The Effect of Flaxseed oil and Ginger Powder on Fat Metabolism, Lipid Profiles and Liver Enzymes of Broilers

Extended Abstract Introduction and Objective: One of the major problems of mother herd industry is the accumulation of abdominal fats and increasing plasma fat index by furthering production period. These changes predispose chickens and roosters to metabolic diseases and fertility issues. The aim of this study was to investigate the effect of flaxseed oil and ginger powder on fat metabolism, lipid profiles and liver enzymes of broilers. Material and Methods: we used 72 pieces of Ross 308 broiler mother rooster by 45 weeks of age, in a completely randomized factorial design (4×2) including 2 levels of ginger powder (consisting 0 & 1.5 percent of ratio), 4 levels of flaxseed oil. (0, 1, 2 and 3percent of ratio) as long as 10 weeks in 8 experimental treatments with 3 replicate and 3 roosters per replication. Results: The results of present study revealed that consumption of ginger powder and flaxseed oil significantly reduced the triglyceride and plasma cholesterol concentrations in broiler compared to the control group (p<0.05).  Also, interactions of different levels of ginger powder and flaxseed oil on triglyceride and total plasma were significant (p<0.05). Consumption ginger powder significantly reduced low-density lipoproteins and increased high-density lipoproteins of blood plasma (p<0.05), while flaxseed oil and the simultaneous effects of ginger powder and flaxseed oil had a significant effect on low density lipoproteins (LDL). And did not have any significant effect on high density lipoproteins (HDL) (p<0.05).  The Glucose concentration didn’t affect by ginger powder and flaxseed oil and also the interaction effects of ginger powder and flaxseed oil (p<0.05). Using 1.5% of ginger powder in diet decreased aspartate aminotransferase enzyme (p<0.05), while using flaxseed oil and simultaneous consumption of flaxseed oil and ginger powder had no significant effect on aspartate aminotransferase enzyme (p<0.05). The main effect of ginger powder, flaxseed oil and the interaction effects of ginger powder and flaxseed oil in reducing plasma alanine aminotransferase were also significant (p<0.05). Liver weight, relative liver weight and abdominal fat weight, relative weight of abdominal fat weight didn’t affect by ginger powder and flaxseed oil and the simultaneous effects of ginger and flax (p<0.05). Conclusion: Based on the results of the present study, supplementation of the mother rooster diet simultaneously with a level of 1.5% ginger powder and the level of 2% flaxseed oil had positive effect on lipid profile and liver enzymes.
