Estimating the optimal threonine requirement for 25–50 kg pigs fed a mixture of soluble and insoluble dietary fibre

Estimating the optimal threonine requirement for 25–50 kg pigs fed a mixture of soluble and insoluble dietary fibre

A study was conducted to estimate the threonine (Thr) requirement of pigs fed high-fibre diets. Average daily gain (ADG) and gain to feed (G:F) were linearly and quadratically increased (P < 0.01) with increasing dietary Thr. Linear and quadratic breakpoint models estimated 0.76% and 0.80% standa...

Zusammenfassung:A study was conducted to estimate the threonine (Thr) requirement of pigs fed high-fibre diets. Average daily gain (ADG) and gain to feed (G:F) were linearly and quadratically increased (P < 0.01) with increasing dietary Thr. Linear and quadratic breakpoint models estimated 0.76% and 0.80% standard ileal digestible Thr to maximize ADG and 0.76% and 0.81% to maximize G:F, respectively.
