ECONOMICS
The article proposes a theoretical model of economic regulation of agricultural and industrial production which is based on the author's definition of this concept and includes goals, reasons and necessity for the government’s interference in the economic development of the agricultural sector, methodology and tools of a regulating influence, its main directions and results.
AGRICULTURE AND PLANT CULTIVATION
The paper deals with the analysis of the breeding work on triticale for the period from 1976 to 2013. The main sources of agronomic characters and qualities are presented, the efficiency of their use in breeding programmes based on an improved scheme of breeding process organization is determined. As a result of the breeding, 18 winter triticale varieties and 6 spring triticale varieties have been developed.
ANIMAL HUSBANDRY AND VETERINARY MEDICINE
The research shows that concerning fattening qualities the best hybrids are those obtained in four three-breed crossing variants: (BLW×BM)×L (den.), (BLW×BM)×L (ger.), (BKBçBM)×Y (den.) and (BLWçBM×Yof German breed heterosis effect of which is: 10.2; 9.15; 5.0 and 3.7 %, 8.1; 5.3; 7.9 and 3.4 %, 6.2; 5.7; 5.5 and 3.8 %. Superiority of the Danish hybrids over the control group is also established concerning carcass length by 2.1; 1.2 and 1.7 cm, backfat thickness by 2.8; 1.4 and 2.1 mm, loin area by 5.4; 3.7 and 4.4 cm2 , weight of third part of half-carcasses by 0.6; 0.5 and 0.7 kg, meat content in carcass 1.6; 0.8 and 1.2 %.
The use of organic trace nutrients complex “OMEK” for high performance cows improves milk production, reduces feed costs, improves trace elements digestibility. Feeding calves, piglets and poultry with “OMEK” increases the average daily weight gain of animals and poultry, improves blood biochemical indices and reduces the cost of weight gain.
The article presents the results of the research on the use of linseed cake and linseed oil in feeding of hens. The influence of the feed on hens’ viability, their productivity indicators and quality of eggs is studied. It’s established that the use of linseed cake and linseed oil enables to increase the content of omega-3 fatty acid in eggs from 0.4 up to 3.4–6.4 %.
MECHANIZATION AND POWER ENGINEERING
Modern animal husbandry should react quickly to the requirements of sales market. It is possible with the mechanisms determining the place and time of control actions in a technological chain of production. Adoption of energy saving machines at farms will allow reducing the costs of performing complicated production operations. The paper presents the theory on calculation of a climb angle of a mixer arm. Dependence for calculating the critical angle of lead is obtained.
PROCESSING AND STORAGE OF AGRICULTURAL PRODUCTION
The article deals with the potential risks to the environment and human health from the use of genetically modified plants (GMPs). The effects associated with negative GMP influence on biological diversity as well as negative results of long-term experiments in feeding the animals on the feed with GMP are discussed.
