The purpose of this study was to investigate the effects of Tongmai granule residue (TGR) on the growth performance, apparent nutrient digestibility, blood biochemical parameters, and rumen fermentation in Doper x Small Tail Han hybrid sheep. Twenty-four healthy female lambs (6–7 months of age; 29.64 ± 1.80 kg initial body weight) were randomly divided into 3 groups and fed for 75 days. The control group was fed a commercial concentrate and the other groups were fed diets supplemented with 10% and 15% TGR respectively. Dietary 15% TGR supplementation decreased average daily gain, apparent digestibility of neutral detergent fiber, but increased the feed conversion ratio, apparent digestibility of crude fat and organic matter in lambs (P P < 0.05). Dietary supplementation of 10% and 15% TGR significantly increased serum high density lipoprotein cholesterol (HDL-C) content on day 15, IgG content on day 30, and IgA content on day 60 of the feeding period (P P P P P |
