摘　　要：为了制订《毕节高寒山区猪饲养标准》,丰富动物营养学内容,同时为高寒山区优质猪资源的开发利用和产业化发展提供科学依据,选择8周龄,体重（19.49±1.94）kg的毕节内二元（可乐×大约克）去势公猪19头,进行生长试验、消化试验和比较屠宰试验。结果表明,20~110kg体重段消化能（DE）转化为代谢能（ME）的效率为95.27%,维持的ME需要量为468kJ/W0.75,20~60kg、60~110kg体重段每增重1kg的ME需要分别为19.61MJ、30.69MJ,可乐×大约克生长肥育猪总能量需要模型：20~60kg体重段ME/（MJ/d）=0.468W0.75＋19.61ADG,60~110kg体重段ME/（MJ/d）=0.468W0.75＋30.69ADG。19 castrated Kele×Yorkshire hybrid pigs with eight weeks old and 19.49±1.94 kg body weight were used in growth,digestion and comparative slaughter experiments to provide the scientific base for formulating Feeding Standard of Swine in Bijie Cold Mountainous Area,exploitation and industrialization development of quality swine resources.The results showed that the conversion efficiency from digestion energy to metabolism energy reached 95.27% and the metabolism energy for maintenance was 468 kJ/W0.75 when the body weight of tested pigs was from 20 kg to 110 kg,and the metabolism energy for increasing 1 kg was 19.61 MJ and 30.69 MJ when the body weight of tested pigs was at 20~60 kg body weight stage and 60~110 kg body weight stage respectively.The total energy requirement for Kele×Yorkshire hybrid pigs at 20~60 kg body weight stage and 60~110 kg body weight stage is 0.468W0.75＋19.61 ADG and 0.468 W0.75＋30.69 ADG separately.
