25-hydroxyvitamin D3 (25-OH-D3 ) , namely 25-hydroxycholecalciferol , an important nutrient for healthy bones , is the metabolic product of the liver hydroxylation of vitamin D3 . It is the main active form of vitamin D in human and animal blood circulation , and is an indicator of the nutritional status of vitamin D3 in the body.
Molecular Structure
Cyclopentane polyhydrophenanthrene structure;
25-OH-7-DHC , special light rearrangement equipment , open loop to get 25-OH-D3 ; 1 .25% of 25-OH-D3 was obtained by microencapsulation .
Features
The biological potency is 3 ~ 5 times of vitamin D3 , which can be transformed into the final active metabolite more effectively;
No liver conversion is required , which shortens the metabolic process of vitamin D3 and makes it absorbed more quickly;
Not impacted by intestinal malabsorption , liver damage or liver dysfunction;
The absorption mode is different from that of fat-soluble vitamins (A , D3 , E , K3 ) and does not depend on bile secretion and the formation of fat-absorbing micro- aggregates .
Dosage
Function
SWINE
Sows
Improve skeletal development , reduce foot and limb disease , improve gilt selection rates ,extend the service life;
Improve the pregnancy rate , improve the reproductive performance of sows ( live litter size , newborn and weaning weight , survival rate of piglets , survival rate and healthy rate of piglets , increase litter weight) and milk composition;
Improve the retained placenta , to solve the problem of postpartum paralysis .
Piglets
Impromote calcium and phosphorus absorption and utilization , improve skeleton development , reduce the incidence of rickets and osteoarthro – pathy, improve growth performance , enhance antibody level , enhance disease resistance .
Boars
Increase sperm motility, semen volume and sperm count; increase fertilization rate .
Fattening pig
Before slaughter to improve meat color, improve muscle water retention .
POULTRY
Layer
Prevention of paralytic chicken , reduce the death of chicken; The growth period: promote the skeleton development;
High-yield period: reduce osteoporosis and cage layer fatigue , to extend the laying cycle;
In the later period of laying eggs: the quality of eggshell is improved , the strength of eggshell is increased , the deformed egg , the thin eggshell and the broken eggshell are reduced , and the body weight of chicken is eliminated.
Broilers
Improve growth performance, enhance bone development, promote intestinal development and improve immunity;
Increase the rate of brisket, reduce the rate of bone damage in the process.
Breeding birds
Reduce the number of dead embryos , increase the hatchability, increase the qualified rate of breeding eggs , reduce the number of broken eggs , white shell and thin shell eggs;
Raise the egg production rate , maintain the egg production peak;
To obtain the maximum bone volume before sexual maturity and reduce the early
