The water swelling of feed particles increases the surface area, becomes soft and is conducive to pig feed and digestion and absorption reduces feed waste and improves feed conversion rate.
The digestibility of the growing pigs and the growing pigs can be increased by 9.19%~12.08% because of the mixture of feed nutrients and the palatability.
The utilization rate of corn phosphorus in the conventional diet was 15%, while that in the liquid diet was as high as 45%. More than 85% of phytate phosphorus was released when phytase was added to wet corn or corn extract.
Therefore, wet corn-based liquid diet, total phosphorus growth pigs fell to 0.47%, fattening pigs reduced to 0.39%, and growth performance were not affected. The production performance of piglets was normal when the total phosphorus of liquid diet decreased to 0.6% in the early stage and 0.54% in the late stage.
