No full textTwo consecutive experiments were performed on 150 male muscovy ducklings in order to evaluate the effects of 3 mg/kg of Clenbuterol supplemented in the diet. In experiment 1 one group of birds (group A) administered for 16 days has a withdrawal period of 3 days, another (Group B) received the Beta-agonist for 19 days till the day of slaughtering and a third (Group C) served as control. In experiment 2, birds of Group A had a longer withdrawal period (9 days) and birds of Group B received Clenbuterol for 25 days. The results of investigation indicate a positive effect of clenbuterol on carcass and breast muscle weight of ducks continuously administered the Beta-agonist. Treated animals showed a light colour of the meat and an higher protein content of breast muscle. The total collagen analysis showed a lower content in meat of duck of Group B; this result, however, does not mean a greater tenderness, because shear force values are unaffected by the substance. The detection of residues of Clenbuterol has been performed on serum, bile, liver, and breast muscle in experiment 1 and only in liver and breast muscle in experiment 2. The ELISA test has given different results depending on the substrate and the withdrawal period. Liver has been - as expected the preferential target for tghe accumulation, while in muscle the presence of the residue seems to be related to the length both of the treatment and of the withdrawal period

Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
