The gamebird starter/grower diet is formulated to provide 230.2 kcal, 22 g protein, and 41.5 mg Fe per 100 g diet. Macronutrient and micronutrient contents were analyzed in duplicate (macronutrients and amino acids: AOAC official methods, University of Missouri-Columbia Agricultural Experiment Station Chemical Laboratories; iron: AIB International). New FBFs were prepared at 20% solids. CSB+, corn-soy blend plus; CSB14, corn-soy blend 14; FBF, fortified blended food; N-SC, nonextruded sorghum-cowpea; O-SC, overprocessed sorghum-cowpea; SC, sorghum-cowpea; SPI, soy protein isolate; SS, sorghum-soy.
Values are lower than NRC requirements for 0- to 42-d-old broiler chickens (26).
New FBFs prepared at 20%, CSB+ at 13.79% solids.
