Effect of cereal soaking and carbohydrase supplementation on growth, nutrient digestibility and intestinal microbiota in liquid-fed grow-finishing pigs.


ABSTRACT: Soaking the cereal fraction of a liquid diet prior to feeding (Csoak), and/or carbohydrase enzyme supplementation (ENZ) are likely to modulate both feed and intestinal microbial populations and improve feed efficiency (FE) in pigs. To test this hypothesis, a total of 392 grow-finisher pigs (~33.4?kg, 7 pigs/pen) were randomly allocated to 4 treatments in a 2?×?2 factorial arrangement for 70 days as follows: (1) fresh liquid feed (Fresh); (2) Cereal soaked liquid feed (Soak); (3) Fresh?+?ENZ and (4) Soak?+?ENZ. An interaction between ENZ and Csoak was found for average daily gain (ADG) during the growing phase (day 0 to 21; P?soak 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.
