The breed is a factor that determines the productivity of cattle. In the domestic and foreign literature there are numerous data on the economic characteristics of meat breed cattle but there is little reliable information about the productive features of a particular breed in the conditions of a certain region. In this regard the study of the productivity of beef cattle of different breeds in the conditions of the Kurgan region is an actual problem. The studies were conducted in the farms of Kurgan region in 2013-2014 on the young Aberdeen-Angus and Hereford breeds. It was established that the main reserve of beef production in Kurgan region is the intensive growing and fattening of the young Aberdeen-Angus and Hereford breeds (31.53 and 63.51% respectively, of the total number of livestock). The animals of the Aberdeen-Angus breed showed better productivity and economic efficiency in comparison with the Hereford animals: a body weight of 524.55 and 476.80 kg in 18 months, a slaughter yield of 61.2 and 60.8%, a protein conversion ratio of 16. 31 and 16.15%, the level of profitability of 20.98 and 13.91% respectively. During the entire period of cultivation (0-18 months) the animals of the Aberdeen-Angus breed consumed a smaller amount of EFU (energetic feed unit), exchange energy and digestible protein per 1 kg of body weight growth -6.23 EFU, 62.25 MJ and 540 g. The breed factor influences a significant effect on the average daily weight gain (12.82%), dry matter content in the pulp (42.27%), fat content in the pulp (73.72%), energy value of the pulp (58.95%), conversion rate of the energy exchange (59.14%). To increase the production of beef in Kurgan region it is recommended to breed the animals of the Aberdeen-Angus breed.

The main component of waste water of livestock enterprises is the urine of cattle and pigs. The chemical composition of urine is determined by diet and animal species and can not be changed under any techniques. Analysis of water balances allows to make the conclusion that the termination of the reset of highly concentrated waste water by recycling in hydroponicum opens up the prospect of the creation of undrained water supply in animal breeding farms. The use of household waste water for the purposes of technical water supply will allow dramatically reduce the withdrawal of fresh water from a natural water pool, and discharge into it of waste water. Implementation of complex of measures on rational use of water in livestock enterprises allows to move from the closed water systems of individual plants (production of green feed by hydroponic method) to undrained water supply enterprises at all.

The authors of the article consider the problem of protection of water bodies from pollution by oily wastewater from the territory of enterprises of the agro-industrial complex engineering and technical systems. A resource-saving technology for this wastewater treatment using multicomponent sorbents has been developed.

More than 75 % of the drinking water demand in the territory of the former USSR is met by underground water reserves. Along with a serious approach to the pollution of surface waters, soils, atmospheric air, the ecological state of underground waters is given an unjustifiably small importance. The availability of fresh, environmentally friendly water in sufficient quantities is the basis for the life of both humans and all ecosystem participants. The current ecological situation in the Shchuchansky district in the Kurgan region is formed under the influence of numerous factors of natural and manmade origin. The purpose of the research was to assess the quality of underground water located on the territory of the Shchuchansky district in the Kurgan region. The theoretical material of the ecological state of the territory in the Shchuchansky district has been presented in the article. Descriptions of laboratory studies of underground water have been given, and sources of pollution have been indicated. The conducted evaluation of the quality of underground water according to hydrochemical indicators did not reveal the excess of permissible concentrations of pollutants. The underground waters of Chumlyak, Kolmakovo-Miasskoye and the town Shchuchye are more susceptible to pollution. The lowest content of chlorides and sulfates in wells and boreholes has been found in the Petrovskoye and in the Puktysh, nitrites and nitrates in the Nikitino, and ammonium nitrogen in the Naumovka. Studies of the concentrations of heavy metals in underground sources have been shown an increased iron content in them at the level of 1,1-1,6 maximum allowable concentration. The content of copper, zinc and manganese in underground waters did not exceed the maximum allowable concentration. The highest concentration of copper has been found in wells and boreholes in the Kolmakovo-Miasskoye, and manganese in boreholes in the town Shchuchye.

During the operation of poultry farms a large amount of poultry manure is accumulated. Surface wastewater from landfills for storing poultry manure can become the main source of pollution of natural waters. Thus, one of the most important problems of environmental protection is the development of effective systems for protecting aquatic ecosystems from pollution by waste water generated at landfills for storing poultry manure. The purpose of research was the analysis of water protection systems for treatment of surface wastewater from the territory of poultry farms. The authors of the article consider the problem of protection of water bodies from contamination by surface wastewater from the catchment area of poultry farms. The example of surface wastewater from the catchment area of the poultry farm “Sverdlovskaya” has shown the negative impact on water ecosystems. Our own studies of snow contamination from the catchment area of the poultry farm have shown a high content of not only organic and biogenic substances, but also heavy metals. A biotechnology of wastewater treatment using natural ion-exchange materials, followed by bioregeneration of the latter by higher aquatic vegetation, has been developed. The use of an accumulative phytofilter is an effective method of protecting water ecosystems from contamination by surface wastewater from catchment areas of poultry farms, and the design ensures not only the environmental friendliness of the technology, but also naturally fits into the landscape of the area.
