ACTUAL PROBLEMS IN ORGANIZATION OF FEEDING IN MODERN CONDITIONS
06.00.00 Agricultural sciences
DescriptionModern 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

06.00.00 Agricultural sciences
DescriptionThe modern requirements of intergovernmental standards to the quality and safety of livestock produce provide for the use of highly productive animals capable under small expenses to produce more the high quality produce. In particular, at the formation of meat productivity at pigs the great significance has an achievement of optimal digestion and assimilability of consumed fodder means. In the connection, the study of digestion of meat and bone meal from slaughterhouse wastes of cattle (MCM) and poultry (MCBM) presents the scientific interest. In the fodder experience on the growing pigs with the fistula of iliac intestines there was investigated the digestion of two types of meat and bone meal from slaughterhouse wastes of cattle (MCM) and poultry (MKBM). The iliac accessibility of amino acids of meat and bone meal found itself too low: 49,3 % - 69,3 %. The accessibility of general protein reliably did not differ from the average accessibility on main amino acids - 61,5 %. To count the real iliac accessibility of raw protein and amino acids of meat and bone meal there was determined an endogenous emission of these substances on the casein diet. The real iliac accessibility of protein and individual amino acids did not leave the limits in 73% on МCM and 69% - on МCBМ. The accessibility of lysine, leucine and isoleucine MCBM is reliably higher than the same in MCM (P

06.00.00 Agricultural sciences
DescriptionIn 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
DescriptionThe 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
DescriptionUnder 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

DescriptionThe obtaining of high-quality meat is impossible without providing of full value feeding of agricultural animals in the combination with the maintenance of conditions of their feeding. In farms of the Krasnodar region the seeding of forages with molds varies from 103 to 107 КОЕ in 1 gm of forage. There was conducted the study of influence of feeding of animals with mold mixed fodders on the seeding with microscopic fungus of tissues of inner organs. There was carried out the slaughter with the aim of study of meat quality, immune hematological large part of intestines. There were selected the samples of meat and inner organs on the seeding with microscopic fungus. There was determined that in tissues of inner organs of animals which during 4 months were on the ration including the mixed fodder with general seeding with mold fungus 105 -106 КОЕ in 1 gm of forage, there were found the spores of molds. Also there was determined the intensity of animals’ growth of first and second groups reliably did not vary (p>0,5). There were worked out the ways of improvement of sanitary condition of fodders by the means of introduction of the salts of microelements into rations such as bluestone and ferrous sulfate with the addition of probiotics KM3(cultured milk fermentation including Streptococcus lactis, Lactobacillus acidofilum) influencing the growth of pigs, the condition of their health and the quality of meat raw at the using of fodders dirty with micromycets. The consumption of fodders attacking with microscopic fungus with the addition KM3 showed that the lacto- and bifidus bacteria KM3 suppressed the development the pathogenic microflora of gastrointestinal tract of pigs. There were determined the optimal doses of the introduction of detoxicants in fodders affected with molds of storage. The positive effect in average amounted 8%
