"To improve the efficiency of lean meat production, four experiments were carried out for seventy six heads of pigs from 1998 to 2000. First was the experiment on interaction between betain and the level of crude protein (CP). Second is the experiment on availability of betain for the replacement of metionine for growing pigs fed the diets with low CP. Third is the experiment on the effect of sesame-dregs for decreasing the fat in growing pigs. And fourth is the experiment on the valance between energy and content of lysine in the diets with low protein. The results obtained are summarized as follows: l)For only pigs fed the low CP diets supplemented amino acids, betain were effective on growth. On the other hand, the effects of betain on the decreasing of fat were only obtained for pigs fed the diets with high CP level. 2) Growth and fat thickness in the pigs fed the diets supplemented betain for the replacement of metionine were similar to that in the pigs fed the diets supplemented metionine. 3) The backfat thickness in pigs fed sesame-dregs instead of been-dregs decreased. 4) The growth and back fat thickness of pigs were controled by the ratio of content of lysine for the digestible energy."
