25-Hydroxyvitamin D3

1. Effects on Broilers

Improves calcium and phosphorus absorption efficiency, promotes bone development, 

and reduces the incidence of rickets and leg weakness; improves muscle growth rate and 

quality, and increases feed conversion ratio; enhances immune function, reduces the risk 

of disease infection during the breeding process, and improves uniformity at slaughter.

2. Effects on Laying Hens

Optimizes calcium deposition and utilization, significantly improves eggshell thickness,

 strength, and gloss, and reduces egg breakage rate; prolongs the peak laying period and 

stabilizes egg production performance; promotes bone health and reduces the probability 

of osteoporosis and cage fatigue in laying hens.

3. Effects on Cattle and Lambs

1）Calves and Lambs: Promotes calcium and phosphorus absorption, aids in bone and 

teeth development, and reduces the incidence of rickets and osteomalacia in young animals; 

enhances immunity, alleviates the impact of weaning stress on growth, and improves survival 

rate.

2） Fattening cattle and sheep: Improves mineral metabolism, promotes muscle growth and 

fat deposition, and enhances carcass quality; increases feed conversion rate, accelerates fattening,

 and reduces feed conversion ratio.

3） Lactating cattle and sheep: Ensures adequate calcium and phosphorus supply to the mother, 

reducing the risk of postpartum paralysis; increases calcium content in milk, supporting the growth 

and development of calves and lambs; improves reproductive performance and shortens the estrus 

interval after calving.

4. Effects on fish

Promotes calcium and phosphorus absorption and bone calcification in fish, reducing the incidence

of deformities; enhances fish's stress resistance, alleviating stress damage caused by sudden changes 

in water quality and high-density aquaculture; improves growth performance, increases feed utilization, 

and promotes rapid fry rearing.
