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.

Abstract. The objective of this study was to determine the concentrations of the main indicators of lipomobilization and selected variables of protein profile in dairy cows after calving, including immunoglobulins and acute phase proteins, as well as to evaluate the relationships between the altered lipid metabolism and changes in protein profile. Into the evaluation we included 54 clinically healthy dairy cows of a Slovak spotted breed, low-land black spotted breed and their crossbreeds in the period of 1-2 weeks after parturition. Blood samples were analysed for non-esterified fatty acids (NEFA, mmol/l), β-hydroxybutyrate (BHB, mmol/l), total proteins (TP, g/l), albumin (Alb, g/l), immunoglobulin G (IgG, g/l), haptoglobin (Hp, g/l) and serum amyloid A (SAA, mg/l). In cows with concentrations of NEFA above 0.35 mmol/l (n=20) we found significantly lower mean serum concentrations of total proteins, albumin and IgG than in cows with serum NEFA concentrations below 0.35 mmol/l (n=34) (P<0.001). On the other hand, cows with higher values of NEFA showed significantly higher mean concentrations of BHB, Hp and SAA (P<0.001). The concentrations of NEFA significantly negatively correlated with the values of TP (P<0.001), albumin (P<0.01) and IgG (P<0.001). Significant positive correlations were found between the concentrations of NEFA and BHB, Hp, as well as SAA (P<0.001). Similar correlations were also found between the values of BHB and the variables of protein profile except for albumin. This study indicates strong relationships between NEFA and selected variables of protein profile in cows after parturition.

The objective of this study was to evaluate the dynamics of the body condition score, acute phase proteins (serum amyloid A and haptoglobin) and their relationships in dairy cows of the Slovak Pied Cattle from 3 weeks before parturition to 9 weeks after parturition. Significant differences were found in the means of serum amyloid A (P < 0.01). Haptoglobin concentrations increased from 172.0 ± 0.05 µg/ml to 173.0 ± 0.13 µg/ ml at week 3 and week 1 before the parturition, respectively. The highest value of haptoglobin was recorded in cows 3 week post partum. Cows during the early postparturient period had significantly higher serum amyloid A concentrations compared to cows in the prepartal period (P < 0.01). Significantly higher body condition score values were observed in dry cows (from 4.42 ± 0.20 to 4.25 ± 0.15 points) than in cows after parturition (from 3.90 ± 0.12 to 3.25 ± 0.08 points) (P < 0.001). In the assessment of correlations between the selected acute phase proteins significant positive correlation was found (r = 0.213, P < 0.05). Moreover, negative correlations were found between the body condition score and acute phase proteins. Our results show a strong relationship between the decrease of the body condition score and the increase of acute phase proteins in dairy cows around parturition which indicates the process of a certain form of non-specific inflammation at loss of body fat.

The objective of this study was to evaluate the concentrations of selected acute phase proteins – haptoglobin (Hp) and serum amyloid A (SAA), and selected variables of energy metabolism in blood serum of dairy cows during different stages of the pre- and postpartal period. The analyses were performed in dairy cows of the Slovak spotted breed and its crossbreeds (n = 57). The cows were divided into 9 groups according to the evaluated part of reproduction cycle – from 4 weeks before parturition to 10 weeks after parturition. Significant differences were found in mean Hp and SAA concentrations during the monitored period (P < 0.05 and P < 0.001, respectively). Cows during the early postparturient period had significantly higher Hp and SAA concentrations compared to cows in later postparturient period (P < 0.05). Significant differences throughout the period under study was found also in means of total cholesterol (P < 0.01), triglycerides (P < 0.001), and non-esterified fatty acids (P < 0.001). Concentrations of Hp during this period were positively correlated with SAA (R = 0.919; P < 0.001). Moreover, significant correlations were found between Hp and non-esterified fatty acids, Hp and β-hydroxybutyrate, as well as between SAA and non-esterified fatty acids. Our results indicate that the acute phase response occurs in cows around parturition, and suggest that there are relationships between mediators of immune response and several indices of energy metabolism. Our results also suggest that in cows with higher concentrations of non-esterified fatty acids, indicating a certain degree of lipid mobilisation, higher values of acute phase proteins may be found.

