Description

     . . FIELD OF THE INVENTION The invention relates to PE-based food containing synthetic nitrogen and phosphorus additives and intended for feeding to ruminants. Known liquid feed additive for ruminants based on starch and urea. The method of obtaining such an additive consists in passing an aqueous suspension of crushed starchy raw materials and urea into a hydrothermal cooking pot along with water vapor intended for heating, destruction and gelatinization in a turbulent flow of a source of starch in the presence of a nitrogen-containing substance. . Obtaining such a feed additive according to the described technology requires significant energy expenditures, since it involves the process of heating the starch raw material with water vapor in the presence of WII az from the containing article 1, the Product is obtained in a liquid form that is inconvenient for storage, transportation and distribution. A method of processing and storing feed is also known, where crushed feed is divided into solid and liquid fractions under a pressure of 40-250 kg / cm. The solid fraction is dried. liquid is mixed with solid food and fed to cattle 2. ; The method requires high energy costs, as it includes the drying process. the invention. is to reduce the energy cost of producing nitrogen-phosphorus dietary supplements. animals and their receiving in briquetted or in granulated form. This is achieved by addition of straw chop and orthophosphoric acid to the composition of the feed additive containing the coarse raw material and urea, and mechanically dehydrated potatoes with a moisture content of 50-65% are used as a starchy raw material. , crushed, treated with sulfuric acid or its salts. and divided into dense and liquid fractions. In a dense fraction of potatoes with a moisture content of 50-65%, a mixture of urea and orphosphoric acid is introduced with constant stirring, a straw chop is added to a moisture content of 15-20%, the mixture is briquetted or granulated,

Smoldering of mechanically dehydrated potatoes and straw chopped with the addition of urea and orthophosphoric acid to a moisture content of the mixture of 15--20% and subsequent extrusion reduces the energy costs of producing nitrogen-phosphorus ones. before- . cans, since their production excludes heat treatment. The starchist part of the mechanically dehydrated potatoes in the extrusion process at high pressure and temperature is pasteurized and binds the components of the feed additive into briquettes or granules. This makes it possible to obtain a product in the form of briquettes or pellets convenient for storage, transportation and distribution.

In briquettes or granules, paste starch tightly coats the urea particles, ensuring its slow release and facilitating better utilization of urea nitrogen by the rumen microorganisms.

In the presence of orthophosphoric acid in the extrusion process at high pressure and temperature, the degree of polymerization of the starch and cellulose polysaccharides decreases as a result of acid hydrolysis, which increases the nutritional value of the product and strengthens its structure / increasing the adhesive force between individual ingredients. Some of the polysaccharides are hydrolyzed under these conditions to uncocaricides. Under these CONDITIONS, monosaccharides and orthophosphoric acid react with urea to form glycosyl wine and urea phosphate, which increases the degree of absorption of urea nitrogen by the animal body.

Introduction Preservative in the form of co. leu sulphurous acid at .SulFyg. The tipping of minced potatoes contributes to a better preservation of the feed and an improvement in its color,

 D; 1N nitrogen phosphate additives according to the proposed technology can use standard equipment for the production of briquetted or granulated feed.

The proposed method allows rational use of fodder potatoes and reduces the loss of its dry BeitjecTB during storage.
