This study was conducted to evaluate the relative bioavailability (RBV) of 25-hydroxycholecalciferol (25-OH-D3) to cholecalciferol (vitamin D3) in 1- to 21-d-old broiler chickens fed with calcium (Ca)- and phosphorus (P)-deficient diets. On the day of hatch, 450 female Ross 308 broiler chickens were assigned to nine treatments, with five replicates of ten birds each. The basal diet contained 0.50% Ca and 0.25% non-phytate phosphorus (NPP) and was not supplemented with vitamin D. Vitamin D3 was… 
Partial Replacement of Dietary Cholecalciferol with 25-Hydroxycholecalciferol on Broiler Chickens Subjected to a Coccidiosis Vaccine Challenge
TLDR
The results of the present study suggested that dietary D3 and 25-OH-D3 at concentrations above the control group (50–200 μg/kg of feed) were effective.
Relative bioavailability determination of highly concentrated cholecalciferol (vitamin D3) sources employing a broiler chick bioassay
TLDR
This protocol was able to detect differences between highly concentrated D3 sources and may be employed to evaluate D3 biological activity.
Relative biological value of 1&agr;‐hydroxycholecalciferol to 25‐hydroxycholecalciferol in broiler chicken diets
TLDR
Data indicate that when directly feeding a hormonally active form of vitamin D as 1&agr;‐OH‐D3 proportionally less is needed than when using the precursor (25‐OH-D3) in diets deficient in Ca and P.
Effects of dietary 25-hydroxyvitamin D3 supplementation on growth performance, immune function and antioxidative capacity in weaned piglets
TLDR
Overall, feeding high-dose 25(OH)D3 to weaned pigs partly improved immune functions and the antioxidative capacity.
Classic and Non-Classic Effects of the Duration of Supplementation of 25-Hydroxicholecalciferol in Broiler Chicken Diets
TLDR
The supplementation of 25(OH)D3 increased breast yield and protein deposition in the breast muscle which may have been a result of the epigenetic changes caused by this vitamin D (Vit D) metabolite.
Effect of dietary 25-hydroxycholecalciferol on the sternal mass of meat ducks under different vitamin regimens
TLDR
It is indicated that the dietary administration of 25-OH-D3 increased sternal mass in NRC vitamin diet by suppressing bone resorption in 49-day-old meat duck.
Effects of dietary calcium and phosphorus levels and supplementation of 25-hydroxycholecalciferol on performance and bone properties of broiler starters
TLDR
Overall, feeding 25OHD3 at 69 μg/kg feed to broilers had no effect on growth performance but partly improved bone biochemical and biomechanical properties of broiler starters.
LATE STAGE RESPONSES OF LAYING CHICKENS FED DIETS SUPPLEMENTED WITH DIFFERENT SOURCES AND LEVELS OF VITAMIN D: 1- PRODUCTIVE AND REPRODUCTIVE PERFORMANCE.

TLDR
It is recommended that 25-OHD3 should combine with VD3 in layer diets at late stage but not more than 0.17375 mg/kg, asHen's persistence showed clear improvement and feed intake of entire experimental period was increased significantly by increasing VD than NRC 1994.
Efficacy of dietary vitamin D and its metabolites in poultry - review and implications of the recent studies
TLDR
The results of several recent poultry studies have shown that 25-hydroxycholecalciferol (25-OH-D3) is more efficient in commercial poultry nutrition than the basic form of vitamin D3 (chole CALCiferol).

Twenty-five hydroxycholecalciferol as a cholecalciferol substitute in broiler breeder hen diets and its effect on the performance and general health of the progeny.
TLDR
When comparing vitamin D sources, 25-OHD3 had greater potency than D3 only at very low levels of supplementation, and in relation to vitamin D3 depended on the level tested.
Comparison of dietary 25-hydroxycholecalciferol and cholecalciferol in broiler chickens.
TLDR
Evaluation of different dietary levels of 25-OH-D3 revealed a significant dose-response relationship, with maximal effects on weight gain, feed efficiency, and breast meat yield being observed in the range of 50 to 70 micrograms/kg feed.
Dietary Calcium Levels Reduce the Efficacy of One Alpha-Hydroxycholecalciferol in Phosphorus-Deficient Diets of Broilers
One alpha-hydroxycholecalciferol (1α-OH D3), an analog of cholecalciferol (vitamin D3), improves growth performance and phosphorus retention in broilers. In the present study, we investigate the
The influence of vitamin A on the utilization and amelioration of toxicity of cholecalciferol, 25-hydroxycholecalciferol, and 1,25 dihydroxycholecalciferol in young broiler chickens.
TLDR
It is indicated that high dietary vitamin A interferes with the utilization of vitamin D3, 25-(OH)D3 and 1,25-dihydroxycholecalciferol [1,25-( OH)2D3] in young broiler chicks, increasing the requirement for each of them.
Effectiveness of twenty-five-hydroxycholecalciferol in the prevention of tibial dyschondroplasia in Ross cockerels depends on dietary calcium level.
TLDR
The effectiveness of 25-hydroxycholecalciferol to reduce the incidence of TD in young broilers was higher when the dietary calcium level was below 0.85%.
Evaluation of a Fermentation Source of 25-hydroxycholecalciferol in Broiler Diets1
TLDR
Analysis of the data indicated no significant differences in performance between chicks fed the two sources of 25-OH-D3 although numerical differences in weight gain and feed conversion were observed that neared statistical significance.
Effect of Source and Level of Vitamin D on Live Performance and Bone Development in Growing Broilers
TLDR
Results of the study show that 25-OH-D3 is more metabolically potent on a per unit basis than VIT-D 3 for support of BW, tibia ash, and reduction in incidence and severity of TD.
Efficacy of different limestone particle size and 25-hydroxycholecalciferol in broiler diets
TLDR
Replacement of cholecalciferol by 25-OH-D3 at a level of 50 and 60% had a beneficial effect on body weight gain and feed conversion, 100% substitution, on the Ca content of the tibia, whereas 50, 60, 80 and 100% replacement, on Ca and P balance.
25-hydroxycholecalciferol in poultry nutrition.
TLDR
It seems that 25-(OH)D3 is the most active metabolite of vitamin D3, ultimately capable of supporting both cellular functions and embryonic development in chickens and turkeys when fed as the sole source of vitaminD3.
