“…Han & Kim (2005) reported the intervals from calving to first service and conception were higher in the retained placenta group than in the control group, which is consistent with other reports (Ouweltjes et al, 1996). In some studies, however, the intervals from calving to first service and/or conception were not related to the occurrence of retained placenta (Coleman et al, 1985;Kaneko et al, 1997). RP increases the risk of fatty liver syndrome and ketosis (Han & Kim, 2005); the latter, in turn, delays the postpartum resumption of cyclic ovarian function and prolongs the interval from calving to f irst ovulation (Opsomer et al, 2000).…”

“…In fact, a negative impact of retained placenta on reproductive performance of dairy cows has been widely documented (Fourichon et al, 2000;Gröhn & Rajala-Schultz, 2000). However, others have reported that retained placenta does not significantly alter fertility (Kaneko et al, 1997). Increased occurrence of retained placenta in cows with abnormal partus might be due to lack of tone and slow involution or damage to the uterus by mechanical stress resulting from calving difficulty (Markusfeld, 1984;Markusfeld, 1987).…”

Reproductive efficiency is a critical component of a successful dairy operation and acts as an important component of a profitable dairy farm, whereas reproductive inefficiency is one of the most costly problems facing the dairy industry today. Reproductive problems occur frequently in lactating dairy cows and can dramatically affect reproductive efficiency in a dairy herd. Some of the most common problems include twinning, dystocia, abortion, stillbirth, retained placenta and metritis. These are diverse disorders that are similar in that they all can result in impaired reproductive function. Deciding whether to breed, treat, or cull dairy cows exhibiting one or more of these reproductive problems is a challenge for both veterinarians and dairy producers. In addition, there is considerable controversy among dairy scientists and bovine practitioners regarding the economic impact of these problems in a dairy operation and the most effective management or therapeutic intervention for treating them. Because of this controversy, dairy managers should focus on prevention and control of risk factors associated with each problem rather than on prescriptive therapeutic interventions. Dairy producers should work closely with their herd veterinarian to develop such management strategies and discuss appropriate interventions when necessary (Fricke, 2001).Low fertility reduces the profit by decreasing the average milk production and the number of calves per cow per year. Poor reproductive performance is a major cause of involuntary culling and therefore reduces the AbstractThis review focuses on the potential effects of twinning, dystocia, stillbirth, abortion, retained placenta and metritis on the productive and reproductive performances in dairy cattle. These are diverse disorders that are similar in that they all can result in impaired performance of dairy cows. Reproductive problems occur frequently in lactating dairy cows and can dramatically affect reproductive efficiency in a dairy herd. Poor reproductive performance is a major cause of involuntary culling and therefore reduces the opportunity for voluntary culling and has a negative influence on the subsequent productivity of a dairy herd. Reproductive performance is influenced by the interactive effect of environment, management, health, and genetic factors. In addition, diseases mainly affect dairy cow productivity by decreasing reproductive efficiency, shortening the expected length of productive life and by lowering milk production. Deciding whether to breed, treat, or cull dairy cows showing one or more of these problems is a challenge for both veterinarians and dairy producers. In addition, there is considerable debate among dairy scientists and bovine practitioners regarding the economic impact of these problems in a dairy operation and the most effective management or therapeutic intervention for treating them.

“…Group C (n=19) 89.9 ± 8. was isolated from 56% of cows with retained placenta at 30 days after parturition, but this decreased to 12% at 60 days after parturition in cows that spontaneously expelled their placenta without any treatment [9]. In this study, the rate of T. pyogenes detection in Group NT was 16% which was similar to Kaneko's findings.…”

“…There are many reported treatment methods to prevent endometritis after retained placenta, and the application of PGF2α, GnRH, estradiol (E 2 ), or antibiotics is preferentially used [1,[5][6][7]. Kaneko et al [8,9] reported that the uterus of cows with retained placenta was easily infected with Trueperella pyogenes (T. pyogenes), and that they tended to suffer from endometritis. Furthermore, the percentage of neutrophils in the cells observed in the intrauterine perfusion fluid was high in the uterus after the placenta was retained when compared to a uterus without retained placenta.…”

PGF 2α , GnRH, estradiol (E 2 ), or antibiotics were given to dairy cows with retained placenta after parturition to establish the most suitable treatment to prevent the development of endometritis. One hundred and seventy five parous Holstein cows with retained placenta were allocated to into six treatment groups, and groups were given PGF2α, GnRH, E 2 , or antibiotics at 30 or 45 days after parturition. The intrauterine perfusion fluid was collected at 60 days after parturition, and a bacteriological and cytological examination was conducted. Reproductive performance was also investigated. The detection rate for Trueperella pyogenes in the intrauterine perfusion fluid in each group ranged from 0% to 16%, and T. pyogenes was not isolated in cows that were given PGF2α or E 2 . The percentage of neutrophils observed in the intrauterine perfusion fluid ranged from 37.8 ± 5.3 to 56.3 ± 4.7, and it was lowest in cows given PGF2α and highest in cows given GnRH. The mean number of days from parturition to initial insemination, the mean number of days from parturition to conception and the mean number of artificial inseminations required for conception ranged from 85.9 ± 5.5 to 102.7 ± 8.0, 103.8 ± 9.0 to 162.3 ± 18.6 and 1.5 ± 0.2 to 2.6 ± 0.3, respectively. All three parameters were best in cows that were given a combination of PGF2α and E 2 . The results suggest that administration of PGF2α or E 2 , or ideally both, might be a suitable treatment for cows with retained placenta. However, treatment with GnRH might delay the cleansing of the uterus.

“…This bacterial solution contained 8 to 15 × 10 8 colony forming units/ml of A. pyogenes in physiological saline, and these numbers of A. pyogenes were enough to induce pyometra in the cows [7]. The A. pyogenes used in this study was isolated from a cow with postpartum endometritis using a previously reported method [15]. Four remaining cows were infused with 10 ml of sterile physiological saline as a control.…”

ABSTRACT. To examine the ovarian response to Arcanobacterium pyogenes (A. pyogenes) in uterus, bacterial solution was infused into the uteri of cows, and the follicle and corpus luteum (CL) development were monitored with a real-time ultrasound instrument. In addition, the plasma concentrations of progesterone (P 4 ) and 13, 14-dihydro-15-keto-PGF 2α (PGFM) were determined. A 10 ml bacterial solution that contained A. pyogenes (8 to 15 × 10 8 CFU/ml) was infused into the uterus of eight cows transcervically three days after natural ovulation. As a control, sterile physiological saline was infused into 4 other cows. The dominant follicle developed normally in 8 cows after bacteria inoculation. In 4 of these 8 cows, the developing CL regressed, and the first wave dominant follicles, which normally become atretic, ovulated after the inoculation. In the remaining 4 cows, the CL did not regress. The PGFM concentration increased transiently in all 8 cows after the infusion. The mean PGFM concentration of the cows with a regressed CL was significantly lower (P<0.01) than that of the cows whose CLs did not regress. In the control cows, there was no regression of developing CLs, no ovulation of first wave dominant follicles and no transient increase in PGFM after the infusion of sterile physiological saline. These results show that infusion of A. pyogenes into the uterus did not affect folliculogenesis and might have induced PGF 2α production from the uterus.
