Effect of Protein Content of the Diet on Nitrogen Excretion by Pigs
Posted in: Environment by admin on January 1, 1992 | No Comments
Reduction from 15 to 20% of N excretion was realized by lowering the crude protein content of the diet of 10% during the growing period and 7% during the finishing period.

Development of a Calculation Model for Predicting the Amount of N Excreted by the Pig: Effect of Feeding, Physiological Stage and Performance
Posted in: Environment by admin on | No Comments
The model showed that interesting effect when the performances of the production system are improved. More piglets produced per sows and also improvement in the feed conversion ratio have an effect on the nitrogen output of the system. the average daily gain did not have a direct and important effect.

Minimizing Potential Human Health Risks Involved in Hog Farming
Posted in: Environment by admin on | No Comments
Swine confinement buildings often do not have appropriate technologies to reduce the level of respirable indoor environmental contamination. A major cause of this environmental contamination is dust from feed, faecal material, molds, etc. Other causes include endotoxins and gases, such as ammonia, hydrogen sulfide, methane, carbon dioxide and carbon monoxide. The goal is to first control these pollutants at the source, second, eliminate them once they are in the air and finally wearing dust masks or other such equipment to further reduce an individuala
Estimates of nitrous oxide emissions from agricultural fields over 28 months
Posted in: Environment by admin on | No Comments
Field studies conducted throughout the calendar year are needed to improve flux estimates for the greenhouse gas nitrous oxide (N2O). In this study, we report monthly N2O emissions
measured using micrometeorological techniques and a Tunable Diode Laser Trace Gas Analyzer (TDLTGA). Nitrous oxide fluxes were measured at the Elora Research Station (20 km north of Guelph, Ontario) from July to November 1992, and from March 1993 to February 1995, giving a total of 2445 daily averages obtained during the full length of the experiment. The soil at the experimental site was a Conestogo silt loam (Gleyed melanic brunisol). Several fields were monitored including fallow,
manured fallow, Kentucky bluegrass, alfalfa, barley, canola, soybeans and corn plots. Spring thaw emissions from fallow or ploughed plots measured from March to April ranged from 1.5 to 4.3 kg N haa
