Abstract in Portuguese
O objetivo deste trabalho foi avaliar a adição de diferentes níveis de levedura (Saccharomyces cerevisiae) inativa e desidratada às rações, associados ao plasma sangüíneo e ao ácido glutâmico, sobre o desempenho e morfologia intestinal de leitões na fase inicial. Para tanto, foram realizados dois experimentos, cada um com três tratamentos de quatro repetição com 22 animais em fase de creche (21 à 59 dias), totalizando 264 leitões por experimento. Os animais foram distribuídos em delineamento em blocos casualizados nos dois experimentos. Ambos foram divididos em quatro fases experimentais correspondentes as trocas das dietas: pré - inicial 1(21-28), pré - inicial 2 (29-35), pré - inicial 3 (36-42). O experimento 1 teve os seguintes tratamentos: Ração Pré Inicial 1 - A - 5% de levedura inativa, 4% de plasma, 1% de ácido glutâmico; B - 3% de levedura inativa, 2% de levedura hidrolisada, 4% de plasma e 1% de ácido glutâmico; C - 3% de levedura inativa, 2% de levedura hidrolisada, 4% de plasma. Ração Pré Inicial 2 - A - 4% de levedura inativa, 3% de plasma, 0,8% de ácido glutâmico; B - 3% de levedura inativa, 1% de levedura hidrolisada, 3% de plasma e 0,8% de ácido glutâmico; C - 3% de levedura inativa, 1% de levedura hidrolisada, 3% de plasma. Ração Pré Inicial 3 - A - 2% de levedura inativa, 1,5% de plasma, 0,6% de ácido glutâmico; B - 2% de levedura, 0,5% de levedura hidrolisada, 1,5% de plasma e 0,6% de ácido glutâmico; C - 2% de levedura, 0,5% de levedura hidrolisada, 1,5% de plasma. E o experimento 2 teve os seguintes tratamentos: Ração Pré Inicial 1 - A - 5% de levedura inativa, 3% de plasma; B - 5% de levedura inativa, 3% de plasma e 1% de ácido glutâmico; C - 3% de levedura inativa, 2% de levedura hidrolisada, 3% de plasma e 1% de ácido glutâmico. Ração Pré Inicial 2 - A - 4% de levedura inativa, 2% de plasma; B - 4% de levedura inativa, 2% de plasma, 0,8% de ácido glutâmico; C - 3% de levedura inativa, 1% de levedura hidrolisada, 2% de plasma e 0,8% de ácido glutâmico. Ração Pré Inicial 3 - A - 2% de levedura inativa, 1,0% de plasma; B - 2% de levedura inativa, 1,0% de plasma, 0,6% de ácido glutâmico; C - 2% de levedura, 0,5% de levedura hidrolisada, 1,0% de plasma e 0,6% de ácido glutâmico. A levedura hidrolisada demonstrou aspectos positivos para sua utilização em dieta de leiões nas fases críticas pós desmama podendo promover melhora no desempenho zootécnico e na morfologia intestinal dos animais.

Abstract in English
The objective of this study was to evaluate the addition of different levels of hidrolysed and inactive yeast (Saccharomyces cerevisiae) in feed, with spray dried blood plasma and glutamic acid on performance and intestinal morphology of weaned piglets. Two experiments were conducted, each with three treatmens, four replicates with 22 animals in the nursery phase (21 to 59 days of age), totaling 264 pigs per experiment. The piglets were distributed in randomized block design in both experiments. The experiments were divided in four phases corresponding experimental diets: pre - starter 1 (21-28), pre - starter 2 (29-35), pre - starter 3 (36-42). Experiment 1 had the following treatments: Pre starter 1 - A - 5% of inactive yeast, 4% plasma, 1% glutamic acid; B - 3% of inactive yeast, 2% hydrolyzed yeast, 4% plasma and 1% glutamic acid; C - 3% inactive yeast, 2% hydrolyzed yeast, 4% of plasma. Pre starter 2 - A - 4% inactive yeast, 3% plasma, 0.8% glutamic acid; B - 3 % inactive yeast, 1% hydrolyzate yeast, 3% plasma, 0.8% glutamic acid; C - 3% inactive yeast, 1% hydrolyzate yeast, 3% of plasma. Pre starter 3 - 2% inactive yeast, 1.5% plasma, 0.6% glutamic acid; B - 2% inactive yeast, 0.5% hydrolyzate yeast, 1.5% and plasma 0 6% glutamic acid; C - 2% inactive yeast, 0.5% hydrolyzate yeast, 1.5% plasma. And the experiment 2 had the following treatments: Pre starter 1 - A - 5% inactive yeast, 3% plasma; B - 5% inactive yeast, 3% plasma and 1% glutamic acid; C - 3% inactive yeast , 2% hydrolyzate yeast, 3% plasma and 1% glutamic acid. Pre starter 2 - A - 4% inactive yeast, 2% plasma; B - 4% inactive yeast, 2% plasma, 0.8% glutamic acid; C - 3% inactive yeast, 1% hydrolyzate yeast, 2 % plasma and 0.8% of glutamic acid. Pre starter 3 - A - 2% inactive yeast, 1.0% plasma; B - 2% inactive yeast, 1.0% plasma, 0.6% glutamic acid; C - 2% inactive yeast, 0, 5% hydrolyzate yeast 1.0% of plasma and 0.6% glutamic acid. Yeast hydrolyzate showed positive aspects to their use in diet after weaning can promote improvement in performance and intestinal morphology of animals.
