OXIDANT/ANTIOXIDANT STATE IN REPEAT BREEDER COWS
Journal of Applied Biological SciencesIn this study, oxidant and antioxidant status in pregnant and repeat breeder (RB) cows were evaluated. For this purpose, approximately 10 mL of blood was taken into Li-Heparin tubes from the V. jugularis of a total of 68 Holstein breed cows, consisting of two groups: pregnant (n=34) and repeat breeder (n=34), less than 10 years old, inseminated 3 or ...

Repeat Breeder Syndrome Therapies in Dairy Cows: A Review
Reproduction in Domestic AnimalsABSTRACTRepeat breeder (RB) cows are clinically healthy animals with regular oestrous cycles that do not become pregnant after three or more services. This syndrome has an incidence ranging between 10.1% and 24%. Repeat breeder syndrome (RBS) in dairy cows leads to economic losses to dairy farmers by increasing the calving interval and consequently ...

Ovarian follicular dynamics in repeat breeder cow: ultrasonography and progesterone level [PDF]
, 2004 The aim of this study was to examine follicular development patterns in eighteen repeat breeder cows through spontaneous oestrus cycles. Ovarian ultrasonographic examinations over 32 days after artificial insemination revealed that two follicular waves ...

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.ABSTRACT Animals with seasonal reproductive cycles, as the Roe deer (Capreolus capreolus), have developed mechanisms to synchronize reproduction with the environmental cycle in order to optimize reproductive success through melatonin. Angiogenesis and oxidative stress are key processes in spermatogenesis, contributing to testicular remodeling and ...
