The present study was performed to investigate the effects of dietary supplementation with herbal additives on meat quality, slaughter performance and the cecal microbial community in Hungarian white geese. A total of 60 newborn geese were assigned equally into the control group (CON) and the herbal complex supplemented group (HS). The dietary supplementations consisted of Compound Herbal Additive A (CHAA) including and , and Compound Herbal Additive B (CHAB) containing and . The geese in the HS group received a basal diet supplemented with 0.2% CHAA from day 0 to day 42 at the postnatal stage. Then from day 43 to day 70, the geese in HS group were provide a basal diet with 0.15% CHAB. The geese in the CON group were only provided with the basal diet. The results showed that the slaughter rate (SR), half chamber rates (HCR), eviscerated rate (ER) and breast muscle rate (BMR) in the HS group tended to increase slightly compared with the CON group (ns). In addition, the shear force, filtration rate and pH value of breast muscle and thigh muscle in the HS group were slightly enhanced compared to the CON group (ns). Significant increased levels in carbohydrate content, fat content and energy ( < 0.01) and significant decreased levels in cholesterol content ( < 0.01) were observed in the muscle of the HS group. The total amino acid (Glu, Lys, Thr and Asp) content in the muscle increased in HS group than in the CON group ( < 0.01). Dietary herb supplementations significantly increased the levels of IgG in serum ( < 0.05) on day 43 and higher levels of IgM, IgA and IgG ( < 0.01) were also observed in the HS group on day 70. Furthermore, 16S rRNA sequencing results indicated that herbal additives increased the growth of beneficial bacteria and inhibited the proliferation of harmful bacteria in the geese caecum. Altogether, these results offer crucial insights into the potential benefits of incorporating CHAA and CHAB into the diets of Hungarian white goose. The findings indicate that such supplementations could significantly improve meat quality, regulate the immune system and shape the intestinal microbiota composition.
本研究旨在探讨饲粮中添加中草药添加剂对匈牙利白鹅肉质、屠宰性能和盲肠微生物群落的影响。共 60 只新生鹅被平均分配到对照组（CON）和中草药复合添加剂组（HS）。饲粮补充物包括包含 和 的复方中草药添加剂 A（CHAA），以及含有 和 的复方中草药添加剂 B（CHAB）。HS 组的鹅从出生后第 0 天到第 42 天接受基础饲粮中添加 0.2%CHAA 的饲粮，然后从第 43 天到第 70 天，HS 组的鹅接受基础饲粮中添加 0.15%CHAB 的饲粮。CON 组的鹅仅接受基础饲粮。结果表明，与 CON 组相比，HS 组的屠宰率（SR）、半腔率（HCR）、屠体率（ER）和胸肌率（BMR）略有增加（ns）。此外，HS 组的胸肌和腿肌的剪切力、过滤率和 pH 值略高于 CON 组（ns）。HS 组肌肉中的碳水化合物含量、脂肪含量和能量显著增加（<0.01），胆固醇含量显著降低（<0.01）。HS 组肌肉中的总氨基酸（Glu、Lys、Thr 和 Asp）含量高于 CON 组（<0.01）。饲粮中草药添加剂在第 43 天显著提高了血清 IgG 水平（<0.05），第 70 天 HS 组血清 IgM、IgA 和 IgG 水平也显著升高（<0.01）。此外，16S rRNA 测序结果表明，中草药添加剂增加了鹅盲肠有益菌的生长，抑制了有害菌的增殖。总之，这些结果为在匈牙利白鹅日粮中添加 CHAA 和 CHAB 提供了重要的参考。研究结果表明，这种补充物可以显著改善肉质，调节免疫系统，塑造肠道微生物群落组成。
