Abstract：This experiment was aimed to investigate the effects of liquid cultured sessile Ganoderma lucidum solution and mycelium on growth performance and nutrient deposition in SD rats, and evaluate its application value in diets. The Ganoderma genus was identified by analysis of the ITS sequence of Ganoderma lucidum DNA. Thirty-six healthy 3-week-old male SD rats were randomly divided into three groups:feeding potato glucose water group (control group), feeding sessile Ganoderma lucidum solution group (solution group) and feeding sessile Ganoderma lucidum mycelium group (mycelium group), with 4 replicates per group and 3 rats per replicate, and fed 4 weeks at a dose of 10 mL/(kg BW·d). The results showed as follows:compared with the control group, the average daily weight gain in solution group increased significantly (P<0.10), the average daily feed intake in mycelium group significantly decreased (P<0.10), while there was no significant effect on the feed conversion rate in solution group and mycelium group (P>0.10); the organ indexes and inosine acid content of Longissimus dorsi in solution group and mycelium group had no significant difference (P>0.05), but the contents of total protein and aspartic acid, serine, glutamate, glycine, alanine, valine, methionine, isoleucine, tyrosine, phenylalanine, histidine and arginine of Longissimus dorsi in solution group significantly increased (P<0.05). In conclusion, feeding sessile Ganoderma lucidum solution and mycelium have no significant effect on the growth of SD rats, but Ganoderma lucidum solution can promote the deposition of total protein and flavor amino acids in muscle.
