【摘要】：本試驗旨在研究日糧中添加金針菇菌渣對山羊養(yǎng)分表觀消化率和血清生化指標的影響,并確定山羊飼糧中金針菇菌渣的最佳添加水平。選取28只年齡接近的健康波雜羊(波爾山羊×徐淮山羊),平均體重為(23.35±2.45)kg,隨機分為4組,每組7只。分別飼喂金針菇菌渣添加水平為0%(對照組,日糧A)、15%(日糧B)、25%(日糧C)、40%(日糧D)的試驗日糧,預(yù)飼期7d,試驗期45d。結(jié)果表明:(1)日糧中添加金針菇菌渣可有效提高山羊營養(yǎng)物質(zhì)消化率,日糧B、日糧C和日糧D的干物質(zhì)(DM)、有機物(OM)、粗蛋白(CP)、中性洗滌纖維(NDF)、酸性洗滌纖維(ADF)、鈣(Ca)、磷(P)以及能量的表觀消化率顯著高于日糧A(P0.05),其中,日糧B和日糧C的營養(yǎng)物質(zhì)消化率有高于日糧D的趨勢;(2)四組日糧的總蛋白(TP)、白蛋白(ALB)、谷丙轉(zhuǎn)氨酶(ALT)、谷草轉(zhuǎn)氨酶(AST)、堿性磷酸酶(ALP)和總膽紅素(TBIL)的含量無顯著影響(P0.05)。日糧C的葡萄糖(GLU)顯著高于日糧A、日糧B和日糧D(P0.05),日糧B日糧C和日糧D的尿素氮(BUN)差異不顯著(P0.05),但顯著高于日糧A(P0.05)。結(jié)果提示,在本研究背景下,在山羊飼料中添加金針菇菌渣可有效提高山羊營養(yǎng)物質(zhì)消化率,其中以15%和25%添加組效果較為明顯,并且對山羊血清生化指標無顯著影響,但提高了血液中尿素氮的含量。
[Abstract]:The purpose of this study was to study the effects of Flammulina velutipes residue on the apparent nutrient digestibility and serum biochemical indexes of goats. The optimum addition level of Flammulina velutipes in the diet of goats was determined. 28 healthy Boer goats (Boer goat 脳 Xuhuai goat) with an average body weight of 23.35 鹵2.45 kg were randomly divided into 4 groups. Seven rats in each group were fed with Flammulina velutipes (Flammulina velutipes) residue supplementation level was 0 (control group, diet Af15). The results showed that adding Flammulina velutipes residue into the diet could effectively increase the digestibility of nutrients in goats. The apparent digestibility of dry matter (DMN), organic substance (OMN), crude protein (CP), neutral detergent fiber (NDFN), acid detergent fiber (ADFN), calcium caproxide, phosphorus (P) and energy in diet B, C and D were significantly higher than those in diet Agna P0.05N, and the apparent digestibility of energy in diet B, C and D was significantly higher than that in diet A (P 0.05). The nutrient digestibility of diet B and C was higher than that of diet D.) there was no significant effect on the contents of total protein TPN, Albumin, alanine aminotransferase (alt), alanine aminotransferase (alt), alkaline phosphatase (ALP) and total bilirubin (TBIL) in the diet of four groups. The glucose GLU in diet C was significantly higher than that in diet A, the difference between dietary B and D was not significant (P 0.05), but it was significantly higher than that in diet A (0.05). The results suggested that there was no significant difference between dietary C and D (P 0.05), but significantly higher than that in diet A (0.05), the results suggested that the level of glucose in diet C was significantly higher than that in diet A (P 0.05). Under the background of this study, adding Flammulina velutipes residue into goat feed could effectively improve the digestibility of nutrients in goats. The effects of 15% and 25% supplementation groups were more obvious, and there was no significant effect on serum biochemical indexes of goats. However, the level of urea nitrogen in blood was increased.
