The study found that feeding milk thistle seed cakes can have positive effects on the health of horses, especially in terms of liver diseases and antioxidant effects. Significant differences were detected in the biochemical markers of the experimental group, indicating the potential benefits of milk thistle in equine nutrition.
Simple Summary The use of milk thistle (Silybum marianum) is considered a safe phytogenic additive in animal nutrition. The aim of this study was to monitor the influence of feeding with milk thistle seed cakes included in the usual feed dose and to detect the effect on biochemical indicators of equine plasma. Milk thistle has been known for its positive effects on the liver (in liver diseases) and the antioxidant effects. Milk thistle seed cakes were fed as part of a normal feed dose in this study. Statistically significant differences were found out between the experimental and control groups of the horses. The significant values of the non-specific liver enzyme AST (aspartate transaminase) were determined in the experimental group. Statistically significant differences were detected after the exposure of the horses to physical exercise, especially for the values of cortisol, NEFA (non-esterified fatty acids), and inorganic phosphorus. Our results suggest that the feeding of milk thistle seed cakes can have a positive effect on the health of horses. Veterinarians can recommend milk thistle for the treatment of equine liver disease and laminitis. Milk thistle seed cakes were fed in the range of normal feed doses in this study. The milk thistle seed cakes were fed (twice a day) to the experimental group of the horses (n = 5) and biochemical blood markers (TP, Albumin, ALT (alanine transaminase), AST (aspartate transaminase), ALP (alkaline phosphatase), GGT (gamma-glutamyltransferase), Bilirubin, Cholesterol, HDL (high-density lipoprotein), LDL (low-density lipoprotein), TAG (triacylglycerol), BHB (beta-hydroxybutyric acid), NEFA (non-esterified fatty acids), creatine kinase, creatinine, Urea, GSH-Px (glutathione peroxidase), TAS (total antioxidant status), lactate, glucose, cortisol, Ca, Pi) were monitored. The control group of horses (n = 5), bred and trained in the same conditions, was used for comparison. The control group received the entire feed dose as accepted by the horses in the experimental group before the beginning of the experiment. The aim was to find out whether the preparation of milk thistle seed cakes could have positive effects on the health of the horses. All ten horses received one feeding form before the beginning of the experimental monitoring. All horses were exposed to heavy physical exercise (regular combined driving training) after 56 days of milk thistle seed cakes feeding (up to 400 g/day). Three blood samples were taken (before physical exercise; about 15 min and 60 min after physical exercise). Significant differences (p < 0.05) were detected in the values of AST, NEFA, cortisol and Pi in the experimental group. The exercise effect was detected in the values of albumin, lactate, cortisol, NEFA, and calcium. Our results suggest that the feeding of milk thistle seed cakes could have a positive effect on the health of the horses.
