Can liquorice extract administered as dietary and/or as food supplement improve rabbit meat shelf-life?
No full textEffect of diet and packaging system on the oxidative status and polyunsaturated fatty acid content of rabbit meat during retail display
No full textThe aim of this study was to evaluate the combined effect of two dietary lipid sources (sunflower vs. linseed oil)
and three packaging methods (PVC film – BAG vs. modified atmosphere CO2 20%+80% O2 – MAP vs. and
vacuum - VAC) on the oxidative status and polyunsaturated fatty acid content of rabbit loins (Longissimus thoracis
et lumborum muscle), at days 1, 4 and 10 of simulated retail display. The diet, storage time and packaging
method affected the oxidative status of rabbit meat under retail display. As expected, storage time, independently
on the other factors, significantly reduced the antioxidant content of loin meat. Accordingly, TBARs
values significantly increased during storage, as well as the dietary supplementation of linseed. The fatty acid
profile of the fresh loin closely respected that of the diets. At day 10, oxidative status and fatty acid profile of
MAP samples could be yet considered optimal

No full textMain facts in rabbit nutrition and feeding: past and recent perspectives
No full textAvailable knowledge in rabbit nutrition and feeding guarantees the optimization of productive and reproductive performance of the genetic types used in rabbit commercial farms because nutritional requirements have been largely investigated and are known. Nevertheless, performance alone are not sufficient to maximize global farm feed efficiency, which can be achieved only when animals are in health, i.e. in absence or with minimum losses due to morbidity and mortality. Thus, research has assessed for a long time the effect of the changes in the levels of main dietary constituents (firstly fibre, starch and protein) on performance and health. Now, attention is more and more towards the effects of the different fractions in main nutrients, in particular soluble and insoluble fibre. Relationships and possible synergistic effects among different nutrients and feeding techniques (e.g. feed restriction) are evaluated with a multisciplinary approach, which addresses effects on immune response and gut microbiota as key factors in regulating rabbit health. Current feeding techniques also pay attention to the effects of the dietary changes on environment, in terms of nitrogen excretion
Effect of Carduus marianum herb on the productive performances of growing rabbits
No full textThe European ban of AGPs in the animal feed from 2006 had 151
revived doubts previously considered dismissed, such as those regarding the control of the farm animal productive performances and health status protection. Carduus marianum is an herbaceous plant from the Mediterranean countries traditionally used in liver and gastrointestinal diseases as natural remedy. In the present study was shown the efficacy of Carduus marianum podwer feed addictive in the growing rabbit performances. 144 animals were divided in three groups: the control group (C=51 animals) was fed
with a basal diet, the other two groups received the basal diet with supplementation of Carduus
marianum herbal power in two concentrations: 0.5% (H1, n=48) or 1.0% (H2, n=45). The rabbits
were reared from 5th to 11th weeks and, subsequently, were slaughtered, then carcasses were
weighed, chilled for 24 h at 3 °C, dissected and carcass yield were calculated. Fore, mid and hind
parts were dissected and the percentage on the chilled carcass was calculated. The results showed
how growth performances and carcass traits were not affected by supplementation of Carduus
marianum herbal extract, with exception of H2 mortality values that were lower (P<0.05)
particularly during the week 7-8
Effect of diet and packaging system on the microbial status, pH, color and sensory traits of rabbit meat evaluated during chilled storage
No full textThe combined effect of two dietary lipid sources (sunflower vs linseed oil) and three packaging methods (PVC
film - BAG, modified atmosphere CO2 20%+80% O2 - MAP, and vacuum - VAC) on the shelf-life (pH, color,
microbial count, sensory traits) of rabbit loins was tested at days 1, 4 and 10 of refrigerated storage. Linseed oil
did not adversely affect neither the physical or sensory traits, nor the microbiological quality of rabbit meat
throughout the shelf-life trial. The three packaging methods were all similarly effective in maintaining the
physical and sensory quality of the meat, irrespective of the different dietary lipid sources and thus different
susceptibility to oxidation. MAP and VAC were more effective than BAG in preserving rabbit meat hygienic
quality, as highlighted by the microbial count analyzed at day 4 of shelf-life (P < 0.001). At day 10, the microbiological
quality didn't differ between MAP and VAC rabbit meat samples
Going Beyond Counting First Authors in Author Co-citation Analysis
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
