No, he will rather sell the cow to get some money or donate it do get blessings but will not kill it for food.
Read my question again ............ this time carefully and try to understand where I am going to go with this. It would have been better if you had left it for Adil to answer you won't like the comparison I would draw from your response.
Selling cow in drought? And even if he gets the money what would he do with the money? Money doesn't produce food it buys food .......... and my scenario is non availability of food other than his cow only.
