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.

Postpartum uterine infections affect ovarian function and delay ovulation in cattle. As dietary fats can affect immune cell function, we investigated the influence of prepartum diets on postpartum uterine inflammatory status (UIS) as assessed 25 ± 1 days postpartum by endometrial cytology (normal: ≤8% polymorphonuclear cells (PMN) vs subclinical endometritis (SCE): >8% PMN) and associations between SCE, pro- and anti-inflammatory cytokine gene expression and ovarian function. During the last 5 weeks of gestation, dairy cows received a diet supplemented with 8% rolled sunflower (n = 10) or canola seed (n = 9) or no oilseed (n = 9). Ovaries were scanned until 35 days postpartum. Prepartum diets did not influence SCE, but a preovulatory-size follicle developed sooner (P ≤ 0.05), the interval to first ovulation was shorter and the proportion of cows ovulating within 35 days postpartum was greater in the sunflower seed group. Although mRNA expression of cytokines was not affected by diet, cows with SCE had higher (P ≤ 0.05) expression of interleukin-1β (IL1B), interleukin-8 (CXCL8), IL10 and tumour necrosis factor-α (TNF) than normal cows. The interval (mean ± s.e.m.) from calving to preovulatory-size follicle was shorter (P ≤ 0.05) in normal (13.2 ± 0.9 days) than SCE cows (18.7 ± 1.4 days). In summary, a prepartum diet supplemented with sunflower seed positively influenced postpartum ovarian function without affecting UIS or pro- and anti-inflammatory cytokine gene expression in endometrial cells.

The objective of this study was to determine thiol/disulphide homeostasis (TDH) in infertile cows with subclinical endometritis (SCE). Endometrial cytological samples were collected using a cytobrush to diagnose SCE in 36 infertile cows. According to the results of the cytology examination, those with acute endometritis were classified as Group I (n = 20) and those with chronic endometritis were classified as Group II (n = 16). A control group was formed of heifers as Group III (n = 20). Blood samples were taken from each group on the day of diagnosis (day 0) to analyse TDH. In the cytology examination, both the Giemsa method and immunocytochemical staining were applied to determine chronic inflammation and activity status. In 55.55% (20/36) of the infertile cows with cytological endometritis, the inflammation was determined to be active, and in 44.44% (16/36) it had become chronic. The native thiol and total thiol levels were found to be statistically significantly lower in the acute (206.54 ± 8.30 μmol/L; 227.11 ± 9.30 μmol/L) and chronic SCE cases (225.15 ± 11.89 μmol/L; 247.96 ± 10.80 μmol/L) compared to the heathy control group (308.47 ± 13.59 μmol/L; 336.83 ± 15.5 μmol/L respectively) (P<0.001). Disulphide levels, disulphide/total thiol, native thiol/total thiol and disulphide/native thiol ratios were similar in all the groups (P>0.05). The diagnostic accuracy of native thiol, which can be used in the diagnosis of SCE, was 92.8%, that of total thiol was 89.3% and that of disulphide was 64.3% according to the ROC curve analysis. These results demonstrate that TDH is a reliable and sensitive indicator of oxidative stress in cow SCE, and that abnormal TDH might play a role in SCE pathogenic mechanisms. This is the first study to evaluate thiol/disulphide homeostasis in dairy cows with SCE as a new indicator of oxidative stress.
