Performance Parameters, Plasma Lipid Status, and Lymphoid Tissue Fatty Acid Profile of Broiler Chicks Fed Camelina Cake AncaG HăbeanuM LefterNA RopotăM 2019 <div><p>ABSTRACT The effects of dietary camelina cake (CAMC) on broiler chicks’growth performance, plasma lipid status and fatty acid profile (FA) of lymphoid organs were evaluated. Six hundred broilers (3-week-old, Cobb 500) were randomly allotted for 20 days in a feeding trials into 2 groups: control (C; corn-soybean meal-canola meal basal diet) and experimental (CAMC; 80 g CAMC/kg diet replaces canola meal from C diet). Blood samples (n=12/group) were collected on day 42 for plasma profile analysis (glucose, Glu; total cholesterol, TC; high-density lipoprotein cholesterol, HDL-C; low-density lipoprotein cholesterol, LDL-C; triglycerides) and immune organs (spleen, thymus, bursa of Fabricius) for FA analysis. The FA profile of lymphoid tissue was determined by gas chromatography. Feeding the CAMC diet did not influence broilers performance parameters or relative weights of lymphoid tissue, except the weight of bursa that decreased (p<0.05). Plasma lipids profile was affected by decreasing (p<0.05) the concentrations of Glu, TC, HDL-C and LDL-C in broilers fed the CAMC diet. In all lymphoid tissue, the total content of n-3 polyunsaturated fatty acids (PUFA) increased (p<0.001) and the total level of n-6 PUFA decreased (p<0.001) as the effect of the CAMC diet. The n-6:n-3 ratio decreased (p<0.001) up to 5:1 in all lymphoid tissue. The higher (p<0.05) concentration of arachidonic acid was found in the spleen, followed by the thymus and the bursa of the chicks fed the CAMC diet. Our results indicate that feeding 80 g/kg camelina cakes in broiler chicks finisher diet had no negative impact on productivity, beneficially alter the plasma lipid status and fatty acids profile of lymphoid tissue.</p></div>
