Abstract:
A method for growing pigs comprising feeding to pigs a first diet having an energy content in terms of total digestable nutrition (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, such that the pigs can access to either of said first and second diets ad libitum, the crude protein content in said second diet being higher than that of said first diet and the difference between the crude protein contents in said first and second diets being not less than 5% by weight, the lysine content in said second diet being higher than that of said first diet and the difference between the lysine contents in said first and second diets being not less than 0.5% by weight, said first and second diets containing 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.
