Evaluation of commercial manure additives to control odors from swine barns
January 1, 1997
A protocol was developed and tested to evaluate commercial manure additives in pig finishing barns. The ammonia and manure were analysed for fertilizer value. Air samples, collected at regular...

Dust concentrations and particle size distribution in an enclosed swine nursery
January 1, 1997
Dust levels in a mechanically ventilated swine nursery were measured for 13 sampling days over a six-week period during warm weather conditions. Mean daily room air temperature and relative humidity...
Soil microbial populations, community composition, and activity as affected by repeated applications of hog and cattle manure in eastern Saskatchewan
January 1, 1997By J. R. de Freitas
A field site near Humboldt, Saskatchewan, was annually treated with hog or cattle manure and cropped to canola, spring wheat, barley, and canola from 1997 to 2000. During each growing season, soil...
An on-farm swine waste treatment system for odor control, byproduct recovery and treated wastewater reuse in Hawaii
January 1, 1997
A prototype of a pig waste treatment system for a 240-270 pig operation was investigated for its potential of odour control, byproduct utilization and treated wastewater reuse. The high solid portion...
Effect of supplemental phytase and ideal dietary amino acid ratios in covered and hulless-barley-based diets on pig performance and excretion of phosphorus and nitrogen in manure
January 1, 1997By R. R. Grandhi
A total of 144 (72 barrows + 72 gilts) crossbred pigs were used to determine the effect of feeding supplemental phytase and ideal dietary amino acid ratios in covered barley (CB) or hulless barley...
Characterization of volatile organic emissions and wastes from a swine production facility
January 1, 1997
Analytical methods for monitoring the volatile organic compound (VOC) emissions, for defining atmospheric transport coefficients, and for monitoring solution phase chemistry have been developed to...
Swine wastewater treatment by media filtration
January 1, 1997By A. A. Szogi
A media filter was constructed to treat swine wastewater after anaerobic lagoon treatment. The media filter consisted of a tank (1.5-m-diameter x 0.6-m-height) filled with marl gravel. The marl...
