试验旨在探讨废弃蛹虫草培养基作为蛋鸡生产饲料的可行性.在蛋鸡基础饲粮中分别添加100 g/kg、200 g/kg、300 g/kg的废弃蛹虫草培养基.结果表明,废弃蛹虫草培养基在蛋鸡日粮中的最佳添加量为10％.根据鸡蛋常规指标的测定结果,用废弃的蛹虫草培养基喂养的蛋鸡产蛋重量高于用普通蛋鸡喂养的蛋鸡.试验组白细胞介素-1含量显著高于对照组,白细胞介蛋白-1浓度增加141.5 pg/mL,表明废弃蛹虫草培养基的应用有效提高了蛋鸡的免疫力.对两组蛋鸡肠道内容物的高通量分析表明,实验组肠道微生物种群丰度大于对照组,废弃蛹虫草培养基的应用增加了蛋鸡肠道细菌的多样性.此外,鸡肠道中的一些致病菌对药物的敏感性也有所提高,从而减少了抗生素的使用.蛹虫草废弃培养基的二次利用具有很大的开发利用前景,为蛹虫草废弃培养基在蛋鸡生产中作为饲料的开发提供了科学参考和基本理论依据.
Effect of dietary supplementation with discarded nutrient medium of Cordyceps militaris on laying performance and diversity of intestinal flora in laying hens
The aim of the experiment was to explore the feasibility of discarded nutrient medium of Cordyceps militaris as feed in the production of laying hens.100 g/kg,200 g/kg,300 g/kg of discarded nutrient medium of Cordyceps militaris were added to the basal diet of laying hens.The results showed that the optimal addition of discarded nutrient medium of Cordyceps militaris in the diet of laying hens was 10％.According to the results of measuring the conventional indicators of eggs,the weight of eggs produced by laying hens fed with discarded nutrient medium of Cordyceps militaris was higher than that of laying hens fed with ordinary laying hens.The content of interleukin-1(IL-1)in the experimental group was significantly higher than that in the control group,and the concentration of IL-1 increased by 141.5 pg/mL,which indicated that the application of discarded nutrient medium of Cordyceps militaris effectively improved the immunity of laying hens.The high-throughput analysis of the intestinal contents of the two groups of laying hens showed that the microbial population abundance of the intestinal tract of the experimental group was greater than that of control group,and the application of discarded nutrient medium of Cordyceps militaris increased the diversity of bacteria in the intestinal tract of laying hens.In addition,the sensitivity of some pathogenic bacteria in the intestinal tract of chickens to drugs was also increased,thereby reducing the use of antibiotics.The secondary utilization of discarded nutrient medium of Cordyceps militaris has great development and utilization prospects,which provided a scientific reference and basic theoretical basis for the development of discarded nutrient medium of Cordyceps militaris as feed in the production of laying hens.
