Abstract: A formulação com base no conceito de proteína ideal (PI) é mais eficiente quando são usados ingredientes alternativos ao milho (M) e ao farelo de soja (FS). Assim, o objetivo desse trabalho foi comparar formulações de dietas utilizando o conceito de PI, usando farinha de vísceras (FV) em substituição ao FS, em dietas de frangos de corte. Os tratamentos foram os seguintes: T1 = dieta com 22 % e 20% de proteína bruta (PB) nas fases inicial (FI) e de crescimento (FC) e 3200 kcal/kg de EM durante todo experimento;… Show more

“…Unlike the results observed in this experiment, Bellaver et al (2001) observed that diets with 5% of viscera and bone meal in substitution of soybean meal resulted in better broiler performance in the growing phase, but diets with 3% of viscera and bone meal did not affect performance until 21 days of age (Bellaver et al, 2005). Laboissiere (2008) verified that the best performance in the pre-starter phase was achieved with 9.0% of viscera and bone meal obtained from different processing systems (varying cooking temperature and moisture).…”

“…Laboissiere (2008) verified that the best performance in the pre-starter phase was achieved with 9.0% of viscera and bone meal obtained from different processing systems (varying cooking temperature and moisture). The inclusion of this ingredient resulted in 7% (Bellaver et al, 2001) to 14% (Girotto et al, 2002) cost reductions compared with soybean meal. By evaluating the digestibility data from the pre-starter assay (Table 4), one can observe that the levels of viscera and bone meal linearly increased (P<0.05) the digestibility coefficient of dry matter (Y = 71.816 + 0.487182X) and ether extract (Y = 78.3325 -0.8120488X).…”

“…This flour is relatively low cost and is a good source of nutrients when well processed (MOURA et al, 1994;PEREIRA et al, 1994;BELLAVER et al, 2001). However, the addition of some ingredients with high protein content may disturb the traceability of animal-derived flour in the feed of broilers as detected by stable isotopes.…”

“…Portanto, rações formuladas com base em aminoácidos digestíveis atenderiam mais eficientemente que aquelas formuladas com base na concentração total de aminoácidos (Rostagno et al, 1995;Wang & Parsons, 1998;Doulglas & Parsons, 1999;Araújo et al, 2004;Bellaver et al, 2001;Maiorka et al, 2004).…”
