    摘要: A novel method for growing pigs by which excess intake of nutritions is prevented while attaining sufficient growth, as well as a feed used therefor, is disclosed. In the method for growing pigs according to the present invention, a first diet having an energy content in terms of TDN of not less than 72%, a crude protein content of 8% by weight to 23% by weight, and a lysine content of 0.3% by weight to 1.5% by weight, and a second diet having an energy content in terms of TDN of not less than 72%, a crude protein content of 13% by weight to 28% by weight, and a lysine content of 1.0% by weight to 2.0% by weight are fed such that the pigs can access to either of said first and second diets ad libitum. The crude protein content in the second diet is higher than that of the first diet and the difference therebetween is not less than 5% by weight, and the lysine content in the second diet is higher than that of the first diet and the difference therebetween is not less than 0.5% by weight. The first and second diets contains 30-90 parts by weight of isoleucine, 31-91 parts by weight of total of methionine and cysteine, 33-98 parts by weight of threonine, and 10-29 parts by weight of tryptophan per 100 parts by weight of lysine.
