Abstract:
The Temperature-Humidity-Index (THI) has been developed as a marker of the ambient heat load placed on cattle. Animals from arid tracts commonly have combined effects of environmental changes incorporating ambient temperature and relative humidity. The THI is considered to be an excellent indicator of variations in physiological acidification parameters viz. plasma and urine bicarbonates and plasma and urine anion gap. The values of THI among ambiences varied significantly (p≤0.05) and humid-hot displayed maximum value. An interpretation was drawn from the data observation of THI that humid-hot ambience produced severe impact on the animals as compared to dry-hot ambience. Maximum levels of plasma and urine bicarbonate was observed during humid-hot ambiences. During humid-hot, the per cent variation in the value of plasma bicarbonate and urine bicarbonate were found to be maximum (+15.85) and (+85.95), respectively. According to the observations of research, in group A plasma bicarbonate and urine bicarbonate values were found significantly (p≤0.05) higher in pregnant dry cows than non- pregnant milch and pregnant milch cows. In group B, those values were significantly (p≤0.05) higher in multipara cows than the respective mean value of primipara cows.
The value of per cent variation of plasma anion gap was observed maximum (-15.42) during humid hot while the urine anion gap to be maximum (+40.68) during dry hot ambience. According to the observations of research, in group A plasma anion gap values were found significantly (p≤0.05) lower in pregnant dry cows than non- pregnant milch and pregnant milch cows. In group B, those values were significantly (p≤0.05) lower in multipara cows than the respective mean value of primipara cows, while the urine anion gap showed the reverse trend than that of plasma anion gap. Investigation revealed that the combined effect of temperature and relative humidity in terms of THI affect the acidification indicators, which alters the physiological levels of electrolytes in body.
