试验选择大白猪（加×美）二元杂种猪24头（仔猪3～4周龄断奶,保育到8周龄）,随机分为对照组、苜蓿Ⅰ组和苜蓿Ⅱ组,每组8头,分别饲喂基础日粮、基础日粮＋3%苜蓿、基础日粮＋6%苜蓿,试验期内在同一条件下进行饲养试验对其育肥性能、屠宰测定及肉质品质进行测定。试验结果表明：苜蓿Ⅰ组能够提高外二元猪育肥效果,苜蓿Ⅰ组和苜蓿Ⅱ组对背膘厚和皮厚也略有降低,添加3%和6%的苜蓿对其他屠宰性能及肉质品质影响不显著（P〉0.05）。由试验结果得出,在毕节高寒地区可以利用添加3%苜蓿比例的饲料对外二元杂交猪进行育肥。%In this study,24 binary hybrid pigs（ D × Y） about 8 weeks were chosen, and they were randomly allocated into three dietary treatments ： control group （basic diet）, Medicago sativa group Ⅰ （basic diet ＋ 3 % Medicago sativa）, Medicago sativa group Ⅱ （basic diet ＋ 3% Medicago sativa）, except the diet, the pigs were fed in the same condition. After 98 days, the Fattening and Slaughtered performances were measured. The results showed that the Medieago sativa group Ⅰ improved the fattening performances, Medicago sativa group I and Medicago sativa group Ⅱ reduced baekfat thickness and skin thickness a little, to added 3 % and 6 % Medicago sativa into the basic diet had no significant influence on the othcr fattening and slaughtered performances. So we concluded that to add 3% Medicago sativa into the basicdiet to fatten the binary hybrid pig in the alpine region of Bijie was feasible.
