Canadian Alternatives for Dietary Antibiotics as Growth Promotants

Summary: Although feed antibiotics have aided in production there is movement to reduce and eliminate the use of antibiotics in feed due to various risks. These risks include risks to human health. As a result a plethora of products have been produced to replace antibiotic use, all of which have varying degrees of effectiveness.

Canadian alternatives that have been developed include:

  • Egg yolk antibiotics
  • Raw potato starch
  • Pre- and probiotics
  • Organic acids
  • Feed enzymes
  • Lysozyme
  • Plant extracts (phytogenics)
  • Use of low crude protein diets

Egg yolk antibiotics: Egg yolk antibiotics are produced in response to a specific antigen. There is variability in effectiveness, which is a result of many factors such as low gut pH and breakdown from pepsin digestion.

Raw potato starch: Studies have displayed raw potato starch to have potential to be an alternative to antibiotics in piglets to control post-weaning diarrhea.

Pre- and probiotics: Have been displayed to positively influence growth performance, nutrient digestibility, immunity, intestinal, fecal microbiota and diarrhea score in pigs.

Organic Acids: Through studies organic acids have been shown to be effective. They have become accepted alternatives to antibiotics as growth promoters in swine. They inhibit gut infections and improve the population of beneficial bacterial. They also improve nutrient digestibility and growth performance.

Feed Enzymes: Enzyme breakdown products have been displayed to maintain gut barrier function during the presence of an E.coli infection. They contribute to robust pigs through possibly eliminating dietary compound and anti nutritional factors which interfere with nutrient utilization.

Lysozyme: In an antibiotic free diet, lysozyme has displayed positive indicators of gut health, resulting in a decreased population of pathogenic bacteria.

Plant Extracts: Beneficial effects include: improvement of growth parameters, immunity and gut microbial balance in swine. There has been limited studies revolving around the implications of medicinal effects of plants in animal diets, however the studies completed do have positive outcomes.
