英文文献摘要：
Phytase represents a potential win/win management practice for non-ruminant producers since it can reduce the need for phosphorous supplementation and also result in lower phosphorous runoff. Cost of phytase has decreased and cost of phosphorous has increased. The reported adoption rate for phytase for non-ruminants was 17.2 percent, however it is currently added to virtually all swine and poultry premixes by feed manufacturers due to the cost savings. People were more likely to say they use phytase if they think it is profitable, not time intensive, and improves water quality.
