“…In a similar study (Grobas et al, 2001) the effects of different levels of tallow, olive oil, soy oil and flax seed oil on the performance of laying hens were investigated and it was reported that all supplementations decreased feed intake compared to the control; the weight of eggs numerically increased in the soy oil supplemented group; egg production was higher in the experimental group with the exception of the soy oil supplemented group; feed conversion was not affected from supplementation. The data obtained from the present study were consistent with some research findings that reported a decrease for weight of egg (Cherian, 2008;Mazalli et al, 2004a;Nobakht et al, 2011), egg production (Agah et al, 2010), feed intake (Çelebi and et al, 2010). The findings of the present study were in Utlu, 2006;Shafey et al, 2003) and feed conversion agreement with the findings of Ceylan et al (2011).…”

“…Another study (Mazalli et al, 2004a) was the effects of different feed oils o n the performance in laying hens were investigated, determined that Polyunsaturated Fatty Acids (PUFA) decreased the weight and size of eggs and regulated the concentration of plasma estradiol by reducing estrogenic activity. In another study where the different levels of locally produced canola seeds were used in the diet of laying hens (Agah et al, 2010), it was observed that feed intake, egg production and the weight of eggs decreased in parallel with an increase in the level of canola seed. The cause of decrease in egg weight is the lack of linoleic acid in the diet (Rasaulpour et al, 2011;Nobakht et al, 2011).…”

“…The fatty acid composition of fats used in poultry diets is reflected as well in animal products. Being rich in omega-3 fatty acids (Mazalli et al, 2004a;Fouladi et al, 2008a;Agah et al, 2010), canola oil also increases the amount of omega-3 in the form of alphalinoleic fatty acid (Fouladi et al, 2008b) in egg and animal tissue; the presence of omega-3 in the diet of food animals improves the taste of animal meat and increases the ratio of canola oil in these animals (Sarica, 2003). Canola oil has what is now considered to be an almost perfect balance of n-6 to n-3 PUFA; the n-6 to n-3 ratio in canola oil is 2:1 which perfectly randomly to receive one of four diets containing 0.0, 2.0, matches human requirements.…”

The effects of different levels of canola oil (0.0, 2.0, 4.0 and 6.0%) on the performance, egg shell quality and fatty acid composition of laying hens were investigated in the present study. A total of 96 chickens consisting of 24 chickens in each group were used in the four groups. Feed and water were offered as ad libitum. Egg production was recorded daily, while feed intake was recorded weekly. Egg quality criteria were determined in 12 eggs from each group. The egg yolk fatty acid profile was determined with gas chromatography. The use of increasing levels of canola oil decreased egg production, egg weight and daily feed intake (in group including 6.0% canola oil, 70.98%, 61.68g, 109.52g respectively), although these mentioned parameters increased in the control group according to the other canola oil groups and conversely did not affect the feed conversion. In addition, supplementation of canola oil increased the yellow colour of the eggs and the egg-yellow index. On days 21 TBARS (Thiobarbituric Acid Reactive Substance) value significantly increased depending on increasing levels of canola oil (13.60, 14.78, 16.68, respectively), while on days 42 TBARS value did not change. The egg yolk lipid profile was not significantly difference in the canola oil groups, conversely decreased a very small amount of in the control group. The blood serum lipid profile decreased in the canola oil groups according to the control group. In the same time, monoaçildigliserol also decreased in the canola additive groups. In parallel with increasing levels of canola oil (42.94, 42.14 and 43.51%, respectively), monounsaturated fatty acid (oleic acid) in the egg yolks significantly increased compared to the control group (36.05%). On the basis of the results, we concluded that canola oil supplementation into the diet of laying hens is important in producing monounsaturated fatty acid (MUFA)-rich functional eggs.

“…This result shows a possible potentiation effect of SeO on egg weight in the presence of canola oil. Agah et al (2010) observed that the weight of eggs decreased with an increase in the level of canola seed in the diet. This decrease in egg weight is attributed to the reduction in linoleic acid in the diet (RASOULPOUR et al, 2011).…”

<p>Foram estudados os efeitos da substituição parcial ou total do óleo de soja (SO) por óleo de canola (CO), suplementado ou não com selênio orgânico (SeO) na dieta de codornas (Coturnix coturnix coturnix) sobre o perfil de ácidos graxos, o colesterol na gema e a qualidade externa dos ovos. Um total de 252 codornas foram alimentadas durante três períodos de 28 dias cada, utilizando seis tratamentos: Controle (SO); SO + 0,3ppm SeO; Óleo de canola (CO); CO + 0,3ppm SeO; ½ SO + ½ CO; ½ SO + ½ CO + 0,3ppm SeO. O delineamento foi inteiramente casualizado e as médias dos tratamentos foram comparadas por contrastes ortogonais e teste de Duncan a 5%. Observou-se um aumento significativo de 4% nos níveis de ácido oleico na gema dos ovos com a suplementação de óleo de canola, em comparação com os demais tratamentos. A suplementação de SeO não alterou o perfil de ácidos graxos da gema. Nem o óleo de canola nem a suplementação de SeO afetaram o colesterol da gema. O peso do ovo foi maior nas aves alimentadas com CO suplementado com 0,3ppm SeO comparado com CO não suplementado, mas não diferindo dos demais tratamentos. Conclui-se do experimento que a substituição de SO por CO na dieta das codornas muda o perfil de ácidos graxos na gema, aumenta a concentração de ácido oleico e diminui o ácido linoleico, sem afetar outras características de qualidade do ovo.</p>

“…O óleo de peixe é a melhor fonte de AGPs n-3 eicosapentaenóico (AEP) e docosahexaenóico (ADH) (HOSSEINI-VASHAN et al, 2011). No corpo humano, o ácido α-linolênico (18:3 n-3, AAL) é metabolizado para AEP e ADH (AGAH et al, 2010;SIMOPOULOS, 2000;HOSSEINI-VASHAN et al, 2011;NAIN et al, 2012). A maioria dos benefícios para a saúde está relacionada ao AEP e ao ADH (TRAUTWEIN, 2001).…”
