为探讨马酚对肉仔鸡生长和肉质的长期影响，在7日龄受精卵中分别注射0μg(对照组)、2 0μg(低剂量L)和10 0μg(高剂量H)Eq(每组14 6枚)。孵化后，在相同条件下饲养，在49日龄时屠宰，进行样品采集和分析。结果表明，EQ对小鼠的体重和成分影响不大(P>；0.05)。与雄鸡相比，雌鸡服用EQ后对肉质的影响较大。L组和H组母鸡肉色红度(a*)分别显著降低24.10%和21.50%(P<0.05)。L组和H组胸肌T-SOD值分别提高了23.14%和18.82%(P<；0.05)。H组胸肌GSHPx有升高趋势(P=0.06&0.1)。这些结果表明，卵内注射EQ对肉仔鸡的生长发育没有影响，但显著提高了肌肉的保水能力，尤其是对雌性肉鸡，这与其抗氧化状态的改善有关。
In order to investigate the long-term effects of equol (Eq) on growth and meat quality in broilers, 0 μg (control, Con), 20 μg (low dose, L) and 100 μg (high dose, H) Eq, respectively, were injected into fertile eggs (146 eggs per group) on 7 days of embryos. After hatch, chickens were fed under the same conditions and slaughtered at 49 days of age for sample collection and analysis. The results showed that body weight and composition were marginally affected by Eq administration (P > 0.05). Compared with their male counterparts, the meat quality of female broilers was affected greatly after Eq administration. The redness (a*) of meat color in the L and H groups of female broilers was significantly decreased by 24.10% and 21.50% (P 0.05). The T-SOD activity in the breast muscle of the L and H groups were significantly improved by 23.14% and 18.82% (P < 0.05), respectively. GSHPx in the breast muscle of the H group showed a tendency to increase (P = 0.06 < 0.1). These results indicate that Eq injection in ovo does not affect the growth of broilers, but significantly improves the water-holding capacity of the muscle, especially in female broilers, which is related to the improvement of antioxidative status.
