AB  - The nutrient composition of six forage types from two zones 
  in Cambodia was compared against faecal and urinary excretion of macro minerals 
  by growing cattle in these regions. The forage types were rice bran, rice straw, 
  para grass, cassava foliage (leaves and petioles), leucaena leaves and water 
  hyacinth leaves. One sample of each forage type was collected from four different 
  sites representing two major agro-ecological zones of Cambodia. Potential mineral 
  deficiency was investigated by analysing the mineral composition of faeces and 
  urine samples collected from 28 non-pregnant, non-lactating cows of the Local 
  Yellow breed, equally distributed between the two zones. The analyses showed 
  that Ca and P levels varied markedly between the different forages. The P concentration 
  in rice bran matched animal requirements but that in rice straw was low and 
  that in cassava foliage, leucaena leaves, para grass and water hyacinth was 
  marginal. The concentration of all minerals in faeces dry matter was slightly 
  higher in one of the two regions. The data obtained on faecal and urinary excretion 
  of minerals indicated that Ca, P, Na and Mg intake was insufficient in the cattle 
  sampled. The results also indicated that several of the commonly used forages 
  in Cambodia have a mineral composition that does not fully cover the requirements 
  of growing cattle. However, it would be possible to meet the requirements by 
  mixing these forages.
