Resumo

This study has aimed to assess the effect of increasing levels of annatto (Bixa orellana L.) seed meal (AM) on yolk pigmentation and the sensory analysis of eggs of common quails fed sorghum-based diets when compared tocorn. Eighty female common quails (Coturnix coturnix coturnix) in the laying phase were used, being them aged from 251 to 316 days. There were three experimental periods of 21 days each (251-272; 273-294; 295-316 days). The quails were distributed in a completely randomized design with five treatments (T1 - corn-based feed; T2 - feed with 100% of sorghum instead of corn without the addition of AM; T3, T4, and T5 - feed with 100% of sorghum replacing corn with the addition of 0.5, 1.0, and 1.5% AM, respectively) and four repetitions. One hundred eggs from each treatment were used for analysis. Sensory evaluation was applied with an untrained panel with 20 evaluators. The eggs were boiled, peeled, and served. The panelists assessed the appearance, flavor, color, aroma, texture, and overall evaluation of the eggs. Annatto seed meal added to sorghum-based diets promoted linear increases in appearance, flavor, color, aroma, texture, and overall evaluation, evaluated during the sensory analysis (p=0.001). The addition of 1.5% AM in the sorghum-based diets of the common quails benefited the characteristics of appearance (4.50), flavor (4.50), color (4.55), aroma (4.25), and texture (4.55) of the assessed quail eggs, being considered more attractive and with greater acceptance (overall evaluation = 5.97) in relation to the other treatments tested. The inclusion of AM in the sorghum-based diets improved the yolk pigmentation of quail eggs in relation to the control treatments. The AM triggers positive effects on yolk pigmentation and sensory characteristics of common quail eggs.(AU)


Objetivou-se avaliar o efeito de níveis crescentes do farelo do resíduo da semente de urucum (Bixa orellana L.) (FU), sobre a pigmentação da gema e análise sensorial dos ovos de codornas europeias alimentadas com dietas à base de sorgo em substituição ao milho. Foram utilizadas 80 codornas europeias (Coturnix coturnix coturnix) fêmeas, na fase de postura, no período de 251 a 316 dias de idade. Foram três períodos experimentais de 21 dias cada (251-272; 273-294; 295-316 dias). As codornas foram distribuídas em delineamento inteiramente casualizado, com cinco tratamentos (T1 - ração à base de milho; T2 - ração com 100% de sorgo em substituição ao milho sem a adição de FU; T3, T4 e T5 ­ ração com 100% de sorgo em substituição ao milho com a adição de 0,5; 1,0 e 1,5% de FU) e quatro repetições. Cem ovos de cada tratamento foram utilizados para a análise. A avaliação sensorial foi aplicada em painel não treinado de 20 avaliadores. Os ovos foram cozidos, descascados e servidos. A aparência, sabor, cor, odor, textura e avaliação global, foram avaliadas pelos painelistas. A farinha de semente de urucum adicionada à ração à base de sorgo promoveu aumentos lineares nos atributos aparência, sabor, cor, odor, textura e avaliação global, avaliados durante a análise sensorial (p=0,001). A adição de 1,5% de FU em dietas a base de sorgo beneficiou as características de aparência (4,50), sabor (4,50) cor (4,55), aroma (4,25) e textura (4,55) dos ovos de codorna avaliados, sendo considerados mais atrativos e com maior aceitação (avaliação global = 5,97), em relação aos demais tratamentos testados. A inclusão do FU nas rações à base de sorgo melhorou a pigmentação da gema dos ovos de codorna em relação aos tratamentos controle. O AM desencadeia efeitos positivos na pigmentação da gema e nas características sensoriais de ovos de codornas comuns.(AU)

Resumo

The objective of the present study was to evaluate production and egg quality as well as the intestinal morphometry of laying hens fed diets supplemented with marine microalga Dunaliella salina. Six hundred laying hens were allocated based on a completely randomized design into five treatments (0, 0.25, 0.50, 0.75, and 1% inclusion of D. salina biomass) with 12 replicates of 10 hens per treatment. The experiment was divided into three periods of four weeks each, totaling 84 days. During this period, the productive performance of laying hens, the physical-chemical quality of the eggs, and the morphometric alterations of the small intestine and liver were determined. The inclusion levels of D. salina biomass had a linear effect on the performance (egg weight, egg mass, and feed conversion), qualitative parameters (yolk weight and yolk index), and physicochemical parameters of eggs (total carotenoids, TBARS, and yolk color). At the same time, villi lengths and the villus:crypt ratio of the duodenum and ileum segments and the metabolization of carotenoids in the liver were increased as an effect of Dunaliella salina dietary supplementation. Thus, the inclusion of marine microalgae D. salina biomass in experimental diets for laying hens improves the performance, the intestinal health, the physical-chemical quality of the eggs, and at the same time increases carotenoid content and improves egg oxidative stability.(AU)

