Influence of +110, +220 and +330 mEq/kg of dry matter (DM) dietary cation anion difference (DCAD) on growth performance of growing male buffalo calves was examined in a randomized complete block design. Three DCAD diets were randomly allotted to three groups, ten calves in each group. A linear increase in nutrient intake was recorded with increased DCAD level. However, digestibilities of nutrients remained unaltered across all diets. Calves fed +330 DCAD diet had higher nitrogen balance than those fed +110 DCAD diet. Blood pH and serum HCO3 increased with increased DCAD level. Serum chloride was high in calves fed +110 DCAD diet, while serum (Na+K)−(Cl+S) increased linearly with increased DCAD level. Serum calcium increased with decreased DCAD level while serum magnesium and phosphorus remained unaffected. Ca balance remained unaltered by calves fed varying level of DCAD. Urine pH increased with increased DCAD level. Calves fed +220 and +330 DCAD diets gained more weight than those fed +110 DCAD diet. In conclusion, increased DCAD level not only increased dry matter intake but also weight gain in growing buffalo calves. © 2007 Elsevier B.V. All rights reserved.
