This study was conducted to compare the effect of different ratio of
omega-3:omega-6 in total mix ration to blood metabolites and reproductive
performance of ewes. A total of 25 young ewes were randomly assigned to five
experimental groups and five replications : R0 (without omega-3:omega-6), R1
(omega-3:omega-6 1:8), R2 (omega-3:omega-6 1:6), R3 (omega-3:omega-6 1:3), R4
(omega-3:omega-6 1:2). The parameters measured were feed intake, productive
performance, blood glucose and cholesterol pre-mating period. Parameters of
characteristic estrous measured were onset of estrous, length of estrous and
estrous response. The result showed that ratio of omega-3 and omega-6 1:2 have a
greatest daily weight gain and feed efficiency. Ratio of omega-3 and omega-6 1:2
have blood glucose lowest, but highest blood cholesterol. Addition of omega-3
cause to delays onset of estrous. The conclusion is greatest length of estrous,
estrous response and pregnacy rate on ratio of omega-3 and omega-6 1:2 in ration
