EVALUATION OF A PROTOTYPE SPREADER IN THE DISTRIBUTION OF POULTRY MANURE

Applied Engineering in Agriculture, 2002
A study of a prototype spreader evaluated the distribution of four poultry manures differing in terms of composting degree and moisture content. The chemical and physical properties such as wet bulk density, moisture content, and static frictional characteristics of the manures were evaluated. The prototype was set up for orchard and arable crops and

Anaerobic Digestion of Poultry Manure

World's Poultry Science Journal, 1963
The process is described and the parameters to be optimised are noted. A design similar to a municipal heated, mixed, fixed cover digester is presented. It is calculated that at a loading rate of 3.2 g VS/l/day and a 23 day detention time that the digester capacity required per hen is 10.5 liters.

Agronomic effectiveness of poultry manure composts

Communications in Soil Science and Plant Analysis, 1995
Abstract Two field experiments were conducted to examine the agronomic value of poultry manure composted in the presence of both phosphate rock (PR) and elemental sulphur (S°) (sulphocompost) and PR alone (phosphocompost). Winter cabbage and summer maize were used as test crops.

Overland Flow Pretreatment of Poultry Manure

Journal of the Environmental Engineering Division, 1978
The overland flow pretreatment process for poultry manure resulted in 77%, 69%, 66% and 56% mass reduction of COD, TOC, TKN, and TP, respectively, after 30 m of flow.

Poultry Manure Composting: An Exploratory Study

Transactions of the ASAE, 1989
ABSTRACT Type of amendment, mixing method and initial dry solids content had the most significant impact on rate of poultry manure composting out of the seven controllable factors tested. The C/N ratio, stirring frequency, and particle size had the greatest impact on nitrogen retention. These conclusions are based on the two levels that were tested for

CHLORTETRACYCLINE IN SOIL AMENDED WITH POULTRY MANURE

Canadian Journal of Soil Science, 1981
Poultry manure from birds fed a ration containing 11 μg chlortetracycline (CTC)/g feed contained 22.5 μg CTC/g. Recovery rates of CTC added to manure were low (22–28%), so 22.5 μg/g must be considered a low estimate. When manure containing CTC was added to soil, no CTC was recovered at manure to soil ratios greater than 1:10.

Evaluation of Poultry Manure as a Feed Ingredient

World's Poultry Science Journal, 1974
Dehydrated poultry manure contains about 10% true protein, which may contribute significant amounts of essential amino acids and a significant level of phosphorus in formulated feeds.

Avoiding pollution from poultry manure

World's Poultry Science Journal, 1993
In the UK the poultry industry has a good record with regard to surface water contamination and has been responsible for only a small proportion of the total pollution incidents attributable to agriculture. Guidance is provided to farmers by a Code of Good Agricultural Practice for the Protection of Water.

Evaluation of the nitrogen content in poultry manure

World's Poultry Science Journal, 2003
Proper estimation of the nitrogen (N) content of poultry manure and proper manure handling are necessary to ensure that application rates minimize emissions from the manure and nitrate leaching int...

Ensiling Poultry Manure as a Feedstuff for Ruminants

American Association of Bovine Practitioners Conference Proceedings, 1975
The nutritional value of poultry manure has been well documented by many researchers but Fontenot, et al., at Virginia Polytechnic Institute has done more in recent years to substantiate the nutritional value of poultry manure in ruminant feeding.
