EFFECT OF DIFFERENT HOUSING ONPRODUCTIVE TRAITS AND ON SOMEBEHAVIOUR PATTERNS OF GROWINGRABBITS. PRELIMINARY RESULTS
No full textTwo-hundred-twenty-eight 5-week-old Pannon
White rabbits were housed in cages (2 rabbits/
cage, 0.12 m2) or in pens (13 rabbits/pen, 0.83
m2) with the same stocking density. Half of the
cages and pens had wire net floor while the other
half had plastic net. In every second cage and
pen wooden gnawing stick was fixed onto the
wall. Every second week a 24-hour video
recording was done. At 11 weeks of age ear
lesions were checked. Body weight of rabbits in cages was significantly higher between 7 and
11 weeks of age. Floor type had no influence on
weight gain and body weight. Rabbits in cages/
pens with gnawing stick were significantly
heavier at 11 weeks of age. Mortality was
independent of all treatments. Gnawing stick
consumption was significantly higher in pens.
Ear lesions were more frequent in rabbits housed
in pens or on plastic net, however, significant
difference was found only between rabbits with
or without wooden stick, with higher ear lesions
on rabbits reared without wooden stick
Response of fattening rabbits reared under different housing conditions. 2. Carcass and meat quality
No full textThis 2 x 2 x 2 factorial experiment was conducted to study the effects of housing system (pair caged - cage - : 2 rabbits/0.122 m(2) vs open top pen housed - pen - : 13 rabbits/0.86 m(2); same stocking density), floor type (wire mesh vs plastic net), and environmental enrichment (with vs without gnawing stick) on the meat quality of Pannon White growing rabbits (n = 64). The housing system significantly influenced slaughter weight (2590 vs 2531 g in cage or pen, respectively; P<0.01), reference carcass (RC) weight (1266 vs 1234 g; in cage or pen, respectively; P<0.05), and the hind leg meat to bone ratio (6.11 vs 5.62 in cage or pen, respectively, P<0.001). The animals reared in pens showed paler meat with lower pH(u) than that of those reared paired in cages. Hind leg meat dry matter and protein content were also influenced by the housing system (26.3 vs 25.9%, 21.9 vs 21.6%; in cage or pen. respectively; P<0.05). Pen housed rabbits had significantly heavier femur and tibia bone weight and higher fracture toughness than pair caged rabbits. Floor type affected the fore part/RC weight ratio (29.2 vs 29.6% of the RC on plastic net or wire mesh, respectively). Gnawing stick presence increased slaughter yield (59.0 vs 58.3%: P<0.05), RC weight (1266 vs 1236 g; P<0.05) and the forepart/RC ratio (29.6 vs 29.2% RC; P<0.05) while significantly reducing the meat colour b* value and increasing m. Longissimus dorsi shear force (0.60 vs 0.50 kg/cm(2): p<0.01). The hind leg meat fatty acid profile was only slightly influenced by experimental factors. Although this study showed pair caged rabbits to have increased carcass weight with better meatiness and other meat quality traits, hind leg bone strength was shown to be higher in pen housed rabbits
EFFECT OF FLOOR TYPE AND GNAWING STICKON THE CAGE-CHOICE OF THE GROWINGRABBITS
No full textFive-week-old Pannon White rabbits (n=112)
were weaned and housed into two blocks of
cages applying stocking density of 12 or 16
rabbits/m2. Both blocks were divided into four
cages of wire mesh (n=2) or plastic mesh floor
(n=2). In every second cage a gnawing stick was
fixed on the wall. The rabbits could freely move
among the four cages of the same block through
swing doors. A 24-hour infrared video recording
was taken once a week and the rabbits in each
cage were counted every half an hour.
Significantly more rabbits chose the cages of
plastic floor (16 rabbits/m2: 62.5%, 12 rabbits/
m2: 76.5%) than the cages of wire mesh floor.
With the increasing age between 5 and 11 weeks,
the ratio of rabbits on wire mesh floor increased.
This results show that the rabbits accept a less
preferable floor type instead of staying in higher
stocking density (kg/rabbits). The preference of
cages with gnawing sticks was also significant
(53.1-54.1%) but this effect was less pronounced
than that of the floor type

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Effetto di diversi sistemi di stabulazione sulle prestazioni produttive e sul comportamento dei conigli in accrescimento. Risultati preliminari
No full textDuecentoventotto conigli Pannon White di 5 settimane di età furono sistemati in gabbie di diverse dimensioni (0,12m2; 2 conigli/gabbia; oppure 0,83m2; 13 conigli/gabbia) ma con la medesima densità di allevamento (16 conigli/m2). Metà delle gabbie presentava un fondo in rete metallica, l’altra metà era dotata di un fondo in rete di plastica. Metà delle gabbie conteneva un arricchimento ambientale costituito da un bastoncino di legno. Dallo svezzamento alla macellazione (77 giorni di età) furono rilevate le prestazioni produttive. Alla macellazione, le orecchie dei conigli furono controllate per valutare la presenza e l’entità delle lesioni. Ogni 2 settimane furono effettuate delle videoregistrazioni allo scopo di monitorare l’uso del bastoncino di legno. Il peso vivo rilevato tra le 7 e le 11 settimane di età fu significativamente superiore nei conigli allevati in gabbie bicellulari. Il tipo di pavimentazione non influenzò le prestazioni produttive dei conigli. Gli animali che disponevano dell’arricchimento ambientale furono significativamente più pesanti alla macellazione. La mortalità osservata durante la prova fu indipendente dai fattori sperimentali. L’utilizzo del bastoncino di legno fu superiore negli animali allevati in gruppi di 12 (P<0,01). Le lesioni auricolari furono più frequenti nei conigli allevati in gruppo o in gabbie con fondo di plastica, ma le lesioni furono maggiormente rappresentate nei conigli sprovvisti di arricchimento ambientale (P<0,001)
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Response of fattening rabbits reared under different housing conditions. 1. Live performance and health status
No full textIn a 2 x 2 x 2 factorial experiment the effects of housing system (pair caged (cage): 2 rabbits/0.122 m(2) vs open top pen housed (pen): 13 rabbits/0.86 m(2): same stocking density), floor type (wire mesh vs plastic net) and environmental enrichment (with vs without gnawing stick) were studied on live performance, health status and welfare (ear lesions) of growing rabbits (n = 176). The housing system significantly influenced the body weight at 11 weeks of age (2630 vs 2557 g: in cage or pen, respectively) and the feed conversion (3.12 vs 3.38 g/g; in cage or pen, respectively). Floor type did not affect the traits tested. Gnawing stick consumption affected the body weight at 11 weeks of age (2553 vs 2622 g; without or with gnawing stick, respectively). the percentage of ear lesions (18.5 vs 1.20%; without or with gnawing stick, respectively). Some of the live performance traits of rabbits reared in pens was slightly lower. The presence of gnawing stick, especially in pens, reduced the aggressive behaviour and improved the welfare
