Suplementação de extrato de <i>Lafoensia pacari</i> na ração de poedeiras semipesadas

Objetivou-se avaliar a suplementação do extrato de Lafoensia pacari padronizado em taninos na ração de poedeiras sobre o desempenho, a qualidade interna e externa de ovos e metabolizabilidade dos nutrientes da ração. Utilizaram-se 168 poedeiras Isa Brown com 24 semanas de idade, peso médio 2,6 kg e taxa de postura média 87% durante quatro períodos de 28 dias cada. Os tratamentos constituíram de rações com antibiótico melhorador de desempenho Halquinol, prebiótico Mananoligossacarídeo (MOS) e três níveis de extrato de pacari - 1.000, 2.000 e 3.000 mg kg^-1 de ração. O delineamento experimental foi inteiramente casualizado com seis tratamentos e sete repetições com quatro aves cada. O extrato de pacari padronizado em teor de taninos apresentou porcentagem de albúmen e peso do ovo semelhante ao antibiótico (p < 0,04). A suplementação com o extrato melhorou a qualidade da casca, verificada pela gravidade específica (p < 0,03) e promoveu metabolizabilidade do extrato etéreo semelhante ao antibiótico e MOS (p < 0,04), sendo indicado como aditivo fitogênico.
