The article presents the study of carcass and meat quality of ST and DM-1 pig breeds, and the hybrids obtained with the participation of Landrace and Pietrain breeds. Crossbred gilts significantly superiors to counterparts in all parameters of meat performance
Experimental studies were carried out on the breeding
farms of "Russian pork" in Millerovo district of the
Rostov region on purebred and crossbred animals
derived from crosses of pigs and the Don steppe types
of meat, breeds of Landrace and Pietrain. The Don
type of meat was used in the experiments as a control.
When crossing, the DM-1 pigs were used as the parent
form, and CT as a father to give twin breed hybrids
DM-1 x ST. The recent delivery of boars of Landrace
and Pietrain breeds allowed to receive twin breed
hybrids of genotypes of CT × L and DM-1 × P
Results of studying of meat efficiency of bull-calves Kazakh white-headed, Kalmyk and Simmental breeds.
Features of formation of meat qualities of bull-calves in the conditions of the Bottom Volga region are considered
Acidic properties of the mineral matrix of meadow
chernozem and meadow-boggy soils of Krasnodar
region are characterized by a total adsorption capacity
of ammonia in the range of 32-61 µmol / g. The lowest
acidity of the matrix was observed under conditions of
permanent rice cultivation for 80 years (32-
33 µmol NH3/g). The mineral matrix of rice soils
depends on the meliorative state and the granulometric
composition of these soils. At low fields of meadowboggy
soils, heavier in granulometric composition, the
total acidity of the mineral matrix is 51-
53 µmol NH3/g on high checks of lighter meadow
chernozem soils – 34-45 µmol NH3/g. In the upper
soil, with a less acidic matrix, the Fe3+ content
increases and the amount of Fe2+ decreases. The
reverse pattern is found in the lower soil with more
pronounced acidic properties of the matrix. A
proportional relationship between the humus content
and the acidic properties of the mineral matrix is
found. The highest yield of rice is formed on meadow
chernozem soils with a less acidic mineral matrix
Methodological and productive and economic aspects of the developed system of the organization and management of harvest-procuring of a grain yield and sugar beet, and a problem of interdepartmental interaction are analyzed. The innovative approach to increase of efficiency of harvest-procuring in plant growing in modern conditions is offered

Maria Callas is the new wine high-grade fragrant pink-berry breed, bred in Greece by Panteley Zamanidi, Leonid Troshin and Alexander Isachkin in 2003 by mating of Greek breed of Roditis with Traminer pink. Under morpho-physiological characteristics, it is included in ecological and geographical group of breeds of the Western Europe. Duration of productive phase is 146-155 days. A breed is strong grown; a degree of ripening of a vine is very high. Productivity is high. The medial mass of racemations is 180 gr. Differs with high winter-hardiness, drought resistance and raised sustainability to fungous diseases in comparison with breeds of Vitis vinifera. The flower is bisexual. A racemation is medial, conic with medial denseness. Bacca is medial, oval, pink color, with a dense wax coating. Peel is tight. Pulp is juicy with strongly expressed high quality flavour. Sugar content is high. Baccas become dry and raisin-like when overrippen and are duratingly maintained on scrubs: sugar content thus attains more than 30 %. The breed is designed for production of dry white wines of excellent quality, and also high-grade dessert and sweet wines; it is applicable for production of high-grade juice, compotes and jam as well; at drying of baccas the raisin of high quality with fragrant tender tang is gained
We have studied the influence of dietary probiotics and metal salts, iron and copper, as detoxifiers for the negative factors which adversely affect the sanitary condition of feeds for farm animals. The optimal doses of detoxifiers in the food infected with mold
due to storage conditions were found. The positive effect was, on average, 8%
The article deals with the modelling of the ecological soil fertility in two types of soil (alluvial-meadows and dark brown soils) under vegetable soils which had been constructed in the Autonomous Republic of Nakhchivan. In the content of the work the ecological conditionus which effects the model soils, physico- chemical properties and capability had been analuzed, the ecological soil fertility modelling in two tupes of soil of the Autonomous Republic had been constructed.As a rezult, the theoretical and practical significance of the ecological fertility modelling which had been constructed in two types of under vegetable soils in the Autonomous Republic of Nakhchivan
