You may rear or farm them for your food, but it is absolutely inhumane to subject them to unnecessary abuse and cruelty. This is why Muslims practise their animals to be slaughtered throught the Halal way, where animals are calmed down, prayers offered for them before they are slaughtered. This was explained to me by a Muslim friend of mine. I still believe animals have souls. When I was a kid, our family used to live in one of those landed property pre-war Peranakan bunglows. We used to rear our own chickens, ducks, had a few goats, two cats, three dogs , a piglet and a lotus pond where we reared fishes like the sheng yu and the soon hock. Even as a kid, I gave them all each a name. Thus we had our own supply of eggs, goat's milk, lotus seeds and fresh water fish. We also have a plot of land where we planted our own vegatables and about 60 pots of orchids. When we have to slaughter one of them for an occassion, I felt very sad, and so did my grandma. Thus I grew up having these connection with animals. Infact be it a plant or an animal, they are all just lives to me. Even when a plant of mine died due to my own forgetfullness to water them, I feel sad for them due to my own negligence. Really don't understand why should that guy, just punch and kick the calf. That cruelty really doesn't makes sense.
