“…Estes resultados não confirmam a hipótese de que aves mantidas sob estresse por calor necessitam de maior aporte de vitaminas e minerais, conforme proposição de Coelho & Mcnaughton (1995). Os resultados de consumo de ração estão de acordo com os encontrados por Vieira Vaz (2006), que também não observou efeito da adição de vitamina C (0 a 400 mg/kg de ração) sobre o consumo de ração por frangos de corte mantidos em ambiente de alta temperatura na fase de 1 a 21 dias de idade.…”

“…Como as modificações nas instalações para criação de frangos são normalmente alternativas caras, a manipulação nutricional de rações visando atenuar os efeitos negativos das altas temperaturas vem ganhando importância. Pesquisas têm comprovado que aves mantidas sob estresse térmico necessitam de maior aporte de vitaminas e minerais (El-Boushy, 1988;Coelho & McNaughton, 1995;Miltenburg,1999), visto que altas temperaturas, além de reduzir a síntese de vitamina C, também prejudicam a absorção das vitaminas C e E, alterando suas exigências.…”

RESUMO -O experimento foi realizado para avaliar os efeitos da suplementação das vitaminas C ou E na ração sobre o desempenho, as características de carcaça e os parâmetros hematológicos de frangos de corte mantidos em ambiente de alta temperatura. Foram utilizados 450 frangos de corte distribuídos em delineamento inteiramente ao acaso, com cinco tratamentos, cada um com nove repetições de 10 aves (período 1 a 21 dias) ou de 7 aves (período de 22 a 42 dias) por unidade experimental. Os tratamentos foram: ração basal (RB) sem suplementação de vitaminas C e E; RB + 300 ppm de vitamina E; RB + 230 ppm de vitamina C; RB + 300 ppm de vitamina E + 230 ppm de vitamina C; e RB + 150 ppm de vitamina E + 115 ppm de vitamina C. Não houve efeito da suplementação das vitaminas C e E no desempenho zootécnico das aves na fase de 1 a 21 dias de idade. Na fase de 1 a 42 dias, a suplementação das vitaminas C e E influenciou somente a conversão alimentar. Os melhores resultados para os pesos absoluto e relativo de peito foram observados nas aves que receberam a ração basal suplementada com as combinações das vitaminas C e E. A concentração plasmática de triiodotironina, a porcentagem de células sanguíneas, a relação heterófilo/linfócito e os pesos absoluto e relativo do baço aos 21 e 42 dias de idade não foram influenciados pela suplementação vitamínica. A suplementação das vitaminas C e ou E não influi no desempenho zootécnico, no peso do baço e nos parâmetros sanguíneos de frangos de corte mantidos até 42 dias de idade em ambiente de alta temperatura. As combinações das vitaminas C e E promovem melhora nos pesos absoluto e relativo de peito de frangos de corte sob alta temperatura.

“…The supplement industry works with a safety margin of two to ten times greater than the actual need of the birds, to guarantee the minimum supplementation of the nutrients after the manufacturing physical processes, transportation and diets storage (COELHO et al, 1995;FÉLIX et al 2009). However, BRITO et al (2010) did not recognize the advantage of using high levels of vitamin D 3 on performance of broilers, as well as ALAHYARI-SHAHRASB et al (2012) suggested that it has been possible to reduce the amount of some vitamins in the premix for finisher's diets by 33% without affecting the performance and metabolic characteristics.…”

Decreased levels of vitamin D3 and supplementation with 1,25-dihydroxyvitamin D3-glycoside on performance, carcass yield and bone quality in broilers

et al. 2018

An experiment was performed to evaluate the effect of decreased levels of vitamin D3 in the premix and 1,25-dyhydroxyvitamin D3-glycoside (1,25(OH)2D3-glycoside) supplementation on performance, carcass yield and bone quality in 42d old broilers. Seven-d-old male chickens Cobb500® were distributed in a randomized design with six treatments: a control diet with inclusion of vitamin D3 in the premix, without supplementation of 1,25(OH)2D3-glycoside, and five diets with decreased levels of vitamin D3 (100%, 75%, 50%, 25% and 0% about the control) plus the addition of 1,25(OH)2D3-glycoside, 50g ton-1 of diet. The main results were to reduce the tenor of Vitamin D3 in the premix when the addition of 1,25(OH)2D3-glycoside did not affect (P>0.05) the performance, carcass yield and bone quality variables. However, performance (feed intake, gain weight, feed conversion), yield (warm carcass weight) and bone quality (dry weight, length, mineral matter and breaking strength) of broilers fed with diets without vitamin D3 in the premix and with addition of 1,25(OH)2D3-glycoside, which was the single source of vitamin D, had as a result very low (P<0.05) values comparing to the control. For the purposes of the present research, it was concluded that is possible the reduction of vitamin D3 tenor in the premix up to 75% when the diet of male broilers is supplemented with 1,25(OH)2D3-glycoside. However, the use of 1,25(OH)2D3-glycoside as a single source of vitamin D, as tested here, is not recommended for broilers diets.

“…However, vitamins are essential for a normal metabolism. They also cause a specific deficiency disease if absent from the diet and cannot be synthesized by the host animal to meet vitamin requirements (Coelho and McNaughton, 1995). Skinner et al (1992) reported that removing vitamin (V) and trace mineral (TM) premixes from broiler diets from 28 to 49 days of age had little impact on growth performance.…”

Two experiments were conducted the to compare the effect of a decreasing amount of vitamin premix in diets inbroilers from 29 to 42 days of age on carcass composition and blood chemistry in floor (Experiment 1) and battery cage (Experiment 2) systems. At 35 and 42 days of ages, one bird of each replicate was slaughtered and carcass composition was measured. Blood concentrations of alkaline phosphatase (ALP) and calcium (Ca) were used to diagnose vitamin D3 deficiency and enzymes aspartate amino transferase (AST) to identify vitamin E deficiency. Floor raised birds showed that vitamin premix reduction/withdrawal at 29 days of age did not impair body weight (BW), carcass composition, ALP and Ca during the final rearing period. However, diet without vitamin premix (T1) had a higher AST at 42 days of age than the other diets. Birds reared in cages were slightly more sensitive to vitamin premix reduction/withdrawal, probably due to the impracticality of performing coprophagy. Diet without vitamin premix (T1) had a lower BW, carcass breast and thigh yield at 42 days of age; also serum ALP, AST and Ca were impaired. In conclusion, the withdrawal of vitamins is not a reasonable option but it is possible to reduce vitamin premix in finisher broilers' diets without negative effects on performance and on some metabolic traits during the finisher period with both methods of rearing.
