Abstract:

This study was conducted to investigate the effects of resveratrol (RES) and sanguinarine (SAG) on the growth performance and serum biochemical indexes of 2-6 months old calves. Fifty-four female Holstein calves of 5 days old with average body weight of 42 kg were randomly assigned to 3 groups with 18 calves in each group. Calves were fed one of the following diets:a milk replacer (MR) as the basal diet (MR group), a basal diets supplemented with SAG (0.05 mg·(kg BW)-1, SAG group) or a basal diet supplemented with RES (4 mg·(kg BW)-1, RES group). Calves were measured for body weight and body size on 56, 90, 120, 150 and 180 days of age. Blood was collected on 60 and 180 days of age for detecting serum biochemical indexes. The results showed that:1) Compared with MR group, RES supplementation significantly increased the body weight of 180 days old calves (P<0.05). The body weight of 180 days old calves in SAG treatment had a trend to increase (P=0.081 2); 2) In body size, SAG supplementation significantly increased the body height of 150 and 180 days old calves (P<0.05), and hip height of 180 days old calves(P<0.05); 3) Compared with MR group, RES and SAG supplementation significantly decreased serum FFA and INS concentrations of 60 days old calves (P<0.05); RES supplementation significantly increased serum GH, EGF and IGF-Ⅰconcentrations of 60 days old calves (P<0.05); SAG and RES supplementation significantly increased IgA concentrations of 60 days old calves (P<0.05); SAG and RES supplementation had no significant effect on IgG (P>0.05); Serum MDA concentration of 60 days old calves in SAG treatment group were higher than that in MR group (P<0.05). RES and SAG supplementation had no significant effect on serum SOD, GSH-PX and T-AOC concentrations of calves (P>0.05). In conclusion, the addition of RES and SAG in diets increased the body weight and body height of 180 days old calves, respectively, and improved the serum antioxidant indexes of calves.
