Reference intervals for selected hematological and biochemical variables in Hucul horses

Area of Science:

• Equine science
• Veterinary hematology
• Clinical biochemistry

Background:

• Hucul horses are a distinct, primitive breed from the Carpathian Mountains.
• Previous hematological and biochemical studies in this breed are lacking.
• Morphological differences have been noted compared to other primitive equids.

Purpose of the Study:

• To establish reference intervals for hematological and biochemical variables in Hucul horses.
• To compare these variables with those of other horse breeds.
• To provide a baseline for health assessments in Hucul horses.

Main Methods:

• Blood samples were collected from 168 Hucul horses.
• Standard hematological and biochemical analyses were performed.
• Nonparametric methods were primarily used for establishing reference intervals.

Main Results:

• Reference intervals for RBC, HGB, HCT, MCV, MCH, MCHC, WBC, and differential counts were determined.
• Established intervals for platelets (PLT) and mean platelet volume (MPV) were recorded.
• Reference ranges for biochemical markers including ALP, AST, GGT, total bilirubin, CPK, triglycerides, urea, creatinine, and serum amyloid A were defined.

Conclusions:

• Hematological and biochemical profiles of Hucul horses align more closely with hot-blooded breeds.
• The established reference intervals serve as a valuable clinical tool for Hucul horse health evaluations.
• This study provides crucial data for differentiating Hucul horses from other primitive equids.
