A research-and-economic experiment was carried out with a total of 8,621 geese of local breeds of 3.964 kg average body mass, fattened forcedly with steamed grain maize in the course of 20-30 days. The dynamic of a number of qualities was followed up with special emphasis on the live weight from the beginning to the end of the fattening period, the weight gain, the mass and quality of liver, and the intake of feed per kg of gain and per kg of liver mass. Determined was also the nutritive value of proteins contained in the liver as judged by the index of the amino acid ratio (tryptophan to hydroxyproline). It was found that local geese could be characterized by good fattening capacity, yielding high-quality liver of excellent organoleptic indices and high nutritive value at a comparatively low intake of feed.
进行了一项研究与经济实验,共选用8621只本地品种鹅,平均体重3.964千克,在20至30天内用蒸制的谷物玉米强制育肥。跟踪了多项品质的动态变化,特别关注育肥期开始到结束时的活重、增重、肝脏的重量和品质,以及每千克增重和每千克肝脏重量的饲料摄入量。还根据氨基酸比例指数(色氨酸与羟脯氨酸之比)判断了肝脏中所含蛋白质的营养价值。结果发现,本地鹅育肥能力良好,在饲料摄入量相对较低的情况下,能产出感官指标优异、营养价值高的优质肝脏。
