Effect of Graded Levels of Biochar Supplementation as a Growth Promoter on Productive and Physiological Performance of Broiler Chicks

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 2 nd , 3 rd , 4 th , 5 th , and 6 th 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.

Effectiveness of feeding different biochars on growth, digestibility, body composition, hematology and mineral status of the Nile tilapia, Oreochromis niloticus

“…According to Mabe et al 63 , Cyprinus carpio when fed bamboo BC showed no changes in growth indices; however, their serum quality had improved, suggesting better overall fish health. Elghalid 64 found that hematological traits such as Hb, RBCs and hemocytosis percentage (HCT%) improved when chicks were given diets containing 0%, 1%, 2%, 4%, 6%, or 8% biochar. According to Dim et al 65 , when BC was given to Meleagris gallopavo (turkey) at 5 g kg −1 , 15 g kg −1 and 25 g kg −1 , 15 g kg −1 , showed significant improvements in RBC, HCT, Hb, and WBC.…”

Impact of feeding biochar sources in rohu (Labeo rohita): Evaluating the growth, nutrient absorption, carcass composition, haematology and mineral status

“…Although detailed assessments regarding the haematology of several fish species fed with biochar sources are relatively rare, emphasizing the importance of the current work. However, its effects on different animal species have been evaluated such as Elnaggar et al (2022) reported that varying amounts of biochar had a significant influence on blood parameters in broiler chicks as compared to the control. The findings are consistent with the results of Dim et al (2018), who discovered that using biochar (6%) in broiler feed substantially ( p < 0.05) boosted RBCs, WBCs, PLT and other metrics.…”
