Lupin and rapeseed meals in poultry diets: Effect on broiler performance and sensory evaluation of carcasses

Abstract

1. The effect of including lupin meal (Lupinus angustifolius), with or without rapeseed meal, in computer-formulated, least-cost diets for broilers has, been determined.2. In the first experiment the diets contained 0, 8 (with and without supplementary methionine, lysine, or methionine and lysine) or 16% lupin meal: addition of the lupin meal required a concomitant addition of 5 % rapeseed meal (by computer selection).3. The diets were fed from 38 to 65 d and did not affect live-weight but the efficiency of food utilisation was significantly worse on the 16 % lupin, 5% rapeseed meal diet than it was on the control diet.4. The second experiment was designed as a 2 x 4 factorial to separate any effect due to rapeseed meal from that due to lupin meal, the treatments, which were applied from 1 to 62 d, being 0, 8, 16 and 24% lupin meal with and without 5 % rapeseed meal.5. Birds gained more rapidly in the second experiment on diets containing 16 or 24% lupin meal whereas live-weight was depressed when 5% rapeseed meal was included in the diets containing 0 or 8% lupin.6. The 16 and 24% lupin treatments also had added dietary fat from 6 to 9 weeks of age and this may have ameliorated the adverse effect of rapeseed meal.7. Up to 16% lupin meal and 5% rapeseed meal had no detectable effect on the colour, appearance, flavour or texture of roasted chicken meat when evaluated by a trained taste panel.

White Lupin as a Protein Source for Layers

“…Investigators have reported the effects of feeding white lupins to broilers (Yule and McBride, 1976;Zaviezo and McGinnis, 1980) and turkeys (Halvorson et al, 1983). These studies have shown that broilers and turkeys grow well on low levels of white lupins when supplemented with DL-methionine and Llysine.…”

Sweet whiteLupinus Albus(cv buttercup) as a feedstuff for layers

“…In the Republic of South Africa, where large amounts of fish meal and oil cakes are imported to meet the demand for protein, research on Lupinus albus in poultry diets is necessary to establish whether the climate, soil fertility or cultivars grown affect the nutritive value of the seeds. Yule & McBride (1976), Erikson & Elliot (1984), Olver (1987) and Watkins et al, (1988) found that up to 400 g/kg sweet lupins could be included effectively in broiler diets. In contrast Sentek et al (1979), Vogt et al (1979), Larbier (1980) and Watkins & Mirosh (1987) found that between 50 and 250 g/kg sweet lupins could be included in diets for laying hens without any effect on egg production.…”

Effect of sweet Lupins on duckling growth

“…The addition of 300 g lupins/kg to the maize-based diet and 150 g lupins/kg to a wheat-based diet also produced greater weight gain than in the respective control groups. Yule and McBride (1976) observed that broilers fed on diets containing up to 240 g/kg of ground lupin seed (Lupinus angustifolius) grew as rapidly as those fed on wheat-based diets, when the diets were balanced for amino acids and energy. Olver (1987) included sweet white lupins (L. albus) in broiler chick diets for up to 8 weeks.…”
