Investigation of Antibiotic Residues in Poultry Products in Meknes – Morocco
نویسندگان
چکیده
Antibiotics are used in poultry farms to enhance growth, feed efficiency and reduce diseases. However, their irrational and non-moderate using can cause serious problems for the consumer and the manufacturer. The aim of this study is to estimate antibiotics residues in poultry (chicken and turkey) tissues collected from broiler farms in Meknès Morocco. For this purpose, 120 poultry meat samples (muscle, liver, gizzard and eggs samples) were taken from various farms and tested by conventional microbiological methods (four plates) recommended and approved by French Agency of Food Safety (AFSSA). For muscle samples suspected positive to antibiotic residues at screening, quantitative evaluation for determination of these molecules was performed using liquid chromatography-mass spectrometry (HPLC-UV-MS) (Delepine and HurtaudPessel, 2002). The results revealed that 36.15% of poultry meat samples from intensive livestock Original Research Article Chaiba et al.; JAMB, 2(1): 1-8, 2017; Article no.JAMB.31567 2 were positive to antibiotic residues. As for samples from traditional livestock, all samples were negative. The concentrations of tetracycline in these samples does not exceed the maximum residue limits of both FAO and WHO, which is 100 μg / Kg. Indeed, the levels obtained vary between 37 and 74 μg / kg.

The Potential of Tropical Agro-Industrial by-Products as a Functional Feed for Poultry
Following the ban of synthetic antibiotics as antimicrobial agents and growth promoters, poultry nutritionists are now trying to find antibiotic substitutes. Agro-industrial by-products are abundant in tropical countries and have been used as the alternatives to conventional feedstuffs in poultry rations. These by-products are also known to contain several bioactive compounds such as oligosacch...
