IMPROVEMENT OF PRODUCTION TECHNOLOGY OF COMBINED FEED FOR QUAILS AGE 6 WEEKS AND OLDER

Abstract

Grass flour: artificially dried and ground into pieces up to 3 mm feed from grass plants. Artificially dried green feed is prepared from young legume plants, cereals, as well as legume-cereal grass mixtures and is used for feeding animals in pure form or as part of feed mixtures. The modern technology for preparing grass flour includes the sequence of the following processes: mowing grass, drying to 35-40 % moisture, selection of rolls with simultaneous grinding of green mass into particles of 10-30 mm in size, transportation, feeding by conveyor into the dryer drum, drying with a stream of hot air, grinding of the dried mass, cooling, storage in bulk or in granules, taring. In feeding quails, grass flour is used as a protein feed, as well as a source of coloring substances that affect the intensity of the yolk color, give the carcass a yellow color, which is popular with consumers. Grass flour from cereal grasses, clover, alfalfa, in an amount of up to 10% by weight of dry matter, can be added to the composition of compound feeds for quails, starting from 5 weeks of age. According to the results of the analysis of the technological process of producing compound feed for adult quails, it was improved by including grass flour in the feed mixture in the amount of 5% by weight or 50 kg per 1 ton of produced feed. The components in the feed mixture are distributed in the following ratio: wheat grits – 28 %, barley grits (without films) - 10, corn grits - 20, high-protein soybean cake - 25, grass flour - 5, protein and vitamin supplement for adult quails - 5, limestone flour - 5 and sunflower oil 2 %. In terms of nutritional value and physical form, the recommended feed mixture corresponds to the age group and nature of this species of animals, is characterized by high conversion into egg productivity of quails. In order to increase nutritional value and ensure an intense, uniform color of egg yolk, it is proposed to use grass flour in the composition of compound feeds for quails, which meets the requirements of the state standard for artificially dried grass feeds.
