【摘要】：本研究旨在通过消化试验比较固态发酵菜籽粕(SFRSM)与菜籽粕(RSM)在生长肉兔上的营养价值,为家兔饲料原料数据库提供基础数据。在测定SFRSM和RSM化学组成的基础上,将36只42日龄、遗传背景相同的健康法国伊拉商品兔按体重相近原则随机分为3组(每组12只),饲养于粪尿可分开的代谢笼中,每笼1只,分别饲喂1种基础饲粮和2种试验饲粮(85%基础饲粮+15%SFRSM或RSM),进行体内消化试验。试验期11 d(预试期7 d,收集期4 d)。结果显示:1)与RSM相比,SFRSM的粗纤维(CF)、无氮浸出物(NFE)、酸性洗涤纤维(ADF)和异硫氰酸酯(ITC)含量极显著降低(P0.01),其他常规营养成分[除中性洗涤纤维(NDF)外]和小肽含量显著或极显著升高(P0.05或P0.01);各氨基酸含量不同程度提高,其中精氨酸(Arg)、天冬氨酸(Asp)、谷氨酸(Glu)、组氨酸(His)、异亮氨酸(Ile)、苯丙氨酸(Phe)、脯氨酸(Pro)和丝氨酸(Ser)含量达极显著水平(P0.01)。2)与RSM相比,SFRSM的消化能(DE)值(14.97 MJ/kg DM)提高了34.3%(P0.01);总能(GE)、粗蛋白质(CP)、ADF、NDF、钙(Ca)和总磷(TP)全肠表观消化率也有所提高(P0.05);各氨基酸全肠表观消化率不同程度提高,其中Asp、半胱氨酸(Cys)、甘氨酸(Gly)、Ile、酪氨酸(Tyr)和缬氨酸(Val)全肠表观消化率达显著或极显著水平(P0.05或P0.01)。总体而言,SFRSM对生长肉兔的营养价值高于RSM。
[Abstract]:The aim of this study was to compare the nutritional value of solid-state fermented rapeseed meal (SFRSM) and rapeseed meal (RSM) in growing meat rabbits through digestion experiments, and to provide basic data for the feed raw material database of rabbits.Based on the determination of chemical composition of SFRSM and RSM, 36 healthy French Eira rabbits of the same genetic background and 42 days of age were randomly divided into 3 groups according to the principle of similar body weight.One basic diet and two experimental diets were fed with 85% 15%SFRSM or RSM respectively.The trial period was 11 days (7 days for pretest and 4 days for collection).The results showed that compared with RSM, the contents of crude fiber, nitrogen-free extract, acid detergent fiber (ADF) and isothiocyanate (Isothiocyanate) of RSM were significantly lower than those of RSM, and the contents of other conventional nutrients (except neutral detergent fiber) and small peptides were significantly decreased or decreased significantly (P < 0.05), and the results showed that: (1) compared with RSM, the contents of nitrogen free extract (NFE), acid detergent fiber (ADF) and isothiocyanate (ITC1) were significantly lower than those of RSM.The content of each amino acid was increased in different degree.The apparent digestibility of total intestinal digestibility of CPF (ADFN NDF) and TP (TP) was also increased, and the apparent digestibility of all amino acids was increased in different degree.The apparent digestibility of Asp, cysteine, glycine Glycine Ile, tyrosine Tyr and Valine were significant or extremely significant (P0.05 or P0.01).In general, the nutritional value of SFRSM in growing rabbits was higher than that in RSM.
