Postpartum Ovarian Function of Dairy Cows in a Tropical Environment

Uterine and systemic inflammation influences ovarian follicular function in postpartum dairy cows

The objective of this study was to determine the effects of uterine and systemic inflammatory responses to uterine bacterial contamination at calving in dairy cows on the growth and ovulatory outcomes of the first dominant follicle postpartum. Ovulatory capability of the first dominant follicle postpartum was predicted in 53 multiparous cows by using a combination of follicle growth characteris...

Effects of dietary polyunsaturated fatty acids on ovarian function and prostaglandin secretion in lactating dairy cows

As lactating cows in severe negative energy balance have poor reproductive performance, the effect of dietary fat supplementation (fish oil, soybean oil) on PGFM secretion, ovarian function and blood metabolites is investigated. In this experiment, the effects of dietary polyunsaturated fatty acids on plasma metabolites, ovarian function and prostaglandin secretion of 20 primiparous Holstein co...

Treatment of Postpartum Metritis in Dairy Cows

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...
