Extract

Principal among a number of antinutritive factors which have historically limited the use of rapeseed meal in pig diets are a group of compounds known as glucosinolates. These sulphur containing compounds may be goitrogenic and/or heptatoxic and additionally produce volatile and pungent hydrolysis products resulting in reduced palatability of diets. Newlyweaned pigs between 6 and 20kg do not in general perform well when fed diets containing appreciable amounts of rapeseed meal nor when fed diets with glucosinolate levels higher than 10 μmol/g diet. This is probably due to the sensitivity of young piglets to unpleasant tastes and to antinutritional components of feedstuffs. A study was designed to determine the response of newly weaned pigs to levels of dietary glucosinolate lower than 10 μmol/g resulting from a relatively low inclusion rate of rapeseed meal in the diet.
