No. of bitstreams: 0 Previous issue date: 2013-12-01; The aim of the present study was to evaluate the effects of type of norgestomet auricular implant (new-N or previously used during 5 days-U), season of the year (summer-S and winter-W), and parity (12 heifers-H and 23 cows-C) on synchronization of follicular wave emergence in buffaloes. For this purpose...

No. of bitstreams: 0 Previous issue date: 2013-12-01; The aim of the present study was to evaluate the effects of season of the year (summer and winter) and parity (heifers and cows) on oocyte quality and number in buffaloes. For this purpose, 71 buffaloes had follicular wave emergence synchronized before OPU. OPU of all follicles ≥ 2mm was done 5 days aft...
The objective of this study was to evaluate the impact of using technology to reduce the age at first calving (AFC; from 48 to 24 months) and increase the weaning rate (WR; from 60% to 80%) in beef herds. The need for pasture area (hectares) and the CO2 equivalent emissions (CO2eq.) of animals present in the production system were analyzed. Data from a livestock breeding system were used to produce 400 male cal...

No. of bitstreams: 0 Previous issue date: 2013-12-01; Buffaloes and bovines are polyestrous and seasonal or annual livestock, respectively, that show reduced fertility during heat stress. To investigate whether reduced fertility is related to oocyte competence in both species, immature oocytes from buffalo and bovine heifers were collected during winter an...
