Abstract
In this study, the effects of certain feed processing factors on concentrate uniformity and pellet physical quality were investigated. The experimental treatments included the use of new and worn hammers during the grinding process, the addition of 2% sodium bentonite, and the inclusion of 15% and 25% wheat bran in the diet formulation. At the end of the production process, six pellet samples were randomly selected and evaluated for strength. The data were analyzed using SAS software.









The results showed that the passage rates through 16- and 25-mesh sieves were lower in the concentrate pellets ground with new hammers compared with worn hammers, although the differences were not significant \((P>0.05)\). However, passage through the 30-mesh sieve in pellets ground with new hammers was significantly lower \((P
