Technical Detail


Many research reports indicate that the degradation of nutrients in the rumen does not deliver the correct balance of essential amino acids at the small intestine for absorption. The Protein meal has variable degree of naturally rumen-protected protein. Degradation of such protein in the rumen is usually more than 70 % and lead to their insufficient utilization
Giving chemical treatment to the protein meal has been one of the established and economical methods of producing rumen-protected protein which ensures 70-75 % of the rumen protein protection. Protected protein by passes the rumen and provides essential amino protein for the absorption in the small intestine.

The feeding of by pass protein feed can earn 10-15 % more money as indicated by various feeding trials. The by pass protein feed plant has been established at Khandia (Ta: Shehra) with the technical help of NDDB and Australian Center for International Agricultural Research (ACIAR) in December 2006 with production capacity of 10 MTPD.

The advantages of bypass protein feed:

  • Alter the ratio of RDP/UDP in the diet and increase quantity of metabolizable protein
  • Increase the supply of limiting amino acids like lysine and methionine
  • Higher availability of amino acid per unit of feed
  • Excessive loss of both nitrogen and energy could be avoided,
  • Judicious utilization of protein meals available in limited quantity
  • Improves growth rate and milk production (0.8-1.2 liter/day)
  • Improves protein % (0.1-0.3%) in milk, hence improves SNF content of milk.
  • Better economic return, for the same input cost.
  • Requirement of high yielding animals can be met with lesser quantity of feed
  • Increase keeping quality by preventing from Salmonella and yeast fermentation
