The nutritional value of four cultivars of Lupinus angustifolius L. seeds was investigated. The
experiment was conducted on 50 male 16-day-old Ross 308 chickens. The birds were
randomly allocated to five dietary treatments (10 replications each). Digestibility was
calculated using the difference method. The basal diet and four diets composed of ground
lupin seeds (cv. Sonet, Boruta, Graf or Neptun) and the basal diet at a proportion of 25: 75
(w/w) were prepared. The birds were fed the diets starting from day 16; on days 19 and 20 of …

1. Two experiments were conducted to evaluate the nutritional value of three cultivars
(Wallan, Tanjil and Borre) of narrow-leafed lupin (Lupinus angustifolius) for broilers. 2. In
Experiment 1, the apparent metabolisable energy (AME) and the apparent ileal amino acid
digestibility of the three cultivars were determined. The cultivar effects were not significant for
AME and apparent ileal amino acid digestibility coefficients. In general, amino acids in
narrow-leafed lupin were well digested, with the notable exception of methionine. Among …
