“Including L-lysine reduces the CP content of the diet and requires less nonsolar energy to deliver adequate standardized ileal digestible lysine than simply feeding soybean meal.”
“Each 1-percentage-point increase in CP in the wheat middlings was associated with .0235 (r2 = .61) and 2.1 (r2 = .39)-percentage-point increases in lysine and NDF, respectively.”
“No amino acid seemed to be limiting for calves greater than 20 wk … (Trial 4) when daily CP intake was 4.1 g/kg BW, but lysine was … when CP intake was restricted to 3.0 g/kg BW when … were more than 17 wk of age (Trial 5).”
“Gilts fed increased digestible lysine had greater CP accretion from 34 to 55 kg (linear, P < .01), 55 to 72.5 kg (linear, P < .05; quadratic, P < .10), and from 34 to 72.5 kg (quadratic, P < .05).”
