Blood biochemical profile of Sudanese crossbred repeat breeder cows [PDF]
El reproductor repetido (RB) es una vaca que no logra concebir a partir de tres o más inseminaciones sucesivas, pero con celo normal y ausencia de anomalías clínicas detectables. Es uno de los principales problemas en la producción láctea. En el presente estudio, se examinó la bioquímica plasmática de las vacas RB cruzadas sudanesas.

Scopolamine administration in repeat breeder cows on the day of heat
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

Histological Observation of the Endometrium in Repeat Breeder Cows.
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 ...

Polyunsaturated fatty acids influence offspring sex ratio in cows [PDF]
Dietary polyunsaturated fatty acids (PUFAs) can influence fertility in farm animals. Some evidence in mice and sheep have suggested that PUFAs may influence offspring sex ratio, which may have significant value for cattle production.

Preovulatory follicle characteristics and oocyte competence in repeat breeder dairy cows [PDF]
The varied and elusive etiology of repeat breeding (RB) in dairy cows necessitates evaluation of oocytes and follicles, which have not previously been assessed together. Accordingly, we evaluated characteristics of preovulatory follicles and the competence of oocytes in control (CTL) and RB cows.

Clinical Approach to the Repeat Breeder Cow Syndrome [PDF]
Dairy cattle production requires great intensification, which has been demonstrated to affect negatively on the reproduction. One calf by cow and year is the reproductive objective in these animals. It means that cows must get pregnant after AI, maintain the pregnancy, have parturition after 270 days approx., and wait for a period of 40-50 days to be ...
