Effect of essential oil blends and a nonionic surfactant on rumen fermentation, anti-oxidative status, and growth performance of lambs.

ABSTRACT: This study aimed to evaluate the effect of essential oils (OEO; XEO) and an emulsifier on rumen fermentation, anti-oxidative status, and the growth performance of lambs. A finishing study was conducted using 35 females and 35 males Suffolk × Canadian Arcott crossbreed lambs, fed a 16:84 forage:concentrate pelleted barley-based with either Control; Bovatec (0.018% Bovatec); Emulsifier (0.25% of Emulsifier); OEO (0.11% of blend 1); XEO (0.0125% of blend 2); OEO + Emulsifier; or XEO + Emulsifier. The rumen fluid of all lambs was sampled via stomach tubing to measure ruminal pH, volatile fatty acid (VFA), and NH₃ concentrations and enumerate protozoa. Ruminal pH, molar proportions of individual VFA (except for acetate), and ammonia concentration were similar among treatments. The ac
