Peres, R. F.G. [UNESP]; Cooke, R. F.; Dias, H. [UNESP]; Keisler, D. H.; Pohler, K. G.; Vasconcelos, J. L.M. [UNESP]Made available in DSpace on 2021-06-25T10:23:47Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-03-01; Two experiments compared body parameters and serum concentrations of GH, IGF-I, and leptin in Bos indicus females based on their pregnancy status to fixed-time artificial insemination (FTAI). In Exp. 1, 226 nulliparous heifers were assigned to a puberty induction protocol (d -35 to d -23), followed by a...

No. of bitstreams: 0 Previous issue date: 2019-01-01; The bovine appeasing substance (BAS) is expected to have calming effects in cattle experiencing stressful situations. Therefore, this study investigated the impacts of BAS administration during two of the most stressful events within beef production systems: weaning and feedlot entry. In experiment 1, 1...

Cooke, R. F.; Pohler, K. G.; Vasconcelos, J. L.M. [UNESP]; Cerri, R. L.A.Made available in DSpace on 2019-10-06T15:42:32Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; Expression of estrus (EST) near the time of fixed-time artificial insemination (FTAI) increases pregnancy success in beef females. This outcome has been associated with improved pregnancy establishment and maintenance, although research is still warranted to validate this theory. Hence, this experiment ...
Evaluation of beef cow and calf separation systems to improve reproductive perf...
Martins, P. G. M. A.; Arthington, J. D.; Cooke, R. F.; Lamb, C. G.; Araújo, D. B.; Torres, C. A. A.; Guimarães, J. D.; Mancio, A. B.A two-year study was conducted with the objective to compare the effects of a traditional 48-h calf withdrawal to early-weaning and repeated 48-h calf withdrawals on postpartum interval and measures of performance of first-calf cows. A total of 112 primiparous, Brahman×British cow–calf pairs were randomly allotted to three treatments over two consecutive years: early weaning (EW; permanent cow and calf separati...
