Feed intake of ruminants is controlled either by the limits of physical capacity of the body or a multiplicity of coordinated physiological pathways which are largely energized by metabolites of food and neural feedback systems. Itwas found that physical and physiological factors regulating feed intake changed quantitatively with increasing digestibility of food. At low digestibility they were:...

When more than a million broiler chickens suddenly and unexpectedly died in the eastern and midwestern parts of the United States in late 1957; the first dioxin crisis record was set [1]. It took nearly 10 years of investigation to pinpoint 1,2,3,7,8,9hexachlorodibenzo-p-dioxin as the hydropericardiumproducing factor, the responsive agent for the so-called chick edema disease [2].
