Beef Ban

Arguments in Favour:

• Article 48 of the Constitution of India states that "The State shall endeavour to organise agriculture and animal husbandry on modern and scientific lines and shall, in particular, take steps for preserving and improving the breeds, and prohibiting the slaughter, of cows and calves and other milch and draught cattle". The recent legislation brought by the Maharashtra government which seeks to ban beef is in line with the provisions of the constitution.
• Cow slaughter was already banned considering the religious sentiments attached with it. People involved in meat industry didn't have problem with it then. Then why are they crying afoul now over the proposal of banning trade of meat of bulls and bullocks? It is worth mentioning here that pork is banned in Muslim nations.
• Beef is essentially red meat and not a desirable ingredient in a high-protein diet as well. 

Against the move:

• Beef offers cheap protein to the poor suffering from malnutrition.
• Livelihood of lakhs of people depend on meat industry.
• The move would aggravate the distress of farmers as their alternative source of income has been done away with. Earlier farmers could sell off their aged cattle when crops failed.
• There are old animals who have given up their milk production and roam about roads causing problems to commuters. Now that the beef has been banned, they would become a liability.
• Strangely,when leather industry doesn't have any restrictions on using cow-derived products, then why ban beef?
• Restaurants would lose a lot of International tourists. Prices of other meat products would also rise up.

Conclusion: 

Apparently, the ban is religiously motivated aimed at scoring political points. It does not augur well for a democracy where minority choices ought to be respected.
