Swine nutrition

Feeding strategies

Ingredient quality

  • Mycotoxins harm swine health and reproductive performance — Some fungi molds in grain can produce harmful compounds called mycotoxins. Pigs consuming mycotoxins above their tolerance level will face health and reproductive problems. Submitting samples of contaminated feeds to a lab can help you manage your feeding practices and prevent mycotoxin toxicity in your pigs.
  • Mixing your own swine feed — Monitoring feed quality from purchase to when the pigs eat it is key to successful pork production, including quality control when mixing swine feed.

Alternative ingredients

  • Feeding value and energy prediction of DDGS with differing oil content  — The oil content of corn distillers dried grains with solubles (DDGS) doesn’t affect growth performance and carcass traits of grow-finish pigs if the sources have similar metabolizable energy (ME) content. Reducing the oil content of DDGS improves pork fat quality.
  • Using crude glycerol in sow dietsIncluding up to 9 percent crude glycerol in lactating sow diets likely doesn’t affect sow performance compared to a typical corn-soybean meal diet.
  • Using microalgae in swine diets   — With more research, microalgae can change the sustainability of animal and food production systems. Their rapid growth and nutritional content may be valuable for use in swine diets in the future. Microalgae could be an alternative feed ingredient that helps support growing populations
