CONCENTRATION OF NUTRIENTS AND MACRONUTRIENTS IN MUSCLE AND LIVER OF YOUNG GEESE FED COMPLETE FEED WITH DIFFERENT LEVELS OF CRUDE FAT

abstract 1201606062 issue 120 pp. 914 – 923 30.06.2016 ru 66
The aim of the research was to study the impact of starter complete feed (CF) with different levels of crude fat on the chemical composition of muscle tissue and liver of young geese. During days 5-28 the poultry was fed CF with 5.1-8.1 % crude fat, from 29- to 60- day age – with 5.4 %. By increasing the level of crude fat in starter CF there was a trend to an increase of the phosphorus content in muscle samples of geese hip and thigh - by 4.4-9.6 %, in the liver - by 27.2-53.5 % (P≤0,05). The chest muscles of the young geese fed high-calorie CF had 2.8-6.0 % higher fat content, than that of counterparts in the first group. At the same time, there was a tendency to a decrease in the concentration of fat in the muscles of the hip and thigh - by 1.9-5.0 % (P˃0,05). Increased level of crude fat in CF did not have a negative impact on the accumulation of heavy metals in the muscle and liver of geese, the concentration of the studied elements was within the permissible level established for food products

ISOLATION AND SELECTION OF THE NON TRANSDUCING E. COLI BACTERIOPHAGES FOR ANTI-COLIBACILLOSIS DRUGS

abstract 1221608040 issue 122 pp. 554 – 566 31.10.2016 ru 140
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

METHOD OF INCREASING THE PRODUCTIVITY OF BROILER CHICKENS THROUGH THE USE OF FUNCTIONAL ADDITIVE

abstract 1211607120 issue 121 pp. 1897 – 1906 30.09.2016 ru 68
In the experimental work, we studied the effect of the inulin prebiotic on the growth, development and efficiency of growing broiler chickens of the Isa cross. In accordance with the scheme of the experiment, the first control group was fed a complete feed (CF) by periods of growth. In the second group, inulin was added to the CF for the first 21 days of growth. In the third group prebiotic was added to the CF at the same rate throughout the whole period of rearing the chicks (42 days). In the second and third groups, we found the tendency to increase the intensity of growth rate in poultry by 1.6 and 3.0%, respectively, compared with the control. Feed costs for weight gain were decreased by 2.1-2.7%. In the chime of the blind processes of the intestine of the chickens of 2-3 experimental groups it was found the reduction of staphylococci and enterococci CFU, while similar to the control group lactobacilli CFU. The muscle tissue in the chickens of experimental groups had greater protein content. The optimal range of indicators is the use of inulin for the first 21 days of rearing poultry. Because of the production audit, an increase in live weight of chickens was found, in the experimental group by 2.7% (p ≤ 0.05), a decrease of feed costs by 7.5%, increase of the survival rate of poultry by 2.0% and profitability by 3.1%

RESOURCE-SAVING APPROACHES TO THE POULTRY FEEDING

abstract 1151601001 issue 115 pp. 1 – 10 27.01.2016 ru 243
The experiment studied the use of an herbal component in feeding of young geese, consisting of hay meal and alfalfa juices coagulate. The replacement of 50 % of complete feed by the studied feeding stuff reduced the protein content in the diet by 9.9-14.9 % and increased the content of crude fiber 1.76-2.01 times. Gross weight gain in the experimental group decreased by 3.9 %, with an increase in feed cost by 17.1 %. However, carcasses of geese in experimental group increased absolute weight of muscles of the breast and legs by 28.6%, and the relative – 5.6 % (Р˃0.05). Using of herbal ingredients tended to increase the yield of dressed carcass by 4.8 %, while the share of internal fat and skin with subcutaneous fat was decreased. There were no differences in the chemical composition of poultry muscle tissue in the groups. Using of herbal ingredients decreased the cost of 1 kg of feed by 0.7 rubles, but the cost price of weight gain increased by 5.0 %. It was concluded that it is necessary to carry out additional studies involving the feeding of poultry with the identical by nutritional value compound feed with the additive under study or without it

THE APPLICATION OF THE BACTERIOPHAGES TO COMBAT COLIBACILLOSIS AND CAMPYLOBACTERIOSIS IN POULTRY

abstract 1231609029 issue 123 pp. 421 – 432 30.11.2016 ru 104
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

THE QUALITY OF THE MUSCULAR TISSUE OF YOUNG GEESE

abstract 1301706016 issue 130 pp. 243 – 252 30.06.2017 ru 83
The article presents the materials of research on studying of influence of various levels of crude fat in the complete feed (CF) for the young geese of Lindovskaya breed on chemical composition and organoleptic quality of goose meat. In the experimental groups we increased the concentration of crude fat in the start and finish of the CF to 7.4 % and 6,85 %, respectively. As the lipid supplement, we used sunflower oil. It is established that muscle tissue of geese, consuming finishing CF with sunflower oil, has a more pronounced taste, odour, tenderness and juiciness. We may highlight the tendency to increase the proportion of monounsaturated oleic acid, in the background of the decrease of specific weight of palmitic acid in the fat muscle 60 day goslings who received the start and finish of CFs with the addition of sunflower oil
