Abstract

Forty second-cross growing ewe lambs (6 months old; 35.1 ± 1.9 kg BW) were used to study the effects of the nutritional value changes in terms of DVE and OEB (DVE - net truly absorbable intestinal protein; OEB - degraded protein balance) after dry roasting of whole lupin (Lupinus angustifolius) seeds (WLS) and whole faba (Vicia faba minor) beans (WFB) on the growth performance. Lambs were fed a fixed quantity of oat straw and alfalfa hay plus a daily supplement of either of the following: no legume seeds (CTRL), raw WLS, roasted WLS, raw WFB, or roasted WFB. Seeds were dry roasted at 150°C for 45 min. All diets were isonitrogenous (15.9% CP). In the supplemented diets, about 55% of protein w..
