Effects of Arginine Supplementation on Growth Performance, Serum Parameters, and Rumen Microbial Diversity in Fattening Altay Sheep Fed a Forage-Based Diet

This study was conducted to investigate the effects of dietary supplementation with rumen-protected arginine (RP-Arg) on growth performance, rumen fermentation parameters, microbial diversity, and blood physiological and biochemical indices in fattening Altay sheep. A total of 24 healthy, 6-month-old Altay male lambs were randomly assigned to three groups, with eight replicates per group. The control group received a basal diet, while the experimental groups were supplemented with either 0.50% o
