TL;DR: Opportunities available to reduce the P content of livestock manure are reviewed, including more accurate interpretation of the published P requirements of animals, improved diet formulation and group-feeding strategies to more precisely meet requirements, and approaches to improve availability of feed P for monogastric and ruminant species.

TL;DR: The additions of citric acid and phytase to weanling pig diets were each beneficial, but no synergistic effects were observed.

TL;DR: Based on performance, bone measurements, and digestibilities of P, Ca, and DM of young pigs, the efficiency of Phytaseed was similar to that of Natuphos for enhancing the utilization of phytate P in corn-soybean meal-based diets.

TL;DR: Two 5-wk experiments were conducted to determine the effects of water and diet acidification with and without antibiotics on weanling pig growth performance and microbial shedding and there was a tendency for an improvement in ADG when DA was added to the NC or TC, but decreased ADGWhen DA wasadded to CB.

TL;DR: Based on performance, bone characteristics, and retention of P, Ca, and DM of young broilers, the efficacy of Phytaseed phytase was similar to that of Natuphosphytase for enhancing the utilization of phytate P in corn-soybean meal-based diets.
