Free movement of cattle across Bangladesh-India border

Beef is in high demand in Bangladesh. But its price is very low in India.
Due to religious sentiment, India can't export cattle. So the farmers of India are not getting fair price for their cattle. It will go in the interest of Indian traders if BSF allows free movement of cattle from India to Bangladesh. They will get higher price for their surplus cattle. Consumers of Bangladesh will also be benefitted as beef is now very dear here.
So I suggest that both BSF and BGB should develop an understanding that they will allow free movement of cattle between the two countries throughout the year. Loss of custom duty on both sides will be negligible but benefit to Bangladeshi consumers and Indian farmers will be immense.
Will the authorities concerned ponder over this?
