Effects of Cordyceps Feed Additive on Production Performance and Egg Quality in Laying Ducks


  [Objective] To investigate effects of Cordyceps feed additive on growth performance,laying rate and egg quality in laying ducks.[Method] A total of 270 healthy laying ducks were randomly divided into three groups,90 ducks in each group.The ducks in the control group,group I and group II were fed common basal diet,basal diet containing 10 g/kg Cordyceps feed additive and basal diet containing 40 g/kg Cordyceps feed additive,respectively.The trial lasted for 28 d.During the whole trial,the ducks were weighed and their growth was observed at an interval of 7 d.The exterior quality and the nutritive indexes of duck eggs were determined.[Result] After experiments,the body weights of ducks in the group I and group II were increased and higher than that of the control group.In the group I and group II,the laying rate was increased by 1.07% and 2.15%,respectively;the egg weight was increased by 3.95% and 4.16%,respectively;and the feed to egg ratio was decreased by 2.54% and 4.23%,respectively.The egg shape and eggshell thickness were consistent between the control group and experimental groups.In the group I and group II,the protein content of the duck eggs was increased by 5.55% and 17.15%,respectively;the cholesterol content was decreased by 11.79% and 42.14%,respectively;the IgY level was increased by 13.20% and 27.97%,respectively;and the lecithin content was increased by 5.13% and 11.69%,respectively.[Conclusion] The Cordyceps feed additive can increase the body weight and laying rate of laying ducks and improve the quality of duck eggs.……
