Surface Runoff Quality in Grasslands Fertilized with Broiler Litter
Surface application of broiler litter to grasslands can increase concentrations of ammonium (NH₄+-N) and dissolved reactive phosphorus (DRP) in surface runoff. It is not known, however, for how long after broiler litter applications that NH₄+-N and DRP concentrations remain elevated. Five 0.75-ha, …

Fermentation, digestibility and palatability of ensiled broiler litter and corn forage
… the fermentation and nutritive value of ensiled broiler litter and corn forage. The non-processed broiler litter, containing a wood shaving base, contained 82.9% DM, 26.8% crude protein, 23.0% crude fiber and 16.7% ash. Corn forage was harvested at two stages of maturity, corresponding to 26 and …

Utilization of phosphorus and other minerals from broiler litter and swine waste
… and certain other minerals from swine waste and broiler litter. The effect of source and level of P on rumen cellulytic bacterial populations was also determined. Animals were fed a low P basal diet until serum inorganic P averaged 5.5 mg/dl, then randomly assigned to the following diets: low P …

Residual Nutrient Removal by a Winter Cover Crop From Broiler Litter Amended Soils
… build-up in pasture and cropland as a result of broiler litter application. Studies were conducted at Western Kentucky University using sorghum sudangrass (Sorghum bicolor (L.) Moench) as a forage to possibly remove excess nutrients. This project led to a consideration of using a cover crop to …

Reducing Ammonia Volatilization and Escherichia coli from Broiler Litter Using Multiple Applications of Sodium Bisulfate
… emissions from animal manure, such as poultry litter, can cause air quality problems. These emissions also result in excessive nitrogen (N) loading into aquatic environments which can lead to water quality problems where N is the limiting nutrient for eutrophication, such as the Chesapeake Bay. …

Nitrogen values of liquid dairy manure and dry broiler litter as affected by preservation treatment
Five liquid dairy manures and five dry broiler litters were tested in the laboratory to determine the effects of four preservation techniques on the forms and concentrations of nitrogen. 300 ml samples of fresh manure from five Virginia dairy and five poultry farms were analyzed for total Kjeldahl, …

Solubility, degradability and utilization by ruminants of broiler litter processed by ensiling, deepstacking and composting
… supplementing ensiled, deepstacked and composted broiler litter as N sources with soybean meal. Sheep were fed isonitrogenous (10.3% CP) and isocaloric (56% TDN) corn cob-based diets. Apparent digestibility of CP was somewhat depressed by feeding deepstacked and composted litters; however, N …

Effect of feeding high levels of broiler litter on mineral metabolism and health of beef cows
… disturbances in beef cows fed high levels of broiler litter. Therefore, an experiment was conducted to evaluate mineral metabolism of beef cows fed different levels of broiler litter. Sixty Angus-Hereford crossbred cows ranging in age from 3 to 12 yr were blocked by age, BW, and stage of …

The effect of processing method of broiler litter on pasteurization, nitrogen loss and nitrogen utilization by sheep
Various broiler litter processing methods were evaluated. Treatments effective for litter pasteurization were dry heating at a depth of 0.63 cm for 20 min; autoclaving for 10 min. or longer; dry heating following the addition of 1 to 4 g of paraformaldehyde (PFA) per 100 g of litter at depths of …

Fermentation, utilization and palatability of broiler litter ensiled at different moisture levels and with high moisture corn grain
The feasibility of ensiling broiler litter alone, with added water or with high moisture corn grain was evaluated. Wood shaving based broiler litter was ensiled in small laboratory silos (about 4 liters) at moisture levels of 15.6 (no water added), 20, 30, 40 and 50%. Maximum fermentation was …

Long-term Effects of Broiler Litter Application Rate on Runoff, Leaching, and Soil Respiration from a Captina Silt Loam
<p>Producers in regions with intense broiler (<em>Gallus gallus<em>) production take advantage of the plant nutrients contained in broiler litter (BL) to enhance yields of forage grasses. However, application of BL to pasture lands in karst regions, like the Ozark Highlands, can potentially reduce …

Influence of molybdenum and sulfate supplementation and withdrawal of diets containing high copper broiler litter on tissue copper levels
… three diets: basal (6 ewes); 50% basal and 50% broiler litter (24 ewes), and 50% basal and 50% broiler litter with the addition of 25 ppm molybdenum (Mo) and 5 g sulfate/kg feed. The 24 litter fed ewes were allotted to withdrawal times of 0-, 30-, 60- and 120-d. The control (basal) diet …

Utilization of corn silage grown by conventional and sustainable methods fed with different nitrogen supplements
… and 4) sustainable corn silage supplemented with broiler litter. Apparent DM digestibilities were 65.9, 69.3, 63.8, 66.2%, for the respective diets. Apparent digestibilities of NDF, ADF, and cellulose were lower (P < .05) for the urea-supplemented diets than the SBM and broiler litter supplemented …

Processing and nutritional value of poultry litter and slaughter house by-product
… to study: 1) the different methods of processing broiler litter for use as a feed ingredient; and 2) preservation, fermentation and nutrient utilization of rumen contents and blood. Broiler litter was deep stacked in 1.2 x 1.2 x 1.2 m bins at 15, 25 and 35% moisture, and ensiled at 40% moisture, …

Mineral element profiles of animal wastes and edible tissues from cattle fed animal wastes
… animal wastes and tissues from cattle fed broiler litter or cattle waste. Heifers fed 30% broiler litter ensiled with corn forage performed as well as heifers fed corn silage and soybean meal but performance tended to be lower than for heifers fed corn-litter silage and soybean meal in a …

Rapid Phytate Quantification in Manures and Runoff Sediments using HPIC
… quantification of phytate in dairy manure and broiler litter when measured by high performance ion chromatography (HPIC). In this study dairy manure and broiler litter samples were spiked with Al, Fe, and phytate. Samples were alkaline extracted, acidified,cleaned up and filtered, and then …

Utilization by ruminants of poor quality hay supplemented with different nitrogen and carbohydrate sources
… in lick-tank, 4) mixture of deep-stacked broiler litter and ground corn grain and 5) soybean meal. Preliminary observations showed that the liquid supplement injected into bales was poorly distributed. Highest daily weight gains were for the animals supplemented with urea-molasses …

Nitrogen Rate and Source Effects on Biomass Yield of Teff Grown for Livestock Feed in the Mid-Atlantic Region
… application of either ammonium nitrate (AN) or broiler litter (BL) at seeding. The experimental design was a randomized complete block with a two-factor factorial treatment design (N rate and source) and four replications. Biomass yield typically peaked at the 90 kg N ha-1 rate, but rarely …

Three essays on environmental issues associated with broiler production in Louisiana
… increasing trends of integrated and concentrated broiler production results in a serious threat to environment through excessive litter production and lack of its proper disposal. Production concentration in limited area is a major source of surface as well as ground water pollution. Nonpoint …
