Estimation of L-threonine requirements for Longyan laying ducks

Estimation of L-threonine requirements for Longyan laying ducks

Objective A study was conducted to test six threonine (Thr) levels (0.39%, 0.44%, 0.49%, 0.54%, 0.59%, and 0.64%) to estimate the optimal dietary Thr requirements for Longyan laying ducks from 17 to 45 wk of age. Methods Nine hundred Longyan ducks aged 17 wk were assigned randomly to the six dietary...
