Improve feed digestibility with the Performizer® Solution - Part 2

In the first part of this article, we talked about the evolution on the feed costs and brought up the importance of feed digestibility in this matter. Get to know in the second part of this article, how Delacon can provide a phytogenic nutritional matrix that is 100% reliable.

Phytogenics lift the feed digestibility to another level

A valuable mode of action of phytogenic components is their effect on enzyme secretion. In animal trials, increased secretion of bile acids, gastric enzymes, pancreatic enzymes, and intestinal mucosa have been reported. When phytogenics were added on top of the feed, in vivo trials showed that trypsin production increased by 13%. Trypsin is an important enzyme involved in protein digestion.

Other enzymes associated with carbohydrate digestion also increased, including amylase (+25%, digestion of starch), sucrase (+15%, digestion of sucrose), and maltase (+11%, digestion of disaccharide maltose) (Figure 1_Change of enzyme activity when phytogenics are added to the feed).

In vitro cell models using Caco-2 cells have shown that phytogenics can increase the number of nutrient transporters in cell membranes. These transporters include Peptide transporter 1 (PEPT1), a cell membrane transporter involved in the uptake of peptides into the cells, and Sodium-glucose transporter 1 (SGLT1), a glucose transporter found in the intestinal mucosa (enterocytes) of the small intestine and that contributes to glucose absorption.

When Caco-2 cells were incubated with either quillaja saponins, essentials oils, or a combination of saponins and essential oils, the synergy of the specific mixture of essential oil and saponins stimulated a more significant increase in the number of transporters than either essential oil or saponins alone (Figure 2_Fold change of membrane recruitment of PEPT1). This means that the rate of nutrient absorption will increase and the digestibility of feed will be improved.

The Performizer® solution explained

Achieving higher performance is not always the objective. In some circumstances, the goal is to decrease feed costs while maintaining performance. There are various tools on the market to support the nutritionist in designing a least-cost feed formulation. For example, Biostrong® 510 is a phytogenic additive and is the basis of the C.

Analysis of ileal nutrient digestibility experiments on broilers and layers fed soy/corn/wheat rations supplemented with phytogenics demonstrated increased ileal digestibility of crude protein (CP), amino acids, fat, calcium, and phosphorus. In the control treatment, the undigested part of crude protein was on average 22.4%. Phytogenics decreased this undigested part by 3.8%, ending with an undigested part of 18.6%. When calculating the nutritional matrix values, the variability of all the trials performed is also taken into account so that the nutritional values are very conservative. By using this method of calculating nutrient matrix values, Delacon can provide nutritionists with a data set of matrix values that are 100% safe and reliable.

To sum it up

Creating a dataset to support a phytogenic nutritional matrix is not without challenges. It is vital to have a margin of safety and limit the risk of a performance decrease. Consequently, the larger the dataset, the greater the confidence in the conclusions generated. The development of the Performizer® solution is based on an extensive and consistent data set of digestibility experiments and amino acid digestibility tests. In conclusion, the detailed research shows that nutritionists can be confident that Performizer® delivers on Delacon's promise.
