The purpose of the experiment was to study the main nutrient contents of straw and blighted husk roughage, and to provide theoretical basis for the efficient utilization of roughage. The results showed as follows: The order for feeding value of 8 kinds of roughage were soybean hull, peanut straw, wheat hull, rice straw, wheat straw, soybean straw, rice hull, peanut hull, and the feeding value were 159.43, 133.82, 122.57, 112.17, 100.25, 91.64, 56.02, 46.27, respectively. The feeding value, grading index and the contents of dry matter, ether extract, crude ash and crude protein of different roughages were significantly different (P<0.01). The moisture content and feeding value and grading index of peanut straw among straw of roughage were the highest, and the contents of crude ash and crude fat were lower; The moisture content and feeding value and grading index of soybean hull among hull of roughage were the highest, and the contents of crude ash and crude fat were lower. Therefore, soybean hull and peanut straw can be developed and utilized as roughage of high nutritional value. [ABSTRACT FROM AUTHOR]
