The research aimed to study the productive and economic efficiency of the red meat production sector within the farms of North Sinai Governorate Egypt. The results showed that the total costs per head of fattening cows amounted to about L.E 18169.9, which is equivalent to about L.E 45 per kg of live weight meat of beef, compared to about L.E 18302.6 for a head of fattening buffalo, equivalent to about L.E 42.3 per kg of live weight of buffalo meat, at the level of the total sample farms during the 2021 fattening season. With regard to the profit margins of cows, it was found that the net return and the added value of the fattened head of cows swallowed each are about L.E 6164.6, 7944.5, respectively, equivalent to about L.E 15.3 and 19.7 per kg of live weight meat of beef, compared to about L.E 6298.4 ,7996.9 respectively, equivalent to about L.E 14.6 and 18.5 per kg of live weight of buffalo meat, at the level of Total sample farms during the 2021 fattening season. By examining the indicators of productive efficiency for fattening cows and buffaloes, it was found that the production elasticity of the concentrated fodder component, dry fodder, fresh fodder, and human labor amounted to about 0.476, 0.332, 0.218, 0.132 for cows, respectively, compared to about 0.534, 0.367, 0.212, 0.186 for buffaloes in the same order. The research recommends increasing the used quantities of production elements combined and re-mixing them with each other in order to achieve optimal use of them.
