“…Los efectos de los probióticos sobre las variables productivas de 1 a 7 días obtenidos en este trabajo fueron semejantes a los observados por Applet et al (7) que evaluaron probióticos en dietas de origen animal y vegetal en pollos de engorde, Bellaver et al (8) Los resultados obtenidos para la conversión alimentar puede ser debido a los inúmeros beneficios de los probióticos en la fase pre-inicial como el mejor equilibrio microbiano intestinal y acción moduladora (7). La mejor conversión de las aves alimentadas con ingredientes de origen animal, es debida a la alta densidad nutricional y a la disponibilidad de sus nutrientes para las aves.…”

RESUMENObjetivo. Evaluar el uso de probióticos en dietas con ingredientes de origen animal o vegetal sobre las variables productivas de pollos de engorde de 1 a 42 días de edad. Materiales y métodos. Fueron utilizados 1056 pollitos de un día de edad, machos de linaje Ross 308, distribuidos en un diseño experimental completamente al azar en un arreglo factorial 2X4 (dieta de origen animal o vegetal) y cuatro promotores (antibiótico, dos probióticos y un control negativo) con 6 repeticiones y 22 aves por unidad. Resultados. A los 7 días de edad hubo diferencia (p<0.05) en el consumo diario de alimento, peso y ganancia de peso y a los 14 días para peso, ganancia de peso y mortalidad entre las dietas. La conversión alimenticia de 1 a 7 días tuvo interacción (p<0.05) entre los tipos de dieta y los promotores. Hubo diferencia (p<0.05) para el peso y la ganancia de peso a los 14 días de edad entre los promotores. A los 21 días de edad la mortalidad presentó diferencia (p<0.05) para el tipo de dietas; el peso, ganancia de peso, consuno diario de alimento y conversión alimenticia presentaron diferencia para los promotores. A los 28, 35 y 42 días de edad la mortalidad y el índice de eficiencia productiva presentaron diferencia (p<0.05) entre el tipo de dietas. Conclusiones. El tipo de dieta y de promotor de crecimiento no afectan las variables productivas; sin embargo, la viabilidad mejora con las dietas de origen animal.

Evaluate the use of probiotics in diets whit ingredients of animal or vegetable origin in production variables of broilers from 1 to 42 days of age. Materials and Methods. Were used 1056 one-day-old chicks, male, of lineage Ross 308, divided in to an experimental randomized design in 2X4 factorial arrangement, two origin of diet (animal or vegetable) and four promoters (antibiotic, two probiotics and a negative control) whit 6 replicates and 22 birds per unit. Results. At 7 days old there was a difference (p<0.05) in daily food intake, weight and weight gain and 14 days for weight, weight gain and mortality among diets. The feed conversion of 1-7 days did interaction (p<0.05) between types of diet and promoters. There was a difference (p<0.05) for weight and weight gain at 14 days of age between promoters. At 21 days of age presented mortality difference (p<0.05) for the type of diets; weight, weight gain, daily feed together and feed conversion showed difference for 5337 developers. At 28, 35 and 42 days old mortality and productive efficiency index showed difference (p<0.05) between the types of diets. Conclusions. The type of diet and growth promoter did not affect production variables, however, the viability improvement animal diets.

“…Oliveira et al (2009), Appelt et al (2010), and Khosravi et al (2010) in experiments using a probiotic, a prebiotic, and an organic acid, respectively, also did not show any WG differences during the period of 1-42 days. Godoi et al (2008), Salazar et al (2008), and Meurer et al (2010) observed higher WG in broiler chickens fed prebiotic/symbiotic, organic acids, and probiotic, respectively, compared with controls, considering the period between one and 42 days of age.…”

KeywordsScanning electron microscopy, morphometrics, intestinal mucosa, intestinal wall.Submitted: May/2013 Approved: February/2014 ABStRACt This study aimed at evaluating the intestinal integrity, using light and scanning electron microscopy (SEM), and the performance of broiler chickens fed additives alternative to antimicrobials. A total of 1080 male chicks were distributed according to a completely randomized experimental design, with six treatments with six replicates of 30 birds each. The following treatments were evaluated: basal diet (control), basal diet supplemented with an antimicrobial, basal diet supplemented with a probiotic, basal diet supplemented with a prebiotic, basal diet with a symbiotic, and basal diet supplemented with organic acids. Weight gain, feed intake, feed conversion ratio and livability were recorded when broiler chickens were 10, 21, 35, and 42 days old. On day 42, 72 birds were individually weighed and sacrificed. In order to evaluate the morphometrics of the different intestinal wall layers, segments of the small intestine and the cecum were collected from two birds per replicate, and intestinal integrity (SEM) was evaluated in the same segments of two birds per treatment. During the starter period (1-21 days old), birds fed the alternative additives presented similar weight gain as those fed the antimicrobial product, but were not different from control birds. Feed conversion ratio of birds fed alternative additives was better than that of the control birds from one to 10 days of age, but not during the remaining rearing period, and was similar to the birds receiving the antimicrobial. The morphometric parameters of the different intestinal wall layers was not influenced by the treatments. During the total rearing period, the evaluated alternative additives did not improve intestinal integrity or broiler performance.

RESUMOAvaliou-se a alometria de órgãos digestórios e morfometria da mucosa intestinal, atividade de enzimas pancreáticas e perfil bioquímico sérico de frangos de corte de crescimento lento e rápido. O delineamento experimental utilizado foi de blocos ao acaso, com dois tratamentos (linhagens Isa Label e Cobb) e cinco repetições de 10 aves cada. Aos sete, 21 e 42 dias de idade, duas aves por repetição foram abatidas e o sangue e pâncreas foram coletados. As aves de crescimento lento apresentaram maior peso relativo órgãos digestórios, exceto para o peso do fígado e intestino delgado aos sete e 42 dias de idade, respectivamente. A linhagem Cobb apresentou maior altura de vilo no jejuno, íleo aos sete dias e duodeno aos 42 dias de idade. Os níveis séricos de Ca, P e triglicerídeos foram superiores nas aves Isa Label apenas aos 21 dias de idade. O peso relativo, atividade da amilase e lipase do pâncreas não diferiram entre as linhagens. Conclui-se que existem particularidades das linhagens Isa Label e Cobb quanto ao desenvolvimento dos órgãos do sistema digestório e parâmetros séricos bioquímicos. Palavras-chave:Enzimas digestivas, linhagens Isa Label e Cobb, mucosa intestinal, sistema digestório, soro Morphological and morphometric aspects of the digestive apparatus, serum biochemical measures and activity of pancreatic enzymes of slow-and fast-growing broilers ABSTRACTWe evaluated the biometry of digestive organs, morfometry of intestinal mucosa, pancreatic enzymes activity and serum biochemical parameter of slow-and fast-growing chicken genotypes. We used a randomized block experimental design with two treatments (Isa Label and Cobb strains) and five replicates with 10 broilers per experimental unit. In order to measure the evaluated parameters, two birds of each replicate were slaughtered at seven, 21 and 42 d of age. The Isa Label broilers presented relative weight of all components of the digestive tract, except for the weight of the liver and small intestine at seven and 42 days, respectively. Villus height was higher for Cobb than for Isa Label in the jejunum and ileum at seven days, and duodenum at 42 days of age. The relative weight, amylase and lipase activity of the pancreas did not differ between strains at different ages of assessment Relative weight and amylase and lipase activity of pancreas did not differ between strains at different ages. The serum Ca, P and triglyceride levels were higher in Isa Label birds only at 21 days of age. We concluded that Isa Label and Cobb strains present peculiarities regarding the development of the digestive system organs and the serum biochemical parameters.
