Abstract This research communication describes (1) the comparison of acute-phase protein (APP) concentrations in transition dairy cows on different farms using both pooled and individual blood samples, and (2) the association among different APP and clinical health parameters. The first hypothesis was that early postpartum dairy cows from different farms differ in the level of inflammation, which might be determined using APP assays in both pooled and individual blood samples. The second hypothesis was that the APP haptoglobin (Hp) might be the most sensitive parameter to detect cows at risk of excessive postpartum inflammation concomitant with systemic disease. Serum concentrations of Hp, serum amyloid-A (SAA), total protein (TP), albumin (Alb), coeruloplasmin (Cp) and C-reactive protein (CRP) in 100 fresh lactating cows (within 0–8 d postpartum) from 10 farms were compared and associated to clinical health parameters (rectal body temperature, vaginal discharge (Metricheck™ score), rumen fill, vulvovaginal laceration) using both pooled and individual blood samples. Mean serum concentrations of Hp, SAA and TP revealed significant differences among farms. Pooled serum samples of farms showed high correlations with the mean of individual samples. Only Hp was significantly positively correlated to both body temperature and Metricheck™ score. In conclusion, Hp differentiates dairy farms regarding the inflammatory state of transition cows using individual and pooled serum samples within the first week postpartum. It also mirrors the individual degree of inflammation, thus proving to be a diagnostic parameter of high interest during the periparturient period.

Abstract The aim of this study was to evaluate the acute phase response of dairy cows to repeated liver biopsy in order to estimate the safety of this procedure during the transition period. Liver biopsies (up to 1000 mg of liver tissue) were conducted twice a day, 7 days before expected parturition and 3 days after calving. The number of needle insertions for each biopsy was recorded and was dependent on the amount of obtained tissue. Blood samples were taken on day 7 before expected parturition, then on days 3, 4, 7 and 14 after calving. Body temperature was measured daily in all 30 cows from day 3 until day 14 after calving. The concentrations of haptoglobin, serum amyloid A, fibrinogen and interleukin-6 were determined in serum and plasma. In 16.7% of cows, the rectal body temperature rose by ≥ 0.5°C on the day after liver biopsy. Although the concentrations of haptoglobin, serum amyloid A and fibrinogen increased significantly after calving (p<0.01), there was no influence of the number of biopsies on the acute phase reaction and repeated biopsy during the transition period had no effect on body temperature. Therefore, the procedure may be regarded as safe for cows during the transition period.

The purpose of this study was to assess the diagnostic value of fibrinogen, haptoglobin, and serum amyloid A determination in the monitoring of the treatment of limb diseases in dairy cows. Fourteen lame cows were examined, while 10 clinically healthy cows constituted the control group. Blood samples from the ill animals were collected on three occasions: (1) upon arrival at the clinic, (2) between the third and sixth day after arriving, and (3) upon return to the owner. Blood samples from the control cows were collected once. Plasma levels of fibrinogen, haptoglobin, serum amyloid A, and total serum protein and its fractions (albumin, &alpha;-, &beta;-, &gamma;-globulins) were measured. Significantly higher fibrinogen, haptoglobin, and serum amyloid A levels were observed in the affected cows upon arrival at the clinic than in the control cows. Based on the changes in fibrinogen, haptoglobin, and serum amyloid A concentrations, the cows were divided into those with a systematic decrease in acute-phase protein levels during treatment (Group I, <I>n</I> = 6) and those which showed an increase in one or more acute-phase proteins despite treatment (Group II, <I>n</I> = 8). A stepwise decrease in the examined acute-phase proteins was observed in the first group and indicated an uncomplicated course of treatment; however, treatment of the second group did not appear to be wholly successful. A majority of the cows under treatment (<I>n</I> = 13) exhibited abnormal levels of the examined acute-phase proteins upon return to the owner. This indicates that these patients did not recover completely. The monitoring of plasma acute-phase protein concentrations can be a valuable complement to the clinical assessment of the treatment course and in the early detection of disease complications.

