Effects of two estradiol esters (benzoate and cypionate) on the induction of synchronized ovulations in Bos indicus cows submitted to a timed artificial insemination protocol
(Theriogenology, 2012-08-01) [Artigo]
The effects of estradiol benzoate (EB) and estradiol cypionate (EC) on induction of ovulation after a synchronized LH surge and on fertility of Bos indicus females submitted to timed AI (TAI) were evaluated. In Experiment ...
Anti-Mullerian hormone (AMH) as a predictor of antral follicle population in heifers
(Animal Reproduction, 2018-01-01) [Artigo]
Antral follicular population (AFP) and anti-Mullerian hormone (AMH) concentration are strongly associated. Thus, analyzing AMH concentration is a reliable method to predict animals with high AFP, an important feature to ...
Characterizing emergence and divergence in the first follicular wave in a tropically adapted Bos taurus breed
(Theriogenology, 2017-01-15) [Artigo]
Tropically adapted Bos taurus breeds are descended from the cattle which were brought from the Iberian Peninsula to Latin America by the colonizers and which adapted over time to local conditions. These breeds have become ...
Changes in luteinizing hormone secretion after estradiol treatment in prepubertal Nelore heifers
(Canadian Journal of Veterinary Research = Revue Canadienne de Recherche Veterinaire, 2011-07-01) [Artigo]
Changes in luteinizing hormone (LH) secretion after 17 beta-estradiol (E-2) injection were evaluated during sexual maturation in 10 prepubertal Nelore heifers. Heifers were divided into 2 groups: intact (I) and ovariectomized ...
High precision and selectivity for quantitation of enrofloxacin and ciprofloxacin in five chicken tissues using solid phase extraction and ESI LC-MS/MS for application in monitoring residues
(Analytical Methods, 2015-01-01) [Artigo]
Fluoroquinolones (FQs) are synthetic antimicrobials commonly used in intensive poultry farming to treat chronic respiratory disease, colibacillosis, and fowl cholera. As these drugs are also important in treating infections ...
Manifestation of estrous behavior and subsequent progesterone concentration at timed-embryo transfer in cattle are positively associated with pregnancy success of recipients
(Animal Reproduction Science, 2014-12-30) [Artigo]
Plasma estradiol and progesterone (P4) concentrations during the peri-ovulatory period are positively correlated with pregnancy success in cattle. The aims of this study were to assess the effects of estrus occurrence and ...
