Impact of specific essential oils blend on milk production, serum biochemical parameters and kid performance of goats.

Effects of cinnamon, thyme, and peppermint essential oils blend (EOB) on milk production, serum constituents, and energy balance of early lactating does and performance of their kids were investigated. Twenty-seven late pregnant Damascus goats were grouped into two treatments: EOB ( = 14) received orally 1.5 ml EOB/d and control ( = 13) received orally 1.5 ml water/d. The trail started 15 days before the expected kidding date and lasted for 30 days postpartum while sample collection continued until the eighth week of lactation. Milk yield and composition, maternal metabolic profile, immunoglobulin (IgG), and weights of kids were monitored throughout 8 consecutive weeks postpartum. Energy corrected milk (ECM), milk energy value (MEV), net energy for lactation (NEL), and energy balance were estimated. Does treated with EOB had higher ( < 0.05) milk yield, ECM, and NEL than control. Treated does had higher ( = 0.02) energy balance than control does. The EOB increased ( < 0.05) concentrations of serum albumin, cholesterol, triglycerides, and IgG. Treatment with EOB improved ( < 0.05) weaning weight and total weight gain of single kids. Administration of EOB for 45 days during the transition period could improve milk production, metabolic status and energy balance of goats and performance of kids.
