O estudo foi conduzido para verificar a influência da glutamina no turnover do carbono em tecidos de leitões. Nove porcas foram cobertas e receberam dietas compostas predominantemente por grãos de plantas do ciclo fotossintético C4 durante gestação e lactação. Aos 21 dias de idade, 48 leitões foram distribuídos aleatoriamente nos tratamentos: T1 = dieta C3, sem suplementação de glutamina, e T2 = dieta C3, suplementada com 1% de glutamina. Nos dias 0, 1, 2, 3, 4, 5, 8, 11, 15, 20, 29 e 46 pós-desmame, foram abatidos dois leitões/tratamento. Amostras dos músculos Psoas major e Masseter, fígado e pâncreas foram coletadas e analisadas quanto à composição em d‰13C e mensurada a substituição do carbono em função do tempo. A glutamina acelerou a substituição do carbono em ambos os músculos, como observado pelos valores de meia-vida (T) destes tecidos (T = 51,4 e 21,7 dias para Masseter e 31,5 e 20,3 dias para Psoas major, nos tratamentos sem e com suplementação de glutamina, respectivamente). Os valores de meia-vida do carbono das vísceras indicam que esse aminoácido também acelerou o turnover do carbono nestes órgãos. Os resultados indicam estímulo anabólico da glutamina sobre os tecidos avaliados.The study was carried out to verify the influence of glutamineon carbon turnover in the muscles and viscera of piglets. Nine sows were bred and received diets predominantly composed by grains of C4 photosynthetic cycle plants during gestation and lactation. The piglets were weaned at 21 days of age, and 48 animals were distributed at random in two treatments: T1 = C3 diet, without glutamine supplementation; and T2 = C3 diet, supplemented with 1% glutamine. On days 0, 1, 2, 3, 4, 5, 8, 11, 15, 20, 29 and 46 postweaning, two piglets per treatment were slaughtered. Samples of the Psoas major and Masseter muscles, liver and pancreas were collected and analyzed for d‰13C composition, and carbon turnover was measured as a function of time. It was verified that glutamineaccelerated the carbon turnover in both studied muscles, as observed for the half-life values of these tissues (T = 51.4 and 21.7 days for Masseter, and 31.5 and 20.3 days for Psoas major, in the treatments without and with glutamine supplementation, respectively. The half-life values of the carbon for the liver and pancreas, with and without glutamine treatments, indicate that this amino acid also accelerated the turnover of the carbon in these organs. Theresults indicated anabolic stimulus by glutamine on the evaluated tissues. |
