In order to study the rate of intestinal absorption and hepatic uptake of medium-chain fatty acids (MCFA), six growing pigs, mean body weight 65 kg, were fitted with a permanent fistula in the duodenum and with three catheters in the portal vein, carotid artery and hepatic vein respectively. Two electromagnetic flow probes were also set up, one around the portal vein and one around the hepatic artery. A mixture of octanoic and decanoic acids, esterified as medium-chain triacylglycerols, together with maltose dextrine and a nitrogenous fraction was continuously infused for 1 h into the duodenum. Samples of blood were withdrawn from the three vessels at regular intervals for 12 h and further analysed for their non-esterified octanoic and decanoic acid contents. The concentration of non-esterified octanoic and decanoic acids in the portal blood rose sharply after the beginning of each infusion and showed a biphasic time-course with two maximum values, one after 15 min and a later one between 75 and 90 min. Only 65 % of octanoic acid infused into the duodenum and 54 % of decanoic acid were recovered in the portal flow throughout each experiment. The amounts of non-esterified MCFA taken up per h by the liver were close to those absorbed from the gut via the portal vein within the same periods of time, showing that the liver is the main site of utilization of MCFA in pigs. These results have been discussed with a special emphasis laid on the possible mechanisms of the biphasic time-course of MCFA absorption and the incomplete recovery in the portal blood of the infused fatty acids.

This study evaluated the efficacy of a matrix-coated organic acids and medium-chain fatty acids blend (MCOFA) in growing pigs. Ninety six pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 47.71 ± 3.73 kg were used in a 6 wk experiment. Pigs were allotted to diets containing 0 or 2 g kg−1 of MCOFA, and 0 or 2.5 g kg−1 of antibiotic growth promoters (AGP) according to a 2 × 2 factorial arrangement of treatments. Pigs fed diets supplemented with MCOFA had improved growth efficiency compared with those fed a diet without MCOFA (P < 0.05). Pigs receiving the diets supplemented with both AGP and MCOFA had higher apparent total tract digestibility of crude protein, dry matter, fat, and gross energy (P < 0.05). Pigs fed AGP × MCOFA diet had increased serum urea nitrogen (P < 0.05). Pigs fed diets supplemented with AGP had reduced fecal ammonia (NH3) gas emissions compared with those fed without AGP (P < 0.05). Moreover, pigs fed diets supplemented with MCOFA had reduced fecal NH3 and acetic acid gas emissions compared with those fed without MCOFA (P < 0.05). In conclusion, dietary supplementation with MCOFA improved performance in growing pigs.

Background: Due to wide use of Antibiotic growth promoter builds antibiotic resistance in poultry bird. While attempting to explore potential alternative, medium chain fatty acid (MCFA) can be used due to its unique nutritional, physiological and antimicrobial property. MCFA possess activity to inhibit growth of pathogenic organism and increase the digestibility that boosts the production and growth performance of birds. The present experiment was designed to evaluate the effect of medium chain fatty acids supplementation as replacement to antibiotics in diets on growth performance and gut health in broiler.Methods: Three hundred, day-old straight-run chicks were randomly distributed into five dietary treatment groups with three replicates in each containing twenty chicks. The five treatments were, control group (T0), basal diet with antibiotic of BMD (bacitracin methylene disalicyclate) group (T1), basal diet with 0.25% lauric acid (T2), basal diet with 0.25% capric acid (T3) and basal diet with 0.25% lauric and 0.25% capric acids (T4).Result: The birds fed diet containing lauric acid, capric acid or their combination recorded significantly higher (P less than 0.01) body weight compared to control. The increase in live weight in birds fed lauric acid over control was 4.37%. Likewise, the broilers fed diets with lauric acid singly or along with capric acid recorded significantly higher gain in weights compared to other groups. The feed intake was comparable in all treatment groups. The feed conversion ratio was improved in broilers fed with MCFAs either singly or in dietary combination. The coliform count was numerically reduced, whereas, the total viable count in group fed MCFAs and their combination were substantially reduced.
