    Rye in the feed

Hybrid rye—a high quality feed!

By using rye in your feed, you contribute to animal welfare and animal health with high performance. The DLG recommends up to 50% rye in pig fattening and up to 4 kg per day or 40% in concentrated feed in dairy cattle feeding.

What does rye offer in feeding?

  • High energy content (MJ) per hectare
  • High lysine content in the crude protein
  • Butyrate—from rye—contributes to salmonella reduction
  • Butyrate—from rye—lowers skatole-induced boar odour
  • Product safety due to low Fusarium susceptibility
  • Reduced ergot risk through PollenPlus® technology

Crop Benefits

  • Low production costs
  • High nitrogen efficiency (kg N per 100 kg of grain)
  • Highest yield potential of all grains

Keyadvantages for monogastric feed-pigs

Unique characteristics of rye grain

  • Higher lysine:protein ratio in comparison to other cereals
  • Low Glycemic Index (GI) and high satiety
  • Decreased gut ulceration from a higher dietary fibre content
  • High levels of occupation [chewing] and less boredom
  • Increased welfare and reduced stress (nipping, bruising, mounting etc..)

Rye supports a very high fructane content

  • Fructan is a structural component of all cereal grains, however rye has the highest fructane content amongst all cereal species
  • Fructan is digested in monogastics via the hind gut
  • is subsequently converted to butyrate
  • In pigs this has the potential to limit skatol release (a contributing factor in boar taint and low consumer acceptability)
  • Additionally a lower risk of salmonella (via the higher absorption of butyrate) from high fibre diets using rye

Rye inclusion recommendations (LW basis and % Rye inclusion)

  • Fattening pigs: (28- 40 kg) 30% Rye, (40 – 60 kg) 40% Rye, (60 kg) + 50% Rye
  • Sows: 25%Rye
  • Piglets: (15 kg +)– 10 - 20% Rye

Agronomic advantages of hybrid rye

  • Extreme winter hardiness and frost resistance
  • Aggressive tillering capacity
  • Drought tolerance – ideal for sandy soils
  • Blackgrass suppression – via light reduction in the canopy
  • Extends crop rotation
  • Very high take-all tolerance – ideal as a second cereal
  • Minimal ergot risk – via PollenPlus®

Two-thirds of the German rye harvest is used for feeding—rely on proven and regional feed!
