Methane Gas, Cattle Lick and Bone Ash or Calcide Bones

METHANE GAS, CATTLE LICK AND BONE ASH

Methane gas

• The slaughter waste, the ruminal contents, bedding used in the lairage, the dung and other material could be used to produce methane gas in bio gas plants.
• The gas is used for production of heat and light and fetches more prices.

Cattle lick

• Cattle lick is generally prepared from bone meal consisting of:
  • Bone meal : 66 parts
  • Red oxide salt : 33 parts
  • Copper sulphate, Potassium or sodium iodide,
  • Cobalt nitrite, sulphate or chloride or other trace elements : 1 part

Bone ash or calcide bone

• In places where no other option is available, collected bones can be burnt on grills or by trench firing to yield spongy and brittle bones and pieces, which can be ground to ash.
• Being a good source of phosphorus, it serves as a fertilizer.
• In areas where soil is deficient in phosphorus, it enriches the soil resulting in better crop production.
