Extract

The use of exogenous enzymes extracted from batch microbes has expanded recently; and different enzymatic additives are being used to improve the nutritive value of monogastric diets. Most legume seeds contain measurable amounts of ? -galactosides, such as raffinose and stachyose (Kuo et al., 1988). These oligosacharides have been proved to pass undigested through the small intestine, and depress to some extent the digestibility of other nutrients (Gdala et al, 1997). Our aim was to assess the effect of adding a high dose ? -galactosidase to cereal-soybeanpea based diets on performance and digestive efficiency of growing pigs.

54 growing pigs (LW 43 ± 2 kg) were randomly allocated in eighteen pens, three animals each, and fed “ad libitum” a basal diet either supplemented with ? -galactosidase (Biogalactosidase, Quest; 400 ppm) or unsupplemented (nine pens/treatment).
