Does raising pigs depend on skill?

Is the pig industry simple? Do you have a good income? I chatted with some friends around this topic. They told me that the pig industry has high risk and low income. But as far as I know, when I was at home at school, some neighbors raised fat pigs, while some pigs always got sick and would die two today and one tomorrow. In the end, not only did not earn, but also will lose a lot of money! What on earth made our pig babies die unexpectedly? As far as I know, pigs are most susceptible to classical swine fever, blue ear, circovirus, split hoof, cough, asthma and smallness (this is what I read in books), but how to deal with these viruses in practice? Or is there any skill in raising pigs to save the babies from their difficulties? With these problems I have to go to further understanding, lest the future road of raising pigs is not easy to walk! Friends, if you have any opinions, please give us your advice. Waiting! Last year and this year were good.
