Researches were spent in the conditions of the branch of FGBOU VPO «Orenburg State Agrarian University » of the Ilek zoo technical school and on the chair of noncontagious illnesses of animals at Orenburg State Agrarian University. The absolute and relative growth of the weight of a pancreas in ontogenesis was studied. All facts are subjected a statistical processing and during development the absolute and relative growth of the weight is established
In this article, we discussed the problems of the metabolic disease of cows in peripartum period and profitability of the consequent lactation. The article has materials about adaptation in postpartum and arise ketosis, acidosis, laminit and reproductively reasons
It this article, the situation in dairy practice with nutrition factors caused metabolic diseases such as ketosis, acidosis, lameness and a decline in fertility is shown. The article has the proposes on the nutrition of highly productive cows in transition period
Adventive weeds control using classical approach of biological protection against adventive species is not always satisfactory. A new method of the ragweed inhibition is developed that is based on shifting of the natural phenological stage of the phytophage growth. It makes possible to produce a large group of ragweed noctuidae under laboratory conditions on an artificial nutrient medium and to inundate weed infested areas with them by the time of the invader emergence

During cultivation in the glucose-mineral medium, Escherichia coli M-17, O75, â„– 14 and VL 613 and Salmonella enteritidis excrete amino acids, their composition and dynamics depend on the species and the strain identity. The total concentration of the ami-no acids for probiotic strains was higher than oppor-tunistic. Comparative analysis of the amino acids to their ability to influence the growth of bacteria, sug-gests that amino acids are carry out certain regulatory functions
