239 HORMONE PROFILE AND OVARIAN FOLLICLE DIAMETER IN EARLY POSTPARTUM LACTATING COWS

The purpose of this study was to assess the ovarian follicle diameter and hormone status during early postpartum in cows. Eighteen Holstein cows, aged 3.5–5.5 years and of 400–600 kg BW with normal calving, were examined every 3rd day starting from Day 15 until Day 33 postpartum. Blood samples for hormonal (progesterone (P4) and estradiol-17β (E2)) analyses were withdrawn from the coccygeal vein every 3rd day until the end of the experiment. The ovarian follicular number and size were verified and measured using a sector vaginal transducer ultrasound scanner (6.5 MHz probe, SA 600; Medison Co., Seoul, Korea). The least squares means (±SEM) are presented for each day (GLM of SAS). In postpartum cows, E2 levels were 27.09 ± 5.22 pg, 24.50 ± 5.76 pg, 26.92 ± 4.62 pg, 25.53 ± 3.74 pg, 27.47 ± 5.72 pg, 26.48 ± 8.06 pg for Days 15, 18, 21, 24, 27, 30, and 33, respectively, 28.01 ± 7.52 pg; P4 levels were 1.35 ± 1.14 ng, 2.41 ± 1.70 ng, 2.85 ± 2.26 ng, 2.88 ± 1.90 ng, 2.91 ± 1.91 ng, 3.04 ± 2.31 ng, and 4.04 ± 3.70 ng for Days 15, 18, 21, 24, 27, 30, and 33, respectively. The ovarian follicle diameter was 12.36 ± 3.31 mm, 11.91 ± 2.99 mm, 13.09 ± 3.37 mm, 13.55 ± 2.76 mm, 14.55 ± 3.68 mm, 15.64 ± 5.53 mm, 17.45 ± 3.22 mm for Days 15, 18, 21, 24, 30, and 33, respectively. The present results show that mean plasma concentration of P4 and mean follicle diameter gradually increased from Day 15 to Day 33 postpartum. It is concluded that monitoring of P4 and E2 during early postpartum period would be useful to predict the ovarian starts for early rebreeding in dairy cows.

Early Postpartum

It is important to clarify how the breastfeeding method affects women’s mental health, and how women’s mental health affects the breastfeeding method in the early postpartum period when major depression and other psychiatric problems are most likely to occur. This study aimed to examine this bidirectional relationship in the early postpartum period. Participants were 2020 postpartum women who completed the Hospital Anxiety and Depression Scale (HADS) and Mother-to-Infant Bonding Scale (MIBS). We obtained data for participants’ breastfeeding method for four weeks after childbirth. We performed a path analysis with factors including breastfeeding method (exclusive breastfeeding or non-exclusive breastfeeding), parity (primipara or multipara), the two HADS subscales (anxiety and depression), and the two MIBS subscales (lack of affection and anger and rejection). The path analysis showed that breastfeeding method did not significantly affect depression, anxiety, and maternal–infant bonding in the early postpartum period. Women with higher anxiety tended to use both formula-feeding and breastfeeding. Our study suggests that exclusive breastfeeding is not associated with maternal-fetal bonding in early postpartum, considering depression, anxiety, and parity.

This study investigated the efficacy of intrauterine infusion of a chitosan solution (CHT) on uterine recovery in early postpartum dairy cows with or without endometritis, and their subsequent reproductive performance. In Experiment 1, cows with endometritis at 3 weeks postpartum were administered CHT (n = 5) and prostaglandin F2α (PGF2α) (n = 4). Untreated cows (n = 7) served as the control group. In Experiment 2, 18 cows with a normally recovered uterus at the fresh cow check (mean, 35 days postpartum) were assigned to the CHT (n = 10) and control (n = 8) groups, and intrauterine infusion was conducted in the CHT group. Overall, in Experiment 1, the percentage of polymorphonuclear leukocytes significantly declined in the CHT group (32.3 ± 10.2 to 5.5 ± 2.4, p < 0.05) from week 3 to week 5, but no decline occurred in the PGF2α and control groups. In Experiment 2, the CHT and control groups showed no significant differences in reproductive parameters, suggesting the absence of adverse effects of CHT on fertility. These results suggest that intrauterine infusion of CHT in the early postpartum period effectively accelerates uterine recovery from endometritis and might be a suitable replacement for PGF2α administration.
