Of course there are humane ways to raise livestock. Unfortunately the most humane ways also cost the most money and let's face it, money - and not compassion - is the bottom line for most of those in the livestock business.
With respect to veal, the very reason it tastes good to you is
because it has been treated cruelly. I don't know how much you know about veal other than that the end product tastes good, but I am a firm believer that people should have a working knowledge of where their food comes from and how it is processed before they put it into their mouth. To me it is the same principle as having a working knowledge of how one's government functions before voting.
Here is some information about veal; if you can say that you have no problem with other humans causing a calf to suffer it's entire life because that process makes it taste good for the few minutes you spend eating it, then there is no way I can argue with your position on this issue:
...Male calves are taken from their mothers shortly after birth. ... Most are destined for the veal crate.
Solitary Confinement
The veal crate is a wooden restraining device that is the veal calf's permanent home. It is so small (22" x 54") that the calves cannot turn around or even lie down and stretch and is the ultimate in high-profit, confinement animal agriculture.(1) Designed to prevent movement (exercise), the crate does its job of atrophying the calves' muscles, thus producing tender "gourmet" veal.
...
The calves are generally fed a milk substitute intentionally lacking in iron and other essential nutrients. This diet keeps the animals anemic and creates the pale pink or white color desired in the finished product. Craving iron, the calves lick urine-saturated slats and any metallic parts of their stalls. Farmers also withhold water from the animals, who, always thirsty, are driven to drink a large quantity of the high-fat liquid feed.
Because of such extremely unhealthy living conditions and restricted diets, calves are susceptible to a long list of diseases, including chronic pneumonia and "scours," or constant diarrhea. Consequently, they must be given massive doses of antibiotics and other drugs just to keep them alive. ... The calves often suffer from wounds caused by the constant rubbing against the crates.
...
About 14 weeks after their birth, the calves are slaughtered. The quality of this "food," laden with chemicals, lacking in fiber and other nutrients, diseased and processed, is another matter. The real issue is the calves' experience. During their brief lives, they never see the sun or touch the Earth. They never see or taste the grass. Their anemic bodies crave proper sustenance. Their muscles ache for freedom and exercise. They long for maternal care. They are kept in darkness except to be fed two to three times a day for 20 minutes. ...
