The determination of the energy consumption in manufacturing different type of feeds, rabbit, poultry and large animal feeds (pellets and crushed), was the main aim of this study. This was achieved by determining the energy consumed in each stage of processing to assess the most consumable stage in the different types of feed. The results indicated that the total specific energy consumed were 243.55, 217.25 and 100.67 kJ/kg for rabbits, poultry and large animals feed pellets, respectively. The crushed feed processing consumed less energy where, it was 30.70 and 30.82 kJ/kg for large animals and poultry, respectively. In comparison between the specific energy consumption of different types of feeds, it could be concluded that to produce one kg of rabbit feed pellets consumed energy as 2.43 times as of large animals feed pellets and 8 times as of the energy consumed of crushed feed of large animals. It is worth to mention that pelletizing process was the most consumable stage of feed manufacturing, where, it consumed 80.76, 83.26 and 64.36% of the total energy consumed of rabbits, poultry and large animals feed pellets, respectively. |
