“…Pigs fed the 14% C-S diet gained 0.18 kg/day faster than pigs fed the 10% HL diet. Numerous other workers have shown that increasing the level of dietary protein increases growth rate for barrows and/or gilts (Jensen et al, 1955;Baker et al, 1967;Clawson, 1967;Jurgens et al, 1967;Lee, McBee and Howath, 1967;Davey and Morgan, 1969). However, Gilster and Wahlstrom (1970) reported a reduction in gain of only 0.06 kg/day for pigs fed high lysine corn in a sequence of 12 to 10% protein compared to normal corn in a sequence of 16 to 14% protein.…”
