To Compare the Effect of Different Shade Materials on the Physiological and Biochemical Variables in Buffalo Calves in Summer Season

Abstract

The present studies was carried out for a period of 120 days during summer season to see the effect of different shade materials on the performance of buffalo calf. Twenty four buffalo calves were selected for study and divided into 4 groups (6 calves in each group). The different groups of calves were studied under different roof materials as followed: asbestos roof (T1), Pre painted CGI Sheet roof (T2), thatch with polythene shading roof (T3): galvanized iron sheet roof (T4). The respiration rate (per minute) at 9:00 AM was 23.31±0.29, 22.76±0.09, 23.00±0.03 and 23.23±0.24 whereas at 2:00 PM was 43.03±0.1.62, 42.35±1.37, 35.00±1.16, 43.40±1.69 for T1, T2, T3 and T4, respectively. The results revealed that the respiration rate of calves at 2:00PM was significantly (P<0.05) higher than respiration rate at 9:00 AM in all the groups throughout the experiment. Respiration rate of T3 showed significant difference from T1, T2 and T3. The rectal temperature at 9:00 AM was 39.57±0.01, 39.76±0.07, 39.26±0.03 and 39.72±0.08 whereas at 2:00 PM was 39.66±0.03, 39.66±0.06, 39.10±0.04 and 39.71±0.04^oC for T1, T2, T3, and T4, respectively. The overall rectal temperature of T3 showed significance difference form all other groups. The overall haemoglobin concentration of buffalo calves were 9.42±0.31, 9.62±0.23, 11.02±0.30 and 9.35±0.22 g/dl for T1, T2, T3 and T4 group, respectively. The overall haemoglobin of T3 (11.02±0.30 g/dl) was shown significantly higher (P<0.05) than T1, T2 and T4 during the experiment.
