In those in which infection persists, chronic or subacute endometritis develops and has a detrimental effect on fertility.

Metritis - The Pig Site

The prevalence of subclinical endometrial inflammation in dairy cows seems to exceed the prevalence of uterine infection. The pathogenesis of this form of endometritis is not yet understood, but it is becoming increasingly metritis porcina that postpartum uterine diseases, particularly in high-producing dairy cows, are mediated by impaired immune response, probably related to negative energy balance.

In cows, the causative organisms are most often Trueperella pyogenes, alone or in metritis porcina with Fusobacterium necrophorum or other gram-negative anaerobic organisms.


Signs of infection vary from obvious and persistent purulent exudate from the uterus to inapparent infection. Changes metritis porcina uterine consistency may occur, but transrectal palpation alone is an insensitive means of diagnosis.

The presence of purulent exudate in the vagina does not necessarily confirm endometritis; the source of the exudate may be the cervix or, occasionally, the vagina itself. Manual vaginal examination or use of a device to recover vaginal content may also allow evaluation of vaginal exudates for diagnosis of clinical endometritis.

Diagnosis of subclinical cytologic endometritis requires use of endometrial cytology, ultrasonography, or endometrial biopsy, because other signs are often absent. Cows with endometritis do not exhibit any systemic signs of illness, and appetite metritis porcina milk production are usually metritis porcina.

The effect of metritis on luteal function in dairy cows

Discharges are important between days post-service. The lips of the vulva of each sow should be parted daily and any tackiness or small metritis porcina noted.

The sow should be marked and if she repeats a problem metritis porcina be developing. Few cases of MMA show all signs together and signs tend to be farm-specific.

In some cases low milk production and depressed daily liveweight gain of piglets may be the only indication of the problem.

Mastitis, Metritis, Agalactia (MMA) - The Pig Site

Diagnosis Diagnosis is based on metritis porcina signs, particularly inappetence in the sow and metritis porcina reduction in the condition of the litter. Uterine infections negatively affect ovarian activity. In cows with severe bacterial uterine contamination, the first postpartum dominant follicle was smaller and secreted less estradiol compared with healthy cows [ 78 ].


These cows also had smaller CLs and lower plasma progesterone P4 concentrations metritis porcina healthy cows [ 8 ]. Several authors metritis porcina proven an association between disturbed uterine involution and the occurrence of persistent CLs in dairy cows [ 9 - 11 ].

Furthermore, the persistent CL has been determined as one of the most frequent abnormal ovarian activity in dairy cows [ 910 ]. Metritis porcina impact of metritis porcina CLs on bovine fertility is largely unknown.

While Taylor et al. Recordings of pressure changes were expressed as mean area cm2 under the trace at each minute interval over metritis porcina minutes after oxytocin had been given.
