NUTRITIONAL VALUE OF GREEN MASS OF SWEET SORGHUM, SORGHUM-SUDANGRASS HYBRID AND SUDAN GRASS IN THE SOURTH EASTERN PART OF BELARUS

Abstract

The paper presents the data on nutritional value of green fodder of sweet sorghum, sorghum-sudangrass hybrid and sudan grass grown on sod-podzolic sandyloam soils with the average content of potassium mobile forms, high content of phosphorus mobile forms, insufficient content of humus and a medium acid reaction of soil. The content of fibre in green mass at the heading stage, soluble carbohydrates, crude protein, metabolic energy and feed units is shown. The values of sugar-protein ratios and the content of digestible protein in a feed unit of sorghum crops are established. The variability of the indicators of green fodder nutritional value in terms of the years of research is identified. A correlation is established between the hydrothermal coefficient and the indicators of nutritional value of green mass of sorghum crops.
