Soaking and enzyme supplementation of liquid grow-finish pig diets
Soaking and enzyme supplementation of liquid-fed grow-finish pig diets can improve nutrient digestibility.
As a result, an interaction between ENZ and Csoak was found for average daily gain (ADG) during the growing phase (day 0 to 21) where pigs fed the Soak + ENZ diet had higher ADG than pigs fed the Fresh + ENZ diet. No treatment effect was found for ADG thereafter. Enzyme supplementation increased total tract nutrient digestibility and reduced caecal VFA concentrations but did not improve pig growth or feed efficiency. Both Csoak and ENZ modulated intestinal microbiota composition; increasing abundance of bacterial taxa that were negatively correlated with pig growth and reducing abundance of taxa positively correlated with pig growth and caecal butyrate concentration.
In conclusion, both strategies (Csoak and ENZ) improved nutrient digestibility in pigs and modulated intestinal microbiota composition.
