Program Gut Health

The first concern is inflammatory stress, due to high feed intake and/or coccidiosis. Broilers have high genetic potential with significant feed intake capacity. Even minor digestion and absorption violations increase the quantity of nutrients available to opportunistic bacteria in the gut. Any resulting chronic inflammation or coccidiosis lesions can cause villus atrophy.

Some nutritional factors can favour potential pathogens like Clostridium to the cost of other beneficial bacteria, such as Lactobacillus. This high stressor pressure can become a vicious circle.


A damaged gut displays villi fusion, excessive mucus production and an immune reaction. Further inflammation then appears, following these reactions.

Fusion of the villi leads to a reduced exchange surface, with lower water absorption (thus watery faeces) and less nutrient absorption. These nutrients will then be more available for opportunistic bacteria. Without appropriate action, this vicious circle will cause increased damage, and possibly even death for birds with necrotic enteritis.

The following illustration represents the evolution of an enteritis, demonstrating this vicious circle, where each phase has an impact on gut morphology and microbiology.

Enhancing pathogen control and gut integrity

Phileo dash

Safmannan® is a premium yeast fraction, rich in mannan-oligosaccharides and beta-glucans (1.3 and 1.6). Thanks to its ability to bind pathogens and preserve gut development, Safmannan® helps break the vicious circle of bacterial enteritis in birds.

 

Safmannan® helps maintain better ileal villus height, compared to enramycin treatment in broilers, under Clostridium perfringens (C. perf.) challenge.

 

Nucleosaf® is a premium yeast extract, rich in nucleotides, which are known to have a significant effect on the immune system, plus certain tissues with a high renewal rate, such as the intestinal tract. A broiler study carried out in Mexico proved that supplementation with Nucleosaf® at 500g/t for 21 days improved the performance of birds by increasing the absorptive surface area and enhancing barrier functions in the intestine.

Increasing resistance to oxidative stress

Selsaf® is a natural source of organic selenium with a dual mode of action. Selsaf® optimises the activity of Glutathione peroxidase (GPx), a key enzyme of the antioxidant mechanism. It also significantly increases the level of selenium in the muscles of birds, compared to sodium selenite and other selenium yeasts.

Improving health: Safmannan® decreases mortality

Phileo dash

A trial was conducted at the Southern Poultry Research Inc. on 1,600 male Cobb broilers. The animals were challenged with coccidia, followed by a three-day inoculation of Clostridium perfringens (C.perf.). Results showed that Safmannan® significantly reduced mortalities.

Safmannan®, Nucleosaf®, and Selsaf®: improving feed efficiency and growth

Phileo dash

Safmannan® significantly improved the feed efficiency and bodyweight of broilers, compared with a control group, during a trial in Mexico in 2015.

 

By increasing the absorptive surface area and enhancing barrier function in the intestine, after 21 days of supplementation with Nucleosaf® (500g/t), broilers’ bodyweight increased by 8% Vs. a control group at 35 days of age, with a significantly better FCR.

 

Trial evidence has shown that Selsaf® improves FCR and bodyweight in broilers compared to other sources of inorganic (sodium selenite) and organic (synthetic seleno-methionine) selenium.
