A healthy gut in animals is one that has a stable and diverse microbial flora. The more diverse, the healthier the animal.


sodium butyrate. This allows butyrate to reach the distal part of the intestinal tract. In a trial, the effect of Butifour CCB was evaluated on the performance and gut health of broilers fed a corn soya diet. 720 ROSS 308 male broilers were divided over 18 pens with 40 broilers each and each replicate (n=9) was allocated to one of the two treatments. The addition of the specific coated calcium butyrate to a standard commercial diet increased significantly body weight with 3 % (+85 grams) at 39 days. The higher body weight is explained by the improved absorptive capacity expressed as villus length and villi to crypt ratio.


Intestinal health scores Intestinal health is a key factor for zootechnical performance of the animals. Figure 1 shows morphological scorings at slaughter age of duodenal samples. A lower mean rank corre- sponds with a less severe alteration. Infiltrates stands for the amount of inflammatory cells migrated into the epithelial lay- er, cysts indicates the amount of cysts and abscess present in epithelial crypts, suggesting encapsulation of invasive parti- cles, whereas desquamation describes the amount of shed- ding of epithelial cells in the lumen. To be able to combine all intestinal scores in one number, we allocated an impact fac- tor for each score, based on the effect on the animal’s health status. This resulted in an overall duodenal morphology score.


These morphological observations showed an improved intestinal health status with Butifour CCB. In another broiler trial, the specific coated calcium butyrate was combined with an effective combination of short chain fatty acids (Acidal NC). In comparison with the single additive, the combination resulted in heavier birds at slaughter. In the starter phase, the FCR was significantly better for the combination. The starter phase is crucial for the development of a healthy gut. It has been demonstrated that the addition of the effective combination stimulated the proliferation of crypt cells. This is enhancing the healthy tissue turnover and leads to better absorption of nutrients. Furthermore, the combination supports the birds in developing a balanced gut microflora. A better FCR is a direct consequence of better overall intestinal health.


Improve gut health for top performance It can be concluded that Butifour CCB is an indispensable molecule in the nutritional toolbox for optimal development and functionality of the digestive system resulting in gastro- intestinal health and leading to better zootechnical perfor- mance. In addition, it has been proven that it can be used to- gether with other short and medium chain fatty acids, as well as with natural extracts, combining different strategies to protect the entire digestive tract and to ensure good gut health to get the best performance from your broilers.
