Abstract: 

A factorial Experiment was conducted in the laboratories of the Department of Animal Production/College of Agriculture/ Diyala University / Iraq 2015.in which the effect of the mash water temperature with two levels 25 and 40C and mash moisture with two levels 34.7 and 37.0% In a number of physical quality characteristics of feed pellets. The data were analyzed statistically according to a factorial complete randomized design (CRD) with three replications. Pellet broken, unbroken pellet, expansion ratio and dust ratio were measured. The results showed that the temperature of the water was increased from 25 to 40 C the percentage of unbroken pellet significantly increased and the percentage of broken pellet and expansion ratio decreased significantly. While there was no significant effect on dust. The increase in the mash moisture from 34.7 to 37.0 % was significantly increased in the unbroken pellet and the expansion ratio and the significant decrease of the broken pellet. While there was no significant effect on dust. The highest unbroken pellet was 86.42%, the lowest broken pellet was 12.84% between the combination of water temperature of 40 °C and moisture of 37.0%, and the lowest percentage of expansion (swelling) at the rate of 1.01% with water temperature of 25 °C and moisture of 34.7%.                                                                                                            Keywords: mash moisture, broken pellet, expansion pellet ratio, mash temperature.
