填喂朗德鹅血液营养价值探析
Nutritious value analysis of Landes goose blood produced by force-feeding
-
摘要: 为了开发利用鹅肥肝生产的副产物——填喂后朗德鹅的血液资源,对其多种营养成分进行测定,并与未填喂朗德鹅血的相应成分进行对照分析,结果显示,填喂鹅血较未填喂鹅血水分含量降低5.97%,粗蛋白质、粗脂肪、灰分含量含量增长显著(p<0.05),分别是未填喂鹅血的1.37、1.57、1.42倍。血液生化结果表明,血浆中总蛋白含量是未填喂鹅血的2.09倍,球蛋白含量占血清总蛋白含量的比例增长1.4%,白蛋白则同比下降;同时,甘油三酯(TG)、胆固醇(TC)、高密度脂蛋白(HDL)含量增加显著(p<0.05),而低密度脂蛋白(LDL)的含量下降,但并不显著(p>0.05)。填喂的朗德鹅在矿质元素总量增加33.25%,常量元素磷和铁含量增长显著;微量元素中多种元素含量增加,其中铝含量最为显著(p>0.05),而铜、锰元素的含量下降;填喂鹅血维生素A含量是未填喂的2.39倍,超氧化物歧化酶(SOD)的活性和血红素含量较未填喂鹅血均有所提升。Abstract: To explore the nutritious value indexes of Landes goose blood after force-feeding. Main nutritional components were analyzed and compared with same ingredients in Landes Goose, which were raised in natural way. Results showed that the moisture level was decreased 5.97%, but the protein, fat and ash element in force-feeding Landes' blood were improved as 1.38, 1.57 and 1.42 times as the goose in natural diet type, respectively. the further biochemical determinations revealed that the total protein contents in plasma were 2.09times and the globin increased 1.4% of total serum protein, while the serum albumin comparably deceased.The TG, TC, and HDL-C rose sharply, but there was no obvious decreased in the content of LDL-C. The amount of minerals increased 33.25%. And Fe and P had remarkable sales growth but the content of Cu and Mn has declined. The content of vitamin A was up 2.39 times. The activity of SOD and the content of blood heme were both improved after force-feeding.
