Use of different carriers in the production of extruded flaxseed and its effect on yield, egg quality, blood metabolites and blood lipid indices in laying hens LSL strain

This study was conducted to evaluate the use of different sources in the extruded flaxseed production and its impact on the performance of laying hens and the quality of egg trays.In this experiment LSL laying hens in a completely randomized design with 9 treatments, 5 replicates and 10 hens in each replicate at the age of 34 to 42 wk-old. Experimental control treatment standard diet based on corn and soybean, treatments flaxseed full fat with 7.5 and 15% ration levels, treatments flaxseed full fat and soybean meal with 7.5 and 15% diet ration, treatments flaxseed full fat and sunflower meal with 7.5 and 15% diet ratios, treatments flaxseed full fat and corn gluten 7.5 and 15% diet rations. The results showed that using 7.5 and 15% full-fat flaxseed and corn gluten and 15% full-fat flaxseed and soybean meal improved the units (P<0.05). The highest shell weight was observed in treatments containing full-grain flaxseed and corn gluten, the difference was significant (P>0.05). Blood metabolites analysis showed that the number of white blood cells in the treatments containing full fat flaxseed and corn gluten significantly was different from the other treatments (P<0.05). But there was no significant difference in the number of heterophiles, monocytes and eosinophils (P>0.05). The results of this study showed that the use of 7.5 and 15% of extruded flax and corn gluten increases the yield and improves the quality of eggs.
