“…Several studies have evidenced improvements on piglets' growth performance by adding glutamine (Kitt et al, 2002;Abreu et al, 2010) and glutamate (Molino et al, 2012) in diets; however, this could not be proved in the present study, since the growth performance of piglets fed these additives was similar to those fed control diets. Yi et al (2005) and Tucci et al (2011) added glutamine (2 and 1%, respectively) in weanling piglet diets and found no differences on performance. This could be attributed to the fact that no immune challenge was imposed during the trial period, which may have inhibited the action of the additives, although piglets had been stressed during weaning.…”

The objective of this work was to evaluate the effects of dietary glutamine and glutamic acid supplementation on carbon turnover (δ13C) in the muscles of piglets, on animal performance, and on feed economic feasibility. The diets consisted of: control (C), 1% glutamine (G), and 1% glutamic acid (GA). In experiment I, 111 piglets were used to assess carbon turnover in the Masseter, Psoas major, and Abdominal internal oblique muscles in terms of their isotopic composition and 13C substitution over time. In experiment II, 72 piglets were assigned randomly to blocks (eight replicates per treatment and three animals per experimental unit), in order to evaluate animal performance and feed economic feasibility. The GA diet promoted the best 13C acceleration in the studied muscles. No diet effects were observed on performance variables. The G and GA diets presented higher costs than the C diet. Although supplementation with 1% glutamine or glutamic acid accelerates carbon turnover in the studied muscles, which suggests a faster recovery during post-weaning and proves the anabolic effect of these additives, its use is not economically viable for weanling piglets.

“…Liu & Jian (1999) found that the supplementation of both glutamine (Gln) and glutamate (Glu) improved the live performance of weaned piglets. In according to Tucci et al (2011b), the employment of glutamine in the diet was not effective to influence the performance of piglets in the weaning process. Abreu et al (2010) did not observe any improvement in the performance of piglets during the first two weeks after weaning when glutamine was individually included in the diet, and suggested that the low health challenge during the experimental period may explain the observed lack of glutamine effects.…”

The effects of dietary inclusion levels of the association of glutamine with glutamic acid (AminoGut: AmG) on the performance, gastrointestinal morphophysiology, and diarrhea incidence of piglets weaned at 21 days of age were evaluated. In the experiment, 120 piglets with 6.24 ± 1.00 kg initial weight were distributed according to a randomized block experimental design into five treatments with six replicates of four animals each. The following treatments were applied: negative control diet (0% AmG); 0.5% AmG; 1.0% AmG; 1.5% AmG; positive control diet (0% AmG, 4% inclusion of porcine plasma). The inclusion of 1.0% AmG, as compared to the positive control diet, improved weight gain, feed intake and feed conversion ratio. The lowest diarrhea score was observed when 1.0% AmG was included, whereas the best villus height and villus:crypt ratio were obtained with the inclusion of 0.82% AmG. Villus height, crypt depth, and villus:crypt ratio values obtained with 1.0% AmG were similar to those obtained with the positive control diet, except in the period of 21 to 28 days, when the diet with 1.0% AmG promoted higher villus:crypt ratio. The supplementation of 0.5 and 1.0% AmG affected organ weights, and reduced digestive content pH in the pylorus and in the ileum relative to the positive control diet. The dietary supplementation of 1% glutamine associated with glutamic acid improves the performance and the morphophysiology of piglets weaned at 21 days of age.

“…Os animais que compunham o grupo tratado com ração contendo Tilosina tiveram maior profundidade de cripta no duodeno em relação aos animais que receberam o simbiótico e os animais controle, sugerindo que os animais tratados com Tilosina obtiveram uma maior descamação epitelial do intestino nesta porção, pois, o aumento na descamação resulta em incremento da profundidade da cripta para assegurar a adequada taxa de renovação celular e garantir a reposição das perdas de células da região apical dos vilos (PLUSKE; HAMPSON; WILLIAMS, 1997;TUCCI, 2003). A altura de vilosidade teve comportamento contrário, com a Tilosina apresentando a pior taxa vilosidade/ cripta entre os tratamentos e a menor altura de vilosidade em relação à Colistina.…”

ResumoObjetivou-se avaliar em suínos em fase de crescimento e terminação os efeitos de promotores de crescimento sobre o desempenho, características de carcaça, perfil histológico intestinal, peso dos órgãos do trato digestório, e os reflexos desses tratamentos sobre os efluentes submetidos ao processo de biodigestão. Utilizaram-se 80 suínos, com peso médio inicial de 40,00 ± 1,90 kg, submetidos a quatro tratamentos, durante 61 dias, até atingirem 100,00 ± 4,50kg, correspondendo às dietas: Controle, Simbiótico; Colistina (10ppm); e Tilosina (40ppm). Constatou-se diferença na fase de crescimento, com maior consumo diário de ração para o tratamento Tilosina em relação ao tratamento Colistina. Não houve diferença para as características de carcaça, para o peso dos órgãos e para os parâmetros avaliados no processo de biodigestão dos dejetos (pH, sólidos totais, demanda química de oxigênio e demanda bioquímica de oxigênio). Quanto à morfometria intestinal, os animais do tratamento Tilosina apresentaram maior profundidade de cripta (P≤0,05) no duodeno em relação aos animais dos tratamentos Controle e Simbiótico, assim como maior profundidade de cripta no jejuno (P≤0,05). Houve diferença para a taxa vilosidade/cripta, com o tratamento Controle apresentando maior valor em relação aos demais tratamentos. Para o íleo, houve diferença para a profundidade de cripta dos animais do tratamento Controle em relação ao tratamento Tilosina. Apesar das diferenças observadas para as características de morfometria intestinal, não houve vantagem na utilização dos aditivos para os parâmetros de interesse zootécnico. Quanto aos efeitos sobre a fermentação dos efluentes provenientes dos animais submetidos aos tratamentos, os resultados não indicaram vantagens para nenhum aditivo.
