“…La baja digestibilidad de treonina, puede deberse en parte, a su baja tasa de absorción en el intestino d e l g a d o . A d e m á s , b a s a d o s e n l a especificidad de proteasas y peptidasas endógenas, treonina es el último AA liberado por la hidrólisis enzimática en la proteína (32). El nivel y tipo de fibra afectan la digestibilidad aparente de AA, ya que incrementan las pérdidas endógenas de AA.…”

RESUMENObjetivo. Obtener los coeficientes de digestibilidad ileal aparente (CDIA) de proteína (PC) y aminoácidos (AA) de torta de canola, en lechones recién destetados. Materiales y métodos. Se utilizaron 24 lechones destetados a los 17 días de edad con un peso de 5.5 kg, a los cuales se les fijó una cánula simple en "T" en el ileon distal. Los lechones recibieron uno de los siguientes tratamientos: Dieta de Referencia (C) elaborada con caseína y almidón de maíz; dietas CTC (caseína-10% de Torta de canola) y CTCP (caseína-10% de torta de canola peletizada). Resultados. Los CDIA de PC y AA de la dieta C fueron superiores (p<0.05), con excepción de algunos aminoácidos de CTCP que tuvieron CDIA similares (p>0.05) a C. No se observó un efecto (p>0.05) del periodo (tiempo posdestete) sobre los CDIA de la PC y AA, exceptuando al aminoácido metionina. Los CDIA del nitrógeno (N) y AA de TCP fueron mayores (p<0.05) que los de TC. Conclusiones. La TCP puede ser incluida en dietas de lechones en un 10% empleando los coeficientes reportados en este trabajo.Palabras clave: Lechones, canola, aminoácidos, digestibilidad ileal. ABSTRACTObjective.

“…Normally, there is a great surplus of digestive capacity in the small intestine (Low, 1980). Dietary fibre will influence in vivo digestion in several ways, depending on the nature of the fibre.…”

“…This has been questioned since it is non physiological [3] and it affects protein synthesis rate of the whole body and the amount of protein entering the gut [4]. In baby calves, small intestinal villus-crypt architecture and digestive enzyme activities of the mucosa were drastically reduced with a PF diet [5].…”

-The consequences of feeding a protein-free (PF) diet, as compared to casein, on gut characteristics were studied in slightly energy-restricted rats fed similar amounts of feed for 10 d. The weight and pH of fresh digesta in the stomach were lower (P = 0.045 and P = 0.016). However, the weight of fresh digesta in the other segments and gut tissue weight were not significantly affected by the diet (P > 0.05). Small intestinal crypt depth, width and area were reduced by 13, 23 and 37%, respectively (P = 0.011, P = 0.004 and P = 0.001), and villus width tended to be smaller (P = 0.057), with the PF diet. Villus height to crypt depth ratio was also lower with the PF diet in the duodenum and ileum, respectively (P < 0.05). Finally, the specific activities of alkaline phosphatase and aminopeptidase N were reduced by 36 to 38% at different sites of the small intestine in the rats fed the PF diet (P < 0.05). In conclusion, chronic consumption of a protein-free diet altered the intestinal villus-crypt architecture and enzyme activities in rats.rat / protein-free diet / intestine / villus-crypt architecture / enzyme
