Abstract : Twenty-four growing male buffalo calves one year of age; 88.54 ± 3.81 kg average body weight were divided into three comparable groups I, II and III on the basis of their body weight BW in a completely randomised design to study the effect of long term feeding of ammoniated wheat straw AWS and hydrochloric acid treated ammoniated wheat straw HCl-AWS on blood biochemical changes. The animals were offered a concentrate mixture CM along with wheat straw WS, ammoniated wheat straw AWS 4% urea at a 50% moisture level and hydrochloric acid treated ammoniated wheat straw HCl-AWS 4% urea at a 50% moisture level and HCl added to trap 30% of NH3 evolved in groups I, II and III, respectively for an average daily gain ADG of 500 g. All the diets were made iso-nitrogenous by preparing three types of concentrate mixtures of different CP levels. The blood was collected from the jugular vein randomly from three animals of each group initially after 8 months post feeding and subsequently after two months interval up to 14 months of experimental feeding. Due to urea ammoniation, the CP content of WS increased from 3.66 to 8.51 and was further increased to 11.35 due to the addition of HCl during urea-ammoniation of wheat straw. The cumulative period mean plasma glucose values mg %, in group II 53.13 were significantly P < 0.001 higher than those in groups I 48.44 and III 50.60. The cumulative period mean values of serum albumin and globulin g % were not significantly different and were comparable among the groups I 3.33 and 3.06, II 3.53 and 2.97 and III 3.49 and 2.94. The cumulative period mean values of serum albumin: globulin ratio and total protein values were not significantly different among the different groups. Serum urea and creatinine values were significantly P < 0.001 higher in group III 58.66 and 2.24 as compared to groups I and II. The cumulative period mean values of serum alkaline phosphatase ALP KA units did not differ significantly, but serum glutamate pyruvate transaminase SGPT and glutamate oxaloacetate transaminase SGOT values units*mL-1 were significantly P < 0.001 higher in groups II and III than in group I. The cumulative period mean values of T3 ng*mL-1 did not differ significantly among the groups, but T4 values were significantly P < 0.001 higher in group III 22.74 than in groups I 21.41 and II 20.89, respectively. Since the mean values of all the blood parameters were within the normal range, it may be concluded that feeding of ammoniated wheat straw treated with and without HCl to growing male buffalo calves for fourteen months has no adverse effect on the blood biochemical parameters.
