The prevalence of subclinical endometritis and intrauterine infections in repeat breeder cows
(Elsevier Science Inc, 2015-05)
The objectives of this study were to assess the prevalence of subclinical endometritis and the presence of common uterine pathogens in repeat breeder cows. A total of 121 cows with three or more consecutive artificial ...
Short communication: Repeat breeder cows with fluid in the uterine lumen had poorer fertility
(American Dairy Science Association, 2017-04)
The objective of the present study was to test the association between the presence of fluid in uterine lumen and the fertility of repeat breeder cows (RBC). Grazing Holstein cows that were clinically normal and were not ...
Endometrial expression of key genes related to fertility in repeat breeder and non-repeat breeder cows
(Wiley Blackwell Publishing, Inc, 2020-11)
The aim of the present study was to compare the endometrial gene expression of epidermal growth factor receptor (EGFR), nodal growth differentiation factor (NODAL), prostaglandin-endoperoxide synthase 2 (PTGS2), oestrogen ...
Effect of fixed-time embryo transfer on reproductive efficiency in high-producing repeat-breeder Holstein cows
(Amsterdam, 2010)
The aim of the present study was to compare a synchronization of time of ovulation protocol for fixed-timed embryo transfer (FTET) with the usual administration of a single dose of prostaglandin associated with detection ...
The low fertility of repeat-breeder cows during summer heat stress is related to a low oocyte competence to develop into blastocysts
(ELSEVIER SCIENCE INC, 2011)
It was hypothesized the lower fertility of repeat-breeder (RB) Holstein cows is associated with oocyte quality and this negative effect is enhanced during summer heat stress (HS). During the summer and the winter, heifers ...
