Popis:	As a methyl group donor and organic osmolyte, betaine has been widely used in livestock production, but the antioxidant defence properties of betaine in lambs have not been determined. The objective of this study was to investigate the effect of dietary betaine and rumen-protected betaine (RPB) supplementation on the growth performance and antioxidant status of lambs. A total of sixty male Hu sheep (approximately 30 kg body weight) were randomly assigned into five treatments and fed basal diets (Con group), basal diets with 2.2 g/d betaine supplementation (B-2.2 group), basal diets with 2 g/d RPB supplementation (RPB-2 group), basal diets with 4 g/d RPB supplementation (RPB-4 group), and basal diets with 6 g/d RPB supplementation (RPB-6 group) for 70 d. After the feeding experiment, the antioxidant indexes in the serum, Longissimus dorsi (LD) and liver were measured. Dietary supplementation of RPB increased the average daily gain (ADG) and decreased the feed-to-gain ratio (F/G) of lambs (P
