This study was conducted to evaluate the impact of age (from birth to three months) on serum metabolites and minerals in crossbred calves. The research was carried out on six apparently healthy crossbred calves (aged 0-3 months) of similar physiological status. Blood samples were collected from the experimental animals on 0, 3, 7, 10, 15, 30, 45, 60, 75 and up to 90 days age of calves. | Assessment of age effect on serum metabolite and mineral profile of crossbred calves
