Studied material was bird’s liver gathered from Ross 308 hybrid. In this way were established 3 experimental batches, differentiating by the age at which slaughtering was realised (F1= at 35 days; F2= at 40 days; F3= at 42 days). Quality determinations were realised on fresh product and aimed the content in water, dry matter, proteins, fats, ash, non-nitrogenous extractive substances and energetic value. Regarding protein content in analysed liver, batch F1 recorded a mean value higher with 0.03% face to batch F2 and with 0.15% face to batch F3. Regarding fat content, the highest mean value was obtained by batch F3, followed by batch F2 and batch F1; from statistical analysis of fat content was highlighted significant differences between batch F1 vs. batch F3 (P<0.05) and batch F2 vs. batch F3 (P<0.05). Calculus of energetic value presented the highest value at batch F3, higher with 1.95 kcal/100g face to batch F2 and with 1.31 kcal/100g face to batch F1; differences between those 3 batches being without statistical significance (P˃0.05). The obtained results showed that slaughtering age for Ross 308 hybrid didn’t have a significance influence on chemical composition of liver, with exception of fat content which became higher with bird’s aging.enCC BY-NC-SA 4.0https://creativecommons.org/licenses/by-nc-sa/4.0/birdsslaughteringliverchemical compositionArticle2821 - 6644
