Description
The article demonstrates the results of therapeutic and preventive effectiveness of the use of lactic acid bacteria – Lactobacillus brevis and Lactobacillus parabuchneri in laboratory animals, in particular mice and rats. They were isolated from the gastrointestinal tract of a wild quail in experimental violation of the intestinal microbial background. Artificial imbalance of the intestinal microbiota of experimental animals was caused by the use of the antibiotic. As a result of tests it was established that the application of probiotic cultures improved microbial disorders of the gut, however, the use of their consortium in the probiotic promoted consistent clinical result characterized by an elevated level of representatives of the normal flora (lacto- and bifidobacteria) and reduction of the number of representatives of pathogenic and conditionally pathogenic microbiota, with subsequent achievement of a level characteristic of healthy animals

Description
In the article we present the results of perennial researches on the influence of norms of fertilizers on growth and productivity of sunflower on Chernozem (Black soil) with different levels of fertility in the Central zone of the Krasnodar region. The improvement of nutritional status of plants promoted increase in leaf area of sunflower in the flowering stage from 20.1 to 30.8 thousand m2/ ha and more accumulation of dry substances and major nutrients in plant tissues throughout the growing season. The greatest influence on the content of nitrogen and phosphorus in the leaves of 56 – 64 and 50 – 58%, in stalks of 40 – 62 and 39 – 42%, in baskets 43 – 59, and 38 -68%, respectively, provided the rate of fertilizer. The yield of sunflower seeds in average for three hybrids (Kubanskiy 341, Triumph, Legion) evolved in experiment parcels from 25.5 to 33, 4 ac./ha. The highest productivity of this crop is obtained when a high rate of fertilizer (N80Р120) is applied on soil with a high level of fertility. The increase of seed yield compared to control was 7.9 ac./ha or 30.9 %. While increasing the level of soil fertility and fertilizer amount, oil content of the seeds decreased from 46.9 to 44.5%, but the yield of oil increased from 1.20 to 1, 47 T/ha due to the growth of productivity

Description
Plants of winter wheat suppress weeds quite well, however, the use of herbicides is required, which prevents the new clogging up of soil. Under surface tillage it was observed a greater spread of weeds than under mold-board plowing. Introduction of the herbicide Lancelot regardless of ways of tillage has reduced this rate in 5.8 times. An important means of regulating of vital functions of soil microflora is tillage. 40% of all expenses ac-counted for the soil treatment required for cultivation of crops. Therefore it is important to study the effect of tillage on the course of microbiological processes in the upper 0-30 cm layer. The intensity of the decomposition of plant material by linen cloths method objectively reflects the status and activity of soil microflora. One of the signs of cultural soil condition is its ability of nitrification. Nitrification process is particularly slow in early spring, because this time the microbiological activity is weak because of low soil temperature. When the soil is progressing the number of nitrates increases and reaches its peak in summer, after that the process is fading. Studies have shown that under surface tillage, microbiological processes of decomposition of cellulose and the ability of soil nitrification compared with moldboard plowing are higher. The components of yield structure show features of yield formation. Tillage did not have an essential effect on crop structure elements. Application of herbicide Lancelot has significantly increased the number of productive stalks (7.3-10%) and mass of 1000 grains on 1.8 g or 4.5%. Grain yield of winter wheat did not depend on the primary tillage (57.5-56.5 kg/ha). Application of herbicide Lance-lot has allowed to receive allowance (on average for 2 years) 5.0 kg/ha. Grain quality indicators of winter wheat depend both on the hereditary traits and preferred growing conditions. The amount of gluten is not dependent on the main tillage, while the introduction of herbicide has increased gluten to 1.4%. Calculation of economic and bio-energy efficiency showed that the use of surface treatment in the cultivation of winter wheat on soil ordinarily is worthwhile

