| Popis: | Studies of additives (copper chelate, pure culture of microorganisms micromycetes Trichoderma harzianum F114, enzyme preparation of b-mannanase) were carried out. Chelated compound of the trace element copper, its physical and mechanical properties, namely humidity, angle of repose, bulk density, hygroscopic point, average particle size were considered. The technique of cultivation of the microscopic fungus Trichoderma harzianum F114 is presented. The determination of the physical and mechanical properties of the enzyme preparation of b-mannanase (humidity, angle of repose, degrees, bulk density, average particle size, conditional caking) has been shown in the work. For the experiments, we used arbitration methods for assessing the quality of research objects. The components of the premixes should be stable during storage, should not have a pronounced aggressive effect on other biologically active substances, should be evenly distributed in the mass of the finished product, and have a high digestibility for the animal's body. It has been established that the introduction of the studied ingredients into the composition of the premix formulation will not have a negative effect on the quality of the premixes and compound feed. |
