The materials used were 13 lines of Sorghum</p><p>bicolor supplied by the International Center for Tropical</p><p>Agriculture (CIAT), and 2 lines of Sorghum almum. Yield</p><p>production, bromatologic composition and ruminal</p><p>degradability of these lines were measured. The following</p><p>results were obtained: CIAT 638 showed the highest dry</p><p>mater production but the lowest crude protein levels; the</p><p>materials CIAT 613 and CIAT 645 showed the highest</p><p>degradation rate, while the lines ATENAS, CIAT 897, CIAT</p><p>638 y UCR-EEAVM showed the highest crude protein levels</p><p>and good digestibility of the dry matter.</p> ER -
