Study of the biological characteristics of the disintegration of dry matter and yellow melilot protein in the rumen of cows

With the intensification of animal husbandry more attention should be paid to the proper balanced animals feeding. High productivity of animals and effective use of feed can be ensured through the use of scientifically based feeding systems. In addition, the edibility of feed is mainly influenced by their quantitative and qualitative indicators: the appetite, feeding zone and animals’ rest areas equipment, or a technological feeding system. The objective of this work was to study the methodological approaches to control the above processes in the rumen of cows on the example of disintegration of dry matter and protein of yellow melilot (Melilotus officinalis). At the same time the question of preservatives and the melilot growing season influence on the process of utilizing the protein of the feed was being resolved. According to the results of the studies it proved possible to use fresh meliot for livestock feeding which practically meet the animals’ need for digestible protein. The influence of the growing season or the mowing time on the disintegration of crude protein and dry matter of silos and canned press residues is low (r=0.24 and r=0.11, respectively; P> 0.95), except for the full blossom phase, when the disintegration decreases significantly. Thus, it is possible to recommend mowing the meliot green mass and carrying out ensiling from the beginning of budding to the beginning of full blossom in order to obtain high quality forage. It is also recommended to use benzoic acid 3 kg / t of mass as a preservative for silage from melilot of the late vegetation phase in the technology of its harvesting.
