Key advantages 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

Key advantages for Rye for ruminant feed - cattle:

  • The lower protein content of rye compared to wheat and triticale make it suitable both for maize silage-based, starch-rich rations as well as for protein-rich rations with a high volume of grass and leguminous crops
  • TMR (Total Mix Ration) systems for dairy nutrition also offers the possibility of directly mixing in rye, preferably in crushed / crimped form
  • Rye for beef finishing can safely supplement wheat depending on the target LGW, and acts as a cost-effective concentrated feed grain in beef cattle rations

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 PollenPlusģ
