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 < 0.05). The percentage of bone ash data indicated that quails fed Ca-P-adequate had higher tibia ash compared...

he present study was designed to investigate the efficacy of overdosing of vitamin D3 supplementation on growth performance, carcass parameters and some blood constituents of Japanese quail in one way analysis of variance experiment lasted in 49 days of age. Two hundred and twenty five of one day old of Japanese quail chicks were used. The chicks were distributed into 5 treatments of 3 replicates of 15 birds each. Five levels of vitamin D3 (0, 1500, 3000, 4500 and 6000 ICU/kg diet) were used. The body weight and feed intake were recorded weekly and consequently, body weight gain and feed conversion ratio were calculated. At the end of the experiment, three birds from each group were slaughtered to evaluate carcass parts. Blood serum samples were obtained from chicks at 49 days of age after centrifuged to measure total protein, cholesterol, glucose, calcium, phosphorus and GPT. At 49 days of age, the results showed that, the Japanese quail fed the highest level of vitamin D3 (6000 ICU/kg diet) achieved significantly (P<0.05) the highest body weight and body weight gain and the best feed conversion ratio. No significant (P>0.05) effects due to vitamin D3 supplementation were noticed in dressed% and some blood serum parameters were measured. It was recommended that under the present experimental conditions, the overdose of vitamin D3 (6000 ICU/kg diet) achieved higher growth performance and some carcass traits of Japanese quail.

A trial was conducted to assess the effects of phytase supplementation and substitute Vitamin D3 resource with Panbonis-a herbal vitamin D3 source-(PAN) on performance, some carcass characteristics, tibia and serum parameters of broiler chickens. For this purpose, 11200 one-day-old, mixed sex (5600 male, 5600 female) Ross-308 chicks were administered 7 different diets based on corn, soybean and wheat throughout the 41-day trial. Dietary treatments; control group as T1 (5000 IU vitamin D3), T2 (T1 + 500 FTU g-1 phytase), T3 (3000 IU vitamin D3 + 500 FTU g-1 phytase + 100 mg kg-1 PAN) and T4 (3000 IU vitamin D3 + 500 FTU g-1 phytase + 200 mg kg-1 PAN) were prepared to contain recommended levels of CaP however T5, T6 and T7 were formulated from T2, T3 and T4, respectively, by reducing 18% of Ca and P concentrations. When overall results considered, there was no significant difference among treatments in terms of final live weight, mortality, weight gain, European Production Efficiency Factor (EPEF) and carcass parameters and mortality (P>0.05). While birds consuming diets containing phytase exhibited better FCR than control group without phytase (P<0.05), no additional improvement was obtained with PAN supplementation compared to other treatments without control group. Additionally partial replacement of PAN for synthetic form had no significant effect on tibia parameters and serum Ca, P levels even though serum Mg (in chicks fed sufficient CaP) and calcitriol were increased. These results indicate that PAN could replace some part of synthetic vitamin D3 without any adverse effect in broiler chickens. However, substitution rate of PAN in Ca and P deficient diets should be carefully studied more due to possible adverse effects on feed intake (12-41d) and weight gain (12-41d) as observed in the present study.

An experiment was conducted to evaluate the effects of phytase (PHY), alone or in combination with citric acid (CA), on growing Japanese quails under moderate and severe phosphorus (P) restriction. For this, 504 one-day-old female quails were distributed in a completely randomised design with seven treatments and six replications. Treatments consisted of the following diets: (a) positive control (PC): formulated according to quails nutritional requirements; (b) negative control 40% (NC 40): PC with 40% less aP; (c) NC 40 +PHY; (d) NC 40 +PHY+CA; (e) negative control 65% (NC 65): PC with 65% less aP; (f) NC 65 +PHY; (g) NC 65 +PHY+CA. Phytase and CA were included at 300 FTU/kg and 40 g/kg, respectively. Performance, bone mineralization and plasma mineral concentration were evaluated at day 35; calcium (Ca) and P metabolism, between days 36 and 39. No significant differences in performance, plasma Ca and P were detected between quails fed PC or NC 40 ; however, NC 40 decreased tibia ash (p < 0.01). Treatment NC 65 impaired daily weight gain (p = 0.01), tibia ash (p < 0.01), and tibia optical densitometry (p = 0.03), as well as modified plasma Ca (p < 0.01) and P (p = 0.03) concentrations when compared to PC. Both NC 40 and NC 65 reduced P excretion (p < 0.01). Phytase alone restored tibia ash of NC 40 quails to regular rates. Nevertheless, only PHY and CA combined returned plasma P, tibia ash, tibia optical densitometry, and daily weight gain of quails fed NC 65 to similar values as those observed in PC. In conclusion, PHY alone suppresses the negative effects of moderate P restriction in growing Japanese quails, but fails in this task under severe P restriction. In such a situation, only the combination of PHY and CA ensures regular rates of growth and bone mineralization. This concept should be better explored by producers in order to take full advantage of the reduction in P excretion achieved by lowering dietary P concentrations.

