摘要

摘要本研究旨在验证有机饲养条件下丹麦长×杜roc生长猪的苜蓿干叶(AL)和/或苜蓿青贮(AS)对生长性能和胴体性状的影响。饲喂全混料20头猪(A组和B组)，其中10头猪饲喂AL的比例高达20% (B组)。另外20头猪饲喂AS的比例高达30% (C组和D组)，其中10头猪饲喂AL的比例高达日粮的15% (D组)。A组和B组的生长性能和胴体性状基本一致。在全饲料中添加20% AL似乎是可行的。D组的生长性能和胴体性能均部分显著低于A组和B组。与A组相比，B组每头猪使用AL可节省27 kg蛋白质饲料。

Growth performance and carcass traits of growing pigs consuming different alfalfa (Medicago sativa) products in organic farming systems

ABSTRACT The aim of this study was to prove the effects of dried alfalfa leaves (AL) and/or alfalfa silage (AS) in growing pigs (Danish Landrace x Duroc) under an organic feeding regime on growth performance and carcass traits. Twenty pigs were fed complete feed mixtures (groups A and B) of which 10 received proportions of AL (up to 20%) (group B). Another 20 pigs received AS (up to 30%) (groups C and D) of which 10 received proportions of AL (up to 15% of the ration) (group D). Groups A and B achieved the same growth performance and carcass traits. The use of 20% AL in the complete feed seemed to be feasible. Group D showed partially significantly lower growth and carcass performances than groups A and B. The use of AL saved 27 kg of protein feed per pig in group B compared to group A.
