Implication

Controlled feeding trial reveals that enzymatically-modified canola meal enhances nutrient digestibility and gut microbiota in broiler chickens, indicating its potential as a functional feed.

Key Points

  • Evaluate the effects of enzymatically-modified canola meal on growth performance, nutrient utilization, and gut health and function in broiler chickens.
  • Assigned 320 Ross 308 broilers (4-day-old, as-hatched) across 5 dietary treatments in 8 cages of 8 birds per treatment.
  • Fed starter (days 4–14) and grower (days 14–21) diets consisting of a standard canola meal control, low or high enzymatically-modified canola meal substitution, or direct multi-carbohydrase enzyme supplementation.
  • Replacing standard canola meal with modified meal did not affect growth performance, but significantly increased apparent total tract non-starch polysaccharide digestibility and nitrogen-corrected apparent metabolizable energy.
  • Diets containing enzymatically-modified canola meal significantly increased Lactobacillus abundance in both the ileum and ceca (P < 0.01) throughout the trial and reduced day 21 sialic acid secretion compared to control and enzyme diets.
  • High substitution with enzymatically-modified canola meal significantly lowered cecal Escherichia coli in the grower phase and increased cecal short-chain fatty acids in the starter phase compared to the control.
