Abstract
As the development of the feed industry is characterized by the intensification of technological processes aimed primarily at improving sanitary quality, the methods of preliminary wet-heat preparation of mixed fodder, in particular, the application of expansion to the granulation process, has been presented in the article. The effect of heat treatment on the nutrient absorption of individual ingredients of compound feed has been the subject of many research. In general, the wet-heat treatment of compound feed can improve the digestibility of nutrients, including proteins, amino acids and carbohydrates. The purpose of the work and the tasks of research were set. The purpose the work was introduction of advanced technology in production compound feed in the form blend of crumbs and determination of their zootechnical quality. The generalization of the conducted analytical and experimental studies allowed develop the advanced of technology granulation in the form blend crumbs, which will increase the output of finished products. Was developed biological value assessment and аssessment of livestock value compound feed in the form blend of crumbs. Studies have been conducted. Experimental studies were conducted at the Odessa National Academy of Food Technologies. Industrial approbation of the developed, advanced technology production compound feed in the form blend of crumbs, was done in industrial conditions of a branch of a public joint stock company "State Food and Grain Corporation of Ukraine" "Izyumsky plant bakery products". A biological experiment was conducted on laboratory animals at the base of the biochemistry laboratory of the Institute of Dentistry and Oral and Maxillofacial Surgery of the Academy of Medical Sciences of Ukraine. Zootechnical studies, to evaluate the productive action effectiveness compound feed in the form blend of crumbs for young broiler chickens, were carried out under industrial conditions of the "Grain Club". Thus, еfficiency of use compound feed in the form blend of crumbs, has been evaluated in experiments on white rats Wistar line (biological assessment), and Cobb 500 cross broiler chickens (zoological assessment).
Highlights
The feed industry, like many other sectors of the food and processing industry, is experiencing significant changes
Аodder additives, premixes and feed mixtures from Europe and China are imported in Ukraine
Among the main drawbacks of using traditional granulation technology are the following: with traditional granulation technology, the yield of granulated crumb is low in percentage terms, which leads to the re-granulation of the product of the mealy fraction, which increases the unit cost of electricity for the process
Summary
The feed industry, like many other sectors of the food and processing industry, is experiencing significant changes. The existing domestic technological lines for granulating and pelletizing сompound feeds have a relatively high productivity and, at the same time, a high energy intensity for producing granulated сompound feeds. The practical application of the pre-expanding before granulation has established itself thanks to positive indicators This process provides sanitized сompound feeds without destroying vitamins and nutrients. In the product that is processed in the expander, you can add a large amount of liquid components (up to 15-20%), while sometimes there is a need to dry the processed product With this processing of сompound feed in the expander, the performance granulator increases significantly. On the basis of the conducted literature and patent examinations should be said that the development of technology to improve the granulation process will improve the nutritional and sanitary quality of сompound feed products, but will increase the productive effect of сompound feeds and reduce the specific energy consumption. The research objectives have been defined: - to development improve granulation technology for production compound feed in the form blend of crumbs; - to carry out biological value assessment compound feed in the form blend of crumbs. - to carry out аssessment of livestock value compound feed in the form blend of crumbs
