Problems of Recycling Manure for Feed Cattle Manure
American Association of Bovine Practitioners Conference Proceedings, 1975Animal waste, what is it? I think today we must pretty well accept, based on the data, that it is are source out of place. It is out of place and many times we don't like to fool with it because it is so out of place. Manure to improve feed efficiency of cattle.

Physical and Thermal Characteristics of Dairy Cattle Manure
Journal of Environmental Quality, 2014Greenhouse and regulated gas emissions from animal waste are naturally mediated by moisture content and temperature. As with soils, emissions from manure could be readily estimated given the physical, hydraulic, and thermal properties are described by models and microbes and nutrients are not limiting factors.

Biomethanation in a thermophilic biotrickling filter using cattle manure as nutrient media
, 2020Hydrogenotrophic methanogenesis is a power-to-gas method, biologically converting CO2 to CH4 using H2 generated from electrical power. However, the low rate of gas-liquid mass transfer of H2 limits the hydrogenotrophic methanogens biocatalyst.

The Water Requirement of the Cattle Manure Ash
Advanced Materials Research, 2011This paper studies the water requirement of the two cattle manure ash in two different experiment conditions. According to the flying ash used in cement and concrete, the water requirement of the cattle manure ash is studied and the flying ash water requirement is compared when two different superplasticizers (the naphthalene-based water reducer and ...

Synthesis and Stability of Dimethylnitrosamine in Cattle Manure
Journal of Environmental Quality, 1976AbstractBeef cattle feedlots are a source of large quantities of organic and inorganic nitrogen compounds, among which are the precursors for the synthesis of N‐nitrosamines, compounds carcinogenic to laboratory test animals and, possibly, to man.Our objectives in this study were: (i) to determine if N‐dimethylnitrosamine (DMNA) and N ...

Environmental Impacts of Cattle Manure Composting
2002Measurement of the losses of nutrients during composting is needed to understand the composting process, to implement methods of nutrient conservation and highlight potential environmental impacts. Cattle manure was aerobically composted under ambient conditions to evaluate composting as a method of manure handling.

Utilization of Cattle Manure for Fertilizer
2019Cattle manure is considered a good "shotgun" fertilizer. Liquid beef cattle manure is produced in beef cattle confinement buildings at the rate of.6 to 1.0 cu ft/hd/day depending upon ration and live weight. Crop yields resulting from application of liquid beef cattle manure have been studied by many researchers.
