“…ALT, AST and GGT are liver associated enzymes that may leak into the bloodstream as a consequence of liver damage, and serum ALT activity is considered to be a nonspecific marker for bovine liver damage (Rafia et al, 2012). In agreement with Fiore et al (2016), the ALT activity increased from 25 ± 2 d post-partum until the end of the experimental period, showing a long term protective response in SUPP and MON meaning lower values in respect to CTRL.…”

The objective of this study was to compare the effect of two different preventive protocols, on serum β-hydroxybutyrate (BHB) concentration and liver health indices pre-partum and during early-lactation in high-yielding Holstein dairy cows. One hundred cows were randomly divided into three groups: control group (CTRL, n = 20, without preventive treatment), second group (SUPP, n = 40 animals treated with a compound based on acetyl-methionine, inositol, cyanocobalamin, l-alanine, l-arginine, l-threonine, l-glutamic acid supplementation and α-lipoic acid) and third group (MON, n = 40 animals treated with monensin). Blood samples were collected from all cows at on 3 occasions pre-partum and 3 occasions post-partum. Body condition (BCS) score was evaluated and glucose, non-esterified fatty acids (NEFA), BHB, triglycerides, total cholesterol, alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyltransferase (GGT), total bilirubin, total proteins, globulins, albumin and urea concentrations were assessed. Two-way repeated measures analysis of variance was applied. Statistically significant differences among the three experimental groups were found in the values of all studied parameters (P < 0.05). Our results confirm the established beneficial effect of MON treatment in decreasing BHB levels and increasing glucose availability after calving. Serum biochemical analysis revealed the expected post-partum alterations attributable to adaptations that influenced the metabolism and liver function in CTRL, whereas these alterations were reduced or absent in SUPP and MON. Results from the present study suggest that both preventive protocols, but in particular SUPP, could positively affect selected indicators of energy metabolism reducing the risk of hyperketonaemia and increase of liver function in Holstein dairy cows, both pre- and post-partum.

“…An animal’s health can be defined as the absence of diseases determined by clinical examinations combined with various diagnostic tests. Serum biochemical reference values are used to establish normality and to diagnose diseases and physiological alterations [ 3 , 4 , 7 , 9 , 16 , 17 ]. Although many reference values have been established for dairy cows [ 3 , 4 , 17 ], there have been few published references for beef cows [ 9 , 16 ].…”

“…In particular, the reports for Japanese Black cows have been very scarce [ 20 ]. It is well known that variables, such as reproductive, as well as lactation status have an influence on many blood parameters [ 3 , 4 , 9 , 16 , 17 ]. To the best of the authors’ knowledge, reference values have not been established for particular stages of Japanese Black breeding cows.…”

To obtain blood biochemical basic data of Japanese Black breeding cows in Kagoshima Prefecture, Japan, blood samples were obtained from 857 clinically healthy multiparous cows on 71 farms. Cows were divided into three stages: the prepartum stage (between 20 and 80 days before parturition, n=290), lactation stage (between 20 and 80 days after parturition, n=283) and maintenance stage (between 120 and 200 days after parturition, n=284). The mean concentration of total protein and total cholesterol, and the mean activities of aspartate aminotransferase in the lactation stage tended to be higher than those in the prepartum and maintenance stages. The mean concentration of glucose in the prepartum stage tended to be lower than that in the lactation and the maintenance stages. The mean concentration of nonesterified fatty acids and beta-hydroxybutyrate in the prepartum stage tended to be higher than those in the lactation and maintenance stages. The mean concentration of serum retinol was approximately 30 µg/dl in all stages. These results suggest that the blood biochemical values of multiparous Japanese Black cows vary with breeding stages, and it is considered that the blood parameters obtained in this study are useful as indices for health management of Japanese Black breeding cows.

Evaluation of the correlation between serum biochemical values and liver ultrasonographic indices in periparturient cows with different body condition scores

Abstract: Liver ultrasonographic features were poorly correlated with changes of serum biochemical variables. This suggests that liver ultrasonography is not a good technique for estimating functional liver abnormalities in periparturient cows.
