BACKGROUND Feeding innovation occurs when individuals choose a novel, unknown type of food and/or acquire new feeding skills. Here we studied feeding innovation and social transmission of the new feeding habit in canaries. Adult canaries eat a wide variety of seeds but avoid larger ones such as those of sunflowers. We determined whether adults of both sexes(More)
Incurred samples from a pig treated with ampicillin, one of the most important penicillin antibiotic drugs used in food-producing animal treatments, were analyzed at the residue level of the drug in muscle tissue (approximately 100 microg kg(-1)) during their freezing storage and using three different techniques: quantitative microbiological assay, HPLC-UV(More)
The processes involved in the social transmission of recognition and consumption of hemp seeds were investigated in juvenile canaries (Serinus canarius). The combined influences of observation of a parent feeding, presence of parent and accessibility of seeds on future seed consumption were investigated in six experimental conditions (each employing 15(More)
The influence of interactions between young canaries (Serinus canarius) and adults on the onset latency of detection, picking up, husking, and eating of seeds was studied in 90 juveniles canaries, aged 28 days, and fed no seeds after their first flight from the nest. The following factors were studied: the ability to cat with the adults, the observation of(More)
We studied the factors that enhance food recognition and consumption in young canaries when confronted with adults. In contrast to previous studies on canaries, in which social transmission of food habits was studied in the context of dyadic interactions (one juvenile–one adult), we proposed a more realistic framework in which young canaries were studied in(More)
To identify processes involved in the choice of ethanol by adult Drosophila, flies homozygous Adh(F), reared in the absence of alcohol were placed in contact with: a) an ethanol-free medium, b) a medium containing ethanol, c) a medium supplemented with 4-methylpyrazole (4-MP, an inhibitor of the ADH pathway), d) a medium containing ethanol and 4-MP. The(More)
The results of an in-house laboratory validation of a microbiological method for the screening of antibiotic residues in milk are presented. The sensitivity of this five-plate test, called Screening Test for Antibiotic Residues (STAR), was established by the analysis of milk samples spiked with 66 antibiotics at eight different concentrations. Ten different(More)
