An experiment was conducted to study the effect of two housing systems on haematological parameters in buffaloes. Twelve buffaloes were selected and randomly divided into two equal groups. Animals of group A were housed in shed with net and animals of group B in shed without net. The experiment was conducted for a period of three months. Blood samples were aseptically collected fortnightly and were analysed for haematological studies. The mean values for Hb, TEC, TLC, PCV,

MCHC and Neutrophil were 8.49 + 0.52 g/dl, 5.54 ± 1.05 (106/cmm), 27.45 ± 0.44, 31.15 ± 0.66 (%) and 40.99 ± 1.34 (%),

respectively, which was nonsignifi cantly higher than the values of 8.20 ± 0.80 g/dl, 5.22 ± 0.66 (106/cmm), 27.00 ± 0.58 (%), 30.35 ± 0.32 (%) and 39.96 ± 0.66 (%), respectively. Whereas, the values of MCH, lymphocyte, eosinophil and monocyte were 15.26 ± 1.06 (µµg), 55.33 ± 0.44 (%), 2.32 ± 0.45 (%), and 1.69 ± 0.69 (%); respectively, which were non signifi cantly lower than the values of 15.72 ± 0.85 (µµg), 55.56 ± 0.61 (%),3.19 ± 0.05 (%), and 2.03 ± 0.84 (%), respectively in group A as compared to group B. However, WBC count (13.75 ± 0.56 (103/cmm) were signifi cantly (P<0.01) higher than the value of 10.58 ± 0.42 (103/cmm) and MCV (49.45 ± 0.21, µ3) were signifi cantly (p<0.05) lower than the value of 51.85 ± 0.45 (µ3) in group A and group B, respectively. For statistical analysis, student‘t’ test was applied.