This study was conducted to evaluate the effects of paprika and marigold extracts on the productivity of Japanese quails, quality and sensorial analysis of eggs. Japanese quails were allocated in a completely randomized design and factorial arrangement 2 × 2 + 1, and four replicates. Diets were formulated based on: 1) corn (control), and 2) sorghum (S) without pigments, 3) S + 0.06% paprika extract (PE), 4) S + 0.01% marigold extract (ME), and 5) S + 0.06% PE and 0.01% ME. There was no effect of the control and factorial interaction on feed intake, egg-laying rate, or egg mass; however, the feed: gain ratio was lower among quail fed with diets containing both extracts. The inclusion of PE and ME in the diets improved the feed: gain ratio and yolk color; the inclusion of PE reduced the feed intake and specific weight of the eggs. Compared to the control, treatments based on sorghum or sorghum + PE led to a difference in egg taste and yolk color in the sensorial visit the website to get the how analysis. It was concluded that paprika and marigold extracts could be included in quail diets because of improvements in feed: gain ratio and yolk color.


Este estudo foi conduzido para avaliar os efeitos dos extratos de páprica e marigold sobre a produtividade de codornas Japonesas, qualidade e análise sensorial dos ovos. Codornas Japonesas foram alocadas em delineamento completamente ao acaso e arranjo fatorial 2 × 2 + 1, e quatro repetições. As dietas foram formuladas baseadas em: 1) milho (controle) e 2) sorgo (S) sem pigmentos, 3) S + 0,06% de extrato de páprica (EP), 4) S + 0,01% de extrato de marigold (EM) e 5) S + 0,06% EP + 0,01% EM. Não houve efeito da interação controle e fatorial sobre consumo de ração, taxa de postura ou massa de ovo; entretanto, a conversão alimentar foi menor entre codornas alimentadas com dietas contendo ambos os extratos. A inclusão de EP e EM nas dietas melhorou a conversão alimentar e a cor de gema; a inclusão de EP reduziu o consumo de ração e o peso específico dos ovos. Comparado com o controle, os tratamentos baseados em sorgo ou sorgo + EP levaram à diferença no sabor do ovo e na cor da gema na análise sensorial. Concluiu-se que os extratos de páprica e marigold poderiam ser incluídos em dietas para codornas por melhorar a conversão alimentar e a cor de gema.

ABSTRACT Water lentils (Duckweed [DW])(Lemna gibba), in irrigation ponds, was evaluated by replacing two levels of soybean meal (SBM) on performance and egg quality of laying hens of 54 weeks of age. A total of 72 white Lohmann laying hens were randomly allocated into 3 treatments with 6 replicates/treatment, 4 hens/replicate in a randomized complete block design. Treatments were: control group (DW0%) with (SBM) as the main source of protein, T1 (DW10%) and T2 (DW20%), where duckweed replaced 10% and 20% of SBM for 9 weeks. No significant differences were observed among the dietary treatments in body weight change, feed conversion ratio, egg weight and mortality rate. Replacement with (DW20%) decreased (p 0.05) feed intake, egg laying rate and egg mass. The dry albuminin (DW10%) decreased (p 0.05) from 7 to 9 weeks and in the total period. Yolk pigmentation was highly (p 0.001) improved by the replacement. Blood spots were increased (p 0.05) with (DW20%). Duckweed grown in good quality irrigation water can replace up to 10% of the SBM as a source of protein without adverse effects on hen performance and egg quality in addition to profitability.

Two experiments were conducted to evaluate the nutritional quality of two sources of low-oil distiller's dried grains with solubles (DDGS) and their pigmenting ability for broiler chicken skin and egg yolks. In Experiment 1, 360 Bovan-White hens between 69 and 77 weeks of age were randomly assigned to five dietary treatments with 6 replicates of 12 hens each. In Experiment 2, 375 Ross 308 broiler chickens were randomly assigned to five treatments with three replicates of 25 birds each. The chickens were fed the experimental diets from one to 42 d of age. In both experiments, treatments consisted of a basal diet with no DDGS, and diets with 6% or 12% inclusion of DDGS from two sources. In Experiment 1, no significant differences in performance were detected among treatments (p> 0.05). Egg yolk pigmentation, according to CR-400 Minolta Colorimeter redness (a) and yellowness (b), linearly increased (p 0.05) with DDGS inclusions. In Experiment 2, no significant differences (p>0.05) were detected among treatments in growth performance, carcass yield, or abdominal fat at 42 d of age. Yellowness linearly increased (p 0.05) in the skin and abdominal fat of the birds that consumed diets with DDGS. The results of the current study indicate that feeding two sources of low-oil DDGS to broiler chicks or laying hens does not negatively affect egg production or growth performance while improves egg yolk and skin yellowness.(AU)

