No. of bitstreams: 0 Previous issue date: 2021-01-01; Background: Progesterone (P4) is essential for embryonic development and maintenance of pregnancy when deficiency causes early embryonic loss. In this study, we investigated the ability of hormonal supplementation to improve the fertility of Nellore females subjected to fixed-time artificial inseminatio...
An approach to rescue the fertility of stallions with a high level of hemospermia
Andrade Junior, Luiz Roberto P. [UNESP]; Segabinazzi, Lorenzo G. T. M. [UNESP]; Oliveira, Sidnei N. [UNESP]; Dell'Aqua, José Antonio [UNESP]Made available in DSpace on 2020-12-12T02:47:11Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-09-01; A high amount of blood and not the mere presence of blood in equine semen impacts fertility. The aim of this study was to develop an approach to rescue the fertility of stallions with high hemospermia levels. Semen from 15 stallions was divided into four experimental groups: (a) Control—pure raw semen, ...
