Effects of silybin supplementation on nutrient digestibility, hematological parameters, liver function indices, and liver-specific mi-RNA concentration in dogs

Hepatopathies are an important group of disorders in dogs where proper nutritional care is crucial. Supplementation with a hepatoprotectant like silybin can improve liver function and should not interfere with nutrient digestibility. The

EXP1 confirmed that silybin (whether pure or as a commercial hepatoprotectant) does not interfere with digestion which subsequently exerts no detrimental effect on dogs' health and metabolism. In EXP2, dietary supplementation with commercial hepatoprotectant containing silybin resulted in a decreased activity of serum liver markers, accompanied by a decrease in the concentration of liver-specific miRNA molecules. Liver function indices were consequently improved. Silybin supplementation can thus serve as an effective therapeutical tool in dogs with hepatopathies.

Nutrient digestibility was not affected by treatment in EXP1. Supplementation did alter the serum fatty acid profile, with no clinical relevance. The levels of liver markers such as ALT, AST and GGT significantly decreased. In EXP2, supplementation with commercial hepatoprotectant containing silybin improved liver function tests. A decrease was observed in liver serum markers such as ALT, AST and miR122 concentration. Conclusions: EXP1 confirmed that silybin (whether pure or as a commercial hepatoprotectant) does not interfere with digestion which subsequently exerts no detrimental effect on dogs' health and metabolism. In EXP2, dietary supplementation with commercial hepatoprotectant containing silybin resulted in a decreased activity of serum liver markers, accompanied by a decrease in the concentration of liver-specific miRNA molecules.
