Method for producing an extruded feed containing fibres

A process to obtain extruded animal feed, the process consisting of the following steps:

• treating a harvested sorghum dry straw with an antifungal including ammonium dipropionate;
• pre-milling the harvested sorghum dry straw from the previous step to a particle size of 5-10 cm;
• milling the pre-milled treated harvested sorghum dry straw from the previous step to a particle size lower than 6 mm;
• milling sugar cane as a fiber source to a particle size lower than 6 mm;
• preparing a dry mixture by mixing:
• wherein the dry mixture consisting of:
• the milled treated harvested sorghum dry straw, 40-70% by weight;
• at least one of sunflower bran and cotton bran, 1-4% by weight;
• and
• the milled sugar cane, as the fiber source, 15-50% by weight;
• weighing the mixture to a pre-set weight;
• adding to the dry mixture:
• urea 0.01-3% by weight, and
• at least one of potassium chloride, limestone, calcium sulfate, dicalcium phosphate, potassium, monensin, virginiamycin, yeast, white salt, molasses, powdered milk, or ready formulations under the ratio of 0.2-6% by weight;
• milling the dry mixture from the previous step in a hammer mill having a 1.5-2.0 mm screen;
• steaming and pressure cooking the mixture of the previous step;
• extruding the mixture of the previous step;
• determining a particle size of the extruded mixture;
• drying the extruded mixture of the previous step until a humidity between 4% and 12%;
• and
• cooling the mixture of the previous step with cold air jets.
