In 5 trials using a total of 5,7000 geese (Deutsche Legegans maleXWhite Italian Goose female) of which 482 were slaughtered and subsequently dressed, the influence of varying net energy and crude protein levels in the ration on fattening and carcass performance were studied. Increased crude protein contents were found to improve the meat yield. High-energy feeding likewise caused gains to go up, the extra gain almost exclusively consisting in adipose tissue (particularly skin, and intestinal and abdominal fat). In addition, high energy intakes induced earlier juvenile moulting, this effect making the 56-day old carcasses rather bristly. Therefore, it seems more convenient to fatten geese on low-energy rations (500 energetic feed equivalents/poultry [EFp] per kg) up to the age of 63 days because the meat yield (especially of breast meat) is likely to improve considerably when slaughter takes place at a later date. Goose fattening rations should stick to the following parameters (per kg): 500--550 EFp, 160--180 g crude protein, 8 g lysine, 6.5 g thio-amino acids.
在5项试验中，共使用了57000只鹅（德国白鹅公×意大利白鹅母），其中482只被屠宰并进行了屠体处理，研究了日粮中不同净能和粗蛋白水平对育肥和屠体性能的影响。结果发现，粗蛋白含量增加可提高肉产量。高能饲喂同样使增重增加，额外的增重几乎完全是脂肪组织（特别是皮肤、肠道和腹部脂肪）。此外，高能量摄入导致幼鹅换羽提前，这种影响使63日龄的屠体相当粗糙。因此，在63日龄前用低能量日粮（每千克500能量饲料单位/家禽[EFp]）育肥鹅似乎更方便，因为如果在稍后的日期屠宰，肉产量（尤其是胸肉）可能会显著提高。鹅育肥日粮应符合以下参数（每千克）：500 - 550 EFp、160 - 180克粗蛋白、8克赖氨酸、6.5克硫氨基酸。