The purpose of this study was to evaluate the effects of ketoprofen (KTP), flunixin meglumine (FLM), and meloxicam (MLX) administration on acute-phase proteins after dehorning in Holstein heifers. A total of 21 Holstein heifers were enrolled into three groups of equal size (n=7) and administered ketoprofen, flunixin meglumine, or meloxicam, at doses of 2.2 mg/kg, 1.1 mg/kg, and 1 mg/kg body weight, respectively. Serum amyloid A, haptoglobin, and ceruloplasmin levels were determined before the administration of the three drugs (0 hrs) and at 6, 12, 24, 48, and 96 hours post-administration. The mean values (±SD) obtained revealed no significant alteration in APP levels at 0 hrs in any of the three groups. Time-dependent alterations, however, were significant in all groups. Group-time interactions were significant (P < 0.001) for ceruloplasmin concentrations, whereas results for serum amyloid A and haptoglobin levels were deemed non-significant. Inter-group interaction revealed no significant findings regarding serum amyloid A and ceruloplasmin levels, but haptoglobin levels showed a significant difference between the KTP and FLM groups at 48 hrs. It may therefore be reasonably suggested that KTP, FLM, and MLX could all be administered to effect slight changes in acute phase proteins.

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.

The aim of the present study was to compare the concentrations of two acute phase proteins, haptoglobin (Hp) and serum amyloid A (SAA), in serum and milk of Holstein-Friesian dairy cows grouped according to somatic cell count thresholds (< 100,000 < 400,000 < 400,000 cells/ml) in composite milk samples. The SCC was assessed quantitatively by FOSSOMATIC 90 analyser; serum and milk Hp and SAA concentrations were determined using commercial ELISA kits (Tridelta Development, Ltd., Wicklow, Ireland). We have found a significantly higher Hp and SAA concentrations in the group with SCC > 400,000 cells/ml compared to groups with lower SCC thresholds in composite milk samples. In contrast, significant differences were not demonstrated between the groups in Hp and SAA concentrations determined in serum. The concentrations of Hp in serum and milk were found to be correlated (r = 0.69, P = 0.0003), whereas there was a lower correlation trend in the case of serum versus milk concentrations of SAA (r = 0.43, P = 0.0478). High significant correlations were observed either between milk haptoglobin values and SCC or milk serum amyloid A concentrations and SCC (r = 0.83, r = 0.81, P < 0.0001; respectively). An increase in SCC in cows suffering from mastitis has been accompanied by strong elevation of the milk Hp and SAA, significantly correlated with serum Hp (r = 0.64, P = 0.0014) and poorly correlated with SAA values determined in serum (r = 0.43, P = 0.0478). According to the results obtained in this study we can conclude that measurements of the acute phase proteins, haptoglobin and serum amyloid A predominantly in milk, may be a useful tool in diagnosing mastitis and may be a useful marker of milk quality.

The acute phase response—trauma, tissue necrosis, infection, inflammation, and malignant neoplasia induce a complex series of nonspecific systemic, physiological, and metabolic responses including fever, leucocytosis, catabolism of muscle proteins, greatly increased de novo synthesis and secretion of a number of ‘acute phase’ plasma proteins, and decreased synthesis of albumin, transthyretin, and high- and low-density lipoproteins. The altered plasma protein concentration profile is called the acute phase response. Acute phase proteins—these are mostly synthesized by hepatocytes, in which transcription is controlled by cytokines including interleukin 1, interleukin 6, and tumour necrosis factor. The circulating concentrations of complement proteins and clotting factors increase by up to 50 to 100%; some of the proteinase inhibitors and α‎1-acid glycoprotein can increase three- to fivefold; but C-reactive protein (CRP) and serum amyloid A protein (an apolipoprotein of high-density lipoprotein particles) are unique in that their concentrations can change by more than 1000-fold. C-reactive protein—this consists of five identical, nonglycosylated, noncovalently associated polypeptide subunits. It binds to autologous and extrinsic materials which contain phosphocholine, including bacteria and their products. Ligand-bound CRP activates the classical complement pathway and triggers the inflammatory and opsonizing activities of the complement system, thereby contributing to innate host resistance to pneumococci and probably to recognition and safe ‘scavenging’ of cellular debris. Clinical features—(1) determination of CRP in serum or plasma is the most useful marker of the acute phase response in most inflammatory and tissue damaging conditions. (2) Acute phase proteins may be harmful in some circumstances. Sustained increased production of serum amyloid A protein can lead to the deposition of AA-type, reactive systemic amyloid.

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.
