The Challenge
Non-starch polysaccharides (NSP) found in feed ingredients negatively affect the nutritional value and digestibility of swine diets. Furthermore, non-digestible fractions of polysaccharides other than arabinoxylans and beta-glucans can heighten these detrimental effects on the digestibility and nutrient release from various raw materials. Galacto- oligosaccharides from soybean meal (SBM), quantified to be present in up to 10% (DM basis), can go undigested and cause negative effects due to the lack of specific enzymes to hydrolyse them within the animal gastrointestinal tract.
Kerry AlphaGal™, a multicomponent enzyme, can target both the oligosaccharides and other NSP in the diet, therefore unlocking additional value to swine feed.
Our Solution
Kerry AlphaGal™ Enzyme Helps
• Reduce the effect of anti-nutritional factors in swine diets, particularly affecting nursery pigs
• Optimize the nutritive value of raw materials within feeds for swine
• Improve feed digestibility by sparing more energy
• Support feed cost reduction and improve overall profitability
Randomized Controlled Results
Elevate Digestible (DE) and Metabolizable Energy (ME) from soybean meal in nursery pigs Nursery pigs are particularly sensitive to the presence of oligosaccharides from SBM.
Research has shown that Kerry AlphaGal™
can linearly increase the content of DE (Linear;
p<0.05) and ME (Linear; p=0.09) of SBM up to 300 kcal/kg (as-fed basis) (Fig. 1; Espinosa, 2016).
These nutritional benefits can also support performance in nursery pigs fed above normal levels of SBM or with low energy density diets (Fig. 2).

Importance of adequate energy density in grow-finishers
Lowering the energy density of grow-finisher pigs has a detrimental impact on growth
performance. For every 10 kcal/kg ME reduction, growth rates can be reduced up to 9 g/day, with associated increases in FCR of up to 4 points (Figure 3). Kerry AlphaGal™ can mitigate this impact in grower-finishers by helping pigs utilize dietary components more effectively. Regression analysis quantified Kerry AlphaGal™ energy equivalence in ~55 kcal/kg in a randomized controlled evaluation.

The net impact of the improved nutrient availability of Kerry AlphaGal™ is reflected in shorter duration of the fattening period together with increased yields when used to complement commercial practical grow-finisher diets (Fig. 4).

Improved nutrient digestibility:
Effect on NSP hydrolysis
The fiber content and composition of swine feed can have a direct impact on the energy density of the diet because of inefficiencies in nutrient digestibility. Lowering the energy content of swine feeds has been shown to reduce the apparent total tract digestibility (ATTD) of DM, CP and GE across the various feeding phases from wean-to-finish. Kerry AlphaGal™ has shown to help correct this deviation in digestibility to level equivalent of diets meeting nutrient requirements (Figure 5). Kerry AlphaGal™ can also improve the digestibility of specific sugars derived from NSP, namely galactose, mannose and xylose (Figure 6), supporting its unique mode of action and substrates for hydrolysis.