Resumo

O grão seco de destilaria com solúveis (DDGS) é um coproduto da indústria de etanol do milho e pode ser utilizado na alimentação animal, como substituto do farelo de soja. Foram realizados dois experimentos com o objetivo de avaliar diferentes níveis de inclusão de DDGS de milho na dieta de codornas e galinhas poedeiras, sobre o desempenho, qualidade dos ovos, pigmentação da gema e análise econômica. No experimento 1, foram utilizadas 210 codornas poedeiras (Coturnix japonica) com 23 a 31 semanas de vida, distribuídas em delineamento inteiramente casualizado com cinco tratamentos e seis repetições, com sete aves por unidade experimental. No experimento 2, foram 150 galinhas poedeiras (Hisex Brown) com 54 a 62 semanas de vida, distribuídas em delineamento interiramente casualizado com cinco tratamentos e seis repetições, com cinco aves por unidade experimental. Os tratamentos utilizados nos dois experimentos foram: ração controle; inclusão de 5% de DDGS; inclusão de 10% de DDGS; inclusão de 15% de DDGS e inclusão de 20% de DDGS. As variáveis avaliadas foram: consumo de ração, conversão alimentar por dúzia e massa de ovos, produção de ovos, peso dos ovos, peso da gema, albúmen, variação do peso corporal, viabilidade das aves, gravidade específica, coloração da gema, componente do ovo e análise econômica. No experimento 1, para as variáveis consumo individual, conversão alimentar por massa de ovos, taxa de postura, gravidade específica e e coloração da gema pelo leque colorimétrico houve efeito com a inclusão do DDGS (P<0,05), para as demais variáveis não houve efeito significativo. No experimento 2, para as variáveis coloração da gema pelo leque colorimétrico e colorimetro digital (L* e a*) houve efeito linear com a inclusão do DDGS (P<0,05), para as demais variáveis não foi observada diferença significativa. Quanto à análise econômica, o DDGS pode ser considerado um alimento alternativo pelo baixo custo (R$). O DDGS de milho tem o potencial pigmentante na gema do ovo, fazendo com que apresente mais amarela sem influenciar o desempenho e a qualidade dos ovos das galinhas e codornas poedeiras, além de ser um produto mais econômico.


Dry distillers grain with Solubles (DDGS) is a Coproduct of ethanol corn industry and can be used in animal nutrition, as a substitute for soybean meal. Two experiments were conducted to evaluate different levels of inclusion of DDGS of cornmaize in the diet of laying hens and Japanese quail, about the performance, eggs quality, yolk pigmentation and economic analysis. In experiment 1, 210 were used laying quail (Coturnix japonica) with 23 to 31 weeks of life, distributed in completely randomized design with six treatments and five replicates, with seven quail per experimental unit. In experiment 2, were 150 laying hens (Hisex Brown) with 54 to 62 weeks of life, distributed in entirely randomized design with six treatments and five replicates, with five birds per experimental unit. The treatments used in two experiments were: T1: ration control; T2: inclusion of 5% of DDGS; T3: inclusion of 10% of DDGS; T4:15% inclusion of DDGS; T5: inclusion of 20% of DDGS. The variables evaluated were: feed intake, feed conversion per dozen and mass of eggs, egg production, egg weight, weight variation, viability of birds, gravity specifies, coloring of the yolk, egg component and economic analysis. The data were subjected to analysis by linear and quadratic regression models, the 5% probability. In experiment 1, to the individual consumption and feed conversion ratio by mass of eggs there was quadratic effect with the inclusion of DDGS (P < 0.05), for gravity and egg weight, egg yolk, and gem coloration for range and colorimetric digital colorimeter (b *) effect with the inclusion of DDGS (P < 0.05), for the other variables had no significant difference. In experiment 2, for the variables weight of yolk, albumen and bark, and gem coloration for range and colorimetric digital colorimeter (L *) there was no linear effect with the inclusion of DDGS (P < 0.05), the other variables had no significant difference. As the economic analysis the DDGS can be considered an alternative food for low cost (R$). The DDGS of corn has the potential pigmentante in egg yolk, making present more yellow mainly to higher levels, without affecting the performance and eggs quality of hens and laying quails, as well as being a more economic product.

Consumer demands for healthy foods have stimulated the research on the use of natural products in animal nutrition. Annatto can be used a pigmentation source to improve yolk color of commercial eggs. This study aimed at evaluating the effects of the inclusion of ground annatto seeds on the performance and egg quality of layers fed sorghum-based diets. A total of 336 40-w-old hens were distributed according to randomized blocks into seven treatments with six replicates of eight birds each. The following treatments were applied: T1- egg production feed based on corn and soybean meal; T2- egg production feed based on sorghum and soybean meal; T3, T4, T5, T6, and T7- egg production feed based on sorghum supplemented with 0.5, 1.0, 1.5, 2.0, and 2.5% ground annatto seeds, respectively. As to performance parameters, only egg production was influenced, with hens fed the corn-based diet producing more eggs than those fed the sorghum-based diet with inclusion of 1.5 and 2.5% de annatto. The only egg quality parameter affected by treatments was the color of yolk, which pigmentation increased with increasing levels of ground annatto seeds. It is concluded that ground annatto seeds can be supplemented in sorghum-based production feeds for layers, and that the inclusion level of 0.89% is sufficient to promote the same yolk pigmentation as that obtained with corn-based diets.
