Abstract
The full realization of the genetic potential of the bird is possible when the environmental conditions are maximally favorable for its manifestation. In this regard, when creating and using highly productive poultry, it is important to improve the technology of its cultivation and maintenance in parallel with the improvement of feeding conditions. The article presents the results of the analysis of the chemical composition and nutritional value of the feed, on the basis of which the recipe for the preparation of feed for ducks of different sex and age groups was compiled. The analysis of the results showed that the exchangeable energy content ranged from 6.1 to 12.0 MJ, crude protein from 205.0 to 438.0 g. Also, the highest content of amino acids was observed in meat meal and fodder yeast (27.9 - 34.4 / 10.3 - 12.9). In the course of the first two weeks of growing young ducklings, starting feeding rations were used. The feeding of young ducklings met the standards, and in days 1-7, "Start" compound feed was used, and in the following 7 days (7 - 14 days) - "Rost" compound feed. In the first period of cultivation (1-2 weeks), compound feed for birds (poultry) contained 20.20 - 21.90% protein and 13.99 - 14.27 MJ of exchangeable energy. In the second period of cultivation, the developed recipe feed contains 1,274 to 1,356 MJ of exchangeable energy and 17.2 to 17.6% crude protein. The results of this study are relevant and will be used to meet the demand of consumers in domestic selection of waterfowl adapted to the natural and climatic conditions of the region.
