In modern livestock management, feed additives play an important role in animal nutrition. They help improve the utilization of the nutrients in feed, leading to increased performance and profitability.
Feed prices accounts for about 70% of total pig production costs. Feed utilization, however, is not optimal. Pigs cannot digest 15-25% of their feed rations because they lack fiber or non-starch polysaccharide (NSP) degrading enzymes in their intestinal tract. If NSP digestibility could be improved it would significantly increase feed utilization, both directly and indirectly. Increased fiber digestibility would also increase the availability of other nutrients that are trapped within the fiber matrix. As a result, the energy supply from the fiber itself would also increase, and fewer nutrients will be lost to the environment.
The objective of this paper is to:
- Introduce a novel high-through-put method for quantifying the effect of in vivo NSP enzyme production from BioPlus YC dual strain Bacillus by determining the conversion of biomass (feed) with high fiber content into reducing-sugars that can be absorbed by the pig.
- Illustrate the potential return-on-investment from adding BioPlus YC dual strain Bacillus in grower diets in a commercial field trial
