“…Pelícia (2008) stated the major portion of the absorbed phosphorus is incorporated into the yolk during the process of egg formation in the form of phospholipids and phosphoproteins; therefore, a change in the availability of this nutrient could reduce the percentage yolk. These results agree with the results cited by Costa (2010), who evaluated the effect of calcium and phosphorus levels in diets of 45-57-week-old Japanese quails, and found no effect of calcium levels (2.2, 2.6, 3.0, 3.4, and 3.8%) on the percentage of albumen and yolk, but found a significant effect on yolk weight.…”

“…According to Oliveira and Almeida (2004), quails are more tolerant to calcium variations, and excrete excess of this mineral more efficiently compared to other species. Similar results were found by Pizzolante et al (2007), who tested diets containing different levels of calcium (1.25%, 2.50%, and 3.75%) in 54-week-old Japanese quails; Costa (2010), evaluated the effect of calcium levels (2.2%, 2.6%, 3.0%, 3.4%, and 3.8%) in the diets of 45-57-week-old Japanese quail; . and Silva (2011) tested levels of 2.0%, 2.5%, 3.0%, and 3.5% calcium in 39-54-week-old Japanese quails.…”

“…High calcium levels could reduce food intake. This can be explained by the fact that quails regulate calcium intake similar to the regulation of energy and protein (COSTA, 2010). In the present study, we did not observe reduced food consumption.…”

“…According to the literature, there may be interference from high levels of calcium in the calcium phosphorus ratio. According to Scherer et al (2004) and Costa (2010), excess calcium in the diet may interfere with the availability of other minerals, such as phosphorus. Pelícia (2008) stated the major portion of the absorbed phosphorus is incorporated into the yolk during the process of egg formation in the form of phospholipids and phosphoproteins; therefore, a change in the availability of this nutrient could reduce the percentage yolk.…”

“…Higher levels of calcium caused a reduction of shell thickness. The supply of Ca above the recommended levels can improve the quality of the eggshell in the final third of the production cycle (COSTA, 2010). However, according to Maiorka and Macari (2002), when in excess, absorption and consequently utilization might be impaired because, according to Simões (2009), the kidneys increase calcitonin elimination through the urine, stimulating its deposition in bone and reduced intestinal absorption.…”

The goal of the present study was to evaluate the influence of increasing levels of dietary calcium on performance, egg quality, and the amount of calcium retained in the meat and excreted by Japanese quails at the final production. Four hundred 46-58-week-old Japanese quails were distributed in a completely randomized design consisting of five calcium level treatments: T1 = 2.95%, T2 = 3.25%, T3 = 3.55%, T4 = 3.85% and T5 = 4.15% calcium. The performance variables included feed intake (g bird -1day -1 ), egg production (%), feed conversion by egg mass and per dozen eggs, egg mass (g), and viability. For egg quality, we assessed egg weight, percentage of albumen, yolk weight, percentage of shell, and shell thickness. We also evaluated the amount of calcium present in the meat and the amount of calcium excreted by quails. Increasing levels of calcium linearly influenced feed conversion, weight of yolk, and percentage of eggshell. Shell thickness increased up to the 3.85% calcium treatment. Calcium content of the meat differed among the quails; the quails fed the lowest level of calcium (2.95%) showed higher calcium content in meat, whereas calcium excretion increased with increasing levels of calcium in the diet. In conclusion, the addition of 3.85% of calcium in quail feed at the end of production improved eggshell quality, and maintained internal quality and performance within the recommended standards for the production phase tested in quails. Levels higher than 3.85% calcium negatively influenced the parameters analyzed. Key words: Coturnix coturnix japonica. Digestibility. Eggshell thickness. ResumoO objetivo do presente estudo foi avaliar a influência de níveis crescentes de cálcio na dieta sobre o desempenho, a qualidade do ovo, e a quantidade de cálcio retido na carne e excretado por codornas japonesas em final da produção. distribuídas em um delineamento experimental inteiramente casualizado, sendo os tratamentos constituídos de cinco níveis de cálcio: T1 = 2,95%, T2 = 3,25%, T3 = 3,55%, T4 = 3,85% e T5 = 4,15%. As variáveis de desempenho incluíam o consumo de ração (g/ave/dia), produção de ovos (%), conversão alimentar por massa de ovo e por dúzia de ovos, massa de ovo (g), e viabilidade. Para a qualidade dos ovos foram avaliados o peso dos ovos, porcentagem de albúmen, peso da gema, porcentagem de casca e espessura da casca. Também foi avaliada a quantidade de cálcio presente na carne e a quantidade de cálcio excretado pelas codornas. O aumento dos níveis de cálcio influenciou linearmente a conversão alimentar, o peso de gema e a porcentagem de casca de ovo. A espessura da casca aumentou até o nível de inclusão de 3,85% de cálcio. O teor de cálcio da carne diferiu entre as codornas; as codornas alimentadas com o menor nível de cálcio (2,95%) apresentaram maior teor de cálcio na carne, enquanto a excreção de cálcio aumentou com o aumento dos níveis de cálcio na dieta. Em conclusão, a adição de 3,85% de cálcio na alimentação de codornas no final da produção melhorou a qualidade da casca do ovo, e...

