Corn Gluten Feed (CGF)
What is Corn Gluten Feed?
Corn Gluten Feed (CGF) is a by-product of the wet milling process of Maize Grain. CGF is a golden-brown colour, free flowing granular powder, with a pleasant fermented odour. It is similar to previous feeds known as Hominy or Avon. CGF can be included in rations as a source of high energy and medium protein feed, with relatively low starch levels and highly digestible fiber content.
Features & Benefits:
- The CGF protein level, which is higher than maize grain protein, is degraded relatively rapidly in the rumen.
- The small granular size of the feed allows for a high dry matter intake.
- CGF does not appear to depress fiber digestibility, where as corn grain or high starch feeds can lower pasture intake.
- CGF being a balanced product is a good substitute for pasture or silage, and a means of resting paddocks.
- CGF has a higher energy and total digestible nutrient value compared to kibbled maize, with significant amounts of available phosphorus.
- Because CGF is low in nonstructural carbohydrates and starch levels, CGF can be included in feed where acidosis could be an issue. It can also be effective in reducing the potential for acidosis during the critical transition period of 21 days prior to calving.
Feeding Recommendations:
CGF is suitable to feed during any stage of the farm cycle when protein is needed in the diet.
CGF can be utilised in heifer and cow diets without affecting performance negatively. Requirements will depend on your farming system.
Storage:
Like all feedstuffs, CGF should be stored dry, in bulk bins or placed on cement slabs (away from vermin and covered and protected from the weather accordingly) to maintain quality. Moisture contact can cause growth of moulds and toxins.
