主 题：feeding rate fineness degree broiler diets pellet quality production cost
摘 要：The effect of a machine feeding rate(FR;1,1.5 and 2 Mg/h)and/or three levels of selected fineness degree(FD;3,5 and 7 mm)on machine performance,pellet physical parameters,required energy and production cost of three main types of broilers diets were examined in this *** examined broiler diets were formulated to meet the Ross 308 strain requirements.A complete factorial design(3×3×3)was used to identify the effects of studied factors on the pellet mill machine and pellet *** obtained results indicated that the pellet mill productivity significantly(p˂0.001)improved through increased pellet mill feeding rate *** addition,the machine pelleting efficiency was found to be significantly affected by all studied variables and their *** the total power consumption of the machine showed no variations under the impact of the tested factors or with any of their *** the pellet physical quality indices,all broiler diets with all selected FD and lower FR had the maximum durability and bulk density ***,lower feeding rates were associated with higher hardness *** lowest production costs were substantially correlated with high FR and intermediate FD(5 mm).Furthermore,production costs were determined to be reduced in finisher broiler diets under different feeding ***,manufacturing costs of finisher broiler meals were observed to decrease in several feeding ***,these findings indicate the capabilities of producing high-quality pellets and reducing the needed production costs by optimizing feeding rates to 2 Mg/h and 2 mm fineness in broiler diets.
