Dietary treatments were: (1) 2\u00b77 g non-phytate P (nP)\/kg; (2) diet 1 + 1000 U phytase\/kg diet; (3) 36 g nP\/kg; (4) diet 3+800 U phytase; (5) 4\u00b75 g nP\/kg; (6) diet 5+600 U phytase; (7) 6\u00b70 g nP\/kg. Added phytase and nP increased (<jats:italic>P<\/jats:italic>&lt; 0\u00b7006) tibial dry matter, ash weight and content, body-weight gain, feed intake and gain:feed. The Mg and Zn concentrations in the tibial ash were also increased (<jats:italic>P<\/jats:italic>&lt; 0\u00b7001 and<jats:italic>P<\/jats:italic>&lt; 0\u00b709 respectively) by added phytase or nP; tibial P and Ca concentrations tended to be increased. Hypertrophy zone width of the tibial proximal end decreased (<jats:italic>P<\/jats:italic>&lt; 0\u00b7001), while proliferating zone width, tibial length, and widths at the long and short axes increased (<jats:italic>P<\/jats:italic>&lt; 0\u00b7003) as phytase and nP were added. The addition of phytase also tended to enlarge the cartilaginous zone width, which was linearly increased (<jats:italic>P<\/jats:italic>&lt; 0\u00b705) by added nP. Disorganization scores of the hypertrophy zone and trabecular bone were low, approaching normal (<jats:italic>P<\/jats:italic>&lt; 0\u00b705), for turkey poults fed on diets with phytase supplementation, and tibial abnormality scores were linearly decreased (<jats:italic>P<\/jats:italic>&lt; 0\u00b7001) as nP levels increased (zero score is considered normal). Adding phytase and nP improved the orderliness of development, mineralization and arrangement of cartilage and bone cells, and alleviated the effects of P deficiency on the histological and gross structure of the tibias. Tibial shear stress increased (<jats:italic>P<\/jats:italic>&lt; 0\u00b704) as phytase and nP were added. In summary, similar improvements in bone characteristics were achieved for turkey poults fed on a P-deficient diet supplemented with either phytase or nP.<\/jats:p>","DOI":"10.1079\/bjn19960030","type":"journal-article","created":{"date-parts":[[2005,6,11]],"date-time":"2005-06-11T18:09:04Z","timestamp":1118513344000},"page":"263-272","source":"Crossref","is-referenced-by-count":14,"title":["Effects of supplemental phytase and phosphorus on histological, mechanical and chemical traits of tibia and performance of turkeys fed on soyabean-meal-based semi-purified diets high in phytate phosphorus"],"prefix":"10.1017","volume":"76","author":[{"given":"H.","family":"Qian","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.