Hindlimb unloading (HU) is known to induce physiological alterations in various organ systems that mimic some responses observed after exposure to microgravity. In the present study, the effects of up to 4 wk of HU on the liver were assessed in male Wistar rats and two mouse strains: endotoxin-sensitive C57BL/6 mice and endotoxin-resistant C3H/HEJ mice. Plasma levels of endotoxin, a known stimulator of hepatic injury, were measured in portal and systemic blood samples. Endotoxin was elevated by ∼50% in portal blood samples of mice and rats but was not detectable in systemic blood. This low-grade portal endotoxemia was associated with hepatic injury in rats and C57BL/6 mice as indicated by inflammation and elevated serum transaminase activities. Blood levels of the cytokine TNF-α were increased by ∼50% in C57BL/6 mice; no significant elevation of this cytokine was detected in rats. Messenger RNA levels of the acute-phase proteins serum amyloid A, haptoglobin, and lipopolysaccharide binding protein were significantly enhanced after 3 wk of HU in endotoxin-sensitive rodents. In contrast, no histological changes or significant increases in serum enzyme activity were detected after HU in C3H/HEJ mice despite portal endotoxin levels of 222 ± 83.4 pg/ml. At the 3-wk time point, expression of acute-phase proteins was not elevated in C3H/HEJ mice; however, expression after 4 wk of HU was similar to endotoxin-sensitive rodents. In conclusion, these findings indicate that HU induced mild portal endotoxemia, which contributed to the observed hepatic injury in endotoxin-sensitive rodents.

Abomasal Displacement

Abomasal displacement (AD) to the left is a common disease in high-yielding dairy cows after parturition. In view of the previously reported changes in tissue neuropeptide concentrations in cows with AD, the primary aim of this study was to evaluate the effect of AD and breed on serum neuropeptide concentrations. For this purpose, blood samples of 33 German Holstein (GH) cows with AD, 36 healthy controls (GH), and 32 healthy German Fleckvieh (GF) cows were collected, and concentrations of substance P (SP), vasoactive intestinal polypeptide (VIP), and interleukin1β (IL-1β) were measured via commercially available ELISA kits. To examine the effect of AD, we compared GH cows with and without AD and observed no significant effects of AD on SP, VIP, or Il-1 β concentrations. To evaluate the effect of breed, we compared healthy GH with healthy GF cows and detected markedly higher VIP serum levels in the healthy GF cows (p < 0.01). No significant differences in SP or IL-1β were detected. According to our results, there seems to be no effect of AD on the serum concentrations of SP, VIP, or IL-1 β. In contrast, there seems to be a breed difference concerning serum VIP concentrations.

In this study, the concentrations of two acute-phase proteins (APPs), haptoglobin (Hp) and serum amyloid A (SAA), were quantitatively assessed in serum samples from cattle naturally infected with paratuberculosis (PTB). APP profiles were compared across 190 animals classified according to the different pathological forms associated with infection: uninfected (n = 59), with focal lesions (n = 73), multifocal lesions (n = 19), and diffuse paucibacillary (n = 11) and diffuse multibacillary lesions (n = 28). Our results showed a significant increase in both APPs in infected animals compared to the control group, with differences depending on the type of lesion. Hp and SAA levels were increased significantly in all infected animals, except in cows with diffuse multibacillary lesions that showed similar values to non-infected animals. The expression pattern of both APPs was similar and negatively correlated with the antibody levels against PTB. These results indicate that the release of Hp and SAA is related to the presence of PTB lesions associated with a high cell-mediated immune response and a lower bacterial load, suggesting that the pro-inflammatory cytokines that are associated with these forms are the main stimulus for their synthesis. These molecules could show some potential to be used as putative biomarkers of PTB infection, particularly for the identification of subclinical animals showing pathological forms related to latency or resistance to the development of advanced lesions.

The objective of the present study was to compare the concentrations of acute phase proteins and selected variables of protein metabolism in dairy cows of the Slovak Spotted breed from 4 weeks before parturition to 10 weeks after parturition. Acute phase proteins - haptoglobin (Hp) and serum amyloid A (SAA) - and variables of protein metabolism - total proteins, albumin, urea, creatinine, total immunoglobulins - were evaluated in blood serum. Significant differences were found in average values of the Hp and SAA concentrations in several groups during the monitored period (P < 0.05 and P < 0.001, respectively). The Hp and SAA concentrations in cows during the early postparturient period were significantly higher compared with the later postparturient period. Throughout the monitored time we found differences in mean values of total proteins (P < 0.001), urea (P < 0.001), and total immunoglobulins (P < 0.05). The concentrations of albumin decreased progressively in the postparturient period until 4 weeks after parturition. In the assessment of correlations between the monitored variables in the mentioned period we found significant correlations between Hp and SAA (r = 0.916; P < 0.001), total proteins and urea (r = 0.668; P < 0.05), total proteins and total immunoglobulins (r = 0.827; P < 0.01), and between total immunoglobulins and urea (r = 0.899; P < 0.001). The above mentioned results indicate that in the time around parturition there are significant changes in concentrations of acute phase proteins, as well as in the whole protein metabolism of dairy cows. These facts suggest that the postparturient period is a critical biological phase, throughout which there is the highest incidence of metabolic disorders.

