The article presents the growth and the condition rates of field protection plantings of Lipetsk region, depending on agricultural practices of creation
The role of root and aftermath residues of basic field farm crops for retention and increase in organic matter content of the soil with fertilizing and fertilizer omitted is substantiated in the article. It is ascertained that the quantity of aftermath residues coming into the soil is 2,6-3,5 times less than that of natural vegetation while dry matter is removed with the main production and by-products 2,0-2,2 times more than is remained in the soil
The influence of four experimental phage preparations, designed based on non-transducing E. coli bacteriophages on pigs with post-weaning diarrhea studied. The influence of these phages in depending by methods of its applying (per os and intra cutis) on coli-titer and coli-phages titer studied. It is established, that the best survival rate and the clinical condition showed animals treated with the E. coli phage T4-type with lab. number «8» (till 5,52 lg CFU/g at 37-days age) in parallel with an increase in titer of phages (till 5,73 lg CFU/g at 40-days age). Intradermal (intra cutis) method of applying of experimental phage preparations (constructed on basis of phage “6” and phage “8”) showed the some positive effects on correction of negative dynamics of coli-phages titer in control group

We developed an effective technology of reproduction in meat cattle breeding, which allows rational use of the bulls-producers, to obtain a high output calves (85-95%), to organize the accuracy of the account of the origin of young animals, to improve the level of selection-breeding work on the improvement of productive and breeding qualities of animals and create in a shorter time highly productive herds of meat cattle
In the article, the maintenance of heavy metals in fertilizers is resulted. The quantity of the years providing ecologically safe entering of mineral fertilizers before excess of maximum-permissible concentration of heavy metals in soil is calculated. The balance of heavy metals as micro – and ultra microelements in leached black soil is resulted
