Crude coriander oil in the diet of lactating goats enhanced lactational performance, ruminal fermentation, apparent nutrient digestibility, and blood chemistry

Abstract The use of safe feed additives in diets of lactating animals has gained increasing interest. The effects of feeding lactating goats on diet supplemented with crude coriander oil at different levels were evaluated. Thirty multiparous lactating Damascus × Baladi goats (27.2 ± 1.0 kg BW) were used in 3 × 3 Latin square design (3 treatments, 3 periods, and 10 does per treatment). Each experimental period lasted 30 d (comprising 20 d of treatments adaptation and 10 d of sampling). The treatments consisted of the control basal diet with no crude coriander oil, the control basal diet supplemented daily with 0.95 g crude coriander oil/kg DM feed, or the control basal diet supplemented with 1.9 g crude coriander oil/kg DM feed. Crude coriander oil supplementation linearly increased (P
