Antimicrobials Use in Broiler Chicken Breeding: Case of the Ain Defla Province (Algeria)

Abstract

The objective of this study is to assess the use of antimicrobials in the broiler production in Algeria, through a survey completed by private veterinarians of the Ain Defla province. In this context, 65 band breeding were studied for antimicrobial use between October 2019 and June 2020. The results showed that all of the studied bands received antimicrobial treatments for at least 5 days during the breeding period. Quinolones class was the most widely used class of antimicrobials (24.4%), followed by the tetracyclines class (22.5%), sulfonamides (20.1%) and polypeptides (12.1%). Macrolides and beta-lactams come last (4.02% and 3.22% respectively). 160 mg of active compound were administered per kg of chicken meat produced. The number of daily doses (nDDkg) was 10.5, while the treated live weight (nCDkg) was 2.66. Per molecule, chickens were more exposed to colistin, doxycycline, oxytetracycline and enrofloxacin. The withdrawal period of used bands was not respected, and meat from these treated broilers was found to contain antimicrobial residues at 33.9%. The reasons for this frequent use are various: poor conditions and bad practices of breeding, poor quality of day-old chicks, veterinary practices, and difficulties of control by veterinary authorities.

Consumption habits of broiler offal and its contamination by antibiotic residues in the Northeast of Algeria

“…These results are consistent with those reported in Algeria by Mokhtar Rahmani et al [27] and with those reported in Morroco by Chaiba et al…”

“…The liver is considered a palatable offal with known benefits for the body. In Iran, the liver is traditionally the most consumed offal and is considered a quality source of protein [19,27]. The liver is rich in vitamins A, B, and D [28] and contains minerals and trace elements such as iron and zinc [14].…”

Response of Antibiotic Resistance Genes and Related Microorganisms to Arsenic during Vermicomposting of Cow Dung

“…The results showed that the absolute abundance of most ARGs in the vermicompost products was reduced to different degrees compared with that in the initial cow dung, indicating that earthworms had a reducing effect on some antibiotic resistance determinants, which is consistent with the results of Han et al [ 33 ]. Furthermore, sulfonamide resistance genes ( sul -ARGs) were most abundant in the initial substrate of cow dung, followed by tetracycline resistance genes ( tet -ARGs) ( Figure 4 ), which may be due to the widespread use of sulfonamides and tetracyclines in animal breeding [ 34 ].…”

Designing a professional request of the regional farming community for information-analytical, consulting and research services of agricultural education

“…For example, the authors of the article S.A. Mohammed, B.A.J. Ridha talk about the need to attract the attention of farmers to protecting the environment of rural areas from pollution [5]. A significant number of chemicals and fertilizers are used in agricultural production, the unsystematic use of which can significantly worsen the environmental situation in rural areas.…”
