Physiological indices and productivity of chickens depending on biologically active additives

Data are obtained on the positive effect of the enzyme Xybeten-Cel and its combination with flavomycin, Bacell, and Prebio in mixed chicken feeds based on naked oats and wheat on the physiological indices of chickens and egg quality.     

Pedogenetic diversity and the red data soil book for Volgograd oblast

The indices of soil quality have been studied in Volgograd oblast, and the reasons for the worsening quality have been identified for different groups of soils. It is suggested that information on the genetic diversity of soils, their properties, and the character of soil management should be specially collected and systematized in order to make strategic decisions aimed at soil conservation. Information should be separately collected for the soils of agricultural lands, the soils of specially protected natural territories (including the soils listed in the Red Data Book of Russian Soils), and the soils that are used for nonagricultural purposes.     

Combined use of an enzymes with biologically active substances in mixed chicken feeds

Investigations are carried out and results obtained on the combined use of an enzymes with a probiotic, feed antibiotic, and acidulants in mixed chicken feeds. The beneficial effect of biologically active additives on their productivity and egg quality is proved.
