Bypass Protein Supplement
Dairy animals have four compartments in its stomach. The first and the foremost is ‘rumen’ where most of the feed items are degraded. Around 60 to 70 per cent of dietary protein meals fed to animals are degraded to ammonia in the rumen. A significant part of this ammonia is excreted through urine in the form of urea. Thus, a large portion of protein from expensive cakes/ meals is wasted. If suitable treatment is given to dietary protein meals, degradation in the rumen can be minimised. This process or treatment to protect dietary protein from degradation in rumen is known as bypass protein technology. These protected meals are digested more efficiently in the small intestine and results in extra protein being available for milk production. This helps the animal to produce more milk and of optimum quality.
NDDB has standardised and commercialised bypass protein technology, using locally available protein meals such as rapeseed meal, sunflower meal, groundnut meal, guar meal and soybean meal. These protein meals are treated suitably to reduce their degradability in the rumen from 60-70 per cent to 25-30 per cent, in a specially designed airtight plant. Treated protein meal can be either fed directly to animals as top feed @ one kg per animal per day or can be incorporated in cattle feed @ 25 per cent and this cattle feed can be fed @ 4-5 kg per animal per day, depending up on the level of milk production. Cost of treatment of protein meals is ₹ 2.5 to 3.0 per kg but considering the resulted increase in milk yield it is always cost effective.
Technical assistance in setting up bypass protein plants is provided to dairy cooperatives and other agencies, for the production of bypass protein supplement/feed.
