Abstract

The objectives of this study was to investigate, for the first time in Medziphema, the effects of seasonal variation on physiological and hormonal profile as indicator for physiological status evaluation in crossbred cattle. The study was conducted on ten which were organized according to seasons. The mean THI values for calendar year 2022 were calculated and divided into three seasons such as spring 67.72 (January to April), summer 78.08 (May to August), and winter 72.66 (September to December). Blood samples were collected twice times during this study period. The data with respect to changes in physiological and hormonal included mean rectal temperature (RT), pulse rate (PR), respiration rate (RR), skin temperature (ST) and hormonal profile tri-iodothyronine (T3), thyroxine (T4), plasma cortisol levels. The recorded were mean significantly (P≤0.05) higher summer season rectal temperature (RT), pulse rate (PR), respiration rate (RR), skin temperature (ST) higher during summer as compared to other seasons and as well as tri-iodothyronine (T3) thyroxine (T4), plasma cortisol levels, respectively it was higher during summer season as compared to spring, winter seasons. The changes in physiological and hormonal profile of dairy crossbred cattle in response to different climates have affected on production system. The capability of an animal to with stand the rigors of climatic stress under hot conditions has been assessed physiologically by means of changes in body temperature, respiration rate and pulse rate and skin temperatures. Therefore, this study might be useful for assessment providing base line information on hormonal profile status of dairy cattle. The results indicated that blood was positively correlated with temperature of the body parts. This study concluded that, summer stress of physiological changes in crossbred cattle during the summer season cause stress, which is a challenge for dairy farmers, which affects the production in summer season.

Conclusion

On the basis of this study, it can be concluded indicated that highest as tri-iodothyronine (T3) thyroxine (T4), plasma cortisol levels during summer and spring season due to heat stress climatic condition. RT, PR, RR and ST highest during summer season due to higher stressful temperatures and THI period. This variation in higher levels parameters related to changes in ambient temperature, relative humidity and THI, although within physiological and hormonal parameters for crossbred cattle. Therefore, we can claim that the seasonal changes can impact the metabolic activates.
