Influence of genotype on meat quality in kids
No full textThe research meant to evaluate carcase characteristics and meat quality traits of kids from three genotypes bred in Southern Italy. The trial was carried out in a farm located in Basilicata on 15 male kids born as singletons of three genotypes: Garganica (G), Maltese (M) and Siriana (S) that were fed only milk, suckling from their dams until they were about 21! days old. Afterwards, the kids were weaned with a pelleted feed administered ad libitum and slaughtered at 60! days of age. Dams grazed for about ten hours during the day and received hay ad libitum and a commercial feed (500 g/head/day) at housing, in the evening. Genotype did not affect growth performances. As for slaughtering data, a significantly lower net cold dressing percentage was recorded for M kids (56.42%; SEM =3.723) in comparison with G (64.22%; p<.01) and S (62.51%, p<.05). In M kids the dissection of the right half carcase into meat cuts showed a significantly (p<.05) lower incidence of the loin (5.78% vs. 6.86 and 7.06%, respectively for S and G breeds; SEM =0.711) and leg (30.15%; SEM =0.388) as compared to S (29.69%; p<.01) and G (32.21%; p<.05). Separation of the leg and the loin into their tissue components did not show any significant difference between genotypes as for the proportion of lean, fat and bone. No significant differences aroused between breeds for pH and meat colour features of the Longissimus dorsi (Ld) and Semimembranosus (Sm) muscles. Shear force (WBS) of the Ld muscle of G kids was significantly lower (p<.05) compared to M and S breeds (5.15 vs. 7.95 and 7.27 kg/cm2, respectively; SEM =1.553) while no effect of breed was recorded on tenderness of the Sm muscle. The total collagen content assessed on the Ld muscle showed no significant difference between genotypes. Meat lipid oxidation, measured by 2-thiobarbituric acid reactive substances (TBARS), showed that Ld meat stored for 10!days at 4 °C had a significantly (p<.01) higher value of malondialdehyde content (mg MDA/kg meat) in the G breed compared to S and M (0.77 vs. 0.28 and 0.38, respectively; SEM =0.206)
Dietary supplementation with oregano and linseed in garganica suckling kids: Effects on growth performances and meat quality
Full text linkMeat from Garganica kids fed diets containing oregano and linseed was analysed for physical and sensory properties, chemical and fatty acid composition of intramuscular lipids. Twenty-one three-week-old kids were divided into three homogeneous groups (n = 7), according to age and body weight, and assigned to one of the following feeding treatments: C) control: commercial pelleted feed; L) pelleted feed containing 3% extruded linseed; LO) pelleted feed containing 3% extruded linseed and 0.6% dried oregano inflorescences. Kids were slaughtered at 60 days of age. Diet did not affect in vivo performances, dressing percentage, pH and meat colour, but it influenced meat tenderness, that was lower (P<0.01) in meat from kids receiving oregano, probably due to the lesser (P<0.05) fat content of their meat. The use of oregano also resulted in a lower muscle fat oxidation and in a better meat flavour. As for human health, the dietary supplementation with linseed improved the muscle fatty acid composition, resulting in higher levels of α-linolenic acid (P<0.05) and in a lower n-6/n-3 ratio
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
Variations on the Author
Full text link“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
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
