Ihe fractional composition of fiber in the assessment of the quality of modern feed
According to the modern approaches to determine the quality of feed, standard feed analysis should include the neutral-detergent (NDF) and acid-detergent (ADF) fiber. The fractional composition of carbohydrates in samples of green mass in Timofeevka and oat, selected in the experimental field of the Primorskaya GSHA, is considered. The analysis was carried out by Cherkizovo Research and testing center LLC, Moscow on an automatic fiber analyzer ANKOM A2000. It was found that the sum of hemicelluloses and cellulose in the perennial culture of timofeevka is higher and amounted to 69 % against 62 % in the annual culture of oats. The assimilability of feed of Phleum pretense L. will be lower (ADF 29.6 % vs. 11 % for Avena sativa). Phleum pretense L. feed contains 75.1 % NDF, 6.6% less than oat feed. As for the content of lignin, the plant mass of Phleum pretense L. and Avena sativa does not differ significantly.
