“…In the present study, AST enzyme activities were significantly lower during late gestation than in early or mid-gestation (Table 2), but were higher than the values reported for adult horses (Kaneko et al, 1997). This is concordant with the findings of earlier studies (Flisińska-Bojanowska et al, 1991;Mariella et al, 2014), in which AST values were lower near term than in non-pregnant mares. The reason remains unclear, but a possible explanation is the strengthening of anabolic processes during this period.…”

The aims of this study were to detect physiological changes in blood biochemical parameters throughout gestation, to compare the findings in nonpregnant and pregnant Lipizzaner mares in early-mid and late pregnancy, and to provide reference values for clinical chemistry parameters in this horse breed. A total of 136 venous blood samples were collected from 20 pregnant and 10 nonpregnant (control) asymptomatic Lipizzaner broodmares for biochemical analyses. Twelve parameters (albumin, total protein, urea, triglycerides, glucose, creatinine, alkaline phosphatase, aspartate transaminase, glutamate dehydrogenase, gammaglutamyltransferase, creatine kinase and lactate dehydrogenase) were measured. For the statistical analyses, correlation, analysis of variance and Kruskal-Wallis H-test were used to evaluate the possible associations between parameters. Serum triglyceride levels proved to be significantly different in pregnant mares compared to the control group. Total protein and urea levels significantly decreased, while glucose, triglyceride and glutamate dehydrogenase values increased from approx. the fifth month of gestation until parturition. Four biochemical parameters (albumin, aspartate transaminase, total protein and urea) were lower and three other variables (glucose, alkaline phosphatase and creatinine) were significantly higher in late-term pregnant mares than in mares in early or mid-gestation. It is concluded that reference values not only reflect the species, breed and sex but also the reproductive status of animals. Key words:Reference values, Lipizzaner pregnant mare, gestation, biochemical parameters, late pregnancyThe values of haematological and biochemical parameters in the peripheral blood change dynamically in physiological and pathological conditions. To provide the highest standard of care, veterinarians require appropriate reference values corresponding to the species, breed, sex and reproductive status of the patient. Recent studies have evaluated haemostatic and haematological changes oc-*

“…Our findings are consistent with earlier studies conducted by FlisiŃska-Bojanowska et al (1991) and Mariella et al (2014), which reported lower AST values in nearterm pregnant mares than non-pregnant mares. Similar results were also observed in Spanish pure-bred broodmares by Naseema et al (2017) and Satué and Montesinos, (2013).…”

Background: The pure-bred Barb horse is a beloved breed from the Great Maghreb. Despite the breed’s prominence in Algeria, no gestational hematological or biochemical research has been done on this breed. Objectives: This study aimed to compare the hematological and biochemical parameters of pregnant and non-pregnant Barb mares in the first, second, and third trimesters of pregnancy. Methods: From 12 pregnant and 6 non-pregnant mares, 102 venous blood samples were taken, and their glucose (Glu), cholesterol (Cho), triglycerides (TG), total protein (TP), urea (Urea), Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), iron (Fer), calcium (Ca), phosphorus (P), and ferric reducing ability of plasma (FRAP) were assessed as biochemical variables. Also, red blood cells, hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin concentration, white blood cells, and platelets were all measured as hematological variables. Results: The levels of ALP, ALT, GGT, and P decreased significantly throughout gestation, while Ca, TG, Fe, and Glu levels increased. AST concentrations decreased in the second and third trimesters, whereas Cho levels increased in the first and second trimesters. Urea levels increased significantly in the third trimester, and FRAP showed significant differences at different stages of pregnancy. Mean corpuscular hemoglobin concentration was significantly lower in the first and second trimesters, and hemoglobin values were significantly lower in the second trimester. The mean value of white blood cell count was slightly higher in late pregnancy, while platelet values significantly increased throughout all trimesters. Conclusion: The study provides valuable information on the changes in hematological and biochemical parameters during pregnancy in Barb mares. These findings can be used as a reference for future studies on the reproductive physiology of this breed.

“…The increases in serum enzyme activities after parturition could have resulted from either decreased clearance or increased release of enzymes into plasma. A consistent change in serum AST activity was not recognized in pregnant mares in an earlier study, but AST activity in horses in late gestation was significantly lower than in barren mares 24…”
