2 Soybean meal, solvent extracted, international feed #: 5-40-604. Nutrient Requirements of Poultry: Ninth Revised Edition, 1994
3 Menhaden fish, international feed #: 5-20-009. Nutrient Requirements of Poultry: Ninth Revised Edition, 1994
4 ME for larvae meal and pupae meal were calculated from DE values (ME = 0.82 x DE)
5 This is total phosphorus. Soybean meal has 0.30% non-phytate phosphorus
Abbreviations used are NFE, nitrogen-free extract; TDN, total digestible nutrients; ME, metabolizable energy.
