Extruded Castor-seed Meal for Feed

Force feed trials were conducted to estimate the metabolism energy and true digestibility of amino acids of extruded castor seed meal(ECM) for chick. And then, two performance trials were conducted to estimate the feed value of ECM for broiler chicken and growing pig. The results were that the chick metabolism energy of ECM was 9.29 MJ/kg,true digestibilities of amino acids were Asp 86.7%,Thr 77.3%,Ser 81.1%,Glu 90.0%,Gly 54.2%,Ala 78.5%,Cys 82.9%,Val 83.2%, Met 80.2%,Ile 83.2%,Leu 81.3%,Tyr 79.6%,Phe 84.4%,Lys 74.3%,His 90.5%,Arg 92.3%.There was no difference between treatment 1(3%,6%,9% ECM supplement to starter, grower, finisher diet) and the control in the broiler performance trial. In first phase of growing pig trial, there was no difference between treatment 1(5% ECM supplement) and the control, but there was different significantly between treatment 2(8% ECM supplement) and the control. In second phase of the trial, there was no difference among the treatments. The results suggested extruded castor seed meal has high feeding value.
