Environmental assessment tools for the evaluation and improvement of European livestock production systems
January 1, 2005
Different types of assessment tools have been developed in Europe with the purpose of determining the environmental impact of various livestock production systems at farm level. The assessment tools...
Removal of pathogen and indicator microorganisms from liquid swine manure in multi-step biological and chemical treatment
January 1, 2005By Matias B. Vanotti
Concern has greatly increased about the potential for contamination of water, food, and air by pathogens present in manure. We evaluated pathogen reduction in liquid swine manure in a multi-stage...

Impact of early weaning and photoperiod manipulation on sow and piglet welfare
November 3, 2004By Janeen L. Salak-Johnson PhD
Animals adapt more readily to photoperiod cues than other environmental cues since photoperiod is more predictable and consistent over time. Previous work has shown limited (if any) affects of...
