Extract

In vitro methods which can be used to predict the nutritive value of feedstuflfs for livestock are attractive in terms of both speed and economy. The in vitro pressure transducer technique (PTT) whereby the gas evolved during the in vitro fermentation of feedstuffs in rumen fluid is quantified by a pressure transducer, has been used to predict the nutritive value of ruminant feedstuffs. Here the potential for the PTT in predicting the digestible energy contents of eight feedstuffs varying in non-starch polysaccharide (NSP) content fed to growing pigs, was investigated.
