Implication

Demonstrates improved nutrient digestibility in growing pigs fed pulse-based diets through extrusion and enzyme addition, indicating a potential for alternative diets.

Key Points

This research aims to evaluate the effects of extrusion and enzyme addition on the digestibility of pulse-based diets for growing pigs.
Formulated Low (24% CP) and High Protein (43% CP) diets using field pea and lentil.
Conducted an 8 × 8 Latin square trial with eight diets including variations of extrusion and enzyme addition.
Used ileal-cannulated pigs for collecting feces and digesta over 9-day periods.
Analyzed the digestibility of energy, amino acids, and ash from the diets.
Extrusion significantly increased apparent total tract digestibility of gross energy and crude protein.
Enzyme addition after extrusion further enhanced the digestibility of essential amino acids and ash.
The addition of enzymes before extrusion reduced digestibility likely due to overheating effects.
