Cystic Ovarian Disease and Thyroid Hormones in Dairy Cattle
Ovarian cysts reduce reproductive efficiency on almost every dairy farm in the World. Cystic ovarian disease in cows is usually seen in the first two months post calving. Ovarian cysts are characterized as structures greater than 2.5cm in diameter remaining on an ovary for more than 10 days. Cysts are simply filled with fluid enclosed by membranes like grapes. Since ovarian cysts reduce reprodu...
متن کاملInfluence of ovarian hormones on urogenital infection.
Numerous studies have examined the influence of hormones on infectious diseases and there is now a wealth of data relating to the more specific effect of the sex hormones, oestrogen and progesterone, on urogenital infections. The interaction between these hormones and the immune system is complex and the variation of hormonal effect between species further complicates the true picture as relate...

Usually there is some evidence of at least minor dystocia. The soft tissues appear to have been stretched beyond their limits of immediate and adequate recovery. There is often, but not always, some loss o...
متن کاملCharacterization of single nucleotide polymorphism in the 5'-untranslated region (5'-UTR) of Lactoferrin gene and its association with reproductive parameters and uterine infection in dairy cattle
Uterine infection is one of the reproductive diseases that can have disturbing postpartum uterine health in cattle. Therefore, identification of resistant genotypes to uterine infection is important. Lactoferrin (LF) is one of the major antimicrobial compounds in the normal uterine discharges of cows. We hypothesized that allelic diversity in LF gene may contribute to susceptibility or resistan...
متن کاملManipulation of ovarian and uterine function to increase conception rates in cattle
In cattle, embryonic and fetal losses are the major causes of reproductive failure. Losses associated with failure in the process of maternal recognition of pregnancy can amount to as much as 30%. Successful establishment of pregnancy depends on a delicate balance between luteolytic mechanisms inherent to the endometrium at the end of diestrus and antiluteolytic mechanisms, orchestrated by the ...
