Meeting the protein requirements of ruminant livestock

  • 1996
  • Issue: 1
  • Volume: 26
D.E. Beever Page: 20 - 26

Ruminant animals acquire their amino acids from the small intestinal digestion of ruminally derived microbial protein and dietary protein which has escaped ruminal degradation. The UK metabolizable protein system provides a framework with which the net absorption of amino acids…

The use of acid detergent insoluble nitrogen to predict digestibility of rumen undegradable protein of heat processed plant prot

  • 1996
  • Issue: 2
  • Volume: 26
G.E. Schroeder, L.J. Erasmus, K-J. Leeuw and H.H. Meissner Page: 49 - 52

The usefulness of acid detergent insoluble nitrogen (ADIN) to predict digestibility of rumen undegradable protein (UDP-D) of heat processed and unprocessed plant proteins was investigated. A series of drum roasted protein sources, sunflower, cottonseed and soybean oilcake meals, in addition…

Ruminal and postruminal digestion of dietary protein and starch in steers: 2. Multivariate model prediction of non-ammonia nitro

  • 1996
  • Issue: 3
  • Volume: 26
H.H. Meissner, D.V. Paulsmeier, K-J. Leeuw and C.M. Coetzer Page: 66 - 74

Multivariate prediction models were developed from the results of three divergent trials with multicannulated steers. Diets differed in composition and physical structure. Energy contents varied from 10 to 13 MJ ME/kg DM, starch from 20 to 62%, CP from 102…
