Determining protein degradability of oil seed meals protein using in situ method

Feed evaluation provide essential informations to animal nutritionists for better feed formulation on the basis of physiological and economical view of point to improve animal performance. There are various feed evaluation method at present time and In situ technique (nylon bag or in sacco method) is commonly used in this way. In this study, ruminal degradability of dry matter, organic matter, crude protein and ADF was measured. Four different oil seed meals consist of canola meal, cotton seed meal, soybean meal and sunflower meal was studied using in situ method. Results of this experiment indicated that degradability (a+b) and effective degradation (EP) in soybean meal, canola meal and cotton seed meal produced in Behpak oil plant was (98.5, 98.7 and 56.8%) and (55.8, 62.0 and 48.3%) and for soybean meal, canola meal and sunflower meal produced in kesht-o-sanat oil plant was (81.7, 90.1 and 90.5%) and (47.1, 52.5 and 45.2%) respectively.
