Abstract

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.

有机耕作系统中不同苜蓿产品对生长猪生长性能和胴体性状的影响

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。
