Influence of thermally treated and untreated lupin meal on the indicators of performance and health condition of broilers

A total of 161 sexed broiler chickens of Ross 308 type were fed feeding mixtures containing thermally treated or untreated lupin meal. The group of cocks (LNM) and hens (LNF) fed a diet containing 10% untreated lupin meal reached a higher mean weight in comparison with the groups consuming a diet with the content of 10% meal treated by heat (LTM and LTF). The cocks in the LNM group reached a higher live weight (2,680.26 g) on day 42 compared with the cocks in the LTM group (2,591.28 g). A significantly higher weight was observed in LNF hens (2,357.25 g) than in LTF hens (2,241.22 g) on day 42. Blood was taken from vena basilica on day 42. The results of haematological and biochemical tests ranged within physiological values. Our results suggest that thermally untreated lupin meal is more suitable in the nutrition of broiler chickens than the thermally treated one.
