The presence of antibacterial in 97 pork and 83 chicken meat samples, randomly collected from 3 different representative provinces (Hanoi, Hai Duong and Thai Binh) of the Red River Delta, was determined by a screening step using in parallel 2 microbiological methods (Premi®-test and New Two Plate Test). In total, 27% of all samples displayed a positive response in at least one of both tests, from which 11 (13% of chicken samples) are chicken samples and 38 (39% of pork samples) are pork samples. The 33 samples from the Thai Binh which were screened positive were then submitted to post-screening tests specific for tetracyclines and (fluoro) quinolones (Tetrasensor® dipstick for tetracyclines and an ELISA for quinolones), two groups of antibiotics widely used in animal production in this region, and confirmed by liquid chromatography coupled to mass spectrometry. Tetracyclines and (fluoro)quinolones residues were found, using a post screening test, in 23 and 5 samples, respectively. Ten (all pork) and 4 samples (1 pork, 3 chicken) were confirmed containing tetracyclines (chlortetracycline, oxytetracycline, tetracycline, doxycycline) and (fluoro) quinolones (nalidixic acid, enrofloxacin and ciprofloxacin) respectively, from which 1 and 3 pork samples were found to contain enrofloxacin and tetracycline residues , respectively, with a concentration higher than their respective MRLs. This study shows the good performance of the proposed strategy to identify non-compliant meat samples (microbiological screening, tetracyclines and quinolones targeted post-screening and confirmation), which allows to obtain conclusive results in 82% of the cases.

In Vietnam where epidemics occur regularly in animal production, the farmers consider antibiotics as one of the solutions to fight against livestock diseases, thus the risk of abuse, even illegal use of antibiotics in livestock is very high. However, this is a recent issue and has not yet been thoroughly investigated. A cross-sectional study on the use of antibiotics in pig and poultry production as well as the farmer’s knowledge on the danger of the antibiotic use in three different animal production systems (farm household, semi-industrial and industrial) was conducted from July 2009 to March 2010 on 270 entities, in 3 representative localities of the Red River Delta (RRD). The results showed that a large volume of antibiotics was used arbitrary in all animal production systems. Animals were not only treated for acute diseases, but also for disease prevention, and for growth promotion. At least 45 antibiotics of more than 10 classes were used. Fifteen antibiotics were used in pig and poultry feed. For diseases treatment and prevention, antibiotics were used abusively and even illegally (e.g. chloramphenicol) by both farmers and veterinarians. The findings of this survey will permit developing new strategies for prudent use of antibiotics in livestock in Vietnam. These results will help not only to strengthen issues such as veterinary networks; antibiotics use guidance, residues monitoring systems and food safety, but also to improve awareness and ethics of producers and veterinary drug sellers.

In the context of the valorization of poultry biodiversity, this work represents a step toward a better knowledge of the production abilities of local chicken breeds in Vietnam. Local chicken breeds are indeed particularly well suited for low-input rearing systems, as widely practiced in rural households of Vietnam. The socio-economic importance of these breeds might be underpinned by a market valorization through the mounting of differentiated quality value chains. Such a strategy needs the production potential of these local breeds to be assessed using parameters of egg quality and quantity. This study presents data about egg quality traits in two chicken breeds, the Ri and the Mia. The former is the most widespread breed in Vietnam, while the latter is known to be in danger of extinction. Nineteen parameters of quality of ninety eggs of Ri chickens and sixty eggs of Mia chickens were measured, each for both 40 and 60-weeks old hens to take hens ages into account.Mean egg weight of Mia eggs (44.70g) was significantly (p<0.001) higher than that of Ri eggs (41.68g). The yolk to albumen ratio was not significantly different (p>0.05) between the two breeds at the age of 40 weeks (Ri: 0.55; Mia: 0.58). For 60-weeks old hens, the ratio became significantly (p<0.05) higher in Mia eggs compared to Ri eggs (0.64 vs. 0.57). No significant difference (p>0.05) was recorded between the two breeds for parameters used for egg freshness assessment (Haugh’s units and pH of albumen and yolk) or eggshell resistance (maximal breakage force). Despite the small sample available for the study (due to the low availability of Mia hens and eggs), significant differences in egg quality traits were thus observed between these two breeds.

Dans le contexte de valorisation de la biodiversité avicole, ce travail se propose de poser les bases d’une réhabilitation des poules locales Vietnamiennes, particulièrement adaptées aux conditions d’élevage peu intensives de ce pays. La grande importance socioéconomique et culturelle de ces races pourrait être renforcée et exploitée à des fins de développement rural par la promotion de filières de qualités différenciées. De telles évolutions nécessitent de caractériser le potentiel de production de ces races sur le plan qualitatif. Cette étude a pour objectif l’étude de la qualité des œufs des races de poules vietnamiennes Ri et Mia. La première est la poule la plus répandue au Vietnam et la deuxième est une race menacée d’extinction. Dix neuf caractères de qualité externe et interne de 90 œufs de la poule Ri et 60 œufs de la poule Mia ont été mesurés à 40 et à 60 semaines. Le poids entier moyen des œufs de la Mia (44,70g) était significativement (p<0,001) supérieur à celui de la poule Ri (41,68g). Le rapport jaune/blanc n’était pas significativement (p>0,05) différent à l’âge de 40 semaines (Ri : 0,55 ; Mia : 0,58). À l’âge de 60 semaines, ce rapport devient significativement supérieur pour les œufs Mia alors que celui des œufs Ri (0,64 vs. 0,57 ; p<0,05). Aucune différence significative (p>0,05) n’a été enregistrée entre les deux races pour les paramètres de fraîcheur des œufs (unités d’Haugh et pH des blancs et des jaunes) et de résistance des coquilles (force maximale de rupture). Malgré le faible effectif de cette étude, des différences significatives entre les performances de production ont été observées entre ces deux races phénotypiquement et génotypiquement proches.
