Hansen / Para avaliar os efeitos do uso de probi?ticos sobre a metabolizabilidade da energia e digestibilidade de nutrientes em ra??es para su?nos, realizou-se um experimento com 32 su?nos, machos castrados, com peso de 31,2?4,7Kg, distribu?dos em delineamento experimental em blocos casualizados, em arranjo fatorial 2x2, sendo dois n?veis de energia metaboliz?vel (3200 e 3300 kcal/kg de energia metaboliz?vel), com ou sem adi??o de probi?tico, em 4 tratamentos e 8 repeti??es com um animal por unidade experimental. Os tratamentos foram assim constitu?dos: T1 - ra??o com 3200 kcal/kg de EM (3200 EM), T2 -ra??o T1 + 400 g/tonelada de probi?tico (3200 EM+P), T3 - ra??o com 3300 kcal/kg de EM (3300 EM) e T4 - ra??o T3 + 400 g/tonelada de probi?tico (3300 EM+P) e o per?odo experimental foram de 10 dias, sendo 5 dias para adapta??o dos su?nos ?s gaiolas e 5 dias para coleta de fezes e urina. Foram determinados os valores digest?veis da energia (ED), energia metaboliz?vel (EM), energia metaboliz?vel corrigida para balan?o de nitrog?nio (EMn), prote?na bruta (PB), extrato et?reo (EED), fibra bruta (FD), fibra em detergente neutro (FDND) e fibra em detergente ?cido (FDAD), mat?ria mineral (MMD), c?lcio (CaD) e f?sforo (PPD) das ra??es, para c?lculo dos coeficientes de metabolizabilidade e digestibilidade da energia e dos nutrientes. Maiores valores (P<0,05) de ED, EM e EMn, FDAD, EED e coeficiente de digestibilidade de extrato et?reo foram determinados na ra??o contendo 3300 EM+P. N?o houve diferen?a (P>0,05) entre as ra??es em rela??o aos coeficientes de digestibilidade e metabolizabilidade de energia, assim como para os valores de MMD, CaD, PPD, PD, FD e FDND. A inclus?o de probi?tico nas ra??es proporcionou incremento na energia das ra??es, devido ? melhoria na digestibilidade da FDA e EE. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Zootecnia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2014. / ABSTRACT To evaluate the effects of probiotics on the metabolizable energy and digestibility of nutrients in diets for pigs, we made an experiment with 32 pigs, barrows weighing 31.2 ? 4,7Kg distributed in experimental design randomized blocks in a 2x2 factorial arrangement, with two levels of metabolizable energy (3200 and 3300 kcal / kg metabolizable energy), with or without added probiotic in 4 treatments and 8 repetitions with an animal per experimental unit. Treatments were: T1 - diet with 3200 kcal / kg of ME (3200 ME), T2 - T1 diet + 400 g / ton probiotic (3200 ME + P), T3 - diet with 3300 kcal / kg of ME (3300 ME) and T4 - T3 diet + 400 g / ton probiotic (3300 ME + P) and the experimental period was 10 days, with 5 days for adaptation of pigs cages and 5 days for collection of faeces and urine. We evaluated the digestible of energy (DE), metabolizable energy (ME), metabolizable energy corrected for nitrogen (MEn), crude protein (CP), ether extract (EE), crude fiber (FD), neutral detergent fiber (DNDF) and acid detergent fiber (DADF), mineral matter (MMD), calcium (CaD) and phosphorus (PPD) to calculate the coefficients of digestibility and metabolizable energy and nutrients. Higher values were found ??(P <0.05) of ED, ME, MEn, DADF, EE and digestibility of ether extract in diets containing 3300 ME + P. There was no difference (P> 0.05) among diets in relation to digestibility and metabolizable energy, as well as the values ??of PD, FD, DNDF, MMD, CaD and PPD. The inclusion of probiotics in feed resulted in increased energy rations due to improved digestibility of DADF and EE.

