Coliforms, enterococci, thermodurics, thermophiles, and psychrophiles in untreated farm pond waters.
Untreated waters from ten farm ponds located in central, north central, southeastern, and southwestern Ohio were examined for numbers of coliforms, enterococci, thermodurics, thermophiles, and psychrophiles. The median population densities per 100 ml water for all ponds were: coliforms, 23; enterococci, 3.6; thermodurics, 6,000; thermophiles, 450; psychrophiles, 1,000. The results indicate that...
The economic transition in Eastern Europe and the former Union of Soviet Socialist Republics (USSR) during the last decade has profoundly changed the agricultural sector and the well-being of people in rural areas. Farm ownership changed; selected farm assets, including livestock, were transferred to farm workers or others, and the social and service structures of rural society are in a state o...
Livestock production is the most important component of northern European agriculture and contributes to and will be affected by climate change. Nevertheless, the role of farm animal genetic resources in the adaptation to new agro-ecological conditions and mitigation of animal production's effects on climate change has been inadequately discussed despite there being several important associatio...
BACKGROUND In 2007, the Food and Agriculture Organization of the United Nations (FAO) initiated the Global plan of action for Farm Animal Genetic Resources (FAnGR). The main goal of this plan is to reduce further loss of genetic diversity in farm animals, so as to protect and promote the diversity of farm animal resources. An important step to reach this goal is to monitor and prioritize endang...
Antibiotics present in the environment are recently considered as emerging contaminants, and have raised increasing concerns about their potential risks to ecosystems and human health. In addition to the utilization for treatment, antibiotics are also routinely added as supplements in livestock feed to promote animal growth. A portion of the administered dose used for these purposes can be excr...
In this modern era, every passing day reveals a new invention to the world. Every invention gives us new school of thought and with every invention challenges also increase. We can observe and control the system by using the invention of remote control. To control a system automatically, monitoring is mandatory for efficient control. According to changing setup, control is possible by remote mo...
The levels and composition of agricultural dusts are influenced by animal species, production strategy, housing type and ventilation efficiency. Agricultural dust within animal houses is complex and consists of feed particles, microbes and their products, dander, fecal matter, gases, metals and other organic and inorganic components. Livestock and poultry production facilities may be categorize...
BACKGROUND The protective effect of farm upbringing on allergic rhinitis is well known, but how upbringing in other environments influences the development of allergic rhinitis is scarcely investigated. The aim of this study was to investigate the association between place of upbringing and pet keeping in childhood and allergic rhinitis and nasal symptoms in adulthood. METHODS The population-...
The growing awareness on the multiple environmental impacts of livestock production has risen the necessity to widen the definition of efficiency to a multidimensional eco-efficiency concept. Our paper suggests a combined approach of a whole-farm agronomic model and frontier efficiency method to explore deeply the determinants of eco-efficiency. The whole-farm model used, GAMEDE, is randomly pa...
There is a school of thought that future demand for meat and other farm animal products is unsustainable for several reasons, including greenhouse gas emissions, especially from ruminants; standards of farm animal health and welfare, especially when farm animals are kept intensively; efficiency of conversion by livestock of solar energy into (human) food, particularly by pigs and poultry; water...
