【摘要】：本试验旨在通过饲养试验和消化试验来评定红花粕和水飞蓟粕在生长獭兔上的营养价值。选取18只60日龄左右、平均体重(1.73±0.21)kg、健康状况良好的白色獭兔,随机分为3个组,每组6个重复,每个重复1只兔。各组分别饲喂基础饲粮、红花粕饲粮(85%基础饲粮+15%红花粕)和水飞蓟粕饲粮(85%基础饲粮+15%水飞蓟粕)。预试期和正试期各5 d。采用化学分析法测定红花粕和水飞蓟粕的总能(GE)及各营养物质含量,采用全收粪法测定生长獭兔对各营养物质的表观消化率。结果表明:红花粕和水飞蓟粕中的GE、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)以及无氮浸出物(NFE)的含量分别为:18.81 MJ/kg、93.76%、23.94%、14.95%、19.92%、11.99%、2.19%、1.64%、4.93%、0.37%、0.57%、49.32%与17.12 MJ/kg、91.94%、23.62%、16.21%、38.57%、22.73%、4.04%、2.07%、5.31%、0.29%、0.68%、42.09%。生长獭兔对红花粕和水飞蓟粕中GE、DM、CP、CF、NDF、ADF、EE、Ash、Ca、P和NFE的表观消化率分别为62.60%、61.72%、62.39%、15.68%、26.30%、14.75%、80.69%、38.35%、59.35%、31.98%、79.61%与63.13%、61.94%、68.01%、15.74%、27.64%、14.98%、79.90%、38.20%、60.44%、32.99%、79.81%。由此可见,生长獭兔对红花粕和水飞蓟粕中的不同营养成分的表观消化率存在一定差异,结合2种原料各营养物质含量总体分析,2种原料均可作为獭兔的蛋白质饲料资源应用,并且对生长獭兔的营养价值相近。
[Abstract]:The purpose of this study was to evaluate the nutritional value of safflower meal and silythistle meal in growing Rex rabbits by feeding and digesting experiments. Eighteen white Rex rabbits with average body weight of (1. 73 卤0. 21) kg, were randomly divided into 3 groups, 6 replicates in each group and 1 rabbit in each group. Each group was fed with basic diet, safflower meal diet (85% basic diet) and silythistle meal diet (85% basal diet 15% silychoke meal). The pretest period and the positive test period were 5 days respectively. The total energy (GE) and nutrient content of safflower meal and silythistle meal were determined by chemical analysis, and the apparent digestibility of nutrients of growing Rex rabbits was measured by the method of total fecal collection. The results showed that GE, dry matter (DM), crude protein (CP), crude fiber (CF), neutral detergent fiber (ADF), acid detergent lignin (ADL), crude fat (EE), coarse ash (Ash), (Ca), P (P) and nitrogen-free extract were obtained from safflower meal and silychoke meal. The contents of (NFE) were: 1: 18.81 MJ/kg,93.76%,23.94%,14.95%,19.92%,11.99%,2.19%,1.64%,4.93%,0.37%,0.57%,49.32% and 17.12 MJ/kg,91.94%,23.62%,16.21%,38.57%,22.73%,4.04%,2.07%,5.31%,0.29%,0.68%,42.09%., respectively. 鐢熼暱鐛厰瀵圭孩鑺辩矔鍜屾按椋炶摕绮曚腑GE,DM,CP,CF,NDF,ADF,EE,Ash,Ca,P鍜孨FE鐨勮〃瑙傛秷鍖栫巼鍒嗗埆涓，
