NOTE: Where experimental data are lacking, values typeset in bold italics represent estimates based on values obtained from other ages or relate species or from modeling experiments.

a The age intervals for nutrient requirements of males are based on actual chronology from previous research. Genetic improvements in body weight gain have led to an earlier implementation of these levels, at 0 to 3, 3 to 6, 6 to 9, 9 to 12, 12 to 15, and 15 to 18 weeks, respectively, by the industry at large.

b The age intervals for nutrient requirements of females are based on actual chronology from previous research. Genetic improvements in body weight gain have led to an earlier implementation of these levels, at 0 to 3, 3 to 6, 6 to 9, 9 to 12, 12 to 14, and 14 to 16 weeks, respectively, by the industry at large.

c These are approximate metabolizable energy (ME) values provided with typical corn-soybean-meal-based feeds, expressed in kcal MEn/kg diet. Such energy, when accompanied by the nutrient levels suggested, is expected to provide near-maximum growth, particularly with pelleted feed.

d Turkeys do not have a requirement for crude protein per se. There, however, should be sufficient crude protein to ensure an adequate nitrogen supply for synthesis of nonessential amino acids. Suggested requirements for crude protein are typical of those derived with corn-soybean meal diets, and levels can be reduced when synthetic amino acids are used.

e The calcium requirement may be increased when diets contain high levels of phytate phosphorus (Nelson, 1984).

f Organic phosphorus is generally considered to be associated with phytin and of limited availability.

g These concentrations of vitamin D are considered satisfactory when the associated calcium and phosphorus levels are used.

h Requirement may increase with wheat-based diets.
