Evaluation Of Nutrients In The Potential Favorite Bamboo Shoots And Apparent Digestibility Of Nutirent Components In Bamboo Shoots Of Phyllostachys Vivax McClure On The Giant Panda

The giant panda (Ailuropoda melanoleuca) is a kind of rare and endangered species that is endemic toChina. Therefore, giant pandas have been receiving the high concern of the international community allthe time. Because of scarce number, ex-situ conservation of giant pandas has also been actively carriedout at home and abroad, except in-situ protection, to prevent the adverse natural environment in thedistribution region to affect its survival. The choice of different species of bamboos, evaluation ofnutrient components, and apparent digestibility of nutrient components in favorite bamboo are mainscientific basis to protect giant pandas. We took researches in Anji Bamboo Garden, of Anji County,Zhejiang Province. We adopted the cafeteria measurement and total feces collection method to study thechoice of different species of bamboos, evaluation of nutrient components, intake characteristics offavorite bamboo, and apparent digestibility of nutrient components of favorite bamboo. The main resultsare showed as follows:1. We used the cafeteria measurement to study the choice of different species of bamboo shoots, suchas Phyllostachys. vivax McClure, Phyllostachys bambussoides cv.tanakae, Phyllostachysbambusoides, and Pseudosasa amabilis McClure Keng f. We found the bamboo shoots of Ph. vivaxMcClure, Ph. bambussoides cv.tanakae, Ph. Bambusoides was preferred by trial giant pandas, whilethe bamboo shoots of Pse. amabilis McClure Keng f. wasn’t.2. The nutrient components and the mineral elements of bamboo shoots were measured and compared.The results indicated that components of neutral detergent fiber (NDF), acid detergent fiber (ADF),hemicellulose, cellulose, crude protein and P in the bamboo shoot of Pse. amabilis McClure Keng f.were significantly higher than those in bamboo shoots of Ph. vivax McClure, Ph. bambussoidescv.tanakae, Ph. Bambusoides (p＜0.01), while components of ether extract, K, Ca, Na, Mg, Cu, Fe,Zn and Mn were nearly equal.3. The study of intake characteristics of Ph. vivax McClure indicated the diameter of remnant stakes ofthe basal and the top of bamboo shoots were23.10～63.32mm and8.30～61.02mm while heightof remnant stakes of the basal and the top of bamboo shoots2.5～35.3cm and1.5～37.8cm. Thedifferent range of the diameter and height of the basal and the top of bamboo shoots was in eachgiant panda.4. The average apparent digestibility of crude protein and ether extract was86.36±1.70％and77.91±2.89％. The average apparent digestibility of NDF, ADF and hemicellulose was8.52±2.74％,4.79±1.44％and11.78±6.35％. The average apparent digestibility of minerals such as P, K, Ca,Mg, Cu, Zn and Mn was70.74±7.08％,37.17±7.29％,66.85±7.35％,44.39±4.43％,38.68±12.28％,45.38±7.62％,33.80±10.27％.
