“…Plasma AST activity returned to normal reference values within 100 hours after doxycycline‐induced muscle trauma in pigeons. AST activity currently is considered to be a very sensitive but nonspecific indicator of hepatocellular disease in other avian species as well, and is frequently used with the muscle‐specific enzyme, creatine kinase (CK) to differentiate between liver and muscle damage 37,38 …”

“…Galactose clearance and galactose single‐point concentrations (GEC‐SA) were evaluated during a prospective study on the effects of partial hepatectomy in cockatoos 37 . In the study, both galactose clearance and GEC‐SA appeared to be more sensitive indicators of hepatic insufficiency than plasma enzyme activities or BA levels, and were able to detect an 18% loss of hepatic mass.…”

Birds have evolved alternate physiologic strategies to contend with dehydration, starvation, malnutrition, and reproduction. Basic anatomic and functional differences between birds and mammals impact clinical chemistry values and their evaluation. Interpretation of the results of standard biochemical analyses, including BUN, alanine aminotransferase, aspartate aminotransferase, creatine kinase, gamma glutamyltransferase, bilirubin, ammonia, alkaline phosphatase, cholesterol, bile acids, glucose, albumin, globulins, calcium, phosphorus, prealbumin (transthyretin), fibrinogen, iron, and ferritin, is reviewed and discussed in relation to these physiological differences. The use and interpretation of alternative analytes appropriate for avian species, such as uric acid, biliverdin, glutamate dehydrogenase, and galactose clearance, also are reviewed. Normal avian urine and appropriate use of urinalysis, an integral part of laboratory diagnosis in mammalian species that frequently is omitted from avian diagnostic protocols, is discussed.

“…The liver samples we took were very small (maximum 181 mg) compared to the size of the lightest duck (372 g) we sampled. Even sizable (6% of liver mass) hepatectomies did not alter serum chemistries or liver function tests in Galahs (Eolophus roseicapillus), and liver mass as a percentage of body weight was restored within 7 days of surgery (Jaensch et al, 2000). Although not measured, liver function of the Harlequin Ducks was not likely affected by the liver biopsies we performed.…”

“…The blood enzyme activity appears to be a suitable diagnostic method to evaluate the hepatic function and reflect the degree of hepatocellular damage and leakage, tissue damage or organ dysfunction in birds [33]. As such, liver damage can be indicated by analyzing the plasma levels of ALT, AST, ALP, GGT and GLDH as the most frequently used biomarkers in clinical practice [33,34]. The plasma levels of ALT and AST reflect the integrity of hepatocytes, while ALP and GGT have limited roles in the diagnosis of hepatic diseases in birds [33,35].…”

The plasma levels of ALT and AST reflect the integrity of hepatocytes, while ALP and GGT have limited roles in the diagnosis of hepatic diseases in birds [33,35]. Among all the blood parameters, the AST level is considered as the most specific and sensitive enzyme for detecting avian liver and muscle damage [33], and its level was not modified in response to the supplementation with seaweed, heat stress or among strains.…”

This study was planned to investigate the effects of seaweed supplementation, genetic strain, heat stress and their interactions on laying hen performances, blood chemistry and hematology. In a short-term trial, laying hens of the two genetic lines Lohman LSL-Lite (White) and Lohman Brown-Lite (Brown) were supplemented with Chondrus crispus (CC) at 3% for 21 days, while a control group was not. In a long-term trial, the same two strains were assigned to control (0%), 3% red seaweed Chondrus crispus (CC) or 0.5% brown seaweed Ascophyllum nodosum (AN)-supplemented diets for 41 weeks, concluding with a four-week control or heat-stress period. The White hens displayed higher egg production and a lower feed/egg ratio. The short-term inclusion of CC significantly reduced the feed intake, weight gain and feed/egg ratio. The long-term seaweed intake affected the plasma albumin and gamma-glutamyl transferase (GGT) (p < 0.05), and there were significant strain-heat stress interactions; heat stress in the Brown birds was associated with reduced protein, globulin and glucose and increased cholesterol and GGT levels and higher heterophil-to-lymphocyte (H/L) ratios (p < 0.05) in response to heat stress (p < 0.05). In conclusion, a long-term seaweed supplementation affected the plasma protein and enzyme profiles, yet had little effect on hen leukocyte counts and the overall performance.
