Canola oil and organic selenium in quail diets: fatty acid profile, cholesterol content and external egg quality

Abstract: <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 Se… Show more

“…However, studies have shown that the addition of 2–6% rapeseed oil to the diet of laying hens reduces egg production, egg weight, feed intake, and the feed-to-egg ratio [ 12 , 82 , 150 ]. In general, the addition of 2–6% rapeseed oil to the diet of laying hens exerts a limited effect on conventional parameters of egg quality, such as albumen weight, egg yolk weight, albumen height and, therefore, HU [ 12 , 13 , 83 , 84 , 150 , 153 ]. The addition of rapeseed oil might increase the lipid content and composition of the egg yolk and increase the contents of oleic acid, linolenic acid, DHA, and total n − 3 PUFAs in eggs, but it does not significantly change the cholesterol content [ 11 , 13 , 150 ].…”