In the first experiment, there was a metabolism assay for the determination of metabolizable energy and energy corrected apparent Metabolizable (EMAn), the traditional method of excreta collection using broilers fed with extruded semi-whole soybean (SSIE) at different temperatures. The treatments consisted of four levels of extrusion temperatures of the SSIE: 60% reference diet + 40% SSIE to 90 ? C; 60% reference diet + 40% SSIE to 100 ? C; 60% reference diet + 40% SSIE to 110 ? C and 60% + 40% reference diet SSIE to 120?C. In the second experiment it was determined the true total and digestible amino acids in 300 chickens from 16 to 21 days old. The treatments were: diet SSIE to 90 ? C; diet SSIE 100 ? C; SSIE diet at 110 and at 120 SSIE diet. The third experiment was conducted to verify the diets SSIE the 110C with four different nutritional matrixes: diet with commercial soybean meal (DFS); diet with nutritional matrix SSIE the 110C and corrected (DSC); diet with nutritional matrix SSIE to 110C determined by the analysis of online NIRS (DSN) and diet SSIE nutritional matrix as Brazilian Tables (DSTB). the growth performance, economic indices and carcass characteristics of broiler chickens submitted to the treatments were analyzed. The values of AME, AME, true digestible amino acid digestibility coefficients were significantly influenced by the extrusion temperature of the semi-integral soybean. The higher EMA (3720.09 kcal / kg) and AMEn (3424.99 kcal / kg) were obtained with the extrusion temperature of the semi-integral soybean approximately 105.6 ? C. The digestible amino acid values and true digestibility coefficients were influenced by the extrusion temperature of the semi-integral soybean. The best extrusion temperatures of the semi-integral soybean estimated for the real amino acid digestibility figures were 112.12?C to lysine, methionine 107.14?C, 106.11?C to cystine, arginine 111.77 112.25 and serine. The standardization of the SSIE extrusion temperature and the proper use of nutritional matrix of this ingredient in feed formulation positively influence the performance and economic index / Foram realizados tr?s experimentos nos setores de Nutri??o Animal e Pastagens do Instituto de Zootecnia da Universidade Federal Rural do Rio de Janeiro; Centro de Pesquisas Av?colas do Instituto Federal de Educa??o Ci?ncia e Tecnologia do Rio de Janeiro e Unidade de Produ??o de Ra??es de Bananal ? SP da Empresa Reginaves Industria e Comercio de Aves Ltda. No primeiro experimento, foi realizado um ensaio de metabolismo para a determina??o dos valores de energia metaboliz?vel e Energia Metaboliz?vel aparente corrigida (EMAn), pelo m?todo tradicional de coleta total de excretas utilizando frangos de corte alimentados com ra??es contendo soja semi-integral extrusada (SSIE) em diferentes temperaturas. Os tratamentos consistiram em quatro n?veis de temperaturas da SSIE : 60% dieta referencia + 40% SSIE a 90?C; 60% dieta referencia + 40% SSIE a 100?C; 60% dieta referencia + 40% SSIE a 110?C e 60% dieta referencia + 40% SSIE a 120?C. No segundo experimento foram determinados os amino?cidos totais e digest?veis verdadeiros em 300 frangos de 16 a 21 dias de idade. Os tratamentos estudados foram: dieta com SSIE a 90?C; dieta com SSIE a 100?C; dieta com SSIE a 110?C e dieta com SSIE a 120?C. O experimento tr?s foi realizado para verificar as dietas contendo SSIE a 110?C com quatro matrizes nutricionais diferentes: dieta com farelo de soja comercial (DFS); dieta com matriz nutricional da SSIE a 110?C e corrigida (DSC); dieta com matriz nutricional da SSIE a 110?C determina pela analise do NIRS online (DSN) e dieta com matriz nutricional da SSIE conforme Tabelas Brasileiras (DSTB). Foram analisados o desempenho zoot?cnico, ?ndices econ?micos e as caracter?sticas da carca?a dos frangos de corte submetidos aos tratamentos. Os valores de EMA, EMAn, amino?cidos digest?veis verdadeiros coeficientes de digestibilidade foram influenciados significativamente pelas temperaturas de extrus?o da soja semi-integral. Os maiores valores de EMA (3720,09 Kcal/ Kg) e de EMAn (3424,99 Kcal/Kg) foram obtidos com a temperatura de extrus?o da soja semi-integral de aproximadamente 105,6?C. Os valores de amino?cidos digest?veis e coeficientes de digestibilidade verdadeiros foram influenciados pelas temperaturas de extrus?o da soja semi-integral. As melhores temperaturas de extrus?o da soja semi-integral estimadas para os valores de digestibilidade de amino?cido verdadeiro foram de 112,12?C para lisina, 107,14?C para metionina, 106,11?C para cistina, 111,77 para arginina e 112,25 para serina. A padroniza??o da temperatura de extrus?o da SSIE e a utiliza??o correta da matriz nutricional deste ingrediente na formula??o de ra??es influenciam positivamente os ?ndices produtivos e econ?micos
