Abstract
This study aimed to determine the effects of graded amounts of biochar supplementation on broiler chick production index, lipid profile, biomarkers of antioxidant status, carcass characteristics, and economic efficiency. A total of 216, seven-day-old, unsexed broiler chicks (Arbor Acres) were divided into six experimental groups (36 chicks each), each with six replicates (6 chicks each). The first group was fed the basal diet and served as control; while the 2nd, 3rd, 4th, 5th, and 6th groups were fed the basal diet supplemented with 1, 2, 4, 6, and 8 % biochar, respectively. According to the data, treatment groups that added biochar levels of 1, 2, 4, and 6 % outperformed the control group in terms of productivity, economic efficiency, and production index. While it was at the same previous levels, total lipids, triglycerides, cholesterol, low-density lipoprotein (LDL), and malondialdehyde (MDA) were lowered. When compared to the control group, there were higher levels of glucose, thyroid hormones (T3-T4), high-density lipoprotein (HDL), total antioxidant capacity (TAC), and glutathione peroxidase (GSH-Px), and superoxide dismutase (SOD) (within normal range). In conclusion, it can be concluded that adding biochar to the diet at levels of 1, 2, 4, and 6 % improved the physiological status and growth performance of broilers without having any negative impacts on the blood parameters of broiler chicks.
