“…The obtained values are compatible with those of second-cycle layers (Table 2). These results are different from those of Costa et al (2008), who found a linear effect of different soybean oil levels on egg production, whereas canola oil did not influence this parameter. Rodrigues et al (2005) found that egg production decreased when soybean oil was not supplemented in the feed, and that it increased as soybean oil was included in the diet, being the highest at the maximum level of soybean oil inclusion (8%).…”

“…Some authors did not find any differences in the performance of layers fed different oil sources (Yu & Sim, 1987;Hargis et al, 1991;Nash et al, 1996). Costa et al (2008) did not observe worse performance in heavy layers fed a diet containing 2% linseed oil as compared to those fed a control diet based on corn and soybean meal. Also, Baucells…”

A trial was carried out at the Animal Science Department of the Federal University of Viçosa to evaluate the performance of heavy and light layers. During four periods of twenty-eight days, 432 layers in the second production cycle, being 216 Hy Line W36 (light birds) and 216 Hy Line Brown (heavy birds), were used. A completely randomized experimental design with a 1+(4x2x2) factorial arrangement (one control treatment, four oil sources, two inclusion levels, and two genetic lines) with four replicates of six birds per experimental unit, was applied. The treatments consisted of diets containing 16.5% crude protein, formulated to supply the nutritional requirements, and the inclusion of each oil source at 2 or 4%. Soybean, canola, linseed and fish oils were used. The control diet did not contain any oil. The studied parameters were: feed intake (g/hen/day), egg production (%), egg weight (g), egg mass (g/hen/day), feed conversion ratio (kg feed /dozen of eggs and per kg eggs). Oil levels and sources did not influence egg mass, feed conversion ratio (per kg eggs and dozen eggs), or egg production. During the first three periods, independently of oil source or genetics, eggs from layers fed 4% oil were the heaviest, except for those of light birds fed soybean oil during the third period, which egg weight was similar for the 2 and 4% levels. Light layers presented lower feed intake and better feed conversion ratio (per kg eggs and dozen eggs) as compared to heavy layers, and there was no influence of the evaluated oil sources on feed intake

“…When oil is added to the diet, the fatty acid synthesis is reduced and the bird has more energy for productive performance (Costa et al, 2008). However, although the levels of methionine, linoleic acid and oil have increased with the inclusion of canola meal in the diet, egg weight showed an increasing quadratic response up to the level of 30% of canola meal, with subsequent reduction.…”

This study evaluated the effect of different levels of canola meal in the diet to laying Japanese quails on productive performance, egg quality and economic viability. A total of 120 80-day-old Japanese quails (Coturnix coturnix japonica) with average weight 146.54 ± 12 g were evaluated during 84 days. Dietary treatments consisted of the replacement of soybean meal with canola meal at 0, 10, 20, 30, 40 or 50%. We evaluated economic viability, productive performance, internal and external quality of eggs. Data were analyzed by polynomial regression at 5%. Body weight decreased linearly as the level of canola meal increased (p = 0.0055). Egg weight (p = 0.0032) and diameter (p = 0.0398) showed a quadratic response, increasing up to 30% substitution with subsequent reduction. Yolk color increased linearly as the level of canola meal increased (p = 0.0039). Canola meal can substitute soybean meal up to 30% without impairing productive performance, egg quality and diet cost.Efeito do farelo de canola na dieta de codornas japonesas RESUMO. Este estudo avaliou o efeito de níveis dietéticos de farelo de canola para codornas japonesas em postura sobre o desempenho produtivo, a qualidade dos ovos e a viabilidade econômica. Foram utilizadas 120 codornas japonesas (Coturnix coturnix japonica) com peso médio de 146,54 ± 12 g e 80 dias de idade foram avaliadas por 84 dias. Os tratamentos foram constituídos de níveis de substituição do farelo de soja pelo farelo de canola em 0, 10, 20, 30, 40 ou 50% na dieta. Foi avaliada a viabilidade econômica, o desempenho produtivo, a qualidade interna e a externa dos ovos. Os dados foram analisados por meio de regressão polinomial com 5% de significância. O peso corporal diminuiu linearmente com o aumento do nível de farelo de canola (p = 0,0055). O peso do ovo (p = 0,0032) e o diâmetro (p = 0,0398) apresentaram respostas quadráticas, aumentando até o nível de 30% de substituição e reduzindo posteriormente. A cor da gema aumentou de forma linear com o aumento do nível de farelo de canola (p = 0,0039). O farelo de canola pode substituir o farelo de soja em até 30% sem prejudicar o desempenho produtivo, qualidade do ovo e custo de dieta. Palavras-chave: alimento alternativo, nutrição, desempenho, proteína.

