Abstract
The materials of the article present data on research on the chemical, mineral-vitamin composition and nutritional value of a new feed additive from citrus pomace. The article presents the results of research on the technological line of granulation of citrus waste, established the optimal composition for granulation of citrus feed additives: sunflower meal - 20%, molasses - 5% and 75% of citrus fruits.Their chemical composition was studied, the gross content of proteins, fats, assimilated carbohydrates, including simple sugars, was determined, and the efficiency of use in the diets of farm animals was determined. The positive influence of citrus waste granulation technology has been established, which allows to obtain high-quality granules. Chemical analysis of citrus granules showed that 100 g contains: protein - 6.15 g, fat - 0.99 g, carbohydrates - 21.8 g, of which simple sugars 14 g, the energy value of this feed additive - Kcal (kJ) - 120.7 (505.7).The possibility of preparation of feed additives in the form of granules is revealed, which allows to avoid selfsorting of components and overdose of microelements and to improve the consumption of feed ingredients. The ability to prepare feed additives in the form of granules avoids self-sorting of components and overdose of micronutrients and improve the consumption of feed ingredients. The results of zootechnical researches, structure and nutritional value of average daily rations with use of citrus pomace are resulted.It was found that the introduction into the diet of dairy cows feed additives from citrus pomace during stable lactation increases the average daily expectations by 1.8 kg or 15.5%, feed costs for milk production containing 4 fat were 0.97-0, 98 feed units. When using a feed additive from citrus pomace, the nutritional value of the diet is improved due to the ratio of sugar - protein (0.62: 1 vs. 0.8: 1.2).
Highlights
Domestic and world experience of increasing the production of livestock products and reducing their cost shows that in recent years an increase in animal productivity by 65% has been achieved by improving their feeding system and advanced housing technologies
It follows that the organization of rational full-fledged feeding of farm animals is one of the main conditions for further increase of their productivity [3, 5, 9]
Laboratory studies to study the chemical composition of citrus granules were conducted in the Research and Service Company "OTAVA" in 2019
Summary
Domestic and world experience of increasing the production of livestock products and reducing their cost shows that in recent years an increase in animal productivity by 65% has been achieved by improving their feeding system and advanced housing technologies. It follows that the organization of rational full-fledged feeding of farm animals is one of the main conditions for further increase of their productivity [3, 5, 9]. As the knowledge of the animal's need for nutrients increases, so does the concept of the level of a complete diet. It is established that the animal body needs the optimal amount of nutrients and biological substances [1]
