“…Contrary to the previous reports by López-Gatius (16) and López-Gatius et al (17,18) of COD as a common disorder and a significant cause of reproductive failure in dairy cows in Spain, COD is in the fifth place as a cause of subfertility in cows from Central Croatia and has decreased 2-fold over a 5-year period. We speculate that the mentioned differences can be attributed to the breed and milk yield since studies in Spain included the high-producing Holstein-Friesian breed while our study included cows of the Simmental breed of dual purpose with lower milk production.…”

“…For the purpose of the study, cystic ovarian disease (COD) was diagnosed when 1 or more fluid-filled structures were found on ovaries unilaterally or bilaterally measuring more than 3 cm in diameter and persisting for 10 or more days with the absence of corpus luteum (13)(14)(15)(16)(17)(18). The diameter was estimated by transrectal palpation and measured using ultrasonography.…”

“…Although ovarian follicular dynamics in the postpartum dairy cow appear to be unaffected by a negative energy balance [23], estrus expression may be more sensitive to a decrease in body fat stores. In fact, inability to display estrus in normal cycling cows is one of the most common reproductive disorders associated with high milk production, as, for example, about 40% of cyclic cows do not show clear expression of estrus measured by pedometers [17,24].…”

Abstract. The aim of this study was to evaluate the effect of body weight (BW) change during the early postpartum period and BW on day 50 post partum on the subsequent expression of estrus and fertility at first insemination before day 90 post partum. The data were derived from 1036 postpartum cows reaching 90 days in milk. The following data were recorded for each animal: lactation number, daily milk production at day 50 post partum, calving date, days in milk at estrus and at AI, insemination date, insemination number, inseminating bull, AI technician and body weight at calving, at day 50 post partum and at AI. Of the 1036 cows registered, 817 (78.9%) showed first estrus before day 90 post partum and were inseminated. Using logistic regression procedures and based on the odds ratio a one unit (kg) increase in the daily milk production at day 50 post partum and a one unit (kg) decrease in the BW between calving and day 50 post partum were related to a 1.03-fold increase and a 0.97-fold decrease in the estrus expression rate before day 90 post partum, respectively. Of the 817 cows inseminated before day 90 post partum, 437 became pregnant (53.5%). A one unit increase in the BW at day 50 post partum produced a 1.003-fold increase in the early fertility rate. Pregnancy rate before day 90 was also influenced by the season at calving, bull providing semen and technician. In conclusion, the register of BW during the postpartum period may be a useful tool for evaluating the nutritional status and its relationship with the subsequent reproductive efficiency in dairy cows.

“…Foetal loss was recorded when the days 90-96 diagnosis proved negative. Cows diagnosed as not pregnant and cows with no oestrous signs before days 71-77 in milk were included in a weekly reproductive programme and inseminated either following specific treatment (López-Gatius et al, 2008) or during natural oestrus. Data from cows suffering from any clinical disease before day 120 in milk (open cows) or before day 90 of gestation (pregnant cows) were withdrawn from the study.…”

This study sought to assess the effects of an inactivated phase I vaccine against Coxiella burnetii at the start of the third trimester of gestation on serological profiles, bacterial shedding patterns and subsequent reproductive performance in dairy cows. Cows were randomly assigned to a control (n = 78) or a vaccinated (n = 78) group on days 171-177 of gestation. Samples of placenta and colostrums at parturition, vaginal fluid, faeces, milk (PCR identification) and blood (anti-C. burnetii antibody detection) were obtained on the day of treatment and on days 91-97 post partum, and also on parturition day and weekly on days 1-7, 8-14, 15-21, 22-28 and 29-35 post partum in a subset of 70 animals. By Kaplan-Meier survival analysis, no significant effect of vaccination was detected on any of the reproductive variables studied. According to the odds ratio, C. burnetii shedding on days 171-177 of gestation was highly correlated with seropositivity against C. burnetii (OR = 9.1), while vaccination was not linked to reduced shedding of the bacterium. In shedders compared to others, the likelihood of pregnancy to first AI decreased and increased by factors of 0.26 and 16.1 on days 1-35 and 91-97 post partum, respectively. In conclusion, when administered at the start of the third trimester of pregnancy, the inactivated C. burnetii phase I vaccine failed to reduce bacterial shedding.
