Objective: To assess the toxic potential of Dissotis rotundifolia(***) whole plant extract in Spraque–Dawley rats within a 2-week period of ***: Methanolic extract of D. rotundifolia was administered orally once daily at dose levels of 0,100, 300 and 1 000 mg/kg body weight for 14 days. Toxicity was assessed using mortality, clinical signs, body and organ weights, hematological indices,serum chemistry parameters and histopathological ***: There were no treatment-related mortalities or differences in clinical signs,hematology and serum biochemistry. This was confirmed by micrographs obtained from histopathological ***: The results obtained from the sub-acute toxicological assessment of D. rotundifolia extract suggest that the extract is non-toxic at doses up to 1 000 mg/kg/day administered for a period of 14 days.

随着动物营养研究的深入,核苷酸在饲料中的功能和作用机理也逐步被人们重新认识。核苷酸作为细胞合成的必需物质,具有保护肠道黏膜、增强机体免疫力等生理功能。在正常情况下,成年动物可以通过内源性核苷酸来满足自身的需要,不需特意的补充。但近年来的一些研究表明,当机体迅速生长或受到免疫挑战时,内源性核苷酸就不能满足动物组织和细胞代谢的需要,此时必须补充外源性核苷酸,以保证组织的生长和正常生理功能。本文综述了在动物应激、快速生长和预防疾病等情况下,动物体内核苷酸的需求情况及其重要的生理功能,由此阐述了核苷酸作为新型饲料添加剂在生产中的作用。
