Serum Pepsinogen, Rathi Female Calves, Heifers and Cows.

An investigation was carried out to assess physiological strategies in Rathi female calves, heifers and cows from arid tracts implying modulations in serum pepsinogen activity during various ambiences. The whole experiment was divided into moderate, extreme hot, rainy and extreme cold ambiences in the arid tract. Blood samples were collected from Rathi cattle belonging to Bikaner district, Rajasthan, India. The cattle were divided into calves, heifers and cows. The overall mean value of serum pepsinogen during moderate ambience was 150.00±2.10 mU tyrosine, which was obtained from 300 Rathi cattle incorporating calves, heifers and cows. The overall mean values of serum pepsinogen were significantly (p≤0.05) higher during extreme hot, rainy and extreme cold ambiences in comparison to moderate mean overall value. During rainy ambience, the per cent variation in the value of serum pepsinogen was found to be maximum (+147.33). Based upon results, it can be reiterated that impact of rainy ambience was enormous on overall serum pepsinogen value followed by extreme hot and cold ambiences. This was irrespective of physiological states. Among physiological states, cows had higher overall value of serum pepsinogen as compared to overall value of calves and overall value of heifers during moderate conditions. This pattern was maintained during all the three extreme ambiences with respective remarkable elevations during rainy ambience. In order to evaluate the magnitude of impact of ambiences and physiological states on serum pepsinogen, per cent variations were monitored. Overall value revealed highest per cent variation during rainy ambience as compared to extreme hot and cold ambiences indicating that serum pepsinogen was modulated maximally during rainy ambience followed by extreme hot and cold. Among calves, heifers and cows, per cent variations were highest in overall values of calves followed by heifers and cows. This pattern was maintained in all the three extreme ambiences, magnitude being greater, respectively during rainy ambience. These patterns indicated that calves were affected most and rainy ambience had greater impact on the animals. Pattern of per cent variation revealed that among calves, calf-yearling transition group showed maximum modulations. Pre-pubertal heifers were affected most in heifer group showing maximum per cent variation during rainy ambience. Among cows, non-pregnant milch and primipara divulged greater effect as compared to other members of respective group. Rainy ambience showed maximum temperature humidity index values. Extreme ambiences affected the abomasal functions of the animals
