Phytogenic additive as an alternative to growth promoters in broiler chickens Aditivo fitogênico como alternativa aos promotores de crescimento em frangos de corte

Abstract

This study evaluated a phytogenic feed additive for broiler chickens. A total of 1,632 broiler chicks were distributed into four treatments: negative control (without growth promoter); positive control (avilamycine, 10ppm + colistin, 15ppm); and two alternative treatments with 150ppm of phytogenic additive, one with a reduced Ca and P levels diet (PA-R1) and the other with lower energy, and amino acids, besides Ca and P (PA-R2). The trial was conducted with 12 replicates, each consisted of a pen with 34 birds. The alternative diets showed body weight intermediate to the two controls at 42 days, with no significant (P>0.05) treatment effect on feed conversion ratio. No treatment differences (P>0.05) on carcass yield and composition was observed. There was a tendency of abdominal fat lipids saturation, when the phytogenic additive was used, as possible consequence of a decreased level of soybean oil in the diets. A difference (PO objetivo neste estudo foi avaliar a utilização de um aditivo fitogênico na dieta de frangos de corte. Um total de 1632 aves foram distribuídas em quatro tratamentos: controle negativo (sem antibiótico promotor de crescimento; controle positivo (com avilamicina, 100ppm + colistina, 15ppm), e dois tratamentos alternativos com 150ppm do aditivo fitogênico, um com níveis de Ca e P reduzidos (PA-R1) e outro também com menores níveis de energia e aminoácidos (PA-R2). O experimento foi conduzido com 12 repetições, cada uma delas com 34 aves. As aves submetidas às dietas alternativas apresentaram peso corporal médio, intermediário aos tratamentos de controle, aos 42 dias de idade, não se observando efeito significativo (P>0,05) na conversão alimentar. Nenhuma diferença (P>0,05) foi observada no rendimento e na composição centesimal da carcaça. Com adição do aditivo fitogênico, verificou-se aumento da saturação dos lipídios da gordura abdominal, possivelmente, devido à menor inclusão de óleo de soja em tais dietas. Houve diferença significativa (P<0,001) no consumo de ingredientes entre os tratamentos. O conjunto dos dados mostrou que a utilização do aditivo fitogênico possibilita a redução do custo da ração necessária para produzir um frango ou uma tonelada de peso vivo.
