【摘要】 目的探讨树鼩乳汁的基本成份,并和其它乳制品成份进行了比较分析。方法选取10只分娩后(1~21)d期间的哺乳期母树鼩,用人工被动母乳喂养方法让仔树鼩自由吮吸母乳,立即采用无菌操作的方法用注射器直接采取仔树鼩胃内的乳汁,1次/2 d,连续3~5次,每只母树鼩采取18 mL乳汁,按照国家标准的方法进行成分检测。结果树鼩乳汁总固形物为43.63%、脂肪为26.01%、蛋白质为10.41%、乳糖为0.45%、灰分为0.99%。树鼩乳的总固形物、灰分、蛋白质、脂肪、乳糖含量分别为牛乳的3.36、1.24、2.74、6.67、0.09倍;树鼩乳的总固形物、灰分、蛋白质、脂肪、乳糖含量分别为婴幼儿配方乳的1.44、0.20、0.58、1.53、0.06倍;与牛乳及婴幼儿配方乳矿物质成分含量相比,树鼩乳的矿物质成分钙、磷、钾、钠、镁、铁、锌含量均大于牛乳,分别为1.83、2.73、1.25、1.93、1.28、1.48倍,而均小于婴幼儿配方乳,分别为0.66、0.85、0.34、0.26、0.85、0.24、0.49倍。结论树鼩乳的主要营养成分呈现高脂高蛋白低糖的类型,可为树鼩人工育幼和饲养工作提供依据。更多还原

【Abstract】 Objective To explore the basic ingredients of the tree shrew’s( Tupaia belangeri) milk and compare with the dairy ingredients of other milks. Methods We select ten seed tree shrews after delivery( 1 ~ 21) d with lactation mother tree shrews,and use artificial passive breastfeeding method let the young tree shrews suck breast milk,we took the milk from the young tree shrews in the stomach,directly using aseptic operation with a syringe immediately,once every two days,for consecutive three to five times,and a total of 18 mL milk was taken from each seed tree shrew. Then the milk was detected according to the national standard method for component testing. Results The total solid content of the tree shrew’s milk was 43. 63%,including 26. 01% of fat,10. 41% of protein,0. 45% of lactose and 0. 99% of ash content. Compared with cow’s milk,the tree shrew’s milk contained 3. 36 times of total solid contents,1. 24 times of ash,2. 74 times of protein,6. 67 times of fat,and 0. 09 times of lactose. Compare with baby formula milk,the tree shrew’s milk contained 1. 44 times of total solid contents,0. 20 times of ash,0. 58 times of protein,1. 53 times of fat,and 0. 06 times oflactose. The trace mineral composition of the tree shrew’s milk showed that the calcium,phosphorus,potassium,sodium,magnesium,and iron contents were 1. 83 times,2. 73 times,1. 25 times,1. 93 times,1. 28 times,and 1. 48 times higher than those in the cow’s milk,and were 0. 66 times,0. 85 times,0. 34 times,0. 26 times,0. 85 times,0. 24 times lower than those in baby formula milk. Conclusions The main nutrients of tree shrew’s milk is of high fat,high protein and low sugar,and it can provide a basis for tree shrews artificial brood and breeding work.更多还原
