Abstract
There are conflicting data on the exact Mn requirements of pigs for proper growth, skeletal development land reproduction (Underwood, 1971). Johnson (1940), reported that 0.3 ppm Mn in the diet supported satisfactory growth rates but that the tissue Mn levels were significantly depressed. He later showed that pigs grew well from weaning to market weight 'On rations containing 7 to 10 ppm Mn (Johnson, 1944). Keith et al. (1942), using a high corn (maize) ration containing 11 to 14 ppm, found tJha.t the growth of pigs was not impaired but skeletal development was poor.
