ABSTRACT

 

In order to observe, the effect of temperature variability on physiological, hematological and biochemical profile, six each of growing and adult Sahiwal cattle were selected from cattle yard of NDRI, Karnal, India. Experiments were conducted during hot humid (32.00±0.30°C and RH 86.30 %), winter (11.0±0.30°C and RH 85.00%), spring (23.00±0.50°C and RH 45.00%) and summer (39.00±0.60°C and RH37.70 %) seasons. The fluctuations were observed in RR and RT of growing and adult Sahiwal cattle during different seasons in morning. The magnitude of increase in RR and ST was found to be higher during hot humid season compared to summer over the spring season. All the physiological parameters showed significantly higher values during afternoon compared to forenoon values in growing and adult Sahiwal cattle. Hematological parameters viz. Packed Cell Volume (PCV) and hemoglobin (Hb) levels were higher during winter season than other seasons, whereas WBC levels were lower during summer as compared to spring season in both groups of animals. Higher (P<0.05) levels of cortisol was found during summer (8.91ng/ml) over spring (1.92ng/ml). The plasma enzymes viz ALT, AST, ALP and LDH increased (P<0.05) during summer over spring season. Different physiological and biochemical parameters showed positive correlation (P<0.05), whereas hematological parameters showed negative correlation (P<0.05) with Tmax and Temperature Humidity Index (THI). Results of the present study indicated significant deviations in different physiological, hematological and biochemical profile different seasons in both growing and adults Sahiwal cattle. But the deviations in these parameters were more pronounced in growing animals than adult cattle during afternoon than morning. Therefore, the growing animals need extra protection from extreme heat.
