“…At the same time, the fatand-oil industry with alkaline refining of vegetable oils as a by-product receives a fatty product -soapstock. Soapstocks contain at least 20 % fat, glycerides, salts of fatty acids, phosphatides, choline, tocopherols, carotenoids, mineral salts [9,13,18]. One kilogram of soapstock contains 8500-8700 kcal of metabolic energy, which is equivalent in energy to 3.4 kilograms of concentrated feed.…”

At the same time, rapeseed meal has an increased nutritional value and is almost completely devoid of the shortcomings that are characteristic of rapeseed cake. However, a small amount of fat limits their use in feed for valuable fish breeds. During the manufacture of fat-and-oil products, fat waste and other products that have a certain feed value are formed. In particular, we are talking about fat processing - soapstock. The feed value of this product has been confirmed by numerous studies and large-scale feeding experiments conducted by the parent institutes of the Ministry of Agriculture and specialized organizations. The article presents studies of the possibility of introducing rapeseed meal enriched with soapstocks into feed for valuable breeds of fish, and also presents the dynamics of quality indicators of the starting production feed for sturgeon fish during storage in warehouse conditions. During the production of mixed fodder, the preparation and supply to the experimental department of the studied products were carried out through the line of cakes. Grinding of granules was carried out on a crusher with a sieve with holes with a diameter of 6 millimeters, a sheet thickness of 4 millimeters. The shredded meal was sent to the silage of the raw material warehouse and then to the naddozer bunker. The supply of loose enriched meal to the production building was similar. Analysis of the data obtained indicates that the introduction of rapeseed meal enriched with soapstock lipids into the feed does not change the quality and does not reduce its shelf life.

The problem of developing highly digestible compound feeds with protected protein for cattle is due to the specifics of the gastric tract of cows and the peculiarities of protein assimilation. Due to the importance of preliminary moisture-heat treatment of grain for the subsequent course of the extrusion process, the treatment was carried out by steam at a pressure of 0.6 MPa before moistening the feed to a humidity of 17-20 % and heating to a temperature of 70-80 ° C. It is established that heat treatment has a significant effect on the carbohydrate complex of grain. Heating it at high temperatures causes the destruction of starch, accompanied by the formation of easily soluble carbohydrates, which has a positive effect on the digestibility of feed. The kinetic regularities of the processes of moisture-heat treatment, grinding and extrusion of grain in the production of highly digestible feed with protected protein for cattle were studied. The degree of dextrinization and the digestibility of starch increased with the heating temperature of corn and its mixtures with wheat up to 100-110 ° C. At the same time, the performance of the extruder was 300-320 kg/h, the digestibility of starch extruded corn and grain mixture increased to 85 and 68 mg of glucose per 1 g of the product (hereinafter mg/g), respectively. For wheat, this indicator is lower and, accordingly, is 50 mg/g. When heated during the extrusion of corn to a temperature of up to 120-140 ° C, the digestibility of starch was 100-110 mg/g, and for the grain mixture – 80-83 mg/g. At this temperature, the digestibility of the starch of extruded wheat corresponded to 60-65 mg/g. The optimal moisture content of feed in the process of extrusion for the purpose of forming pellets is 18 %. Studies of the extrusion effect on the carbohydrate complex of processed feed have shown that the destruction of starch in the extruded product increases. Thus, the content of soluble carbohydrates increases by 27-32 %, and the digestibility of starch increases twice in extruded feed compared to the unprocessed feed.

Currently, fur farming products are becoming more and more in demand. With the increase in the number of fur-bearing animals, it is necessary to produce compound feeds that provide high quality furs with minimal feed costs. Compound feed recipes with a fat content of 20% and higher were developed for fur animals. Feeding fodder in the form of granules produced by the technology, one of the stages of which is the process of granulating compound fodders with a high fat content with reasonable operating parameters of the granulator press, is expedient. Process studies using the method of statistical planning of a multivariate experiment were carried out to determine the optimal granulation parameters. The following factors influencing the process under consideration were chosen: the amount of added fat, the steam consumption, the gap between the roll and the press die. Specific energy consumption and crumbling served as criteria for assessing the influence of the selected parameters, which make it possible to assess adequately the efficiency of the process. The data obtained showed that the process of pelleting compound feed at optimal parameters makes it possible to obtain pellets, the quality of which meets the requirements of the standard. All the data obtained were within the calculated confidence intervals of the optimization parameters. The change in the quality indicators of the obtained granulated compound feed during storage was also investigated in the work. Changes in the quality of granulated compound feed during storage testified that the values of total acidity and acid number of fat increased significantly after two months of storage due to hydrolysis of fat in conditions of free oxygen access. The value of the peroxide number of fat, which reflects the depth of oxidative changes in the compound feed, increased sharply after two months of storage. The content of vitamins A and E during the storage of compound feed for 45 days in summer was 12.3% and 10.5% of the initial values, respectively. The recommended shelf life of granulated feed with a high fat content in winter-spring period is 60 days, in summer - 45 days.
