The experiment was conducted in male Desert goats to study the effect of dietary protein levels and castration on primal cuts, meat quality and non-carcass components of male Desert goats. Twenty-four male Desert goats aged 4 - 5 months and weighing 10 Kg were used in this study. The goats were divided into three groups of similar age and weight (8 males), and every group was subdivided into two subgroups; (4 males) one subgroup was castrated (by using burrito) and the other was left intact. Group one was adlibitum fed on the diet (A) (23% crude protein), group two was adlibitum fed on diet (B) (20% crude protein) and the third group was adlibitum fed on diet (C) (18% crude protein) in factorial experiment randomized complete design and the data was analyzed by Statistics 8 program. The results revealed that protein levels, castration and interaction had no significant (P ＞ 0.05) effect on primal cuts. Protein levels and castration had no significant (P ＞ 0.05) effect on flavor and tenderness except juiciness, protein levels and castration had no significant (P ＞ 0.05) effect on non-carcass components. The interaction had no significant effect (P ＞ 0.05) on non-carcass components except forefeet and head. It could be concluded that the 20% crude protein had achieved relatively higher forequarter and rack % and had a significant (P ＜ 0.01) on meat juiciness score.
