【摘要】：本試驗旨在通過飼養(yǎng)試驗和消化試驗來評定紅花粕和水飛薊粕在生長獺兔上的營養(yǎng)價值。選取18只60日齡左右、平均體重(1.73±0.21)kg、健康狀況良好的白色獺兔,隨機分為3個組,每組6個重復(fù),每個重復(fù)1只兔。各組分別飼喂基礎(chǔ)飼糧、紅花粕飼糧(85%基礎(chǔ)飼糧+15%紅花粕)和水飛薊粕飼糧(85%基礎(chǔ)飼糧+15%水飛薊粕)。預(yù)試期和正試期各5 d。采用化學(xué)分析法測定紅花粕和水飛薊粕的總能(GE)及各營養(yǎng)物質(zhì)含量,采用全收糞法測定生長獺兔對各營養(yǎng)物質(zhì)的表觀消化率。結(jié)果表明:紅花粕和水飛薊粕中的GE、干物質(zhì)(DM)、粗蛋白質(zhì)(CP)、粗纖維(CF)、中性洗滌纖維(NDF)、酸性洗滌纖維(ADF)、酸性洗滌木質(zhì)素(ADL)、粗脂肪(EE)、粗灰分(Ash)、鈣(Ca)、磷(P)以及無氮浸出物(NFE)的含量分別為: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%與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%。生長獺兔對紅花粕和水飛薊粕中GE、DM、CP、CF、NDF、ADF、EE、Ash、Ca、P和NFE的表觀消化率分別為62.60%、61.72%、62.39%、15.68%、26.30%、14.75%、80.69%、38.35%、59.35%、31.98%、79.61%與63.13%、61.94%、68.01%、15.74%、27.64%、14.98%、79.90%、38.20%、60.44%、32.99%、79.81%。由此可見,生長獺兔對紅花粕和水飛薊粕中的不同營養(yǎng)成分的表觀消化率存在一定差異,結(jié)合2種原料各營養(yǎng)物質(zhì)含量總體分析,2種原料均可作為獺兔的蛋白質(zhì)飼料資源應(yīng)用,并且對生長獺兔的營養(yǎng)價值相近。
[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 鹵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厰瀵圭孩鑺辯矔鍜屾按椋炶摕綺曚腑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，
