摘要 本试验用190只体重2.4kg左右的朗德鹅为试验动物,以稻壳粉为主要粗纤维源,根据公母各半的原则,试验前随机抽取10只进行屠宰试验,其余180只随机分成试验1组、试验2组、试验3组,每组60 只,每组三个重复,每个重复20只,进行4周的饲养试验。研究日粮在等能量等蛋白水平下,不同粗纤维水平 (4%、8%、12%)对朗德鹅生产性能、屠宰性能和血清部分生化指标的影响。结果表明:(1)日粮粗纤维含量为8%时,可以获得理想的生产性能,差异显著(P<0.05);(2)随着日粮粗纤维水平升高,除对尿酸(UA)、尿素(UR)、葡萄糖(GLU)、总蛋白(TP)没有产生显著影响(P>0.05)外,显著地影响(P<0.05)了血浆总胆固醇 (TC)、甘油三酯(TG)、低密度脂蛋白(LDL)、极低密度脂蛋白(VLDL)、载脂蛋白B(ApoB)、高密度脂蛋白 (HDL)、碱性磷酸酶(AKP)、淀粉酶(AL)、谷丙转氨酶(ALT)和谷草转氨酶(AST)的水平(P<0.05)。同时, 也显著地影响了屠宰性能指标(P<0.05);(3)从胴体品质看,高粗纤维日粮水平有较低的腹脂沉积,VLDL可能是朗德鹅脂肪合成的一个限制因素。 Abstract 190 Landes geese of weight about 2.4kg each were used to study the effects of diets containing different crude fiber levels ( 4%, 8%, 12% ) with equal energy and protein on bird growth performance, dressed performance and partial blood biochemical indexes. 10 gooses were killed for checking dressed performance before experiment, and other 180 birds were divided into three treatments by sex and fed for 4wks, three repeats per treatment and 20 birds per repeat. Rice hull meal was selected as the main fiber sources in the test diet. The results show that: (1) Diet containing crude fiber of 8% gives the top growth performance, differs significantly (p 〈0.05). (2) Further increase of dietary fiber exhibits significant effect on serum indexes including total cholesterol ( TC), triglyceride (TG), low density lipoprotein (LDL), very low density lipoprotein (VLDL), ApoB, high density lipoprotein (HDL), alkaline phosphatase (AKP), amylase (AL), glutamate- pyruvate transaminase (GPT) and glutamicoxalacetic transaminase (GOT) (p 〈 0.05 ), as well as on dressed performance (p ~ 0.05 ), but no significant effects on urea acid (UA), urea (UR), glucose (GLU), and total protein (TP) (p 〉0.05) . (3) High fiber level diet leads to a drawn poultry of lower adipose tissue. VLDL may be a limiting factor for lipid synthesis in the Landes goose.
