Summary
Recent research with growing pigs has shown that vitamin E may be deficient in some corn-soybean meal diets. Some possible reasons why vitamin E deficiencies are being experienced today are that fewer pigs are fed on pasture, which is a good source of vitamin E; more corn is being picked wet and then artificially dried, which can destroy vitamin E; and the presence of a low selenium content of corn.
Copper has been shown to produce a growth response similar to antibiotics when it is fed at levels of 125 to 250 ppm. the study reported herein was conducted during the winter of 1969-70 to study the effects on growing-finishing swine of supplementing diets with vitamin E, copper, tylosin and combinations of these ingredients.
