Analyzed composition and TMEn of spray-dried animal plasma and soybean meal in Experiment 1 (DM basis1).
| Spray-dried animal plasma2 | Soybean meal2 | SEM | |
|---|---|---|---|
| Crude protein (%) | 84.7 | 52.4 | |
| Crude fat (%) | 0.02 | 0.54 | |
| Acid detergent fiber (%) | 0.7 | 9.8 | |
| Neutral detergent fiber (%) | 3.1 | 10.7 | |
| P (%) | 1.41 | 0.67 | |
| Ash (%) | 8.62 | 6.92 | |
| Gross energy (kcal/kg) | 5,192 | 4,741 | |
| TMEn (kcal/kg)2,3 | 3,743 | 2,669 | 114 |
1
DM values for spray-dried animal plasma and soybean meal were 92.9% and 90.0%, respectively.
2
Spray-dried animal plasma and soybean meal were fed to conventional roosters as a 50% blend with corn; TMEn values were calculated by the difference procedure, factoring out the corn contribution.
3
Values are means of 4 individually-caged conventional roosters. The probability value for the model from the ANOVA was P < 0.0001 indicating that the TMEn of spray-dried animal plasma was significantly higher than soybean meal.
