Reference Ranges for Hematological and Biochemical Profile of Martina Franca Donkeys
2020
The Martina Franca donkey (MFd) is one of the largest Italian donkey breeds, considered as endangered breed. To support the conservation strategies, the knowledges about physiologic hematological parameters of MFds are needed. The aims of the study were to determine reference value for hematological and major serum parameters in a population of healthy MFds and to estimate the influence of age on these parameters. Seventy-eight clinically healthy MFds (14 males and 64 females) in different age (foals; young animals and adult animals) were enrolled. Red blood cells count (RBC), hematocrit value (HCT), hemoglobin concentration (HGB), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), hemoglobin concentration distribution width (HDW), RBC distribution width (RDW), total white blood cell (WBC), WBC differential count for neutrophils, lymphocytes, monocytes, eosinophils and basophils , platelets (PLT), mean platelet volume (MPV), platelet volume distribution width, and plateletcrit (PCT) were analyzed. The biochemistry panel included: aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), total serum protein (TP), albumin (ALB), cholesterol (CHOL), triglyceride (TGL), blood urea nitrogen (BUN), creatinine (CREA), glucose (GLU), Ca2+, phosphorus, Na+, Cl-, K+ and Mg2+. The effect of age on hematological parameters was investigate using One-way ANOVA test. Age of donkeys not influences total WBC, HGB, HCT, platelets count and MPV, and PCT (P > 0.05). Some leucocytes populations as eosinophils, monocytes and basophils showed variations age-linked (P< 0.05). RBCs count, RDW and HDW decrease with age whereas MCV, MCH increase. The Na+, K+, Cl-, Ca2+, phosphorus, ALP, GGT, CREA, GLUC, and CHOL decrease with age (P < 0.05) while AST and TP showed an increase with aging (P < 0.05). ALB reaches the lowest values in young donkeys and returns to values of foals in older animals (P < 0.05). Finally, it was not found difference among groups for BUN and TGL (P < 0.05). The results suggest how even for the MFd breed, age is a variable that affects different hematological and biochemical parameters. Compared to other donkey and horses, the MFd breed showed some differences that clinicians involved during conservation strategies need to be consider.
