The effect of dietary supplementation of flaxseed oil and ginger powder on lipid profiles, thyroid hormones and liver enzymes in broiler hens

The aim of this study was to investigate the effect of flaxseed oil and ginger powder on lipid profiles, thyroid hormones and liver enzymes of elderly broiler breeders. For this purpose the Number of 200 female Ross 308 broiler breeders by 45 weeks of age used in a completely random factorial design (2×4) including 2 levels of ginger (zero and 1.5%) and two levels of flax (zero, 1, 2 and 3%) as long as 10 weeks in 5 experimental treatments 5 replications and 5 hens per replication were performed. The results showed that consumption of ginger, flaxseed oil and co-consumption of ginger with flaxseed oil had no significant effect on triglycerides, cholesterol, HDL and glucose (p<0.05).LDL concentration decreased in birds fed with 1.5% ginger powder (p<0.05). using 1.5% ginger powder in the ratio decreased aspartate aminotransferase enzyme, while, feeding flaxseed oil and co-consumption feeding of flaxseed oil and ginger oil had no significant effect on in control treatment group (p<0.05). Consumption of ginger, flaxseed oil and concomitant consumption of flaxseed oil and ginger reduced the enzyme alanine aminotransferase compared to the group receiving zero levels of ginger and zero flaxseed oil (p<0.05). Using ginger and flaxseed oil in the diet had no significant effect on thyroid hormones (p<0.05). Adipose tissue and liver parameters didn’t significantly affected by flaxseed and ginger oil (p<0.05). To wrap up, the results of present study revealed that, supplementing the mother's diet with 1.5% ginger and 2% flaxseed oil has a positive effect on liver enzymes.
