Abstract This study was aimed to assess the effect of adding clinoptilolite in the diet on uterine health and reproductive performance in multiparous lactating dairy cows managed in a tropical pasture-based system above 2500 meters of altitude. Seventy-seven multiparous Holstein crossbred cows were allocated randomly into two groups: clinoptilolite supplemented cows (CLG, n = 42) and non-supplemented cows as control (CG, n = 35). Cows from CLG were supplemented with clinoptilolite from 30 days (50 g/cow/day) before to 60 days after calving (200 g/cow/day). Data were analyzed by general linear model, least squares means and chi-square test of SAS. In CLG cows, percentages of uterine PMN leukocytes (P<0.0001) and proportion of subclinical endometritis (P=0.0187) were lower than in CG. The interval calving to first corpus luteum was shorter (P=0.0759) in CLG than CG, and calving to first service interval was similar between treatments. Cows from CLG became pregnant 35 days earlier than CG cows (P=0.0224). In conclusion, daily addition of clinoptilolite in the diet decreased the proportion of cows with subclinical endometritis and shortened the interval from calving to conception in lactating dairy cows.

<p>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.</p>

Summary Objective: To determine the impact of cytologically determined endometritis (CE) diagnosed according to three different cytological thresholds in the 4th and 6th week postpartum (p. p.) on the subsequent reproductive performance in dairy cows. Material and methods: Dairy cows (n = 222) were clinically examined in the 4th week (Exam I) and in the 6th week (Exam II) p. p. and endometrium samples were collected for cytological examination using the cytobrush method. Three cytological thresholds (percent of polymorphonuclear leucocytes to epithelial cells) were used for categorization of cows: 1) > 18% at Exam I and > 10% at Exam II; 2) > 8% at Exams I and II; 3) > 5% at Exams I and II. The animals were categorized as endometritis positive (CE+) or negative (CE-) according to all cytological thresholds at Exams I and II. For all six experimental groups the following reproductive parameters were calculated: first insemination pregnancy rate, number of services per conception, intercalving period, and total pregnancy rate on day 300 p. p. Results: According to different thresholds prevalence of CE ranged from 48.0% to 65.9% at Exam I and from 26.0% to 34.7% at Exam II. The first insemination pregnancy rate was statistically lower in all CE positive groups at Exam I. Number of inseminations per conception was higher (p < 0.05) in each CE positive cows with exception of group CE+ at Exam II. Intercalving periods were longer in CE cows, and significant (p < 0.05) difference was found for groups ICE+ and ICE- at Exam I. Overall pregnancy rates were similar in cytologically determined endometritis and control cows. Conclusion and clinical relevance: Impaired fertility at herd level may concern only particular reproductive indices. It seems that each herd with subclinical endometritis needs to be evaluated and managed individually, according to the different housing, feeding, and environmental conditions. The first of three thresholds used to cytologically diagnose endometritis seems to be the most reliable when applied in the 4th week p. p.

Abstract The purpose of this study was to evaluate the effect of retained placenta (RP) and clinical mastitis (CM) on the reproductive efficiency of crossbred dairy cows during the postpartum period and to investigate the effect of them in some innate immune system indicators. For this, in the first experiment a total of 232 crossbred dairy cows were evaluated and divided into three groups as: healthy control, RP and CM. The incidence of RP and CM was evaluated after parturition until 30 days postpartum (DPP) and reproductive rates were measured. In experiment 2, 30 crossbred dairy cows were divided into three groups as in Experiment 1. Between 40 and 50 DPP, clinical, gynecological examination and endometrial cytobrush were performed to evaluate subclinical endometritis and gene expression of interleukin- 1β (IL-1β), interleukin-6 (IL-6), chemokine ligand -5 (CCL5), estrogen α (ESR1) and progesterone (PGR) receptors by qRT-PCR analysis. In Experiment 1, the conception rate at 1st AI was lower in RP and CM groups and pregnancy rate at 150 days decreased in cows with CM. Calving-to-1st AI interval and days open were shorter in healthy cows. In Experiment 2 the occurrence of subclinical endometritis was 26.7% and was higher in cows with RP and CM. The expression of IL-1β was increased in RP and CM groups, while IL-6 was less expressed in RP group. The chemokine CCL5, ESR1 and PGR were similar between groups. In conclusion, cows with RP and CM had their reproductive efficiency negatively affected and had they initial pro-inflammatory response improved by the increase of IL-β, while, IL-6 was lower in animals with RP probably because it was evaluated later in the postpartum.

The objectives were to describe the incidence of retained fetal membrane (RFM) and its effect on production and reproduction of dairy cows in tropical environments. Holstein and crossbred Holstein × Gyr cows and heifers calving between May 2012 and May 2013 from 4 dairy farms were enrolled in this study. Retained fetal membranes were defined as the non-expelling of placenta within 12 to 24 h after calving. All cows with RFM were treated with 10 mg kg–1 of oxitetracycline IV and drenching containing 100 g of CaCl2, 100 g of KCl, 200 g of Mg(SO4), and 350 mL of propylene glycol in 25 L of water once per day for 3 days. The incidence of RFM was 14.7% (92/624) in multiparous cows and 11.5% (67/583) in primiparous cows (P = 0.003). The incidence of retained placenta was 14.7% (92/624) during the summer and 14.8% (108/731) during the winter (P = 0.99). Conception rates after first postpartum AI were 32.5% (276/850) and 25.8% (34/132) for healthy cows and cows with RFM, respectively (P = 0.12). More cows that did not have RFM were pregnant at 150 DIM than cows with retained placenta (42.3 v. 29.3%; P = 0.003). Based on predicted 305-day milk yield, cows with retained placenta produced less milk than healthy cows (5924.0 ± 158.0 v. 6315.3 ± 61.0 kg, respectively; P = 0.009). The average peak production was 30.8 ± 0.3 and 29.1 ± 0.7 kg for healthy and RFM cows, respectively (P = 0.02). During the first 60 days in milk, the total milk production for RFM and healthy cows was, respectively, 1305.7 ± 37.3 and 1441.2 ± 15.8 L (P = 0.0008). In conclusion, although season did not influence the incidence of RFM in dairy cows, parity had an effect. Moreover, RFM was associated with a decrease in reproductive efficiency and milk production in dairy cows managed in the tropics. Financial support was received from Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) of Brazil.

Given the influence of retentio secundinarum (RS) on the reproductive performance of cows, the current work aimed to assess the effect of various approaches to the treatment of retained placenta on the main reproductive parameters, primarily on the interval from parturition to the first service, and the insemination index. The trial involved 120 dairy cows in which the placenta was not expelled within 24 h postpartum. The first group (G1, n=60) contained cows in which the retained placenta was not extirpated, but they were administered antibiotics. The second group (G2, n=60) comprised cows in which the placenta was removed manually, and were also administered antibiotics. At the end of the study, 53 cows remained in G1 and 54 cows in G2. According to medicament therapy, both groups were divided into three sub-groups treated with: procaine benzylpenicillin, chlortetracycline hydrochloride or ceftiofur. Comparison of the performance of G1 and G2 cows showed significantly better fertility parameters occurred in the animals from which the retained placenta was extracted manually. The pregnancy rate in the G2 group was remarkably higher than in the G1 group. The average service interval was significantly lower (p<0.05) in the G2 group compared to the G1 group. The best results were obtained with the i.m. administration of ceftiofur after the removal of the placenta.
