## Abstract

A process for obtaining extruded animal feed including fibers, especially sugar cane and corn straws, applied in the agricultural and cattle-raising field for the nutrition of ruminants, contributing for higher productive performance (meat or milk) than conventional animal feeds, making use of the non-used sources of fibers for that purpose, with extruded characteristics, as well as for equines, wherein the process follows exactly the same procedure as shown by the patent application, but without the mixture of urea and additives.

## Claims

### Claim 1

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.
