Rhizoma Drynariae



  • Bone_strength
Gu-Sui-Bu (Rhizoma Drynariae) is one of the most frequently used traditional Chinese medicines for its antiosteoporosis activities related to improving bone strength and promoting bone fracture healing. These properties made it attractive to the poultry industry for improving bone strength of hens on low-calcium diets and broilers suffering from tibial dyschondroplasia.

Hens500-2000 mg/kgantiosteoporosis Protected the bone tissue and prevented bone density from decreasing in the legs of hens on low-calcium diets. J Huang et al., 2019
Hens2.0 g/kgantiosteoporosis Enhanced the activities of serum total antioxidant capacity and glutathione peroxidase. Increased femur and tibia bone mineral density. reduced the activities of serum alkaline phosphatase, tartrate resistant acid phosphatase, and the contents of osteocalcin. Improved microstructure of bone tissue. Significantly increased egg weight.J Huang et al., 2020
Broilers20 mg/kgtibial dyschondroplasiaimproved the growth performance of the tibial dyschondroplasia in chickens and allowed them to recover to normal activity. W Yao et al., 2018
Broilers125 mg/kgadditivethe addition altered the levels of marker differential metabolites in broiler breast muscle through amino acid metabolic pathways, lipid metabolic pathways, and energy metabolic pathways, thereby protecting breast muscle from AFB1-induced meat loss, oxidative stress, and inflammatory response. The present study enables to understand how AFB1 affects broiler breast muscle quality and contributes to the use of TFRD (main ingredient rutin) as a potentially safe and harmless herbal extract in poultry production.K Yue et al., 2023
