摘要
为评定葵花籽粕和花生壳在生长兔上的营养价值,本试验选择18只110日龄平均体重(2.34±0.16)kg的白色獭兔,随机分为3组,每组6个重复。试验饲粮用套算法进行配制,葵花籽粕和花生壳的替代比例为20%;采用全收粪法进行消化试验,预试期和正试期各5 d。结果表明:1)葵花籽粕和花生壳中的总能(GE)以及干物质(DM)、粗蛋白质(CP)、粗纤维(CF)、中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)、酸性洗涤木质素(ADL)、粗脂肪(EE)、粗灰分(ash)、钙(Ca)、磷(P)和无氮浸出物(NFE)含量分别为20.07 MJ/kg、93.79%、28.72%、23.66%、38.48%、27.97%、8.08%、6.73%、5.47%、0.89%、0.88%、29.21%和17.34 M J/kg、93.11%、8.68%、50.91%、63.28%、55.33%、21.08%、1.66%、9.16%、0.53%、0.10%、22.69%;2)葵花籽粕和花生壳在生长兔中的表观消化能分别为(10.89±3.88)和(6.11±3.46)M J/kg DM,生长兔对葵花籽粕和花生壳中的GE、DM、CP、CF、NDF、ADF、EE、ash、Ca、P和NFE的消化率分别为50.87%、46.81%、82.37%、23.60%、29.09%、26.81%、87.89%、58.09%、72.56%、49.50%、80.79%和32.82%、28.89%、81.54%、23.20%、28.62%、26.20%、87.72%、58.16%、72.73%、49.39%和81.12%。由结果可知:生长兔对葵花籽粕和花生壳中CP、EE、Ca和NFE的消化率较高,对CF的消化率低,不能消化ADL。
The trial was carried out to evaluate the nutritive value of sunflower meal and peanut hull for growing rabbits.Eighteen growing rabbits at 110 days of age with an average weight of（2.34±0.16） kg were used in a completely randomized design,which consisted of 3 groups and 6 replicates in each group.A basal diet was formulated to meet requirements of growing rabbits and two other diets were formulated by substituting 20% of the basal diet with sunflower meal or peanut hull,respectively.Fecal apparent digestibility of major nutrients in sunflower meal and peanut hull for growing rabbits was measured.Both pre-trial and trial period was 5 days.It was observed that gross energy（GE）,dry matter（DM）,crude protein（CP）,crude fiber（CF）,neutral detergent fiber（NDF）,acid detergent fiber（ADF）,acid detergent lignin（ADL）,ether extract（EE）,ash,Ca,P and nitrogen free extract（NFE） contents of sunflower meal were 20.07 MJ/kg,93.79%,28.72%,23.66%,38.48%,27.97%,8.08%,6.73%,5.47%,0.89%,0.88% and 29.21%,and those above indexes of peanut hull were 17.34 MJ/kg,93.11%,8.68%,50.91%,63.28%,55.33%,21.08%,1.66%,9.16%,0.53%,0.10% and 22.69%.The apparent digestible energy of sunflower meal and peanut hull were（10.89±3.88） and（6.11±3.46） MJ/kg DM,respectively.Apparent digestibility of energy,DM,CP,CF,NDF,ADF,EE,ash,Ca,P and NFE in sunflower meal were 50.87%,46.81%,82.37%,23.60%,29.09%,26.81%,87.89%,58.09%,72.56%,49.50% and 80.79%,and those above indexes in peanut hull were 32.82%,28.89%,81.54%,23.20%,28.62%,26.20%,87.72%,58.16%,72.73%,49.39% and 81.12%,respectively.In conclusion,apparent digestibility of CP,EE,Ca and NFE in sunflower meal and peanut hull for growing rabbits were higher,while apparent digestibility of CF in sunflower meal and peanut hull for growing rabbits were lower,and the ADL was not able to be digested by growing rabbits.
