Abstract

Abstract:

This research aims to clarify the contents and comprehensive ranks of the saccharide, protein and lipid nutrients of straw for livestock and poultry forage commonly used in Wenshan Prefecture of Yunnan Province, and to provide a basis for the nutrient-evaluation and configuration of the forage straw. The straw of Amomum tsaoko, Canna edulis ‘Xichou Bajiaoyu’, Capsicum annuum ‘WenJin No. 1’, Capsicum annuum ‘WenZiJiao No. 3’, Capsicum frutescens, Pairs polyphylla var. yunnanensis, Pennisetum purpureum and Zea mays ‘Wenqingzhu No. 2’ frequently used by livestock and poultry farmers in Wenshan in recent years was taken as the test material. The contents of the soluble sugars, total starches and soluble proteins of the straw were determined with spectrophotometry. The crude protein and crude fat contents were detected by using Kjeldahl nitrogen and Soxhlet extraction methods, and the comprehensive ranks of the saccharide, protein and lipid nutrients of the straw were evaluated with membership function. The results showed that the contents of soluble sugars and soluble proteins of P. polyphylla var. yunnanensis were the highest, reaching 163.603± 0.218 mg/g (DW) and 16.637±0.038 mg/g (DW), respectively. The contents of total starches and crude fats of ‘Wenqingzhu No. 2’ were the highest, reaching 283.008±2.507 mg/g (DW) and (3.598±0.055)%, respectively. The crude protein content of ‘Wenzijiao No. 3’ was the highest, which was about (11.864±0.202)%. Moreover, the difference of contents of soluble sugars, total starches, soluble proteins, crude proteins and crude fats among different kinds of straw all reached extremely significant levels, and the comprehensive ranks of the saccharide, protein and lipid nutrients of the eight kinds of straw were as follows: P. polyphylla var. yunnanensis>‘Wenqingzhu No. 2’>C. frutescens>‘WenZiJiao No. 3’>‘Xichou Bajiaoyu’>P. purpureum>‘WenJin No. 1’>A. tsaoko.

Key words: Wenshan Prefecture of Yunnan Province, forage straw, saccharide,protein and lipid nutrients, content and comprehensive rank, membership function
