The Nutritive Value For Growing Pigs of Single Cell Protein (Saccharomyces Cerevisiae) Produced from Sulphite Spent Liquor

Fórverdien til griser i vekst av encelleprotein (Saccharomyces cerevisiae) produsert fra sulfittlut

Abstract

The effects on growing pigs of substituting 4.5 and 9 % of soy bean meal with a corresponding amount of single cell protein produced from sulphite spent liquor in a diet based on cereals and fish meal have been studied. The concentration of lignosulphonic acids in the single cell protein product was found to be 0.6 % ± 0.2 % (m. ± s). No differences in the weight gain, feed conversion ratio or fat thickness of the pigs, as compared with the controls, were observed when fed single cell protein-containing diets from about 29 to 80 kg in the course of 11 weeks. Nor were any effects found on addition of 0.15 % of methionine to the diets.

Sammendrag

En har studert virkningen på griser i vekst av å bytte ut 4,5 og 9 % soyamel med encelleprotein produsert fra sulfittlut i en diett, basert på cerealier og fiskemel. Innholdet av ligninsulfonsyrer i encelleproteinet ble funnet å være 0,6 % ± 0,2 % (middel ± s). Det ble ikke funnet noen virkning på tilvekst, fórutnyttelsesgrad eller fetttykkelse hos grisene i forhold til kontrollene når de ble foret opp fra ca. 29 til 80 kg i løpet av 11 uker. En fant heller ingen virkning av å tilsette 0,15 % metionin til dietten.
