Paddy and wheat generate multi-million tons of straw as residue. These two straws although similar in their nutrient content are quite different in microstructure and non- nutritive chemical composition. Paddy and wheat are both important cereal crops of Jammu and Kashmir. The scarcity of green fodder, pasture and quality hay has increased the onus over cereal crop residues, as their feeding to livestock offers no direct competition with human resources and requirements. Present study scrutinized the chemical composition and in vitro dry matter degrability (IVDMD) of these straws as a combination. The Percent OM, CF, NFE, NDF, ADF, calcium and phosphorus content were highest in W100P0 and lowest in W0P100, with progressively decline with the increasing concentration of paddy straw in the straw mixtures. Inverse trend was observed with respect to the CP, ether extract, total ash and acid insoluble ash content. The IVDMD declined progressively with an increase in percentage of paddy straw. The point of inflection, where this decline became significant at W50P50 combination. As paddy straw is a less preferred feedstuff as compared to wheat straw and is available at a significantly lower cost in most of the North-West parts of India, it was meaningful to select the maximum level of paddy straw in the combination (W60P40), that doesn’t affect the degradability significantly, therefore, the straw combination of W60P40 was determined suitable for small ruminant feeding.
