RESUMO

Objetivou-se avaliar a pigmentação de gemas de ovos de poedeiras alimentadas com produto comercial (PC), à base de cantaxantina e óleo de sementes de urucum. Utilizaram-se 240 poedeiras comerciais com 55 semanas de idade, que receberam cinco diferentes rações: controle (RC) à base de milho e farelo de soja, RC com dois níveis (70 e 140 ppm) do PC e RC com dois níveis de mistura entre pigmentantes comerciais sintéticos Carophyll® Yellow e Red (20 + 10 ppm) e (15 + 30 ppm) e quatro repetições de 12 aves cada. Foram avaliados o desempenho e a cor das gemas, que foi avaliada utilizando o leque colorimétrico. Não houve efeito sobre o desempenho das poedeiras, exceto para a cor da gema, que apresentou interação dos pigmentantes nos diferentes períodos de avaliação. Aos sete dias de fornecimento, houve estabilização da pigmentação, com uso de 70 ppm do produto comercial, enquanto as gemas oriundas dos ovos das aves que receberam a inclusão de 140 ppm estabilizaram a cor aos 14 dias do fornecimento. O produto comercial à base de cantaxantina e óleo de sementes de urucum é eficiente na pigmentação da gema de ovos em rações à base de milho amarelo.(AU)


The aim of this study was to evaluate the egg yolk pigmentation of laying hens fed commercial powdered products (CPP) based on canthaxanthin and urucum seed oil. A total of 240 commercial laying hens at 55 weeks of age were used, which received five different rations: control (CR) based on corn and soybean meal, CR with two levels (70 and 140 ppm) of CPP and CR with two levels of mixture between synthetic commercial pigments Carophyll® Yellow and Red (20 + 10 ppm) and (15 + 30 ppm), and four replicates of twelve birds each. The performance and color of the yolk were evaluated, using the colorimetric fan. There was no effect on the performance of the laying hens, except for the color of the yolk, which showed interaction of the pigmentants in the different periods. At seven days of supply there was stabilization of pigmentation with use of 70 ppm of the commercial powdered product, while egg yolks from hens receiving the inclusion of 140 ppm stabilized color at 14 days of delivery. The commercial product based on canthaxanthin and urucum seed oil is efficient in egg yolk pigmentation in yellow maize based diets.(AU)

RESUMO

The objective of this study was to evaluate the inclusion of powder cinnamon in the diet of Japanese quails, regarding their performance and egg quality. A total of 360 quails, 18 weeks old, were distributed in a completely randomized design with five treatments and six replicates of 12 animals. The experimental period lasted 84 days. The treatments were the inclusion of 0; 3.0; 6.0; 9.0 and 12.0 g kg-1 of cinnamon powder in the diet. The performance and quality of eggs produced were evaluated. A sensorial analysis of the eggs was carried out to evaluate the color of the egg yolk, the taste of the egg and the purchase intention. There was no significant effect on the performance and egg quality variables, except for the specific gravity and color of the yolk, which increased linearly. The evaluators presented a higher intention to purchase eggs from the treatment with 6g kg-1 of cinnamon addition in the diet. We concluded that the inclusion of 12.0 g kg-1 of cinnamon powder in the diet for laying quail does not affect the performance and the taste of the eggs, nevertheless, this level of inclusion provides an improvement in the specific gravity and color of the yolk.

RESUMO

Objetivou-se avaliar o desempenho e a qualidade dos ovos de galinhas poedeiras Negras Avifran alimentadas com a inclusão de 0,8% de cada extratos vegetais pigmentantes, extrato de páprica (Capsicum annuum), de flor de marigold (Tagetes erectus) e 0,045 % de pigmentante sintético (cantaxantina) na ração. Utilizou-se 120 poedeiras Negras Avifran distribuídas em 4 tratamentos, 6 repetições com 5 aves cada, totalizando 24 parcelas experimentais, criadas em sistema livre de gaiolas. Foram realizadas análises de desempenho, qualidade dos ovos e cor da gema do ovo através de dois métodos de cores (leque colorimétrico e calorímetro digital). Os dados foram submetidos à análise de variância e as médias comparadas pelo teste Tukey a 5% de probabilidade. Não houve influência dos aditivos vegetais sobre os parâmetros de desempenho e qualidade dos ovos (P>0,05), apenas para a variável cor da gema houve efeito significativo (P0,05).


The objective was evaluate of the performance and egg quality of laying hens Avifran Black fed with the inclusion of 0.8% of plant extracts pigmentation solutions, extract of paprika (Capsicum annuum), flower marigold (Tagetes erectus) and 0.045% of synthetic pigmentante (canthaxanthin) in the feed. Were used 120 layers Avifran Black distributed in 4 treatments, 6 replicates with 5 birds each, totaling 24 experimental units, in cage-free system. Performance analyses were quality of the eggs and egg yolk color through two methods (fan colorimetric and digital calorimeter). The data were submitted to analysis of variance and Tukey test compared to 5% probability. There was no influence of plant additives on the parameters of performance and eggs quality (P>0.05), only for the yolk color there was a significant effect (P0.05).

A inclusão de 0,8% de pigmentantes naturais na dieta de poedeiras Negras Avifran pode ser utilizada como forma de substituir a cantaxantina, pois proporciona maior coloração da gema do ovo, favorecendo sua comercialização, e não prejudica o desempenho e a qualidade interna e externa dos ovos (P>0,05).(AU)

The inclusion of 0.8% of natural pigmentation solutions in the diet of laying hens Avifran Black can be used as a way to replace the canthaxanthin as it provides increase color of egg yolk, favoring your marketing, and does not affect the performance and quality internal and external (P>0.05).(AU)
