妊娠后期梅花鹿母鹿精料营养成分分析及营养物质表观消化率测定

Analysis on Nutrient Composition and Measurement for Apparent Digestive Rate of Nutrient Matter in Purified Diet for Female Deer of Cervus Nippon Temminck Denning during Late Stage Pregnancy

摘要:

本研究采用化学分析和部分粪便收集法，对大连森林动物园妊娠后期梅花鹿精料营养成分及主要营养物质的表观消化率进行测定。结果表明：大连其精料中干物质（DM）含量为95．71％，粗蛋白（CP）为22．88％，粗脂肪（EE）为5．37％，粗纤维（CF）为4.16%，无氮浸出物（NFE）为56．21％，粗灰分（Ash）为7．09％，Ca为1．57％，总能（GE）含量为17.74mJ／kg；母鹿日干物质摄入量为1．26kg，DM、CP、CF、Ca和GE表观消化率分别为74.26％，74.26％，82．74％，69．38％，79．41%和78．25%。精料中主要营养成分、干物质日摄入量及营养物质消化率均较高，能满足妊娠后期梅花鹿母鹿在动物园这种特殊环境下的营养需要。

Abstract:

In this study, measurement on nutrimental composition and apparent rate for nutrimental matter have been carried out to purified diet for Cervus nippon Temminck in Dalian forest zoo during late stage of pregnancy by use of chemical analysis and partial dung collection methods. The results show that purified diet from Dalian, there contain 95.71% of dry mass (DM), 22.88% of crude protein (CP), 5.37% of essential ester (EE), 4.16% of crude fiber(CF), 56.21% of non-nitrogen's extract (NFE), 7.09% of crude ash,1.57% of calcium and 17.74 mJ/kg of general energy (GE); dry mass intake by female deer per day is 1.26 kg, apparent digestive rates for DM,CP,CF,Ca and GE are 74.26%,74.26%,82.74%,69.38%,79.41% and 78.25% respectively. The main nutritional composition, daily intake of dry mass are all higher together with higher digestive rate of nutrimental mass, which can meet nutrimental requirement under special environment in the zoo for female deer of Cervus nippon Temminck during late stage of pregnancy.