Description
The experiment has examined the effect of various agricultural technologies on the yield of winter wheat, depending on the factors studied. The studies were conducted at the experimental station of the Kuban State Agrarian University under the conditions of multifactor multi-year monitoring. The experiment was carried out in a typical for the zone 11-field grain-grass-tilled crop rotation. In this paper, we considered some of the elements of the winter wheat cultivation technology, the Brigade variety using different doses of fertilizers (N50P50K120 and N100P100K240) on four tillage options (plowing, chisel loosening, disc peeling and zero tillage). On the basis of the conducted research, it has been established that in order to obtain a stable harvest of winter wheat grain, higher doses of mineral fertilizers should be applied, which also ensures high indicators of grain quality. The considered agrotechnical methods led to a positive change in crop structure and grain quality

Description
The aim of the following research is the studying of the efficacy in probiotic drug Probiolact (0.5% and 1.0%) usage, being in combination with Milkshake supplement. The given complex mixture is meant for medicative-phylactic purposes focused on the reduction of young ones death rate owing to gastro – intestinal diseases when neo-natal period. It is specified that the above-mentioned mixture affects the livestock indices. Thus, the average growth of baseline for the period of 30 days experimenting has been 7.4 kg, whereas in 2 tested groups it accounted for 10.3 kg and 11.6 kg, consequently. Therefore, the best possible daily phylactic doze of Probiolact (1%) and Milkshake mixture demonstrates the positive effect on the pro-cess of bifido- and lactoflora formation in calves’ intestinal tract due to normal flora cells quantity increase. With that, intestinal tract contamination level of disease-producing flora gets lower, and the natural resistance of cell-mediated immunity grows. Thus, two major problems of factory farming (i.e. the reduction of young death rate and surplus guarantee) can be solved with giving calves the mixture to drink, along with the first portions of colostrum, and during the following 30 days

EFFICACY OF SUPRANOL AND UTEROTON IN PREVENTION OF ACUTE POSTPARTUM ENDOMETRITIS IN COWS
06.02.00 Veterinary and Husbandry
DescriptionThe article reflects information characterizing the significance of mastitis and endometritis in the indicator of premature disposal of cows from herds of large farms in the western regions of the Krasnodar region: an average of 30% of the total culling of cows. The effectiveness of veterinary measures in Pravoberezhny JSC of the Temryuk district for mastitis and endometritis in cows was assessed: 81-95%; fertilization index value ‒ 1.8; the duration of the service period exceeds the requirements by 20 days. The studies the nature of the influence of the drugs called Sepranol and Uteroton on the calving process and the occurrence of postpartum complications in cows from the herd, which was formed with violation of breeding principles. The use of the drugs Uteroton and Sepranol contributed to a 50% decrease in the calving index in calving cows by 50% compared with the results of the combined use of estrophan and oxytocin. The use of Uteroton reduced the damage from the lack of milk by 87880 rubles, and the use of Sepranol - by 171164 rubles. We have given practical recommendation on the use of Uteroton and Sepranol for veterinary effects on the body of cows in the early postpartum period in order to reduce the occurrence of complications

EFFICIENCY OF ROKSATSIN IN AEROSOL DISINFECTION OF THE LIVESTOCK BUILDINGS
DescriptionThe authors briefly describe the properties of polyhexamethyleneguanidine hydrochloride (PHMG), which refers to a broad-spectrum biocide and has antimicrobial activity against Gram-negative and Gram-positive bacteria, viruses and fungi. PHMG has a deodorizing effect, gives the treated surfaces long bactericidal effect, which can be stored depending on the surface and other external factors from 3 days to 8 months. The authors have presented data about the level of bacterial and fungal contamination of air in the dispensary before and after aerosol treatment of Roksatsin. Bacterial contamination of air dispensary determined via the sedimentation method (Koch Method), which is settling microflora (in air), under gravity, on the surface of a growth medium. For the determination of total bacteria and fungi in 1m3 of air the authors make calculations of total aerobic microbial count (TAMC) according to the formula that was proposed by V.L. Omelyanskii. Bacterial contamination of air was evaluated before disinfection. Accounting quality of aerosol disinfection performed by sedimentation microflora on Petri Dishes through 30, 60 and 120 minutes of exposition. In the analysis of the data the authors defined that Roksatsin as a disinfectant has a negative effect on pathogens, namely significantly reduced the content of pathogenic and conditionally pathogenic bacteria and fungi in the air, so it can be used for preventive and compelled aerosol disinfection of air in the livestock buildings
