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

Abstract

Introduction: 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 egg quality.
Materials & Methods: 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 2and3
extruded flaxseed with 7.5 and 15% ration levels, treatments4 and 5, extruded flaxseed and
soybean meal with 7.5 and 15% diet ration, treatments 6 and 7, extruded flaxseed and sunflower
meal with 7.5 and 15% diet ratios, treatments8 and 9 extruded flaxseed and corn gluten 7.5 and
15% diet rations.
Results: The use of 7.5 and 15% of extruded flax and corn gluten significantly increased laying
rate, feed consumption, conversion ratio and production percentage (P<0.05). Consumption of
7.5 and 15% of extruded flax and corn gluten as well as 15% of extruded flax and soybean meal
improved the Hav unit (P<0.05). The highest shell weight and endurance were observed in eggs
produced in treatments containing extruded flax and corn gluten (P<0.05). The number cells,
hematocrite, hemoglobin and lymphocytes in treatments containing 7/5 and 15 % corn gluten
had a significant increase compared to the control group (p<0/05). Heterophil, monocytes and
eosinophils cells were not affected by experimental treatments (P<0.05). Cholesterol and
triglyceride levels were significantly reduced in treatments eight and nine (P<0.05). Treatments
did not affect total blood protein concentration (p>0.05).
Conclusion: 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.
