In vitro digestibility of field pea as influenced by processing methods
Field pea meals exposed to different treatments (flaking, extrusion, expansion, dry heating at 150°C/15’ or 30’, dry heating at 150°C/30’ after addition of 1% of xylose, 4% NaOH addition, microwave irradiation at 800 W for 6’ or 9’) w...

| description | Field pea meals exposed to different treatments (flaking, extrusion, expansion, dry heating at 150°C/15’ or 30’, dry heating at 150°C/30’ after addition of 1% of xylose, 4% NaOH addition, microwave irradiation at 800 W for 6’ or 9’) were controlled for their 6 and 24 hours in vitro fermentability by the gas production (GP) technique. Flaking and extrusion accelerated initial fermentation but tended to reduce 24h GP, whereas dry heating and microwaves mainly improved final gas volume, but NaOH had the opposite effect. Apparent dry matter digestion at 6h was lowered by dry heating, NaOH addition and the shorter microwave irradiation. Xylose addition did not substantially change the effects of dry heating, but lowered the initial disappearance. Ammonia concentration was in general lowered by the treatments, suggesting a reduction in protein degradability but also a possible higher microbial uptake for protein synthesis. Microwave irradiation had limited effects on all the parameters. Dry heating, with or without xylose addition, seems interesting to increase rumen escaping protein fraction without accelerating starch fermentation that could expose to higher risks of rumen acidosis. |
