Minimise risk of acidosis Acidosis more frequently linked to excessive feeding of starchy concentrates. The energy in Prograins Moist feed is predominantly digestible fibre and oil Potential improved rumen function
Easy traceability Prograins Moist feed is produced in the UK and from wheat resulting in a shorter and more local supply chain Peace of mind
Non-GM feeds Prograins Moist feed is made from non-GM wheat Produce livestock products for non-GM fed markets

Feeds Prograins Moist can replace

  • Rapeseed meal - Plus provides extra energy compared to rapeseed meal
  • Imported distillers' feeds - Is more consistent than US maize distillers'
  • Brewers' grains - That are in diminishing supply
  • Forage - Proviso that total ration structure is maintained

Capitalising on Prograins Moist feed will usually increase the amount of low protein energy feeds and forages to balance the protein. Visit the livestock specific pages for details on how this varies for dairy, beef, sheep or young-stock.

Feeding rates

Dairy Milking cows up to 10kg/cow/day
  Dry cows up to 4kg/cow/day
Beef Grower & finisher up to 40% of total dry matter intake
  Stores up to 40% of total dry matter intake
  Suckler cow up to 10kg/cow/day
Youngstock Heifer up to 7.5kg/head/day
  Calf up to 1.5kg/head/day
Sheep Pregnant ewes up to 1.5kg/ewe/day
  Lactating ewes up to 3kg/ewe/day
  Growing lambs up to 2kg/lamb/day
  Store lamb finishers up to 3kg/lamb/day

Suggested feeding rates are produced as a guide only and many other factors may have an overriding effect on animal response; no performance guarantee can be given. Rations should be carefully balanced for energy and protein, contain sufficient forage to maintain rumen function and be fortified with an appropriate vitamin and mineral supplement. Animals must have constant access to clean water.

Feeding systems

Prograins Moist offers a versatile feeding solution and can be used in all types of systems.

  • Simple:
    • Floor or trough feeding
    • Top dressed onto forage mix
  • Mixed rations (mixer wagon or forage box):
    • Full TMR (total mixed rations) and partial TMR
    • Buffer feeding

Complementary feeds

  • Provides a good balance to high-starch feeds - Cereals, maize meals, confectionary and bakery products
  • Complements low-protein forages - Maize & whole crop silages
  • Supplements low-protein feeds - Cereals, Sugar Beet Feed
  • Rumen-bypass proteins - Soypass, Prototec.

Storage & handling

As with all moist feeds, Prograins Moist feed should be stored on a clean surface, air excluded by compressing preferably with a loading shovel, and covered with a sheet. When feeding out only the face should be exposed.

Prograins Moist feed compositionPrograins Moist feed Composition   Back to top

Prograins Moist feed is predominantly a mix of the non-starch fraction of wheat post fermentation of starch to produce ethanol, plus approximately 10% dry weight of dead yeast that grew in the fermentor.  The analysis of the Prograins Moist feed can be divided into 5 fractions as represented in the pie chart. Approximately one third of the product is comprised of protein, with a similar proportion being digestible fibre as represented by the neutral detergent fibre fraction (NDF). The remainder is comprised of the oil, mostly from within the original wheat but now concentrated up three fold, similarly the minerals represented by the small proportion of ash and finally the non structural carbohydrates (NSC) which are comprised of yeast carbohydrates, original wheat carbohydrates of mostly simple sugars and pectins, plus traces of starch.


Based on extensive in vivo studies in the 1980’s and 1990’s on wheat distillers products from the whisky industry undertaken at The Rowett Research Institute (RRI) and ADAS (see below), the metabolisable energy (ME) value of the Moist feed, adjusted for analytical differences is ~ 14.0 ME (MJ/kg dry matter). It is recognised that the soluble fraction of Prograins Moist feed is rich in yeast fragments that are known to stimulate rumen fermentation and leading to higher digestibility and therefore greater energy extraction and hence ME. Many farmers recognise that distillery products ‘feed’ better than their analysis would suggest.

The protein is considered to be one third rumen by-pass. Albeit this is difficult to measure in distillers’ feeds, as the conventional techniques rely on measuring the rate protein is lost from a fine mesh bag and assuming this represents the rumen degradable element. The solubles added back to the ‘fibre’ plus small fibre particles are readily lost from the bag but it is recognised that not all these fractions are highly degradable and probably leave the rumen undegraded only to be digested in the small intestine making a significant contribution to rumen by-pass protein (DUP).

The UK feeding system for ruminants, Feed into Milk (FiM), uses the quantity of acid detergent lignin (ADIN) to estimate the amount of indigestible protein and hence by difference the digestible rumen by-pass protein referred to as DUP. However, it is recognised that for moderately heated proteins such as distillers’ based products this can significantly underestimate the supply of DUP. Hence, adjustments have to be made in the calculation of DUP such as assuming a ~ 85% digestibility for the rumen by-protein as shown in rats fed distillers undegraded protein.

Feeding experiences from a practical and research perspective would suggest that moist wheat distillers, e.g. Vitagold® have a high feed value supporting this assumption.

Digestible fibre

The NDF element of the Prograins Moist feed is paralleled by a low lignin (woody fibre) content indicating a highly digestible fibre component. The absence of any meaningful quantities of starch make Prograins Moist feed an excellent ingredient to reduce the risk of ruminal acidosis.

Despite relatively high NDF content, the effective nature of DDGS fibre for stimulating chewing and rumination is open to question due to small particle size so rations need to be balanced with physical fibre, e.g. chopped forage for improved rumen function. The use of physical fibre in modern dairy rations is now becoming common.


The oil content of distillers, and brewery products, has been associated with lowering the milk fat percentage albeit much practical experience and research does not support this. Milk fat depression is a combination of many factors all of which have to be considered when formulating diets for dairy cattle. Oil in distillers’ products is predominantly unsaturated fat in the same way as that found in grass, grass and maize silages, etc. This type of fat if fed to excess can affect the rumen microbes and products produced from the oil by the rumen microbes can reduce milk fat synthesis in the udder. The context of this is discussed in the dairy feeding section. Similarly any concern with regard to any affect on carcass quality is discussed in the beef and lamb section.


Prograins Moist feed is rich in phosphorus, approximately 1% of dry matter that is vital to the rumen microbes and animals for key functions, e.g. energy metabolism and bone formation.
