Abstract

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 (n = 14) received orally 1.5 ml EOB/d and control (n = 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 (p < 0.05) milk yield, ECM, and NEL than control. Treated does had higher (p = 0.02) energy balance than control does. The EOB increased (p < 0.05) concentrations of serum albumin, cholesterol, triglycerides, and IgG. Treatment with EOB improved (p < 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.

摘要

研究了肉桂、百里香和薄荷精油混合物 (EOB) 对泌乳早期母牛产奶量、血清成分和能量平衡及其孩子表现的影响。将 27 只晚期怀孕的大马士革山羊分为两组：EOB（n  = 14）口服 1.5 ml EOB/d 和对照（n = 13) 每天口服 1.5 毫升水。该追踪在预计开玩笑日期前 15 天开始，持续了产后 30 天，同时样本收集一直持续到哺乳期第八周。在产后连续 8 周内监测产奶量和成分、母体代谢特征、免疫球蛋白 (IgG) 和孩子的体重。估算能量校正牛奶 (ECM)、牛奶能量值 (MEV)、泌乳净能 (NEL) 和能量平衡。用 EOB 处理的 奶产量、ECM 和 NEL 比对照高 ( p < 0.05)。治疗组确实比对照组具有更高的 ( p  = 0.02) 能量平衡。EOB 增加了 ( p  < 0.05) 血清白蛋白、胆固醇、甘油三酯和 IgG 的浓度。EOB治疗改善（p  < 0.05) 独生子女的断奶体重和总体重增加。在过渡期给予 EOB 45 天可以改善山羊的产奶量、代谢状态和能量平衡以及山羊的生产性能。
