Dairy has clues for cold chain

Dairy has clues for cold chain

Amid concerns that a Covid-19 vaccine would require an efficient, countrywide cold chain infrastructure, the dairy industry could offer some answers to policymakers and public health professionals. The industry records almost 8 crore artificial inseminations across the country annually. The process involves collection of semen from elite bulls in 56 bull stations, which is frozen in vials or ‘straws’, and transported in liquid nitrogen containers (at minus 196 degrees Celsius) to dairy farmers across the country. “The most crucial aspect of the artificial insemination cold chain is its reliability (ensuring viability of the sperms from the point of semen extraction to insemination into a female bovine) and reach (to the distant interiors," said Rajiv Mitra, CEO of Prabhat Dairy based in Ahmednagar, Maharashtra.
