[Effect of various amounts of lysine and methionine on pigs]

The influence was experimentally studied of different lysine and methionine amounts in pig rations on gain, blood picture and some blood serum biochemical indexes. A 95 per cent gain was recorded when 0.14 per cent Bulgarian lysine was added to the basal ration as against the group whose ration was supplemented by 0.20 per cent crystal imported lysine. Groups administered toxic lysine and methionine doses showed minimal gain or none. Blood serum Ca amount nearly doubled for groups showing excess of dietary lysine while P and M levels for the same groups appreciably dropped. Blood sugar level went up in methionine toxicosis.
