Influence of dietary 1αlpha-hydroxycholecalciferol, individually or in combination with microbial phytase in calcium and phosphorus deficient diets on growth performance and tibia parameter of Japanese quails (<i>Coturnix japonica</i>)

Abstract

The effect of 1α-OH-D3 in calcium-phosphorus (Ca-P) deficient diets on Japanese quail growth performance and tibia parameters was investigated. Eight-day-old (n = 160) newly hatched quails were weighed and randomly allocated to 20 groups, each with 4 replicate pens of 8 birds. Treatments were as follows: T1, Ca-P-adequate; T2,Ca-P-deficient; T3, Ca-P-deficient + 500 FTU kg-1 of phytase (Ph); T4, Ca-P-deficient diet + 5 µg kg-1 of 1α-OH-D3; T5,Ca-P-deficient + Ph + 5 µg kg-1 of 1α-OH-D3. Results showed that quails fed Ca-P-adequate had significantly higher body weight compared with quails fed Ca-P-deficient, Ca-P deficient supplemented with 1α-OH-D3 and Ca-P-deficient supplemented with 1α-OH-D3 and phytase, but did not differ from Ca-P-deficient diet supplemented with phytase. Quails fed Ca-P deficient were unable to achieve FCR comparable to quails fed Ca-P-adequate (p &lt; 0.05). The percentage of bone ash data indicated that quails fed Ca-P-adequate had higher tibia ash compared with other groups except for quails fed Ca-P deficient diet supplemented with combination of 1α-OH-D3 and phytase. Quails fed Ca-P-adequate had higher tibia P compared with quails fed Ca-P-deficient. In conclusion, these results indicated that quails fed Ca-P-deficient supplemented with 5 µg kg-1 of 1α-OH-D3 in combination of 500 FTU kg-1 of phytase were able to achieve the same tibia ash and Ca compared with quails fed Ca-P-adequate.

The effects of 1a(OH)D3 individually or in combination with phytase, and different levels of cholecalciferol on performance, tibia criteria, and plasma minerals of Japanese quails

“…Snow, Baker, and Parsons, (2004) investigated efficacy of 1-α(OH)D3 alone or in combination with phytase on phytate phosphorus utilization in broiler chicks fed a corn-soybean meal diet; the results indicated that a positive interaction exist between 1 -α(OH)D3 and phytase. Kheiri, Poshtvar, Jalali Haji Abadi, and Landy, (2019) compared efficacy of 1 -α(OH)D3 alone or in combination of microbial phytase on broiler quails performance and quality of tibia; the result indicated positive interaction between 1-α(OH)D3 and phytase on bone mineralization. Edwards Junior et al (2002) reported that supplementation of 1-α(OH)D3 to broiler chicken's diet which didn't contain cholecalciferol resulted in better performance.…”

Investigation of different levels of cholecalciferol and its metabolite in calcium and phosphorus deficient diets on growth performance, tibia bone ash and development of tibial dyschondroplasia in broilers

“…The results showed that 1-α(OH)D 3 can be used as a substitute for cholecalciferol. Several studies investigated the efficacy of 1-α(OH)D 3 alone or in combination of phytase where the results showed a positive interaction between 1-α(OH)D 3 and phytase (Snow, Baker, & Parsons, 2004;Driver, Pesti, Bakalli, & Edwards, 2005;Kheiri, Poshtvar, Jalali Haji Abadi, & Landy, 2019). Ghasemi, Toghyani, & Landy (2018) investigated the efficacy of 1-α(OH)D 3 alone in Ca-P deficient diets, and the results indicated that 1-α(OH)D 3 couldn't improve tibia parameters of broilers.…”