total number of one hundred eighty unsexed seven-days-old quails were used in present study in a 2 × 3 factorial arrangement (2 levels of vitamin A, 0 and 40,000 IU/kg feed) and three levels of vitamin D3 (0, 1500 and 3000 ICU/kg feed). Chicks were randomly divided into six equal treatments of three replicates of ten quails each. Results showed that vitamin A affects significantly (P<0.05) on body weight (BW) at 28 and 35days of age. The highest level of vitamin A (40,000 IU) achieved an increase in BW. Also, vitamin D affects significantly (P<0.05) BW at 42 days of age. The highest levels of both vitamin A and D3(40,000 IU vitamin A and 3000 ICU vitamin D3) in treatment 6 achieved the heights BW compared to control treatment. Vitamin A affects significantly (P<0.05) body weight gain (BWG) during the period from 7-28 and 7-42days of age. The highest level of vitamin A (40,000 IU) achieved an increase in BWG. However, vitamin D affects significantly (P<0.05) on BWG during the period from 7-42 days of age. Vitamin A affects significantly (P<0.05) on feed consumption during (14-21), (21-28), (28-35), and (35-42) days of age. Vitamin A affect significantly (P<0.05) on feed conversion ratio (FCR) during the period from 7-35 and 7-42 days of age. Vitamin D3 affects significant (P>0.05) on FCR during the period from 7-14, 7-21 ,7-28 ,7-35, and 7-42 days of age. The highest levels of both vitamin A and D3(40,000 IU vitamin A and 3000 ICU of vitamin D3/kg) achieved the best values of both BW and BWG compared to control group. Vitamin A didn't affect significantly on carcass characteristics, but vitamin D3 affects significantly on gizzard weight and the highest levels of vitamin D3 (1500 and 3000 ICU /kg feed) achieved a decrease in gizzard weight. Also, the level of 3000 ICU achieved increase in carcass constituents.It can be concluded that the level of 40000 IU vitamin A/kg achieved the highest values of both body weight and body weight gain. The addition of 3000 ICU of vitamin D3/kg feed improved FCR. Therefore, the results of this study show the improvement of growth performance and carcass traits in Japanese quail, especially at the level of 40000 IU vitamin A/kg or 3000 IU/kg of vitamin D3/kg.

A study was conducted to evaluate four different cholecalciferol levels (NRC; modified), using diets supplemented with 200 (control), 1500, 2500 or 3500 IU/kg of cholecalciferol (VIT-D3). Each treatment was assigned to 3 pens of 17 broiler chicks of a commercial strain grown in an open-sided house with sidewall curtains. At 21and 42 days, BW and feed conversion (FCR) were determined. At 42 days, five birds per pen were slaughtered to evaluate tibia and toe ash of the right leg, and incidence and severity of tibial dyschondroplasia (TD) of the left tibia and also measured dressing percentage and breast meat yield. Serum calcium and phosphorus concentrations were also determined. Haemagglutination inhibition antibody titre against Newcastle disease virus and lymphoid organs weight/body weight ratio were also determined. At both 21 and 42 days, the BW of birds fed 1500 IU/kg to 3500 IU/kg of VIT-D3 was significantly greater than birds fed 200 IU/kg. Similarly, better FCR was observed in birds those fed diets of high level of VIT-D3. No significant difference was observed for mortality at any age. Better dressing percentage and breast meat yield were noted in birds fed diets containing 2500 or 3500 IU/kg VIT-D3. Both tibia and toe ash contents were increased (p < 0.05) progressively with increased concentrations of cholecalciferol in feed. The incidence of TD (percentage of birds having TD scores greater than zero) was significantly (p < 0.05) influenced by level of 3500 IU VIT-D3/kg at 42 days. The severity of TD in birds fed diets containing 200 IU/kg VIT-D3 was apparently higher than birds fed diets with higher levels of VIT-D3. Concentrations of calcium and phosphorus minerals in the serum increased progressively with the high level of VIT-D3 supplementation to birds at both 21 and 42 days of age. Feeding levels of 1500 or 3500 IU of vitamin D3 did positively affect the immune system within the parameters measured. It may be concluded that performance, bone mineralization, blood chemistry and immunity against disease in broilers could be maintained when supplementing high level of VIT-D3 incorporated in broiler diets.

