Abstract:The objective of this study was to evaluate the effects of dietary oregano essential oil on growth performance, slaughter performance and meat quality of sheep. Eighteen 3-month-old healthy crossbred (Suffolk×small tail Han sheep) male lambs with similar body weight of (20.30±1.27) kg were randomly divided into 3 groups with 6 lambs per group. Sheep in the control group (CON group) were fed a basal diet without oregano essential oil, and those in the oregano essential oil group were fed the basal diet supplementation with 4 (EO4 group) or 7 g/d (EO7 group) oregano essential oil. The experiment lasted for 72 days after 10 days adaption. The results showed that average daily feed intake in EO4 and EO7 groups was significantly higher than that in CON group (P<0.05). The average daily gain in EO7 group was significantly higher than that in CON group (P<0.05), while the feed/gain was significantly lower than that in CON group (P<0.05). The live weight, carcass weight and slaughter rate in EO7 group were significantly higher than those in CON and EO4 groups (P<0.05). The gross profit in EO4 and EO7 groups was improved 2.0% and 0.2% compared with CON group, respectively. The pH of semitendinosus and bicep in EO7 group was significantly lower than that in CON group (P<0.05). The shear force of the Longgissmus dorsi and semitendinosus in EO7 group was significantly lower than that in CON group (P<0.05). The results indicate that adding essential oil in the diet of sheep can increase growth performance and slaughter performance, and improve the meat quality. Therein, supplementation with 7 g/d oregano essential oil show a better improvement on growth performance, however, supplementation with 4 g/d oregano essential oil show a better economic benefit. In conclusion, 4 g/d of oregano essential oil is the best choice in sheep production.
