Effects of extruded linseed dietary supplementation on milk yield, milk quality and lipid metabolism of dairy cows
Get PDFTwenty Italian Friesian dairy cows were used in an experimental trial to study the effects ofextruded linseed dietary supplementation on milk production, milk quality and fatty acid (FA) percentages of milkfat and total plasma lipids and plasma phospholipids. Control cows were fed a corn silage based total mixed ration(TMR) while treated animals also received 700g/head/d of extruded linseed supplementation. Feed intake was similarbetween groups. Milk yields was tendentially greater for cows fed extruded linseed. Milk urea content (P<0.05)were reduced by treatment. Results showed a significant increase n-3 FA concentration (particularly alpha linolenicacid) and a significant reduction of n-6/n-3 FA ratio in milk fat, total plasma lipids and plasma phospholipids(P<0.001); moreover a reduction trend (P<0.1) of arachidonic acid concentrations was observed in milk fat, totalplasma lipids and plasma phospholipids. At last, treatment enhanced milk fat conjugated linoleic acid (CLA) percentage(P<0.05).[...
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
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
Effetto delle condizioni ambientali e dei sistemi irrigui sulle caratteristiche qualitative del silomais
No full textEsistono diversi fattori agronomici in grado di influenzare la qualità del mais soprattutto in termini di contenuto in amido e digeribilità della NDF. Fra questi la gestione dell’irrigazione sembra avere un ruolo importante. Van Soest (1994) ha dimostrato che un eccesso di acqua in presenza di temperature ambientali molto elevate conduce ad un aumento della deposizione di lignina da parte della pianta con diminuzione sostanziale della digeribilità della NDF. Con il presente lavoro si è appurato come diverse tipologie d’irrigazione influenzino la qualità dell’insilato di mais in termini di degradabilità della fibra e di deposizione di amido
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
Effects of a soybean-free diet supplied to Italian heavy pigs on fattening performance, and meat and dry-cured ham quality
Get PDFThe aim of this study was to investigate the effects of a diet containing non-conventional (i.e. alternative to soy ean meal) vegetable protein sources on fattening performance, and meat and dry-cured ham quality of heavy pigs. Fifty-six (Landrace x Large White) castrated males with an initial average body weight of 50 kg were allocated to two experimental groups: a control group in which pigs received a traditional soybean meal-based diet, and a treatment group in which soybean meal was replaced by vegetable protein sources (i.e. sunflower meal, potato protein, corn gluten feed, faba beans and dehydrated alfalfa meal), mainly locally grown and not genetically modified. Pigs were slaughtered at approximately 160 kg body weight. Dietary treatment had no significant effect on fattening performance, or meat, fat or dry-cured ham properties. Results suggest
that it is possible to feed heavy pigs a soybean-free diet without impairing fattening performance or the quality of meat and Italian PDO (Protected Designation of Origin) hams
