“…1α-hydroxycholecalciferol (1α-OH-D 3 ) and ) are derivatives of vitamin D. Their bioavailability is higher than that of vitamin D 3 . 25-OH-D 3 is nearly twice as active as vitamin D 3 (Soares et al, 1995) and 1α-OH-D 3 is 5 to 8 times as effective as vitamin D 3 in broilers (Edwards et al, 2002;Han et al, 2013). 25-OH-D 3 has been approved for use in feed for broiler chickens, laying hens, and turkeys in Europe, USA, and China.…”

-A 7 × 2 factorial experiment was designed to test the effects of calcium (Ca) to non-phytate phosphorus (NPP) ratio (1.14, 1.43, 1.71, 2.00, 2.29, 2.57, and 2.86) and different sources of vitamin D (1α-hydroxycholecalciferol (1α-OH-D 3 ) and 25-hydroxycholecalciferol (25-OH-D 3 )) on growth performance and bone mineralization in 1-to 42-d-old broiler chickens. On the day of hatch, 700 female Ross 308 broilers were weighed and randomly assigned to 14 treatments with five stainless steel cages of 10 birds each. Dietary Ca levels were 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, and 10.0 g kg −1 and the NPP content was 3.5 g kg −1 . The dose of 1α-OH-D 3 or 25-OH-D 3 was 5 µg kg −1 . Diets were not supplemented with cholecalciferol (vitamin D 3 ). Results showed that the Ca to NPP ratio, vitamin D source, and their interaction affected body weight gain (BWG), feed intake (FI), feed efficiency (FE), and carcass and breast yields, as well as tibia weight and length and ash weight in broiler chickens from 1 to 42 d of age. Broilers fed 1α-OH-D 3 had higher BWG and FI as well as tibia breaking strength, weight, length, diameter, and ash weight than birds fed 25-OH-D 3 at 42 d of age. The Ca to NPP ratio had a quadratic effect on BWG, FI, mortality, as well as tibia breaking strength, weight, length, ash weight, and ash and P contents in 42-d-old broilers. Broiler chickens at 42 d of age obtain optimal growth performance and bone mineralization at the Ca to NPP ratio of 2.32 when 1α-OH-D 3 or 25-OH-D 3 are used as the vitamin D source.

“…Chickens obtained the highest growth rate, bone ash, and Ca and P retention when they were fed with diets of Ca to total phosphorus (tP) ratios ranging from 1.1 to 1.4:1 (Qian et al, 1997). The metabolite of vitamin D, 1α-hydroxycholecalciferol (1α-OH-D 3 ), is 5 to 8 times as active as vitamin D 3 in promoting growth and tibia ash content Han et al, 2013). The compound 1α-OH-D 3 had positive effects on growth and bone mineralization in broiler chickens (Biehl and Baker, 1997).…”

This study evaluated the effects of dietary non-phytate phosphorus (NPP) and 1α-hydroxycholecalciferol (1α-OH-D 3 ) on the growth performance, bone mineralization, and carcass traits of 1-to 21-day-old broiler chickens. On the day of hatch, 600 male Ross 308 chicks were weighed and randomly assigned to 12 treatments, with five cages of 10 birds each. A 6 × 2 factorial arrangement was applied, consisting of 0.20%, 0.25%, 0.30%, 0.35%, 0.40%, or 0.45% NPP and 0 or 5 μg/kg of 1α-OH-D 3 . The basal diet contained 0.52% calcium (Ca) and was not supplemented with vitamin D 3 . Dietary NPP levels significantly affected growth performance and tibia mineralization (except width) of broilers; by contrast, meat yield and organ relative weight were not influenced by NPP. The inclusion of 1α-OH-D 3 improved growth performance, tibia mineralization, and carcass and breast yield, whereas it decreased the relative weights of the liver, heart, and kidney. A significant interaction between NPP and 1α-OH-D 3 was observed for body weight gain (BWG), feed efficiency (FE), mortality, serum Ca and P levels, tibia breakingstrength, ash weight, and Ca content, as well as breast yield and heart relative weight. These results suggest that broilers fed with 5 μg of 1α-OH-D 3 per kg of diet obtain optimal growth performance and tibia mineralization when dietary NPP level was 0.30% and the analyzed Ca to NPP ratio was 1.97.