This experiment was conducted to investigate the effect of dietary 1a-hydroxycholecalciferol (1a-OH-D 3) in calcium (Ca)-and phosphorous (P)-deficient diets on growth performance, carcass characteristics, tibia related parameters, and immune responses of broiler chickens. A total of 280 one-day-old broiler chickens (Ross 308) were assigned to 20 floor pens and 4 dietary treatments with 5 replicates. Dietary treatments consisted of starter diets (starter diet of treatment A: 1% Ca, 0.73% total phosphorus [tP]; starter diet of treatment B: 0.85% Ca, 0.64% tP þ 5 mg/kg of 1a-OH-D 3 ; starter diet of treatment C: 0.85% Ca, 0.59% tP þ 5 mg/kg of 1a-OH-D 3 ; starter diet of treatment D: 0.85% Ca, 0.54% tP þ 5 mg/kg of 1a-OH-D 3), grower diets (grower diet of treatment A: 0.86% Ca, 0.68% tP; grower diet of treatment B: 0.73% Ca, 0.59% tP þ 5 mg/kg of 1a-OH-D 3 ; grower diet of treatment C: 0.73% Ca, 0.55% tP þ 5 mg/kg of 1a-OH-D 3 ; grower diet of treatment D: 0.73% Ca, 0.50% tP þ 5 mg/kg of 1a-OH-D 3) and finisher diets (finisher diet of treatment A: 0.81% Ca, 0.64% tP; finisher diet of treatment B: 0.68% Ca, 0.56% tP þ 5 mg/kg of 1a-OH-D 3 ; finisher diet of treatment C: 0.68% Ca, 0.52% tP þ 5 mg/kg of 1a-OH-D 3 ; finisher diet of treatment D: 0.68% Ca, 0.48% tP þ 5 mg/kg of 1a-OH-D 3). Results showed that body weight gain (BWG) and feed intake (FI) of broilers in treatment B were similar to those of broilers in treatment A at the end of the trial (P < 0.05). Broilers in treatments C and D had lower BWG and FI than those in treatment A during the whole trial (P < 0.05). Feed conversion ratio, carcass traits and relative weight of lymphoid organs were not affected by dietary treatments (P > 0.05). Dietary treatments had no significant effect on antibody titers against Newcastle and Influenza disease viruses as well as sheep red blood cells. Dietary treatments had no significant effects on tibia ash and tibial dyschondroplasia score. Broilers fed CaP deficient diets had lower tibia Ca and P than those in treatment A (P < 0.05). In conclusion, results indicated that broilers fed CaP deficient diets supplemented with 5 mg/kg 1a-OH-D 3 failed to achieve the same tibia Ca and P values as broilers fed nonphytate phosphorus adequate diets.

The effect of cholecalciferol (D3) and 25-hydroxycholecalciferol (25-OHD3) as isolated or associated sources of vitamin D (100%-0%, 75%-25%, 50%-50%, 25%-75%, 0%-100%) on the productive performance, egg quality, and bone characteristics was evaluated in white egg-laying hens fed two levels of calcium (Ca) and phosphorus (P) in the basal diet (BD) (BD1 = 0.38% Ca - 0.36% available P and BD2 = 3.2% Ca - 0.30% available P). Nine hundred and sixty Dekalb White hens (24 weeks old) were distributed into 80 cages, under a completely randomized factorial design for 16 weeks. The use of associated sources of vitamin D reduced the feed intake and feed conversion ratio, as well as BD1, which also increased the egg production and egg mass. The association of vitamin D sources with up to 50% 25-OHD3 increased the eggshell percentage. There was interaction (p<0.05) between the sources of vitamin D and the concentrations of Ca and available P, sources with at least 50% 25-OHD3 increased ash per...

This experiment was conducted to examine the effects of 1-α(OH)D3 alone or in combination with different levels of cholecalciferol on performance, and tibia parameters of one-d–old male broilers fed a tibial dyschondroplasia (TD)-inducing diet. A total of three hundred male broilers were randomly allocated to 5 treatment groups with 4 replicates. The dietary treatments consisted of TD inducing diet, TD inducing diet supplemented with 5 μg per kg of 1-α(OH)D3; TD inducing diet supplemented with 5 μg per kg of 1-α(OH)D3 and 1,500; 3,000 or 5,000 IU cholecalciferol kg of diet. At 42 d of age, broiler chickens fed diets containing 1-α(OH)D3 and 1,500 IU cholecalciferol kg of diet had higher body weight (p < 0.05). In the complete experimental period the best FCR and the highest daily weight gain were obtained in broilers supplemented with 1-α(OH)D3 and 1,500 IU cholecalciferol kg of diet. Broilers supplemented with 1-α(OH)D3 and 1,500 IU cholecalciferol kg of diet had significantly l...
