This study aimed to investigate the impact of feeding by different corn silage (CS) proportions on ewes milk yield and fatty acids composition. Twenty-one lactating Assaf were divided into 3 groups (7 each). The following dietary treatments based increasing proportion CS in total mixed ratio (TMR) tested; (1) 47 % AH (0 TMR) correspond 0 CS, (2) 23.5 (23.5 50 (3) (47 100 CS. After 8 weeks feeding, type diet had no significant effect solid; however, it significantly affects fat. levels C8:0 C14:0 not affected levels. While C10:0 C12:0 increased when fed a diet. However, lower level C16:0 (33.22 %) was observed compared at (40.66 37.98 %, respectively). Similar trend for C18:0, lowest with diets (7.52, 12.69, 10.61 100, 50, Total USFA decreased (p < 0.05) feeding. It can be concluded that replacement alfalfa some influence composition, especially profile.
 HIGHLIGHTS
 
 Utilization nonconventional feed ingredients is important reduced cost improving its nutritive value
 Milk profile replaced portions silage
 More research needed confirm our findings
