Energy Sources.. Nutrition

There are 4 types of energy sources used in poultry and livestock feeding;
  • Cereals (Maize, Sorghum, Wheat, Rice and Millets)
  • Cereal Byproducts (wheat bran, rice bran, maize bran and rice polishing etc)
  • Industrial Waste (Molasses)
  • Fats and Oils (animal and vegetable oils)
Maize:
  • It is principle energy source for poultry.
  • It contains highest amount of energy among cereal Grains.
  • M.E = 3340-3400 kcal/kg.
  • C.P = 9.8%
  • Whenever maize is stored, moisture level should be low to avoid fungal attack. So, aflatoxins are its restriction. Moisture level should be 12-15%.
  • Highly palatable and excellent source of linoleic acid. Xanthophylls are higher in yellow maize.
  • Inclusion rate = 10-50%.
By-Products
Maize bran is also excellent source of linoleic acid having C.P 10%. It is mostly used for buffalo feed. Energy value is 1300kcal/kg.
Wheat:
  • Good source of energy next to maize and sorghum.
  • M.E = 3400-3500 kcal/kg. Variable protein is 11-14%.
  • It is principally used for humans.
By-Products
  • Wheat bran is the coarse outer covering of wheat kernel separated from wheat during milling.
  • M.E = 1300 kcal/kg
  • C.P = 15%.
  • It is laxative in nature due to high fiber content.
Rice:
  • M.E = 3200 kcal/kg
  • C.P = 8-10%.
  • Narowal Rice is famous
By-Products
  • These include rice bran, rice polishing, rice tips and rice broken (totta).
  • High oil contents (17%) in rice polishing.
  • Low oil contents (1-2%) in rice bran.
  • Rice tips and rice polishing have C.P = 8% and M.E = 3400-3500kcal/kg.
  • Inclusion Rate = 20-50% for rice tips and 10-15% for rice polish.
Sorghum:
  • Also called milo or jowar
  • M.E = 3350 kcal/kg.
  • Higher protein than maize (10%)
  • Light and dark varieties
  • Availability of amino acids is low.
  • Tennins is its restriction which is removed by alkalis.
  • Inclusion rate = 5-10%.
Millets:
  • Also called Bajra. These are small grains.
  • Can be used in substitution of wheat.
  • M.E = 2898 kcal/kg.
  • C.P = 11.6%.
  • Inclusion rate = 30-60%.
Molasses:
  • It is a by product of the sugar refining industry.
  • Both can and beet molasses contain 46-48% sugar.
  • Increase palatability and decrease dutiness of feed.
  • C.P  = 3%.
  • M.E = 1962kcal/kg.
  • Inclusion rate = less than 5%.
  • Very high potassium content is its restriction.
