蝉花菌质在饲料中应用安全性初探
wf（2023）
Abstract
本研究通过开展蝉花菌质小鼠经口急性毒性试验、 雌性小鼠和雄性小鼠的小鼠骨髓细胞微核试验和小鼠的精子畸形试验评价其安全性,为蝉花菌质作为饲料原料在畜牧行业的应用提供理论依据.研究结果表明,受试的所有ICR小鼠在试验观察期内均未见中毒症状和死亡情况,在试验结束后大体剖检小鼠的肾脏、肺脏、脾脏、肝脏、胃肠道、心脏等组织器官均未发现异常变化,根据本试验判定蝉花菌质对ICR小鼠经口急性毒性试验的半数致死量大于5000 mg·kg-1体重;蝉花菌质在1250～5000 mg·kg-1体重剂量范围内经口染毒后,各小鼠骨髓细胞中含微核嗜多染红细胞率和小鼠精子畸形率与阴性对照组比较均无显著性差异(P>0.05),说明小鼠骨髓细胞微核试验结果和小鼠精畸形试验结果均为阴性.以上试验表明,蝉花菌质具有很好的安全性,可作为饲料添加剂或饲料原料进一步研究开发.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
