This study investigates the impact of including sorghum in the diet of the common carp () on its growth, blood parameters, meat composition, intestinal microbiota, and oxidative stress. Experimental diets with varying sorghum content (0%-V0 or control, 10%-V1, 20%-V2, and 30%-V3) were administered to carp weighing 43 g initially. Notably, in the 30% variant, sorghum entirely replaced corn and barley in the diet. Chemical analysis of sorghum unveiled a protein content of 14% and a fat content of 3.9%. Sorghum inclusion led to a decline in final body weight and weight gain, particularly notable in the V3 group with 30% sorghum. However, other physiological parameters, such as feed conversion ratio, specific growth rate, and organ indices, remained unaffected. Protein and salt content in carp flesh increased with higher sorghum inclusion levels, while hematological parameters showed minimal variations. Analysis of the intestinal microbiota revealed increases in both aerobic and anaerobic bacterial populations with sorghum inclusion. Furthermore, sorghum concentration inversely correlated with glutathione levels and positively correlated with malondialdehyde content, indicating a disruption of antioxidant defense mechanisms and elevated oxidative stress.
本研究调查了在鲤鱼（）日粮中添加高粱对其生长、血液参数、肉成分、肠道微生物群和氧化应激的影响。将含有不同高粱含量（0%-V0或对照、10%-V1、20%-V2和30%-V3）的实验日粮投喂给初始体重为43克的鲤鱼。值得注意的是，在30%的变体中，高粱完全替代了日粮中的玉米和大麦。高粱的化学分析显示其蛋白质含量为14%，脂肪含量为3.9%。添加高粱导致最终体重和体重增加下降，在高粱含量为30%的V3组中尤为明显。然而，其他生理参数，如饲料转化率、特定生长率和器官指数，未受影响。鲤鱼肉中的蛋白质和盐分含量随着高粱添加水平的提高而增加，而血液学参数变化极小。肠道微生物群分析显示，添加高粱后需氧菌和厌氧菌数量均增加。此外，高粱浓度与谷胱甘肽水平呈负相关，与丙二醛含量呈正相关，表明抗氧化防御机制受到破坏，氧化应激升高。
