This study aimed to evaluate the impact of thyme and/or garlic oil administration on growth
performance, immunity, antioxidant, biochemical parameters, and net farm income of Damascus
goats. Forty weaned Damascus goats were allocated into four groups. The first group was the
control without oral administration, while the 2nd (Th), 3rd (Gr), and 4th (ThGr) groups were orally
administrated by (2 ml/goat/day) of thyme oil, garlic oil and their mixture (1:1), respectively during
the whole experiment period. The final body weight of goats orally administered oil mixture was the
heaviest group, it was 10, 4.5 and 3.5% than the control, Th. and Gr. groups, respectively with better
feed conversion ratio and high net farm income. Goats of ThGr. group revealed the best immunity,
antioxidant and general health condition than the control group with 50% reduction of MDA. Liver
(AST, 33% and ALT, 38%) and kidney (creatinine, 88%) functions improved by oils mixtures orally
administration compared with the control group. LDL, triglyceride and cholesterol were reduced
by 47, 33 and 21% compared with the control group, respectively. Thus, mixture oil administration
(thyme and garlic at the ratio of 1:1, 2 ml/goat/day) improved growth (10%), antioxidant status (MDA
50%), liver (AST, 33% and ALT, 38%), kidney function (creatinine, 88%), the FCR (17.4%) and net farm
income (21%), of Damascus goats.
