Abstract:

In order to effectively utilize the forage wild plant resources, expand the application of multi-index comprehensive evaluation methods in evaluating nutritive value of some plant leaves for forest musk deer, the contents of five proximate nutrients including crude protein, crude fiber, crude fat, nitrogen-free extract and crude ash of forage wild plant leaves were taken as the evaluation indexes, the nutritive value of different plant leaves was evaluated based on multi-index evaluation models such as Z-score, principal component method, Topsis method and entropy coefficient, and the four evaluation results were comprehensively evaluated for the second time. The results showed that there were some similarities among the four evaluation methods, such as the nutritive value of Cerasus serrula was the highest, some differences in the forage quality of some plants, and great differences in the evaluation results of individual plants. The second time comprehensive evaluation results were ranked as Cerasus serrula>Clematis gracilifolia>Chenopodium album and Betula platyphylla>Cornus macrophylla >Sorbaria arborea>Clematis potaninii>Aralia chinensis>Betula albo-sinensis>Clematis gracilifolia>Clematoclethra actinidioides>Vicia cracca>Salix cupularis>Cerasus clarofolia>Salix wallichiana>Hippophae rhamnoides>Sorbus hupehensis>Elaeagnus lanceolata and Berchemia polyphylla>Acer laxiflorum>Berberis dasystachya. The results could provide some ideas and methods for exploring the comprehensive nutritive value evaluation of the forage plant leaves for forest musk deer, and building a technical system related to the scientific and stable development of forest musk deer populations.

Key words: forest musk deer, forage plant leaves, proximate nutrient, nutritive value, multi-index comprehensive evaluation
