Animal production sector is the main source of animal protein represented in red meat production, which amounted to about 941 thousand tons in 2014, Self-sufficiency ratio was about 72% of the same year. The stage of animal slaughter did not receive sufficient attention so far, both from research or government organization in spite of its importance. The numbers of slaughterhouses in Egypt are 474, and only four slaughterhouses exist in Alexandria.
