“…Segundo Menten (2001), é de fundamental a existência de um desafio sanitário de campo suficiente para que os aditivos promotores de crescimento possam produzir efeitos significativos sobre o desempenho de aves e suínos. Pelícia et al (2010) não encontraram efeito da inclusão de 0,04% de nucleotídeos no desempenho de frangos de corte. Por outro lado, Bruno (2009) encontrou efeito positivo no desempenho de frangos de corte utilizando 0,05% de nucleotídeos na dieta no periodo de 1 a 21 dias de idade.…”

RESUMOObjetivou-se avaliar o efeito da suplementação com glutamina e nucleotídeos na dieta sobre o desempenho e morfologia da mucosa intestinal de frangos de corte criados no sistema alternativo. Foram utilizados 600 pintos de corte machos distribuídos em delineamento em blocos casualizados, no esquema fatorial 3x2 (três níveis de glutamina: 0,0; 0,5 e 1,0% e dois níveis de nucleotídeos purificados na dieta: 0,0 e 0,04%), totalizando 6 tratamentos, com 4 repetições de 25 aves cada. Foram obtidos os dados de desempenho (peso corporal, ganho de peso, consumo de ração, conversão alimentar e mortalidade) aos 7, 21 e 42 dias de idade. Ao final do experimento foram abatidas 4 aves/tratamento para avaliação do peso de órgãos e da morfologia intestinal. A adição de 1% na dieta melhorou o ganho de peso, consumo de raçao e conversão alimentar na primeira semana de idade. Não sendo encontrados resultados positivos nos períodos de 21 e 42 dias de idade. A suplementação de glutamina e nucleotídeos em dietas de frangos de corte criados no sistema alternativo não influencia o desempenho e a morfologia intestinal, a inclusão de 1,0% de glutamina no período de 1 a 21 dias de idade, favorece o desempenho das aves. SUMMARYThe experiment was conducted to evaluate the effect of supplementing glutamine and nucleotides on growth performance and development intestinal morphology in broiler chicks. In the trial, 600 male broiler chicks distributed in randomized blocks in a 3x2 factorial arrangement (consisting of a uniform basal diet supplemented with: 0.0, 0.5 or 1.0% glutamine, and 0.0 or 0.04% nucleotides), for a total of 6 treatments with 25 birds each. Means of performance (weight, weight gain, feed intake, feed conversion and mortality) were obtained 7, 21 and 42 days of age. At the end of the experiment 4 broilers per treatment were used to determine organs weight and development intestinal morphology. Glutamine supplementation (1%) improved the body weight, feed intake and feed conversion in the first week. Glutamine and nucleotides supplementation did not affect performance in broiler chicks in the period one to 21 and one to 42 days of age. In conclusion, it was demonstrated that feeding 1.0% glutamine improved growth performance of broiler birds at 21 days of age. INTRODUÇÃONo Brasil, como em outros países, temse observado crescente preocupação dos consumidores com a origem e qualidade dos produtos, exigindo alimentos saudáveis e ausência de resíduos.

“…These results supported by Owens and McCracken (2006) who found no significant difference in feed: gain value in panned birds over all experimental period. Also, Pelícia et al (2010) who noted no differences in feed conversion ratio between nucleotide supplemented and negative control group. On the other hand, Masey O'Neill et al (2014) who verified that the addition of yeast extract of Saccharomyces cerevisiae, containing high nucleotides, to broiler pre starter diets led to beneficial effects on the feed conversion ratio of the birds.…”

The present experiment was designed to investigate the effect of nucleotide as an immunostimulant for broiler chicks in terms of chick performance and economic efficiency. A total number of two hundred forty-one-day-old broiler chicks (Ross 308) were randomly distributed into four different treatment groups (A, B, C and D), of three replicates (20 chicks / replicate). The chicks in control group (A) were fed negative control diet, group B were fed diet containing (Nucleoforce ®) (0.025%) in first 10 days of age, group B were fed diet containing (Nucleoforce ®) (0.025%) in first 25 days of age. While group D was fed diet containing Nucleoforce ® (0.025%) from zero day till slaughtering. Results showed that, groups fed diet supplemented with Nucleoforce ® recorded improvements in live body weight, body weight gain and relative growth rate with no significant difference in feed intake and feed conversion index than the control group. Economic efficiency showed non-significant difference between control group and other groups but group (D) recorded high value 0.94 more than control group (A) 0.84. It was concluded that, inclusion of nucleotide 0.025% in broiler diets had a positive role in improvement of final body weight, body weight gain, feed conversion ratio and economic efficiency.

The aim of this experiment was to evaluate the effect of sources of trophic action (glutamine alone, glutamine associated with glutamic acid and yeast) associated with vaccination against coccidiosis on the performance and morphometry of the small intestine of broilers. In the trial, 1,200 broiler chicks were distributed according to a completely randomized design with a 3 x 2 + 2 (trophic action x vaccination or not + control -free trophic factor) factorial arrangement, with five replicates of 30 birds each. Vaccination negatively affected performance parameters and the morphometry of the intestinal mucosa, but at the end of the experimental period, among the broilers vaccinated against coccidiosis, the group fed glutamine presented better recovery from epithelial losses of the intestinal mucosa compared with the control groups. Therefore, the dietary supplementation with the evaluated sources of trophic action could be a strategy to enhance the development of broilers submitted to vaccine stress, also considering the economic viability of the productive segment.
