Advantages

Lower dose, better effect

Compared to conventional VD₃ at 3,750 IU/kg, nano-VD₃ at 2,500 IU/kg led to significantly higher average daily gain and greater bone indices.

Improves gut health

Increases relative abundance of beneficial bacteria (e.g., Ligilactobacillus, Muribaculaceae) and reduces harmful taxa (e.g., Desulfovibrio).

Stronger bones

Significantly increased yield strength, elastic modulus, and calcium and ash content in femur and tibia.

Applications

• Broiler feed formulation：Replace conventional VD₃ at 2,500 IU/kg to improve weight gain and bone quality.
• Livestock bone health：Enhance femur and tibia mechanical properties to reduce skeletal maldevelopment.
• Feed additives：Low-dose nano-VD₃ as an efficient feed additive that modulates gut microbiota.
