Prevention and control

PREVENTION AND CONTROL
  • Restricting the grazing to 20 minutes at a time Prior feeding of dry scabrous hay particularly cereal hay and straw
  • Choice of forages: Seeding cultivated pastures to grass-legume mixtures is the most effective.
  • In a grass- legume mixture a legume content of 50% is suggested as the maximum bloat safe level.
  • High energy and high protein supplement increases the incidence of bloat.
  • Use of condensed tannins (proanthocynanidins) :  @ 5g/kg DM of CT is necessary to prevent bloat

Antifoaming agents

  • Individual drenching: twice daily dose of 60- 120 ml of oil;Method to be adopted if practical utility is observed under field conditions

Application to flanks

  • Types of oil: most vegetable oils, mineral oil and emulsion tallow are effective. Choice depends on availability and cost.  This procedure is followed in foreign countries and may be tried in India if feasible.

Synthetic non-ionic surfactant

  • Polaxalene: surface-active agent polyoxythylene polyoxypropylene block polymer effectively used for prevention of legume pasture @ 2g/100 kg BW.
  • Alcohol ethoxylate detergents: foam-reducing qualities, better palatability. Blocks containing 10% alcohol ethoxylate @ 17-19 g daily consumption.

Feedlot bloat

  • Roughage in ration: feedlot high level grain rations should contain at least 10-15% roughage, which is cut or chopped and mixed into a complete feed.

Dietary salt

  • 4% salt to feedlot has been recommended.
