РАЗРАБОТКА ТЕХНОЛОГИИ ПРИГОТОВЛЕНИЯ КОРМОВОЙ СМЕСИ С ИСПОЛЬЗОВАНИЕМ ВТОРИЧНЫХ СЫРЬЕВЫХ РЕСУРСОВ

Abstract

In order to supplying animals with natural vitamins round all year providing and the volume of lowvalue coarse feed without additional energy intensive treatments increasing, feed mixture preparing by the hydroponic method’s technology has been developed. The crushed straw and green fodder grown from cereals or legumes’ components for this mixture are used. The green fodder’s traditional hydroponic cultivation without substrates has root system mass’s large losses, but also does not ensure the plants’ full development. The substrate using in this case by difficulty of root system cleaning is limited. In proposed technology, straw acts not only as a feed mixture’s component, but also as a root habitable base. The rational technological parameters of the affecting green feed highest yield’s production have been determined experimentally. It grain soaking, cultivation, temperature and surrounding air’s humidity, the starting material’s sowing rate and illumination’s duration is included. The straw layer’s waterphysical properties as a root habitable base, its porosity, density and capillary moisture capacity have been studied. An experimental comparison of green feed yield obtained by the proposed technology and the traditional method using has been carried out. The analysis showed that green feed yield increasing is primarily due to root mass’s yield increasing and root habitable base’s water air nutrition has improved. According to the proposed technological scheme, the design of feed mixture preparation’s installation has been developed. This installation’s main structural elements operability has been confirmed experimentally, and the parameters of individual working bodies have been substantiated. Recommendations on the proposed technology using and installation’s design for feed mixture preparation are given. The analysis of the experimental results was carried out, and the corresponding conclusions were done: design solutions using for technological process’s organization at feed mixtures production can significantly reduce final feed products’ cost, and consequently, livestock production’s cost as a whole. The directions of further work on this issue have been determined.
