[Glutathione peroxidase activity in whole blood and plasma of horses of different ages, sexes and different use].

The research article investigates the activity of the Glutathione peroxidase (an antioxidant enzyme) in the whole blood and plasma of horses. Differences were observed based on the horse’s age, sex, and usage/breed.

Introduction and Methodology

• The study tested GSH-Px (Glutathione peroxidase) activity in the blood and plasma in a total of 269 horses.
• The horses’ age, sex and usage or breed were factors taken into consideration in the examination
• The study also investigated if there’s any correlation with the identified values in blood and parameters such as hematocrit and hemoglobin content.

Results and Findings

• Trotters and riding horses recorded higher GSH-Px activities in plasma as well as in blood when compared to Thoroughbreds in training and yearlings.
• Thoroughbreds between the ages of three and six indicated higher GSH-Px activities than those aged between one to two years old.
• Colts (young male horses) and fillies (young female horses) did not show significant differences in GSH-Px activity.

Implications and Conclusion

• The research illustrates that the activity of the antioxidant enzyme, Glutathione peroxidase differs among horses depending upon their age, breed, and usage.
• It provides important insight for further research on equine health and nutrition, particularly in the way breeds, age, and purpose of the horse impacts the levels of this critical enzyme in the body.
• Additionally, the comparable GSH-Px activities between young male and female horses could lead to a better understanding of gender differences in equine biology, health, and nutrition.
