Range use and pasture consumption in free-range poultry production

Animal Production Science, 2013
The recent increase in free-range meat and egg production and consumption has led to extensive investigation in this area and has revealed that the level of animal performance achieved in such systems is low compared with that achieved in conventional production systems. In Australia, this difference has been attributed either to the absence of in-feed

Nutrient losses in surface and subsurface flow from pasture applied poultry litter and composted poultry litter

Nutrient Cycling in Agroecosystems, 1998
Over application of poultry litter may cause pollution of surface and ground water. Spatial variability in soil characteristics makes predictions difficult. Composting poultry litter could reduce the risk of pollution by creating more stable organic components. Three rates of poultry litter and compost (10 Mg ha-1 litter, 20 Mg ha-1 litter and 10 Mg ha-

Prevalence and Characterization of Campylobacter jejuni Isolated from Pasture Flock Poultry

Journal of Food Science, 2010
Abstract:  The growing interest in organic and natural foods warrants a greater need for information on the food safety of these products. In this study, samples were taken from 2 pasture flock farms ( N = 178; feed, water, drag swabs, and insect traps), pasture flock ...

Comparative Investigation of Prevalence and Antimicrobial Resistance of Salmonella between Pasture and Conventionally Reared Poultry

Avian Diseases Digest, 2007
The objective of this study was to compare Salmonella prevalence and antimicrobial resistance between pasture and conventional poultry farms. We collected the first Salmonella prevalence and antimicrobial resistance data on pasture poultry farms. Fecal droppings were collected from 31 farms from Wisconsin (nine farms from each production type) and the ...

A New Method of Poultry Litter Application to Perennial Pasture: Subsurface Banding

Soil Science Society of America Journal, 2008
Recently, incorporation of poultry litter by subsurface band application into pasture has been shown to reduce surface runoff transport of nutrients; however, data to evaluate the impact of this potential management strategy on forage production, forage nutrient concentrations, or the accumulation of soil nutrients after multiyear ...

Development of a Phosphorus Index for Pastures Fertilized with Poultry Litter—Factors Affecting Phosphorus Runoff

Journal of Environmental Quality, 2004
ABSTRACTCurrently, several state and federal agencies are proposing upper limits on soil test phosphorus (P), above which animal manures cannot be applied, based on the assumption that high P concentrations in runoff are due to high soil test P. Recent studies show that other factors are more indicative of P concentrations in runoff from areas where ...

Implications of Long‐Term Land Application of Poultry Litter on Tall Fescue Pastures

Journal of Production Agriculture, 1993
Alabama's poultry industry is most heavily concentrated in the Sand Mountain region of northern Alabama. Disposal of litter (manure and bedding material) generated from poultry production in the region is typically accomplished by land‐spreading onto tall fescue (Festuca arundinacea Schreb.) pastures.

Amino Compounds in Poultry Litter, Litter-Amended Pasture Soils and Grass Shoots

Pedosphere, 2014
Amino compounds (ACs), i.e., amino acids and amino sugars, are the major forms of organic nitrogen (N) in animal manure and soil. To increase our understanding on the effect of long-term poultry litter (PL) application on soil AC pools and turnover, in this study, we determined the contents of 21 ACs in 23 PL samples, 15 soil samples collected from 0 ...

Effect of poultry litter application and preferential flow on metal loss in pastures

Journal of Environmental Management
Large amounts of poultry litter, which is a mixture of manure and bedding material, are produced by the expanding poultry industry in the southeastern United States and are applied to pasture lands as an organic fertilizer. In addition to essential plant nutrients-nitrogen, phosphorus, and potassium (N-P-K)-poultry litter contains other nutrients and ...

Runoff of Estrogen Hormone 17β‐Estradiol from Poultry Litter Applied to Pasture

Journal of Environmental Quality, 1997
AbstractEnvironmental loading of hormones contained in poultry litter may cause or contribute to disruptions in the health and reproduction of animals. A runoff study was conducted to evaluate the hypothesis that poultry litter applied to pasture contributes the estrogen hormone 17β‐estradiol to runoff.
