Since the economic is changing and new way of life is affecting the Mrabri community, it is essential to make the change ( since the change is happening anyway) to benefit the Mrabri(MRB) habitants in all areas especially in the health care. If the MRB could contact the Health care official and agriculture development official how to raise Pigs or any farm animal in a hygienic way , it will prevent animal diseases to spread to other farm animals , mean while you will raise animal in an effective cost reduction without spending in animal drugs nor to consume sick animal which I believe, the owner will sacrificed the sick animal for consumption before it get too late. The healthy set in animal farm raising does not mean to confine animal in a narrow area nor does it imply to have animal roaming around. There are lot of diseases in pigs that can transferred to human, many of those are parasites.
It is wisely to work with the agriculture department in how to manage animal farming. There are plenty of good people out there at the government level who have knowledge to help and mostly free of charge.
Change is happening, it is at your farsighted how to help to improve your community without being trapped into the private selfish individual, if you look at your community as a whole not to any individual benefit.
