Problems of Recycling Manure for Feed Cattle Manure

American Association of Bovine Practitioners Conference Proceedings, 1975
Animal 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, 2014
Greenhouse 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.

Effects of chlorotetracycline on antibiotic resistance genes and the bacterial community during cattle manure composting.

Bioresource Technology, 2020
Chlorotetracycline (CTC) is one of the most antibiotics present in cattle manure. In present study, three levels of CTC (0, 20 and 40 mg kg-1) were added to cattle manure composting systems to investigate its effects on the distribution of antibiotic ...

Biomethanation in a thermophilic biotrickling filter using cattle manure as nutrient media

, 2020
Hydrogenotrophic 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, 2011
This 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, 1976
AbstractBeef 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 ...

Pyrolysis study on cattle manure: From conventional analytical method to online study of pyrolysis photoionization time-of-flight mass spectrometry

, 2020
Cattle manure is a kind of abundant agriculture waste but potential renewable resource to be converted into fuel by pyrolysis. The pyrolysis behavior of cattle manure was analyzed by three methods in this work: thermogravimetric analyzer (TG), pyrolysis ...

Environmental Impacts of Cattle Manure Composting

2002
Measurement 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.

Effects of nano-zerovalent iron on antibiotic resistance genes during the anaerobic digestion of cattle manure.

Bioresource Technology, 2019
This study investigated the effects of adding nano-zerovalent iron (nZVI) at three concentrations (0, 80, and 160 mg/L) on the methane yield and the fate of antibiotic resistance genes (ARGs) during the anaerobic digestion (AD) of cattle manure.

Utilization of Cattle Manure for Fertilizer

2019
Cattle 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.
