Antinutritive factors

The presence of different antinutritive factors in the food- and feedstuffs plays an important role in the production and use of these materials. Some of these compounds have no direct toxic effect, but influences the utilization of other components of the nutrients.
The saponins represent an important group of the antinutritive factors. The presence of these compounds can be proved by biologic as well as by chemical methods. The physiological effects and the detailed description of the role of these antinutritive factors are summarized by Liener (1980) and T.Szabo (1982).
The saponins represent an important group of the antinutritive factors. The presence of these compounds can be proved by biologic (Jones, Elliot, 1969; Livingstone et al., 1977; Shany et al., 1970) as well as by chemical methods (Tencer et al., 1972; van Atta et al., 1961; Brawn et al., 1981). Since these compounds are surface active and act as detergents, we tried to find relationship between this character and the antinutritive effect.
