  • Detection and expression of heat stress gene in buffaloes: A potential solution to climate-proof bull semen

    Buffaloes are less tolerant to extremes of hot and cold, as compared to other breeds of cattle. Despite of its black skin which absorbs much heat, buffaloes only have one-sixth of sweat glands than a cow has. This explains their behavior of wallowing in muddy ponds or rivers on hot days. On the physiological level, buffalo semen production and its quality are believed to be affected by changing climates.

    Heat shock proteins (HSP) are known to help preserve the cell survival under adverse environmental conditions. One of the heat shock proteins being extensively studied is the HSP70, as it had been discovered to have the capability to protect the cells under heat stress thus suggesting its potential role during reproduction.

    As an effort to enhance fertility and reproduction in water buffaloes, this research aim to investigate the HSP70 level on various climates/seasons. It aims to come up with a combined method of assessing buffalo semen quality at the cellular and protein level. In the same way, it seeks to establish measures and management interventions to alleviate the detrimental effects of changing climates on bull semen quality and reproduction. Development of such technique can be used as a basis in determining candidate donor bulls for semen collection, cryopreservation and production purposes. Moreover, the development of this technique can be eventually operationalized across other livestock species.
