95 cows (36 pregnant and 59 non-pregnant) ...
Progesterone-based estrous synchronization protocols in non-suckled and suckled primiparous Bos indicus beef cows
(Elsevier B.V., 2010-05-01)
In Experiment 1, effects of an intravaginal progesterone insert (CIDR) for synchronization of estrus in non-suckled cycling primiparous Bos indicus beef cows were evaluated. Cows received either no treatment (Control), ...
