Effects of Phytosterol Licking Blocks on Growth Performance, Serum Biochemical Parameters, and Rumen Fermentation in Tibetan Sheep

Phytosterols are plant-derived natural compounds which resemble in structure with cholesterol. It has been demonstrated that phytosterols significantly affect growth regulation and antioxidant capacity in poultry and pigs; however, their role in ruminants remains unclear. This study aimed to investigate the effects of phytosterol lick blocks on growth performance, serum biochemical and rumen fermentation parameters in Tibetan sheep.
