饲料系数又称增肉系数，指鱼对某种饲料在一定时间内吃食的总重量与鱼体在这段时间内增重量的比值。计算公式为：总投饲量／总增重量，也即：总投饲量／收获时的鱼的总重量减放养时鱼的总重量。饲料系数是考察饲料营养价值高低和养殖技术水平的主要指标，影响其主要因素有... The coefficient of feed, also known as meat gain coefficient, refers to the ratio of the total weight of fish fed on a certain feed within a certain period of time to the weight gain of the fish during this time. Calculated as: total feed / total weight gain, that is: the total amount of feed / fish at harvest time minus the total weight of fish when raising. Feed factor is to examine the nutritional value of feed and aquaculture technology level of the main indicators, affecting its main factors are ...