“…Sim & Bragg (1977), Holland et al (1980), Hargis et al (1991) e Mori et al (1999) descreveram que a inclusão de óleos vegetais ricos em ácidos graxos poliinsaturados na ração de poedeiras pode reduzir a concentração de colesterol na gema e no plasma. No entanto, os resultados encontrados na literatura são contraditórios (Costa et al, 2008).…”

RESUMO -Foram estudados os efeitos de duas fontes de óleo vegetal, de carvão e de vitamina E sobre o desempenho e os níveis lipídicos do sangue e dos ovos de poedeiras comerciais. Utilizaram-se poedeiras Lohmann Brown e Lohmann LSL com 58 semanas de idade. O experimento teve duração de 84 dias, divididos em três períodos de 28 dias, e foi realizado em delineamento inteiramente casualizado em esquema de parcelas subdivididas, tendo nas parcelas um esquema fatorial 8 × 2, com oito dietas e duas marcas comerciais, e nas subparcelas os períodos. Para avaliação das características produtivas, colesterol total, triglicérides e HDL sanguíneos, utilizaram-se quatro repetições de seis aves por unidade experimental e, para determinação do colesterol total das gemas, duas repetições. As dietas foram acrescidas de 2,0% de óleo de soja ou de linhaça em combinação ou não com vitamina E (60 mg/kg de ração) e/ou carvão (2,0%). Os resultados não evidenciaram diferenças entre as dietas experimentais sobre as variáveis de desempenho. Consumo de ração, espessura da casca, colesterol total e triglicerídios no sangue foram influenciados pelas marcas comerciais e peso médio dos ovos, espessura da casca, colesterol total e triglicerídios no sangue, pelos períodos experimentais. O uso de óleos vegetais, carvão e vitamina E nas dietas experimentais não influencia as características de desempenho nem o perfil lipídico do sangue e de colesterol total da gema dos ovos. Aves Lohmann LSL apresentam maiores consumos de ração e níveis mais altos de colesterol e triglicérides no sangue.Palavras-chave: características produtivas, gema, lipídios sanguíneos Evaluation of oil, vegetal charcoal and E vitamin on performance and on blood and egg lipid concentrations of laying hens ABSTRACT -This experiment was carried out to evaluate the effects of two vegetal oils sources, charcoal and vitamin E on performance and lipid levels in blood and eggs of commercial laying hens. It was used Lohman Brown and Lohman LSL laying hens at 58 weeks of age. The experiment lasted 84 days split in three 28-day periods and it was carried out in a complete random design in a split-plot scheme, in a 8 × 2 factorial scheme in the plots with eight diets an two commercial brands, and the periods in the subplots. For evaluation of productive characteristics, total cholesterol, blood tryclecydes and HDL, it was used four repetitions of six birds per experimental unit and, for determination of total yolk cholesterol, two repetitions were used. Diets were added with 2% soybean oil or linseed oil combined or not with E vitamin (60 mg/kg ration) and/or charcoal (2%). No diet effects on the performance variables were observed. Commercial strain effects on feed intake, shell thickness, total cholesterol and blood triglycerides and experimental period effects on egg weight, shells thickness, total cholesterol and blood triglycerides were observed. Use of vegetal oil, charcoal and vitamin E in experimental diets do not affect characteristics of performance neither blood lipid and egg ...
