DIGESTIBILITY OF NUTRIENTS OF ALFALFA DIFFERENT VARIETIES IN THE SEPARATE PHASES OF DEVELOPMENT
Posternak L.I., Candidate of Agricultural Sciences, Associate Professor
Vinnytsia National Agrarian University
The basis of the new system for assessing the nutritional value of feed and rations should consist in the idea that feed assessment can be objective only when taking into account the diverse characteristics of its nutritional properties, which are determined by the presence (quantity and quality) of all essential nutrients such as carbohydrates, proteins, fats, minerals and vitamins, as well as the energy available to animals in the diet. The nutrients coming with food in the digestive tract of animals are in the form of complex organic compounds, which cannot be directly absorbed into the blood and used for their own needs. The physiological process of splitting the organic compounds into such simple forms that can easily penetrate into the bloodstream and participate in the intermediate metabolism is called digestion. Not all chemical compounds in the feed are digested; some compounds are digested only partially. The nutrients digestibility of rations and individual feeds is expressed as a percentage of the amount. The difference between the amounts of consumed substances in the feed and of those excreted in the feces is called the nutrients digestibility of the feed. The digestibility is expressed as a relative number in percent, which is called the digestibility factor and shows the degree of digestion of a certain substance in the digestive tract. The degree of digestion is very changeable and depends on many factors. The level of digestion is very affected by the composition of the feed dose, the level of some nutrients in the diet, the size of the feed load, species, animals and other factors. The digestibility is also influenced by the animal’s individuality. According to O. Dmytrochenko and P. Pshenychyi, the influence of this factor depends on the temperament, growing conditions, as well as the structure and functions of the digestive system. After having conducted the research on digestion of alfalfa nutrients, it was found that the coefficients of alfalfa nutrients digestibility depend on both the phase of development and the variety. The analysis of the presented material showed that alfalfa grass of the Vinnychanka variety has higher nutritional value than those of Liubava and Regina. The content of feed units, gross and exchange energy in alfalfa of all varieties was higher in the phase of budding than in the flowering phase. The alfalfa nutrients of the first slope were digested better than those of the second one.
