Avaliação de inulina e probiótico para frangos de corte

Abstract: RESUMO. Objetivou-se com este trabalho avaliar o efeito de aditivos promotores de crescimento (prebiótico, probiótico e simbiótico) em substituição ao antibiótico sobre o desempenho e características de carcaça (cortes nobres, órgãos e gordura abdominal), em dietas para frangos de corte de um a 42 dias de idade. Foram utilizados 384 pintos de um dia de idade alojados sobre cama reutilizada. O delineamento experimental utilizado foi o inteiramente casualizado, com quatro tratamentos e seis repetições, sendo: PR… Show more

“…Faria et al (2009), in a study evaluating the use of probiotics as alternative to using antibiotics as growth promoters for broilers, also found no effect on feed intake during the period of 1-21 days. Silva et al (2011) obtained better result with antibiotic supplementation in the diets of broilers from 1 to 21 days of age.…”

“…The use of different growth promoter additives did not influence the results of feed conversion of chicks in the initial rearing phase in the studies conducted by Silva et al (2011), Rocha et al (2010), Faria et al (2009), Lorençon et al (2007, Takahashi et al (2005) and Pelicano et al (2004). However, Maiorka et al (2001), evaluating the effects of substitution of antibiotics by prebiotics, probiotics and synbiotics in diets for broilers in the period of 1-21 days of age, observed better feed conversion in poultry fed probiotics.…”

“…Comparatively, Rocha et al (2010), utilizing prebiotics, organic acids and probiotics in rations to hick broiler's obtained better breast yield in comparison to those who received ration without additives. Mozer da Silva et al (2011) did not find statistical meaning differences on cut yields to chicken from Cobb 500 lineage, supplemented with rations containing antibiotic and probiotic as a substitute. These authors concluded that the use of probiotic as growth promoter can be used as a substitute to antibiotics without compromising animal's performance.…”

“…Yasuda et al (2006) observaram que a utilização de inulina como ingrediente funcional melhora a absorção e a utilização de ferro presentes em dietas para leitões, aumentando as concentrações de hemoglobinas em até 28 % com a utilização de 4 % de inulina na dieta. Já em dietas de frangos de corte do primeiro aos 21 dias de idade, a suplementação de inulina proporcionou um aumento na colonização de bactérias benéfi cas no intestino grosso das aves, atuando como substrato no desenvolvimento, principalmente de Bifi dobacteria e Lactobacillus, microrganismos que favorecem o aproveitamento e absorção dos nutrientes da dieta, podendo assim ter melhorado o ganho de peso fi nal das aves (SILVA et al, 2011).…”
