Serum proteinogram of the Campeiro horse

Abstract

The aim of this study to measure the fractions of the total serum proteins of the Campeiro horse and identify the influences of biological variants. Blood samples were taken in 138 horses of the breed Campeiro for measuring the concentration of total serum protein by the biuret method. Serum concentrations of protein fractions were measured by electrophoresis using agarose gel. Groups were formed according to age, sex and reproductive condition. The average values of serum fractions: albumin (2.85±0.36g/dl), alpha 1 (0.28±0.11g/dl), alpha 2 (0.26±0.08g/dL) beta 1 (0.57±0.15g/dl), beta 2 (0.89±0.28g/dL), gamaglobulinas (1.86±0.34g/dL), albumin/globulin ratio (0.75±0.18) and 2.5% percentile and 97.5% had slight differences in relation to the reference interval proposed for the species. They observed higher values of alpha 1 and 2 globulins in the group from that had six to eight years old and gammaglobulins in group above 13 years old. Serum protein concentrations were similar in horses and mares and between non-pregnant and pregnant. Sex and pregnancy status did not affect serum proteinogram. Alpha and gammaglobulins have higher values as the age increases. Serum proteinogram of Campeiro horses shows variations that have to be considered in the interpretation of laboratory tests.

“…The breed has been used for farm work, pleasure riding and in various types of equestrian sports (Gonçalves et al 2012, Abrantes et al 2015. The Campeiro horse is a locally adapted breed that has developed through natural selection in the Serra Catarinense, region of southern Brazil, and has its own characteristics related to adaptation to the environment (Souza et al 2021, Souza et al 2019, Souza et al 2018, Souza et al 2016) (Figure 1B). Therefore, in addition to desirable characteristics for riding, such as the marcha gait, it constitutes an important genetic patrimony for animal breeding programs (McManus et al 2005).…”
