BIOPLUS® YC impacts feed digestibility

Chr Hansen conducted a feed digestibility study in the winter of 2012 to evaluate the effect of BioPlus® YC on feed digestibility in Grow-Finish swine.At a Midwest US research facility, 960 commercial Fast X PIC pigs weredivided into 2 groups at approximately 155 lbs. bodyweight. The Controlgroup was placed on a standard commercial feed diet consisting of Corn,Soybean Meal, Distillers Grains and 4% added fat (choice white grease).
The diet was balanced to meet the nutritional requirements of the pigs andincluded Phytase at 250 FTU / lb of complete feed. The Treatment group wasplaced on the identical diet as the Control group with the exception of theaddition of BioPlus® YC at the standard inclusion rate. Titanium Dioxide wasadded to both diets to serve as a marker when both the feed and pigs’ feceswere evaluated for nutrient content. There were 8 replications per group.The pigs were placed on their respective diets and allowed to consume thediet for the duration of the test. On day 4 of the study, a grab sample of feedwas taken from each feeder to be analyzed by a regional lab for nutrientcontent. On each of Day 5 and 6, a fecal sample was taken from 4 pigs ineach pen. The samples were pooled by pen and sent to a regional lab foranalysis of nutrient content.Both the feed and the feces were analyzed for Crude Fat, Crude Protein,Crude Fibre, Crude Ash, Dry Matter and Energy (Bomb Calorimeter). Theanalysis showed that there was no Energy X BioPlus® YC interaction. Themain results can be seen below in Figure 1:

Conclusion: The addition of BioPlus® YC in a commercial swine grow-finishdiet had a statistically significantly impact on Crude Fibre, Dry Matter andEnergy digestibility in growing swine, with numerical improvements inCrude Fat and Crude Protein digestibility.
