“…These results are contrary to the ones found by Souza et al (2013). The authors evaluated the performance of broilers supplemented with 1,25(OH) 2 D 3 levels ranging from 0 to 5 µg/kg, reducing in 20% the levels of available calcium and phosphorus.…”

This study was conducted to evaluate the effect of two levels of vitamin D 3 with or without 1,25dihydroxycholecalciferol (1,25(OH) 2 D 3) on live performance and bone quality of broiler chickens. For that, we used a completely randomized design in a 2 × 2 factorial arrangement, with eight replicates of 30 Cobb ® 500 male broiler chicks each (n = 960). The two levels of vitamin D 3 and the addition or not of 0.5 µg 1,25(OH) 2 D 3 /kg were considered as main factors. The vitamin D 3 levels were: 2500/2000 IU/kg and 1250/1000 IU/kg for the starter (1 to 21 days) and grower (22 to 40 days) phases, respectively, with the first representing the levels used in industry (100%) and the second, a reduction in 50% of those levels. The 1,25(OH) 2 D 3 source was Solanum glaucophyllum. On days 21 and 40, one broiler per replicate was killed and long bones were removed for analyses of mineral percentage, bone mineral density, biomechanical properties, and morphology. No significant differences were found related to vitamin D 3 levels and the addition or not of 1,25(OH) 2 D 3 for live performance, mineral percentage, strength, stiffness, and morphology. Toughness was lower when 1,25(OH) 2 D 3 was used at 21 days, but this effect was not observed at 40 days of age. Bone mineral density was greater when 100% of vitamin D 3 was used at 40 days of age. The reduction of up to 50% of vitamin D 3 levels is sufficient to ensure performance and bone development of broilers at 21 and 40 days of age. The inclusion of 0.5 µg 1,25(OH) 2 D 3 /kg in addition to diets with sufficient levels of vitamin D 3 shows no effect on the improvement of those parameters at the same ages.

“…Os resultados observados assemelharam-se aos descritos por Roberson and Edward (1996), que ao adicionar 3,0; 6,0 e 9,0 µg de 1,25(OH) 2 D 3 nas rações para frangos de corte, não encontraram diferenças significativas para o CR e GP. Souza et al (2013) apontaram a viabilidade do uso suplementar de vitamina D 3 ativa nas rações para frangos de corte. Segundo os autores, haveria uma sensível melhora na absorção e utilização de Ca e P pelas aves, especialmente em condições de restrição de Ca e P disp .…”

“…As estratégias nutricionais, tais como a suplementação de vitaminas e a redução de minerais, principalmente cálcio e fósforo, nos planos alimentares estão direcionadas para a otimização do desenvolvimento corporal e do tecido ósseo das aves. Souza et al (2013) verificaram que rações suplementadas com níveis de 1,0 ou 2,0 μg de 1,25(OH) 2 D 3 /kg ração de origem herbal (Solanum glaucophyllum) interferiram positivamente no ganho de peso e na conversão alimentar de frangos de corte restritos em cálcio e fósforo.…”

1,25-dihydroxycholecalciferol from plant source (Solanum glaucophyllum) maintains the performance and bone quality of female broilers during restriction of calcium and phosphorus sUMMarY The supplementation with 1,25-dihydroxycholecalciferol (1,25(OH) 2 D 3 ) has been evaluated as an alternative to reduce dietary concentrations of calcium (Ca) and phosphorus (P). Thus, the objective of this study was to determine the best level of dietary supplementation of 1,25(OH) 2 D 3 from plant source (Solanum glaucophyllum) to female broiler chickens restricted in Ca and available P (aP). A total of 684 day-old chicks were weighted and equally distributed in a completely randomized design with six treatments and six replications of 19 birds. Treatments consisted of a positive control (PC): corn-and soybean-meal diet formulated to reach animals' nutritional requirements; a negative control (NC): PC diet with 15% reduction in dietary Ca and aP concentrations; and four NC diets supplemented with 0.5, 1.0, 1.5 or 2.0 µg/kg of 1,25(OH) 2 D 3 . Growth performance was evaluated at 42 days; bone mineralization characteristics, at 21 and 33 days. Broilers fed NC decreased feed intake (P<0.05), but not weight gain and feed conversion ratio. At day 21, the supplementation of NC with 1,25(OH 2 )D 3 did not return tibiotarsus ash to the same level as that observed in broilers fed PC, but it kept other bone characteristics at simmilar values. At day 33, broilers fed NC supplemented with 1,25(OH 2 )D 3 showed higher bone weight. Overall, broilers fed 2.0 µg/kg of 1,25(OH) 2 D 3 had higher ash content than those fed PC. additional keYwordsActive D3 vitamin. Ash. Bone strength.

“…The use of 1,25(OH) 2 D 3 has been studied in poultry production with the aim of improving the relationship between growth and bone tissue strength, thus reducing locomotor problems (SOUZA et al, 2013;VIEITES et al, 2014). The hydroxylated metabolites of vitamin D 3 and 7-dehydrocholesterol have been identified in several plants, in particular in those belonging to the Solanaceae family (JÄPELT;JAKOBSEN, 2013).…”

<p>O objetivo do trabalho foi avaliar as características dos tibiotarsos de frangos de corte machos aos 21 e 35 dias de idade. Foram determinados os percentuais ósseos de proteínas colagenosas (PC), proteínas não colagenosas (PNC), cinzas e minerais (cálcio, fósforo, potássio e sódio), além dos pesos dos tibiotarsos <em>in natura, </em>secos e desengordurados. Foram utilizados 648 frangos de corte machos da marca comercial Cobb® em um delineamento em blocos ao acaso com seis tratamentos e seis repetições com 18 aves por unidade experimental. Os tratamentos consistiram na suplementação de 0,0; 0,5; 1,0; 1,5; 2,0 e 2,5 ?g de vitamina D3 ativa/kg de ração. Aos 21 e 35 dias de idade as aves foram pesadas e um frango/repetição com o peso médio do lote foi retirado e abatido para se obter os tibiotarsos. A composição orgânica e mineral dos ossos foi afetada pelo fornecimento suplementar de vitamina D3 ativa nas rações. Recomenda-se até 1,50 ?g de 1,25(OH)2D3/kg de ração para frangos de corte machos de 8 a 35 dias de idade.</p>