Spirulina platensis in Japanese quail feeding alters fatty acid profiles and improves egg quality: Benefits to consumers

et al. 2019

View full text Add to dashboard Cite

The aim of this study was to investigate whether microalgae in Japanese quail feed alters performance, fatty acid profiles in the eggs and egg quality. One hundred quails were distributed in four groups and five replicates of five birds per experimental group. The treatments consisted of four levels of Spirulina platensis microalgae (0%, 5%, 10%, and 15%) in the diets. We evaluated the productive performance and chemical‐physical characteristics of eggs, the oxidant/antioxidant status in egg yolks, and the fatty acid profile in the diet and egg yolks. Microalgae in the diet did not influence egg production; however, it increased the yolk index as well as the color intensity of the yolk. Saturated and polyunsaturated fatty acid levels decreased in egg yolks, and monounsaturated fatty acid levels increased in the yolks. Lipid peroxidation levels were lower and total antioxidant capacity was higher in egg yolks of quails receiving microalgae in the diet. Practical applications Microalgae in quail diets improves egg quality and provides benefits to consumer health, acting as an antioxidant and immune‐stimulant. Microalgae in quail diets had positive effects on egg quality. This is because it reduced levels of saturated fatty acids that are undesirable, and increased monounsaturated fatty acid levels that are beneficial to the health of consumers. Finally, antioxidants increased in egg yolks, consequently reducing lipid peroxidation.

A nutrição desempenha importante papel na obtenção de bons índices produtivos e de tecido ósseo de qualidade nas aves. Inúmeros nutrientes da dieta influenciam diretamente o crescimento, a manutenção óssea e a qualidade de ovos, destacando-se o cálcio (Ca) e o fósforo (P). O esqueleto consiste no reservatório de Ca e P do organismo e nas poedeiras essa função é particularmente importante, uma vez que a casca do ovo contém aproximadamente 10% do Ca corporal total da ave. Assim, há alta demanda de Ca para manter a homeostase sanguínea, concomitantemente à formação da casca. Mecanismos fisiológicos controlam a integridade do esqueleto em resposta às diferentes necessidades da vida produtiva da ave de postura. Na presente revisão foram apresentadas informações técnicas e fisiológicas acerca do Ca e do P para codornas japonesas em postura. Foram verificadas diferenças nas recomendações nutricionais de Ca e P disponível (Pdisp) para codornas japonesas, decorrentes dos seguintes fatores: fonte e disponibilidade biológica dos minerais, idade das aves, capacidade absortiva e nível de energia das dietas.
