effect of diet supplemented with graded levels of ginger (zingiber officinale) powder on growth performance, hematological parameters, and serum lipids of broiler chickens

the present study was conducted at the poultry research center, faculty of agriculture; sebha university, libya. the feeding trial lasted 42 days in total. a local hatchery provided 240 unsexed one-day-old broiler chicks (ross 308). the birds were randomly distributed into four groups, and each group was then divided into four replicates, with 15 birds in each group. the objective of the current study was to examine the impact of ginger powder as a natural feed supplement on broiler chickens’ growth performance, hematological parameters, and serum lipids. four dietary treatments were formulated and supplemented with ginger powder at levels 0%, 0.2%, 0.4% and 0.6%. the findings exhibited substantial differences in body weight and weight gain across the experimental groups. birds fed ginger-enriched diets had higher feed conversion and lower feed intake than control birds (p 0.05). birds fed a 0.6% ginger powder diet compared to the control group had considerably superior productive performance (p 0.05), while feed consumption was lowered. dietary ginger powder supplementation improved hematological parameters; white blood cells, lymphocytes, heterophils, and the lymphocyte to heterophil ratio were improved with dietary ginger powder supplementation (p 0.05). additionally, as compared to the control group, ginger powder groups significantly (p 0.05) lowered serum triglycerides, total cholesterol, and very low-density lipoprotein. while supplementation of dietary ginger powder significantly increased (p 0.05), the levels of high-density lipoprotein against the control group. in conclusion, ginger supplementation had a positive effect on the performance of chickens when supplemented on broiler ration and can be considered an alternative growth promoter in feeding broiler ration.
