ACTUAL PROBLEMS IN ORGANIZATION OF FEEDING IN MODERN CONDITIONS
06.00.00 Agricultural sciences
Description
Modern pig farming is a leading global livestock industry, but the organization of adequate balanced feeding is actual for the industry. Digestibility of metabolizable energy of feed depends on various factors, including the content of non-starch polysaccharides, which have a negative effect on the digestibility of key nutrients of the feed, lead to a decrease in growth rate and conversion efficiency of nutrients. Enzyme preparations which composition generally includes Xylanase, cellulase, β-glucanase activities, may avoid the negative impact of non-starch polysaccharides. Today's promising preparation that combines the functions of two feed additives - feed enzyme and probiotic, is an enzyme preparation Cellobacterin that, due to the particular organization of the enzyme complex, increases the digestibility of barley grain and effectively effects on sunflower meal. As a probiotic preparation it inhibits the development of pathogenic microorganisms and promotes the formation of beneficial microflora in the digestive tract. The introduction of Cellobacterin enzyme preparation into the compound feed with a high content of barley grain and sunflower meal increases the body weight of young pigs by 4.8% and reduces the cost of feed per 1 kg of live weight gain. The results of hematological studies found no significant deviations from the physiological norm in the morphological picture of the blood in experimental animals. The group, where Cellobacterin was added, showed higher vitamin A content by 2.8% as compared to the control, while vitamin E is found in both groups on the same level. Based on the results of the research to improve the productivity and growth rate in compound feed based on barley and sunflower meal with higher fiber content, it is recommended to include in the compound feed Cellobacterin enzyme preparation at the rate of 1 kg per 1 ton of feed

EFFECT OF BENTONITE ON MEAT PRODUCTIVITY AND QUALITY OF PORK GILTS
06.00.00 Agricultural sciences
Description
In our country, great influence is given to the production and consumption of agricultural animals' meat with high consumer qualities. In this regard, the livestock producers, particularly pigs, are to increase production and improve product quality. Works on using some natural mineral complexes - bentonite and zeolites as a source of macro - and trace elements are performed. The aim of the research is to study the effects of bentonite feeding with free access on the meat productivity and hygienic meat quality of young pigs for fattening. Best effect on the slaughter indexes of fattening gilts had bentonite feeding with free access that resulted in significant superiority of the animals in the experimental group over the control counterparts on pre-slaughter live weight, slaughter weight, chilled carcass weight, slaughter yield, carcass length, the "muscle" eye area and the backgammon weight. More favorable effect in the longest muscle on the dry matter and protein synthesis was provided by bentonite feeding with free access. Due to this, the gilts of the experimental group were in significant advance of their control counterparts in concentration of dry matter and protein in meat. Along with this, the longest muscle of young pigs on fattening in the experimental group had the highest protein value, as according to the protein-qualitative indicator the animals of this group were in significant advance of the control counterparts. Feeding bentonite clay with free access had a strong detoxifying effect that is against control counterparts of gilts in the experimental group showed the significant reduce of lead, zinc and cadmium concentrations in the meat

ISOLATION AND SELECTION OF THE NON TRANSDUCING E. COLI BACTERIOPHAGES FOR ANTI-COLIBACILLOSIS DRUGS
Description
The isolation of E.coli phages from samples of natural and waste water obtained during expeditions in the different regions of Russian Federation was carried out. The obtained phages (286 isolates) were tested for their ability to lyse the pathogenic strains of E. coli – pathogenic agents of pig colibacteriosis in Krasnodar region. The study was conducted of their ability to phage transduction, the molecular-genetic characterization and biotechnological parameters of selected bacteriophages. For first experimental design of veterinary drugs was selected 5 coliphages having no ability of plasmids transduction. It has been shown that all the investigated phages are representatives of T4-type phages of family Myoviridae. The reported study was partially supported by RFBR, research projects No. 08-04-99111, 09-04-10132, 16-44- 230855

HEMATOLOGICAL PARAMETERS OF PIGS WHEN USING YAKON TUBERS AND ADSORBENTS IN RATIONS
06.00.00 Agricultural sciences
Description
Under the current conditions, it is very important to boost the production of pork and improve its sanitary and hygienic quality for the successful handling of problems subjected to import substitution of meat products. This can be reached by means of strengthening of food reserve. For that purposes, in the frame of two experiments yacon tubers in combination with enzymatic agent protosubtilin GZx have been introduced in the intakes of fattening pork stores instead of fodder beat, and various doses of carbitox adsorbent have been additionally added when superfluous background of heavy metals was observed. During the 1st experiment, the substitution of fodder beet with the similar quantity of yacon tubers has allowed the animals of experimental group to outweigh the ones from the control group on 7,5% in the terms of gross formation of body weight, and to gain 100 kg of body weight for 7 days ahead of the animals from control group as well. Additionally, fodder costs per product have been reduced and the morphological and biochemical values of animals blood have been optimized. Based on the data from 2 nd experiment, it has been defined that the better dose for feeding of adsorbent carbitox was 2,0 kg per tonne of concentrates thereby the animals of 3rd experimental group had reasonably higher body weight gain and thereby higher feed-conversion ratio by products. Therewith, the animals intermediary metabolism has been speeded up due to optimization of morphological and biochemical values of blood and reduction of heavy metals content in blood serum, in other words level of zinc, lead and cadmium was not exceeding maximum allowable concentration

THE APPLICATION OF THE BACTERIOPHAGES TO COMBAT COLIBACILLOSIS AND CAMPYLOBACTERIOSIS IN POULTRY
Description
This work considers the needs and methods of phage therapy of two bacterial infections in poultry. The review examines the use of bacteriophages, from the moment of their discovery to the present day. We discuss the relevance of such diseases as compilobacteriosis and colibacteriosis transmitted from birds to humans, we show how to use bacteriophages and their efficacy in models of adult birds and chickens, including information provided on the pilot study of phage therapy at a poultry farm. The reported study was partially supported by RFBR, research projects No. 16-44-230855 and No. 13-04- 00991 and № 16-44-230855-р_а

06.00.00 Agricultural sciences
Description
Studied the investigation of the therapeutic effect of experimental mixture of four non-transducing E. coli bacteriophages and it combinations with probiotic, designed on the basis of the endemic Lactobacillus paracasei strain, previously isolated from pigs in this age of the local population in the state, the survival rate and laboratory parameters of pigs with post-weaning diarrhea. The most influence on the correction of E. coli dynamics has a combined oral administration of phage medicine and probiotic preparation established. The most influence on the dynamics of titer phages has not only the combined using (both oral and intradermal) of phage medicine with the probiotic preparation, but also an isolated ingestion of phage mixture
