Sire-feed interactions for fattening performance and meat quality traits in growing-finishing pigs under a conventional and an organic feeding regimen
Get PDFIn a two-factorial feeding trial 120 growing-finishing pigs from eleven sires were fed on an organic (ORG) or a conventional (CON) diet. Diet ORG contained mainly oil press cakes and legume grains as protein source containing higher protein and crude fiber content along with slight deficiencies of limiting amino acids. Pigs were allocated to treatments balanced according to litter, sex and initial weight. Feed was offered ad libitum. Feed consumption, weight gain as well as carcass, meat and fat quality traits were recorded. ORG fed animals had lower weight gain, poorer feed conversion, lower loin muscle area, higher intramuscular fat content, higher ultimate pH (loin, ham), and a higher PUFA content in backfat. Despite for cook loss and dressing percentage, no sire-feed interactions were found. This indicates no need for a performance test, specifically designed for organic production. However, weight of the breeding values for the various traits and selection criteria should be adapted to the needs of organic production
Recommendations for Vitamin B2 supplements in organic slow-growing broilers
Get PDFIn this practice abstract, the four different controlled feeding trials using two riboflavin products at different concentrations showed that the newly available riboflavin product EcoVit R is equally suitable as the conventional one (Cuxavit); and that slow-growing broilers need less riboflavin than the currently recommended amounts for conventional broilers (Blum et al., 2015). Feed supplementation for organic slow-growing broilers is provided at 4.0 mg Vit B2/kg feed.

Wie gelingt der Ausstieg aus dem Kükentöten?
No full textDie jährliche Bio-Legehennentagung fand dieses Jahr Corona bedingt erstmalig als Hybrid-Veranstaltung statt. Erstmals standen neben den Legehennen auch die Hähne im Fokus. Am 26. Januar trafen sich 33 Teilnehmende im neuen Tagungsgebäude des FiBL in Frick, 73 weitere waren per Video hinzugeschaltet. Nach einigen allgemeinen Themen (siehe Artikel zum Bio-Eiermarkt auf S. 12) gab Adrian Schlageter als Einstieg ins Tagungsthema einen Überblick über die aktuellen Vorgaben von Bio Suisse zum Ausstieg aus dem Kükentöten. Für die Workshops am Nachmittag konnte auf einen grossen Erfahrungs- und Wissensschatz zurückgegriffen werden, denn rund die Hälfte der Teilnehmenden kam aus der Legehennenhaltung, und auch die Verarbeitung, Vermarktung und Junghennenaufzucht sowie einige Personen aus der Pouletmast und der Wissenschaft waren vertreten
Vitamin B2 supplementation for laying and parent hens in organic poultry systems
Get PDFThis practice abstract provides recommendations for organic poultry systems to meet the Vitamin B2 needs of the animals. Data from project experiments indicate that hens in or- ganic systems can be supplemented with a maximum level of 4.0 mg/kg feed without impacting the performance and animal health of the hens and their offspring. This level of supplementation is lower than the 5-7mg/kg feed recom- mended by Blum et al. (2015).
This practice abstract is recommended for organic poultry farmers across Europe

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
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
