Resumo
The objective of this study was to determine the energy values and metabolizability of different lipid sources in the diet of Japanese quail at the laying phase. The quail were distributed in a completely randomized design with ten replications of seven poultry per treatment, totaling six treatments: basal feed (control) and basal feed containing 10% soybean oil, corn oil, canola oil, sunflower oil, and poultry fat. The values of nitrogen-corrected apparent metabolizable energy (AMEn) and the metabolizability coefficient (MC%) were evaluated. No significant difference was found between the different lipid sources for AMEn (kcal/kg) and MC (%). The value of metabolizable energy corrected for nitrogen for soybean oil was 8,790 kcal/kg; 8,773 kcal/kg for corn oil; 8,784 kcal/kg for canola oil; 8,788 kcal/kg for sunflower oil; and 8,681 kcal/kg for poultry fat in laying Japanese quail. The digestibility coefficients were 93.88% for soybean oil, 93.53% for corn oil, 93.32% for canola oil, 93.74% for sunflower oil, and 93.06% for poultry fat.

This study aims to evaluate the residual effect of different lipid sources in the diet of Japanese quails (Coturnix japonica) in the rearing phase on the performance and egg quality in the initial phase of egg-laying. In the first stage, 400 Japanese quails aged 21 days were used, being distributed in a completely randomized experimental design, with five treatments and ten replicates of eight birds/replicate Treatments consisted of basal ration (BR) with 2.5% soybean oil; BR with 2.5% corn oil; BR with 2.5% cottonseed oil; BR with 2.5% sunflower oil; and BR with 2.5% canola oil.At 42 days, maintaining the initial design, all quails received a basal ration with soybean oil, in order to evaluate the residual effect of the previous phase on the performance and egg quality in the initial phase of egg-laying (43 - 84 days). The different lipid sources did not affect the performance of quails in the initial phase of production. For egg quality, yolk height, yolk diameter, yolk index, gravity, and Haugh unit (HU) showed better results in the treatment using sunflower oil. There was a residual effect of the use of lipid sources of vegetable origin in the rearing phase diet of Japanese quails on egg quality traits. Lipid sources from soybean, corn, cottonseed, canola, and sunflower seeds can be used as energy sources in the rearing diet of egg-laying quails for not being harmful to their initial performance. The longevity in egg production of quails fed with different lipid sources in the rearing phase was similar.
A pesquisa foi conduzida com objetivo de avaliar o efeito residual de diferentes fontes lipídicas na dieta de codornas japonesas (Coturnix japonica) na fase de recria sob o desempenho e a qualidade de ovos na fase inicial de postura. Na primeira etapa foram utilizadas 400 codornas japonesas com idade de 21 dias, as aves foram distribuídas em tratamentos seguindo um delineamento inteiramente casualizado com dez repetições, de oito aves, em cinco tratamentos: ração basal (RB) com 2,5% de óleo de soja, RB com 2,5 % de óleo de milho, RB com 2,5% de óleo algodão, RB com 2,5% de óleo de girassol e RB com 2,5% de óleo de canola. Aos 42 dias mantendo o delineamento inicial, todas aves receberam ração basal com óleo de soja, para que fosse avaliado o efeito residual da fase anterior sobre o desempenho e a qualidade dos ovos na fase inicial de postura (43 - 84 dias). As diferentes fontes lipídicas não afetaram o desempenho das aves na fase inicial de produção. Para a qualidade dos ovos, os parâmetros de altura, diâmetro e índice de gema, gravidade e UH foram melhores no tratamento com utilização de óleo de girassol. Houve efeito residual da utilização de fontes lipídicas de origem vegetal na dieta em fase de recria de codornas japonesas sobre as características da qualidade dos ovos. As fontes lipídicas oriundas das sementes de soja, milho, algodão, canola e girassol podem ser utilizadas como ingredientes energéticos na dieta de recria de codornas poedeiras por não serem prejudiciais ao desempenho inicial das aves. A longevidade na produção dos ovos das aves alimentadas com diferentes fontes lipídicas na fase de recria foi semelhante.

This study aims to evaluate the effects of the inclusion of different homoeopathic products on the diet of laying quails. We used 200 Japanese quails (Coturnix coturnix japonica) distributed in a completely randomized design consisting of the adoption of four experimental diets, with eight replicates of five quails each. The treatments were control (without additives), calcium carbonate (vehicle used in the products), Fertsigo®, and Ovosigo®. We determined the performance, egg quality, and blood biochemical profile of quails. The data were submitted to Tukey test at 5% probability. There was a significant effect of the homeopathic products Fertsigo® and Ovosigo® on the variables egg weight, yolk, albumen, and shell percentage. It did not affect the performance and blood biochemical profile (p > 0.05). The addition of the homoeopathic product Ovosigo® and FertSigo® in diets of Japanese quails at the laying phase is recommended because they resulted in the better weight of the egg and its components. Thus, the application of homoeopathy in the production of quails is a viable practice, since it is easy to manage, has a reduced cost, and exerts positive effects on the performance of quails.
Este estudo teve por objetivo avaliar a ação da inclusão de diferentes produtos homeopáticos na dieta de codornas poedeiras. Foram utilizadas 200 codornas japonesas (Coturnix Coturnix Japonica), distribuídas em delineamento inteiramente casualizado, consistindo na adoção de quatro dietas experimentais com oito repetições de cinco codornas cada. Os tratamentos foram: Controle (sem aditivos); Carbonato de cálcio (veículo utilizado nos produtos); Fertsigo® e Ovosigo®. O desempenho, a qualidade dos ovos e o perfil bioquímico do sangue das codornas foram avaliados e os dados submetidos ao teste de Tukey ao nível de 5% de probabilidade. Houve efeito significativo do produto homeopático Fertsigo® e Ovosigo® para as variáveis peso do ovo, gema e albúmen e porcentagem de casca. Não foram afetados o desempenho e o perfil bioquímico do sangue (p > 0,05). É indicada a adição dos produtos homeopáticos Ovosigo® e FertSigo® em dietas para codornas japonesas na fase de postura, pois resultaram no melhor peso do ovo e seus componentes. Assim, a aplicação da homeopatia na produção de codornas pode ser uma prática viável, pois é de fácil administração, com custo reduzido e com efeitos positivos no desempenho das codornas.

This study aimed to evaluate the influence of homeopathic products in diets of quails in the egg quality when submitted to different storage periods. In the trial we used 200 Japanese quails in a completely randomized design with 4 diets: reference diet, vehicle used in homeopathic products and 2 homeopathic products - Fertsigo® and Ovosigo® with ten replicates of three eggs in each. Egg quality parameters were evaluated during 3 storage periods. Data were evaluated as repeated measures in time, the effects of the interactions between treatments and time as well as their isolated effects were verified. There was the interaction between homeopathic products and storage time in the parameters of albumen and yolk height, Haugh unit, and yolk index, in which a reduction was obtained over time. For egg weight, yolk, albumen and shell, percentage of albumen, and percentage of eggshell there was a significant effect only for homeopathy. The inclusion of homeopathic additives increased egg weight. It is indicated the addition of the product with homeopathic basis Ovosigo® and FertSigo® in diets of Japanese quails in the laying phase resulting in better egg and components but did not influence the quality maintenance of eggs of Japanese quails in the periods evaluated.(AU)
