Absorption of 3-oxy-methyl-d-glucose by chicken cecum and jejunum in vivo

Transport and expression of transporters for 3-O-methyl-D-glucose and L-methionine along the intestine of broiler chickens receiving different methionine supplements

“…This would support a concept of relevant AA absorption across caecal intestinal epithelial cells. Unlike mammals, chickens were proposed to exhibit transporter-mediated nutrient absorption throughout the entire intestinal tract, including the caeca ( Vinardell et al, 1986 ; Moreto et al, 1989 ). However, other studies concluded that carrier-mediated Met absorption in CAE diminishes rapidly within the first week of life ( Lerner et al, 1975 ).…”

“…The reason for differences in bio-efficacy of different Met supplements could include different metabolic conversions or different nutrient absorption ( Maenz et al, 1996 ; Drew et al, 2003 ). Interestingly, when compared to mammals, chickens exhibit nutrient absorptive capacities throughout their entire intestinal tract, including the large intestinal regions ( Vinardell et al, 1986 ; Moreto et al, 1989 ). Met absorption can occur through multiple Na + -dependent and Na + -independent carrier-mediated systems.…”

The Effectiveness of Ligating or Detaching Ceca as an Alternative to Cecectomy

“…Are any of the cecal contents fermentable? If so, could the products be transported back into the blood stream, e.g., passive diffusion of VFA (Sudo and Duke, 1980) or active transport of nutrients (Ferrer et al, 1986;Vinardell et al, 1986), just as they are in intact ceca?…”

“…In time, the cecal walls might have ruptured, releasing cecal contents into the peritoneal cavity. The distension may result from impaired absorptive capacity in detached and ligated ceca: because the proximal region of the ceca is known to be the most effective absorptive surface of the organ (Ferrer et al, 1986;Vinardell et al, 1986) and it is the area that is damaged by cecal ligation or detachment.…”
