SUMMARY:

Corn bran is a co-product obtained by the degermination of corn grain, the stage where the husk is removed and the corn germ is extracted, it goes through sieving which is responsible for purifying, reducing and extracting all the bran possible. The present work evaluated the feasibility of using a corn co-product, generated and/or produced in industry (mill), as a final binding agent for pelleted cattle feed. For this purpose, a formulation was selected from the dairy cattle line, pelleted feed with 22% protein, which is the company's flagship product sales. Different levels of corn bran were included in the formulation (5%; 7.5%; 10%; and 12.5%); to evaluate what would best represent a satisfactory level of pellet agglutination and its quality, and observe the effect of transportation on the completeness of the pellet to the rural property. The experiment was carried out on the premises of the feed factory and on rural properties. Samples were collected at three specific points: finished product silo; output scales in bulk; and in the customer's silo, totaling 30 monthly samples, covering 10 months of collection. Although the inclusion of corn bran did not influence the PDI, there was an improvement in the bromatological quality of the feed for fat, crude fiber and phosphorus. The variables hardness, dry matter and humidity were influenced by the feed collection location, and the further from the factory, the lower the humidity, the higher the hardness and DM. This result corroborates the relationship observed between distance from the property and pellet hardness, with the pellet having greater durability in more distant properties. The seasons had an influence on all variables studied, with the best pellet being observed in the summer season due to the highest hardness and PDI values. The inclusion of corn bran did not improve the pelletized quality of the feed.
