In order to evaluate the nutritive value of imported lupin seed from Western Australia on the performance of the chicken, proximate and amino acid composition and total alkaloid content of lupin seed were analyzed. For 5 week feeding trial, one hundred sixty hatched male broiler chickens were randomly distributed to 16 group of 10 birds each. Four groups were placed on one of the following four experimental diets; Soybean Control diet, Unheated Lupin diet, Heated Lupin (autoclaved at 135℃ for 30 min) diet and Methionine supplemented Unheated Lupin (0.063 % of additional D,L - methionine) diet. Lupin diets included lupin seeds at the level of 20% of diets. AV experimental diets were least-cost formulated by computer to contain isocalorie and isonitrogen, and to meet essential nutritients requirements recommended by NRC. Results of the feeding trial showed that birds fed Soybean Control diet gained significantly more weight than those fed either Unheated or Heated Lupin diet (p$lt;0.05). Birds fed Lupin + Methionine diet gained less than the control until 3 weeks of age but gained more during 4th and 5th week. There was no significant differences in feed intake among treatments but feed efficiency was improved by methionine supplementation. Heat treatment slightly improved weight gain but failed to show any significant improvement in overall performance. The availabilities of dry matter and crude fat of Soybean Control were significantly (p$lt;0.01) higher than those of other treatments.

In order to determine the optimum level of Australian Lupin seed in the broiler chicken diet, metabolizable energy values were determined and a feeding trial was conducted. Metabolizable energy values determined by 28wk old roosters were 2,171 Kcal AME, 2,144 Kcal AMEn, 2,527 Kcal THE and 2,512 Kcal TMEn per ㎏ dry matter of Bound seed. In a 5 week feeding trial, 144 hatched broiler chickens were divided into 16 groups of 9 birds each. Four groups were randomly placed on one of the following 4 experimental diets; Soybean control, Lupin 7%, Lupin 14% and Lupin 21%. The result of feeding trial showed no significant differences between treatments in the weight gain, feed intake and feed efficiencies. The availabilities of dry matter, however, were significantly (P$lt;0.01) lower for those of higher Lupin seed diets (14%, 21%) than the control. The influence of the low dry matter digestibility may be counteracted by higher levels of animal fat in the formulas of high Lupin seed diets.
