Butyrate has positive effects on immune development, gut development and motility and helps to reduce harmful bacteria such as Salmonella.
However, this can only be achieved if the right amount of butyrate is delivered through critical areas throughout the intestinal tract. For this reason, Nutriad has designed a specific butyrate with a built-in precision delivery mechanism.
In recent research done at the University of Illinois (Prof. Stein & colleagues, 2012) the importance of a good coating was again demonstrated. The researchers investigated the disappearance kinetics of different sources of butyrate in diets fed to weanling pigs. Weanling pigs were randomly allotted to 3 dietary treatments: 1) a control diet, 2) the control diet + 4kg/T of an uncoated butyrate (50% product, UCB), 3) the control diet + 4kg/T of a coated butyrate (30% product, CB).
The dietary treatments were provided to pigs daily for 7 days as 3 times the estimated energy requirement for maintenance. On the last day of the experiment, samples of contents in stomach, duodenum, jejunum, ileum, cecum were collected and analysed. Weanling pigs fed the CB diet had greater (P<0.05) concentrations of butyrate in the jejunum (190%) and ileum (188%) than weanling pigs fed the control diet (µg butyrate/g digesta DM put as 100%). In conclusion, the coated butyrate, in spite of lower percentage of butyrate (30%), increased significantly the concentrations of butyrate in the lower intestinal contents of pigs. Supplementation of the more concentrated (50%) but less protected butyrate did not result in significant differences in the amount of butyrate in the intestinal tract compared with the control group.
This trial demonstrates that not the amount of butyrate administered is the most important; on the contrary, the technology designed to distribute the butyrate into the intestinal tract is an even more relevant factor.
