Dietary supplementation under high ambient temperatures can be considered crucial for supporting immune responses in livestock. In the present paper, essential oil (REO) alone and in combination with dried sugar beet pulp (REO + B) was included in the diet of lambs during the fattening period under heat stress conditions. Environmental conditions and physiological and growth parameters of lambs were monitored throughout the trial. Plasma samples were collected to evaluate cytokine secretion (IL-1β, IL-6, and IL-10). Notably, REO inclusion reduced rectal temperature and respiration rate while increasing pro-inflammatory cytokines (IL-1β and IL-6) at the same time, suggesting an enhanced immune response without compromising growth performance.
在高温环境下进行膳食补充被认为对支持家畜的免疫反应至关重要。在本文中，在热应激条件下的育肥期，单独的精油（REO）以及与干甜菜粕混合的精油（REO + B）被添加到羔羊的日粮中。在整个试验过程中监测羔羊的环境条件、生理和生长参数。采集血浆样本以评估细胞因子分泌（IL-1β、IL-6和IL-10）。值得注意的是，添加REO可降低直肠温度和呼吸频率，同时增加促炎细胞因子（IL-1β和IL-6），这表明在不影响生长性能的情况下免疫反应得到增强。
