Leptin receptor expression and its change in association with the normalization of EGF profile after seminal plasma treatment in repeat breeder dairy cows

open access: yesThe Journal of Reproduction and Development, 2022
Factors associated with high milk production levels have been linked to alterations in the endometrial epidermal growth factor (EGF) profile, a cause of reduced fertility in dairy cows.

Current Insights in the Repeat Breeder Cow Syndrome

open access: yesAnimals, 2023
Cows can have difficulties becoming pregnant, and in certain cases, these reproductive failures do not have an evident cause. Furthermore, when these failures are repeated three or more times with estrous cycles of normal duration and in the absence of evident clinical signs, it is considered repeat breeder cow (RBC) syndrome.

Scopolamine administration in repeat breeder cows on the day of heat

open access: yesTheriogenology, 2023
Scopolamine is a parasympatholytic drug that can modulate uterine contractile activity. Based on the hypothesis that deficiency in uterine contractility is a cause of Repeat Breeder (RB) syndrome in cows, this study aimed to evaluate the efficacy of scopolamine administration in RB cows, on the day of heat, in increasing conception rates. Forty RB cows

Comparison of serum leptin, glucose, total cholesterol and total protein levels in fertile and repeat breeder cows

open access: yesRevista Brasileira de Zootecnia, 2014
In the present study we measured serum glucose, leptin, total cholesterol and total protein concentrations in repeat breeder cows and compared them with fertile cows. For this aim, 20 repeat breeder cows and 20 fertile cows were used as material.

Histological Observation of the Endometrium in Repeat Breeder Cows.

open access: yesJournal of Veterinary Medical Science, 1995
The endometrium plays an important role during attachment and implantation of embryos. Using histological techniques, we evaluated the morphological changes of the endometrium in repeat breeder cows. Endometrial biopsy specimens were obtained from 5 Holstein repeat breeder cows, 5 normally cyclic Holstein cows and 5 normally cyclic Holstein heifers on ...
