Swine Manure Applications for Soybean Production – Environmental and Pathological Implications
Environmental concerns regarding the application of nitrogen containing manure to soybean fields have been raised recently across the Corn Belt. The concern is that because soybeans are leguminous...

Adding Value to Swine Manure Through Accurate Prediction of Organic Nitrogen Availability
Swine slurry contains nitrogen primarily in organic and ammonium forms. Ammonium-N is immediately crop available following land application if not lost to volatilization which should be minimal if...

Manure-Phosphorus in Soil: Detection and Mobility of Phytate
Annual swine effluent application in western Oklahoma for 11 consecutive years did not lead to significant accumulation of soil phosphorus. Similar trend was shown in a century-old field experiment...

Influence of corn co-products on air emissions and nutrient excretionsfrom grow-finish swine
Corn co-products are an increasingly important alternative to corn in swine diets. While there has been some research to evaluate how these co-products affect pig performance, the effect on air...

Evaluation of the effects of diet formulation method and inclusion of DDGS and phytase on manure phosphorus excretion of grow-finish pigs and on the concentration and forms of P in manure amended soil
• Formulating diets with phytase reduces the concentration of total P in the manure compared to a conventional diet by as much as 30%. • Using DDGS in the diet results in no significant...

Free fatty acids and sterols in swine manure
Free fatty acids and sterols were assessed in fresh manure and anaerobic lagoon sludge from swine production facilities in North Carolina. Eight free fatty acids and five sterols were identified and...

Disposal of Swine Lagoon Sludge with Nutrient Recovery
Gasification offers many advantages for processing undesirable waste materials. Tests on gasifier emissions reveal very low levels of NOx, SOx and volatile organic carbons in the flue gas, well...

Disposal of Swine Lagoon Sludge with Nutrient Recovery
Sludge accumulation in lagoons reduces their treatment efficiency over time and, ultimately, may cause the decommissioning of the lagoon. Gasification is an ideal technology for sludge disposal since...

Utilization of Crystalline Amino Acids by the Gut in Growing Pigs
Conventional diets containing corn and soybean meal fed to growing pigs can be reduced in protein when a portion of the protein can be replaced by crystalline amino acids. These amino acids allow the...

Establishing Effects of application of Swine Manure on Crop Leaf Damage to Growing Crops
The use of irrigation systems to apply swine effluent and liquids from storage and holding ponds is a popular application method due to the labor savings, large volumes of liquid, and when applied...
