Independent research into the efficiency
of feeding crimped moist grain |
1: Rumen degradation
Reading University: Investigation into rumen degradation of crimped wheat. A report prepared by Dr Fergus Mould comparing the rate of gas release using samples of crimped wheat ensiled with Kemira Crimpstore 2000S, dry rolled wheat (screened to fine, medium and coarse) and caustic treated wheat (treated at various weights per tonne). Results show that both initial fermentation was higher and subsequent degradation remained longer in the rumen with crimped wheat.
Summary or full report available. |

2: LWG of young bulls
Comparison of daily liveweight gains of young bulls fed with Crimpstore 2000S treated crimped barely based rations, alternating with dry rolled barely based rations. The feed values of each ration
were equalised on a DM basis.
Conclusion: daily lwg increased by an average of 6.9% with Crimpstore 2000S treated crimped grain. Source: SIGRA (Latvia University Agricultural Research Centre

FEED CONVERSION
The table below shows the feed conversion efficiency for each month's feeding.
The overall effect is that feed consumption for 1kg lwg increased by 11.2% on dry rolled barley while digestible protein increased by 10

3: Feed conversion, fattening bulls
Comparison of lwg in fattening bulls on either dry rolled barley or Crimpstore 2000S treated crimped barley based rations. The feed values of each ration have been equalised on DM basis. 90 day trial. Average liveweight gain increased by 15.5% on Crimpstore 2000S treated crimped barley based diet.

This table shows that cattle are more efficient in converting rations based on crimped barley than dry rolled. The same applies to digestible protein. To achieve a 1kg lwg fattening bulls need to eat 12.8% more of dry rolled barley than crimped.
The figure for digestible protein on the same basis is 17.1% more of dry rolled barley diet.

5:Pigs
In Finland pigs have been fed crimped grain for many years. In the UK some commercial breeders have just started and early results are most encouraging.
