Artemisia annua L. aqueous extract as an alternative to antibiotics improving growth performance and antioxidant function in broilers

Abstract

Due to a series of problems, such as drug resistance and tissue residue caused by adding antibiotics to feed, this research aimed to study the effects of Artemisia annua L. aqueous extract (AAE) as an alternative to antibiotics on growth performance and antioxidant capacity of broilers. A total of 240 one-day-old mixed-sex Arbour Acres broilers were randomly allotted into six groups with five replicates of eight birds each. These six diets were formulated by adding 0, 500, 1000, 1500, 2000 mg/kg AAE and 50 mg/kg chlortetracycline (CTC) to the basal diet, respectively. Average daily body weight gain (ADG), average daily feed intake (ADFI), and feed conversion ratio (FCR) were measured. Total antioxidant capacity (T-AOC), the activity of catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) and the concentrations of malondialdehyde (MDA) were determined, and the relative gene expression in tissues was measured. The polyphenol flavonoid contents and in vitro antioxidative results showed that: the total phenolic and flavonoid contents were 39.58 ± 6.01 mg GAE/g, 7.04 ± 0.55 mg RE/g, respectively. The inclusion of AAE increased ADG, the activities of T-AOC, CAT, SOD and GSH-Px, and the gene expression of antioxidant enzymes, the concentrations of MDA decreased in serum and tissues. In conclusion, AAE can be used as a feed additive due to its capability to improve growth performance, antioxidant function in broilers. Dietary inclusion of 1000-1500 mg/kg AAE can be used as an alternative for antibiotic growth promoter replacement without negative effect on broiler performance. HIGHLIGHTS Artemisia annua L. aqueous extract can promote growth performance and antioxidant function of Broilers. Artemisia annua L. aqueous extract is expected to become the substitute for antibiotics and promote the growth of the body. The optimal dose range of Artemisia annua L. aqueous extract in diet of broilers was 1000-1500 mg/kg.

“…After harvesting, the proline and soluble protein contents of the leaves of four plants randomly selected from each treatment were immediately determined via spectrophotometry using commercial kits (Nanjing Jiancheng Institute of Bioengineering, Nanjing, China) [ 46 ].…”

Response of Japanese quails (Coturnix coturnix japonica) to dietary inclusion of Moringa oleifera essential oil under heat stress condition

“…With an aim to eliminate the adverse effects of stress, in 1940, the use of subtherapeutic doses of antibiotics was introduced to the poultry sector. However, the development of antimicrobial resistance in consequence of the mis-dosage of antibiotics, the public wellness risks associated with antibiotic residues in meat, and consumer demands have all caused the forbidden of the use of antibiotics as feed admixture in food-producing animals (Tekce and Gul 2016;Attia, Bakhashwain, et al 2018;Attia, El-Naggar, et al 2019;Guo et al 2020).…”

Hesperidin and Naringin Improve Broiler Meat Fatty Acid Profile and Modulate the Expression of Genes Involved in Fatty Acid β-oxidation and Antioxidant Defense in a Dose Dependent Manner

“…Post-mortem lipid hydroperoxidation and protein oxidation (e.g., oxymyoglobin to metmyoglobin) have significant effects on meat tenderness and color [ 64 , 65 , 66 ]. GSH as an antioxidant may play a considerable role in preserving the shelf life and quality of meat products [ 67 ]. This role may be compared with that of vitamin E [ 68 ].…”
