Abstract

CITATION: Brand, T. S., et al. 2018. Use of sweet lupin, canola oilcake and full-fat canola as alternatives to soybean oilcake in diets for broilers. South African Journal of Animal Science, 48(3):553-562, doi:10.4314/sajas.v48i3.16.

Highlights

Protein sources are likely to become progressively more limiting and costly, owing to competition between feed ingredients for humans and monogastric animals (Florou-Paneri et al, 2014)
Lupin is relatively high in crude protein (CP) (35.5%) (Brand et al, 1995), problems could arise with its use in broiler diets because of the existence of anti-nutritional factors
These results suggest that the levels of alkaloids in the sweet lupin did not affect feed intake

Summary

Introduction

Protein sources are likely to become progressively more limiting and costly, owing to competition between feed ingredients for humans and monogastric animals (Florou-Paneri et al, 2014). Exploitation of the nutritional potential of all possible protein sources is necessary. Sweet lupin (Lupinus albus and Lupinus angustifolius) is cultivated as a key legume crop in the winter rainfall region of South Africa, where it is estimated that 10 000 tons are produced annually. Lupin is relatively high in crude protein (CP) (35.5%) (Brand et al, 1995), problems could arise with its use in broiler diets because of the existence of anti-nutritional factors. Lupin may have undesirable levels of alkaloids (Erickson, 1985) and 〈-galactosides (90.0 g/kg) (Bourdon et al, 1987). Lupin has low starch content (0.3–0.5%) (Cerning-Beroad & Fillatre, 1976) and a high level of non-starch polysaccharides (NSP) (50.2%) (Chesson, 1990), about 15.0% of which is soluble (Annison et al, 1996)
