HaoD - 25 هيدروكسي فيتامين D3

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
