In addressing the topic of “The Relationship of Animal Leanness to Meat Tenderness,” I think it is extremely important to establish how much variability in tenderness exists and the extent to which the lack of tenderness is a problem. In addition, it is important to establish a definition or description of “animal leanness.” Carcasses may be lean because animals were fed beta-agonists, injected...

Though bad odour has always been associated with animal production, it did not attract much research attention until in many countries the odour production and emission from intensified animal production caused serious nuisance and was implicated in the health problems of individuals living near animal farms. Odour from pig production facilities is generated by the microbial conversion of feed ...

RE cultures infected with a fixed rabies virus were studied. The virus can propagate itself in these cells for an indefinite period of time without interfering with cell growth. The present study characterizes this truly endosymbiotic relationship. Virus-specific antigen was detected in the cytoplasm of each cell by fluorescein-labeled antirabies serum but only 4 to 5 per cent of the cells rele...

BACKGROUND Invasions of natural communities by non-indigenous species are currently rated as one of the most important global-scale threats to biodiversity. Biodiversity itself is known to reduce invasions and increase stability. Disturbances by ecosystem engineers affect the distribution, establishment, and abundance of species but this has been ignored in studies on diversity-invasibility rel...
