摘要
为了探索籽粒苋对鹅的营养价值以及不同方法不同鹅品种对其真代谢能、常规养分利用效果与差异,分别选取健康成年五龙鹅(小型)和青农灰鹅(大型)公鹅各24只,各设4个处理组,每个处理组6只,试验鹅单笼饲养,每天强饲80 g,试验采用全收粪法。试验结果表明,籽粒苋对鹅是一种较为理想的粗纤维饲料;对籽粒苋进行营养价值评定时,采用强饲并添加维生素和微量元素的方法最好;两品种之间对籽粒苋的真代谢能及常规养分的利用率具有一定的差异。
The aim of the trial was to explore the nutritional value of amaranth meal and the differences of different methods and breeds to determine the true metabolic energy and the conventional nutrient-efficiency of it.24 healthy adult Wulong（mini-type） and Qingnong gray（large-scale） male geese were selected.The geese were divided into four treatment groups,with 6 geese in each group.Every goose was forced to feed 80 g per day.This trial adopted the method of total feces collection.Therefore amaranth meal was an ideal crude fiber feed for goose.It was better to be forced to feed single feedstuff with microelement and vitamin when evaluating the value of amaranth meal.There were some differences in the utilization of nutrition between the two breeds of geese.