Strong Relationships

The objective of this study was to investigate the relationship between activation of acute phase response and fatty liver in transition dairy cows. Fatty liver was induced in dairy cows by feeding 8 kg of cracked corn 1 mo before the expected day of parturition. Liver and blood samples were obtained at days -4, 3, 8, 12, 14, 22, 27, and 36 postpartum. Cows that developed fatty liver (n = 4) reached peak total lipids in the liver at day 12 postpartum with 11.4% (wet wt.) compared with 6.6% in control cows (n = 4). Cows with fatty liver had greater plasma tumor necrosis factor-alpha (TNF-α), nonesterified fatty acids (NEFA), and lower lactate concentrations than did control cows at day -4. During highest concentrations of total lipids in the liver, for at least one time-point, fatty-liver cows had greater concentrations of plasma serum amyloid A (SAA), haptoglobin, and NEFA and lower concentrations of calcitonin gene-related peptide (CGRP), prostaglandin E2 (PGE2), cortisol, and TNF-α than did control cows. Concentrations of total lipids in the liver at 12 d postpartum were correlated (a) positively with plasma TNF-α, SAA, and NEFA and negatively with plasma CGRP before calving, (b) positively with plasma SAA, haptoglobin, and NEFA and negatively with plasma PGE2, CGRP, total cholesterol, and glucose at days 3, 8, and 12 postpartum, and (c) negatively with concentrations of plasma glucose, lactate, and total bilirubin after day 12 postpartum. In conclusion, this study indicates that the acute phase response occurs in cows with fatty liver as well as strong relationships between mediators of immune response and fatty liver.

We evaluated the effect of different storage conditions on the concentration of serum total proteins and their electrophoretic fractions in sheep. Blood samples were collected from 12 female Comisana sheep, and each serum obtained was divided into 4 aliquots. The first aliquot was analyzed immediately after separation (T0); the second was refrigerated at 4°C and analyzed after 24 h (T1), 48 h (T2), and 72 h (T3); the third was stored at −20°C immediately after centrifugation and analyzed after 2 days (T4); and the last aliquot was stored at −20°C after 24-h refrigeration and analyzed after 1 wk (T5). The concentrations of serum total proteins and their electrophoretic fractions (albumin, α-, β1-, β2-, and γ-globulins) was determined. A statistically significant ( p < 0.05) effect of storage conditions on all serum electrophoretic protein fractions and on the albumin-to-globulin (A/G) ratio was found. The values of albumin, α-globulins, and A/G ratio increased at T4 with respect to T0. The levels of α-globulins were higher at T1 than T0; the β1-globulins levels changed at T3, whereas the β2- and γ-globulins values as well as the A/G ratio changed at T2 and T3. At T4, we found an increase in the serum concentrations of albumin, α1-globulins, and on the A/G ratio, and a decrease of γ fraction. At T5, the concentration of α-globulins was higher than at T0. Hence, we recommend electrophoretic analysis of fresh ovine serum samples or of samples refrigerated for no more than 24 h to obtain accurate data.

Twenty-five lactating dairy cows were treated with either saline (control), 500 μg gonadotropin-releasing hormone (GnRH), GnRH + 10 mg estradiol 17β (E2), E2, or GnRH + E2 + 25 mg prostaglandin F2α (PGF2α) at approximately 11 days postpartum. Blood samples were taken at the time of injection and then twice each week for about 30 days. Treatment with GnRH alone gave the largest LH peak; LH production appeared to be inhibited when E2 was given with GnRH. Plasma estrogen concentrations were above 1 ng/ml for 12 h in all animals receiving estrogen alone or in combination. None of the treatments hastened initiation of cyclic activity which began at an average of 19 days postpartum. It seems unlikely that postpartum anestrus is an important constraint to early rebreeding in dairy cows.
