“…Interestingly, despite the fact that metritis is associated with RP (Laven and Peters 1996, Bonneville-Hébert et al 2011), this latter puerperal disorder did not remain in the models as a factor associated with P/AI. In some studies the effect of metritis on P/AI has been more severe than in the present study, this could be due to different classifications given to metritis (LeBlanc et al 2002, Gautam et al 2009 and inaccuracy of data with observational retrospective studies, or due to multiple herds and technicians involved. In the present study, data did not suffer from such lack of precision because a single herd was used and veterinarians in charge of diagnosing and treating this disease used the same therapy to treat this periparturient disorder.…”

ABSTRACT. The aim of this study was to determine the association among periparturient events such as mastitis, lameness (infectious and non-infectious) and ketosis and the reproductive performance of high producing Holstein cows in a hot environment. The health status and reproductive data variables were recorded from 6,566 completed lactations in a large dairy operation. A logistic regression model with the stepwise procedure was used, considering the occurrence of the health problems during the pre-breeding period as fixed effect risk factors and reproductive variables as dependent variables. Pregnancy rate of cows contracting clinical mastitis (CM) around the period of first inseminations was five percentage points lower than cows without this disease. Cows with CM shortly before or after the first service had twice the risk of requiring more than three services per pregnancy than cows with healthy udders. Cows experiencing abortion, laminitis or metritis were two times more likely to require >3 services per pregnancy than cows not experiencing these reproductive disorders. Cows experiencing lameness, mastitis and metritis presented a significantly longer interval between calving and pregnancy compared to healthy cows. Ketosis and lameness increased the odds of a cow of being inseminated for the first time after 70 days in milk. In conclusion, these results suggest that abortion, ketosis, CM, retained placenta (RP), metritis, and lameness are associated with decreased reproductive performance in high producing Holstein cows subjected to thermal stress.

“…Cows with no detectable signs of endometritis were sampled for uterine cytology (n=65). Cows in their first month postpartum were not used because uterine involution might not have finished (Gautam et al, 2009) and then, a high percentage of polymorphonuclear neutrophil (PMN) in the uterine cytology would be a normal finding.…”

The aim of this study was to evaluate the influence of subclinical endometritis (SE) on the reproductive performance of dairy cows. Ninety-four dairy cows of parity 1 to 8, distributed in 25 herds, were examined once between 30 and 45 days in milk using transrectal palpation, vaginoscopy and ultrasonography. A cytological sample of the endometrium was taken only from cows with an apparent healthy uterus (n=65). Serum glucose, total cholesterol, triglycerides, non-esterified fatty acids, β-hydroxybutyrate, total proteins, albumin, urea and hepatic enzymes were analyzed. Reproductive indexes were recorded during the next 11 months. Endometrial cytology was considered indicative of SE if percentage of polymorphonuclear neutrophils was superior to 5% of all cells present in the smear, except erythrocytes. Results indicated that 14.9% of the cows sampled for uterine cytology had SE, and that healthy cows become pregnant significantly before than those with SE (hazard ratio=2.35; 95% confidece interval: 1.05-5.3). From all the metabolic and productive variables analyzed, only triglycerides affected negatively to reproduction; serum albumin concentration, body condition score and milk production had positive effects on the reproductive performance. In conclusion, our results indicate that SE has a negative impact on reproductive performance and uterine cytology is necessary to diagnose it since almost 15% of the affected animals were not detected by other diagnosis methods.Additional key words: subclinical endometritis; dairy cattle; ultrasound; endometrial cytology.

The aim of this study was to isolate and identify uterine microorganisms in postpartum cows and to observe the occurrence of uterine infection in crossbred and local cows. One hundred and nine samples, from both crossbred and local dairy cows were collected from Chittagong area. They were inseminated artificially (n=89) and naturally (n=20). Samples were collected at least 3 months after calving. Among the selected cows, 33 had different reproductive diseases and the rest were from apparently healthy cows. The crossbred dairy cows were more susceptible to reproductive diseases (19.27%) than the local ones. Uterine infection was higher (52%) in cows inseminated artificially than that of natural ones (21.21%). Nineteen different types of bacteria were isolated from both diseased and healthy animals, except Clostridium spp and Nocardia spp which were not found in diseased animal. Likewise, Bacillus spp and Salmonella spp were absent in healthy animals. Most prevalent bacteria in diseased animal were Staphylococcus spp and Streptococcus spp found in 33% and 27.3% of the cases respectively. In non-diseased cases, the highest number of samples was positive for Bacteroied spp (13.2%) followed by Streptococcus spp (10.4%). On average, the highest number of bacterial population was isolated from diseased samples and most of those bacteria are pathogenic.
