1. Laying hen performance and yolk fat fatty acid (FA) concentrations were evaluated with respect to the inclusion in the diet of different sources and levels of marine fish oil (MFO). 2. Twelve diets were arranged factorially, with three sources (MFO1, MFO2_EPA, MFO3_DHA) and four levels of inclusion (15, 30, 45 and 60 g/kg) of MFO. 3. Type of diet had(More)
1. Laying hen performance, yolk fat fatty acid concentrations and firmness of eggs were evaluated with respect to the inclusion in the diet of conjugated linoleic acid (CLA) and fish oil. 2. Nine diets were arranged factorially, with three levels of supplementation of CLA (1, 3 and 5 g/kg) and fish oil (0, 14 and 20 g/kg). 3. Type of diet did not affect egg(More)
because less ingredient is used to meet the birds requirements. This is equivalent to an annual savings of up to $266 million to the Brazilian broiler and broiler-breeder producers. Diets formulated with HOC had a lower crude protein content than with traditional corn, and potentially could reduce annual nitrogen excreted to the environment by 5.3 Mtonnes.(More)
(1) Laying hen performance, yolk fatty acid (FA) concentrations, sensory quality and firmness of eggs were evaluated with respect to the inclusion in the diet of conjugated linoleic acid (CLA) and high-oleic acid sunflower oil (HOSO). (2) Nine diets were arranged factorially, with three concentrations of CIA (0, 1 and 2 g/kg) and HOSO (10, 20 and 30 g/kg).(More)

A marine algal oil (MAO) with a high docosahexaenoic acid content (46.7%) was evaluated for the production of n-3 fatty acid (FA) enriched eggs. To determine its effects, laying hens were fed one of two diets containing different amounts of MAO, or a control diet containing marine fish oil (MFO). The efficiency of retention of total n-3 FA in the yolk fat(More)
