| Five hundred and four 1-day-old Cobb broiler chickens were randomly allotted to 18 treatments and fed a semi-purified basal diet (4 g/kg total phosphorus) supplemented with 2 levels of supplemental P (0.5 or 1 g/kg) during 21 days to evaluate performance and bone mineralization; to assess the relative bioavailability of P (RBP) in wheat meal (WM) and roasted (RS) or extruded soybean meal (ES), with or without phytase (0 or 750 ftu/kg diet), using dicalcium phosphate (DC) as standard; and to estimate phosphorus excretion. Weight gain (WG), feed intake (FI), feed to gain ratio (FG), and tibia ash weigh (AW) were assessed. For each source, the RBP was calculated by the slope ratio method, when tibia ash weight was regressed on P ingested. Ingested and fecal P... |

| Quatrocentos e vinte pintos de corte Cobb 500, machos de 1 dia de idade, foram distribuídos aleatoriamente em 15 tratamentos com 4 repetições, em teste utilizando baterias (7 aves/gaiola), com duração de 21 dias, para determinar a biodisponibilidade relativa de fósforo (BRP) em três ingredientes, com duas características genéticas (baixo fósforo fítico ou convencional). Utilizou-se uma dieta basal semipurificada, à base de milho e farelo de soja, adicionada de cevada convencional, cevada com baixo fósforo fítico, milho convencional, milho com baixo fósforo fítico, farelo de soja convencional, farelo de soja com baixo fósforo fítico e de fosfato bicálcico em substituição ao amido de milho, de modo a fornecer 0,05 ou 0,10% de fósforo suplementar, totalizando... |

| One hundred ninety two swine were used in a trial to assess the relative bioavailability of phosphorus (RBP) in six phosphate sources. Phosphates were three feed grade phosphates (FP), two made in Brasil, and one USA made, and three rock phosphate samples (RP) originated from two mines sites in Brasil, and one mine site in Israel. Levels of calcium, phosphorus and fluorine in RP were 29, 12 and 1.7% (RP source 1), 33, 14 and 1.4% (RP source 2), and 30, 14 and 3.6% (RP source 3), respectively. Pigs were fed a corn-soybean meal basal diet (18% CP, 0.95% Lys, 0.75% Ca, 0.37% P) or the basal diet with 0.15% P from a standard purified grade calcium phosphate (SP), or with 0.15% P from experimental FP or RP. Each diet was fed to six pen replicates of four pigs... |
