Nuscience: Babi®star Safe: creating an exogenous defence shield
Piglets face a lot of stressors around weaning. On top of this, newly weaned piglets have a limited immunity. All these factors have a huge impact on the health and performances of the animals. To help piglets with a suboptimal health status, Nuscience developed Babi®star Safe. This prestarter feed supports the health of animals around weaning by creating an exogenous defence shield. This exogenous defence shield avoids a health reduction and the overstimulation of the endogenous immune system, sparing energy for growth. In this way it is possible to support the health of piglets around weaning, without reducing their growth performance.
The challenges around weaning are numerous: pathogens pass the stomach due to an inadequate acidification of the stomach, a low feed intake resulting in intestinal damage, pathogens like E. Coli attaching to the intestinal wall, limited energy intake and stress result in a loss of gut barrier function, a limited digestive capacity, intestinal dysbiosis, oxidative stress, the formation of endotoxins,… These factors result in a reduced animal health and an overstimulation of the endogenous immune system, wasting a lot of energy and nutrients. It is known from literature that an immune challenge has huge influences on the growth performance of animals. From broiler studies it is estimated that in healthy animals the lysine requirement of the immune system is about 1-2% of the total requirement. However during a health challenge, this increases to 9% (Klasing, 2007). In a meta-analyses of different challenge tests, the effects of an endotoxin challenge, intestinal bacterial infections or poor housing conditions resulted respectively in a 12.2%, 16.5% and 9.6% reduced growth performance of piglets (Pastorelli et al., 2012).
Babi®star Safe, part of the Babi® Robust feeding line, creates an exogenous defence mechanism based on a 5- fold approach with different innovative feed ingredients: Killing of bacteria entering the stomach of piglets – Improving immunity of piglets – Maintaining the gut barrier function – Capturing bacteria and toxins – Blocking endotoxins from binding on intestinal receptors. To create this endogeneous defence shield Nuscience developed a dedicated combination of medium chain fatty acids, specific organic acids, natural antioxidants, an endotoxin binder, a prebiotic fibre that is shown to agglutinate pathogenic bacteria like E. Coli, and a newly introduced specific fibre extract (SpeCiFiC) that is shown to inhibit endotoxins from binding on their intestinal receptors. The latter fibre extract avoids an over-stimulation of the immune system and improves the gut barrier function. In Nuscience trials, this extract resulted in an 8% improved growth performance around weaning (Table 1).

Moreover, Babi®star Safe also optimizes the protein digestion, and uses a specific adapted amino acid profile. It is shown that health-challenged animals need a different amino acid profile compared to animals that are reared in high sanitary circumstances.
Thanks to Babi®star Safe, the animal health can be improved without severely reducing the crude protein content of the feed, resulting in excellent growth performances! By feeding Babi®star Safe from 7 days before weaning till 2 weeks after weaning, the health and growth performances of piglets can be optimized alsounder low sanitary statuses.
