- Abstract
The experiment was conducted to investigate the effect of different combinations of complex amino acids and multivitamin additives on serum biochemical indices and immunoglobulin content of finishing beef cattle. Twelve healthy finishing Simmental crossbred cattle with similar age and body weight of (485.82±12.50) kg were randomly divided into four groups with three replicates per group and one cow per replicate. Control group beef cattle were fed with basic diet, group A was supplemented with 5 g/kg arginine + 15 g/kg glutamine in the basal diet, group B was supplemented with 5 g/kg arginine + 70 mg/kg multivitamin, group C diet was supplemented with 15 g/kg glutamine + 70 mg/kg multivitamin. The experiment lasted for 45 d. The results showed that the content of total protein, globulin, total bilirubin, total bile acid, triglyceride, creatinine, urea nitrogen and magnesium in serum of beef cattle in group A were significantly higher than those in control group (P<0.05). The content of total protein, globulin, triglyceride, urea nitrogen and inorganic phosphorus in serum of beef cattle in group B were significantly higher than those in control group (P<0.05). The content of total protein, globulin, total bilirubin, urea nitrogen and magnesium, and the activities of gamma-glutamyl transaminase, alkaline phosphatase, total bile acid, creatine kinase and amylase in serum of beef cattle in group C were significantly higher than those in control group (P<0.05). The activities of alanine aminotransferase and the contents of cholesterol and glucose in serum of beef cattle in experimental groups were significantly lower than those in control group (P<0.05). The content of immunoglobulin M and immunoglobulin A in serum of beef cattle in group A were significantly higher than those in other groups (P<0.05). The study indicates that dietary supplementation of complex amino acids and vitamins has certain effects on blood biochemical indexes, and complex arginine + glutamine could increase body immunity of finishing beef cattle.
