Postpartum uterine diseases in dairy cows
Uterine diseases in dairy cows can be classified as puerperal metritis, clinical metritis, clinical endometritis, and subclinical endometritis. These diseases are highly prevalent (affect between 20 and 30% of dairy cows) in high producing dairy cows and have been associated with decreased pregnancy per artificial insemination (AI), extended interval to pregnancy, increased culling, and economi...
متن کاملEpidemiology of reproductive performance in dairy cows.
The objectives of this presentation are to review results of our previous and on-going research with respect to the risk factors and consequences of poor reproductive performance in dairy cows, and to develop an economic framework to optimize decisions related to dairy cow reproductive performance. To make profitable breeding and replacement decisions, the farmer must account for factors includ...
متن کاملInteractions between negative energy balance, metabolic diseases, uterine health and immune response in transition dairy cows.
The biological cycles of milk production and reproduction determine dairying profitability thus making management decisions dynamic and time-dependent. Diseases also negatively impact on net earnings of a dairy enterprise. Transition cows in particular face the challenge of negative energy balance (NEB) and/or disproportional energy metabolism (fatty liver, ketosis, subacute, acute ruminal acid...
متن کاملAssociation of Neospora caninum with reproductive performance in dairy cows: A prospective study from Iran
There is no prospective study from Iran to estimate the direct risk of Neospora caninum for pregnancy loss or reproductive factors. In addition, there is no report in the literature concerning the association of N. caninum with dystocia and sex of calves. Therefore, this study was conducted on a group of dairy cows in a large intensive production system during 2011 to 2013 in ...
متن کاملThe effect of metritis and subclinical hypocalcemia on uterine involution in dairy cows evaluated by sonomicrometry
The objective of this study was to examine the effects of metritis and subclinical hypocalcemia on reduction of uterine size in dairy cows using ultrasonography and sonomicrometry. Four piezoelectric crystals were implanted via laparotomy into the myometrium of the pregnant uterine horn of 12 pluriparous Holstein Friesian cows 3 weeks before the calculated calving date. Sonometric measurements ...
