Risultati conseguiti con l’aggiunta di complessi aminoacidici a diete per suinetti
No full textLa ricerca è stata condotta su 144 suinetti svezzati a 24 giorni di età, mostrando risultati favorevoli nella fase di allevamento a terra / The addition of free amino acids to the diets was studied on 144 piglets 24 days old, from the weaning, showing favourable effects in the period of rearing on the ground
Effetti esercitati dall’autossidazione della quota lipidica in diete per broilers
No full textL'indagine, condotta su 300 pulcini Hubbard di entrambi i sessi, ha valutato gli effetti esercitati dall'autoossidazione della frazione lipidica dell'alimento sull'incremento ponderale, sull'indice di conversione e sulle rese di macellazione. Nessuno di tali parametri, nonchè l'esame delle carcasse e dei visceri dei soggetti macellati (1,7-2 kg di p.v.), ha evidenziato differenze significative
Ricerche sull’impiego di diete acidificate nello svezzamento precoce dei suinetti
No full textI risultati ottenuti con tre diversi acidi organici (citrico, fumarico e malico) nello svezzamento dei suinetti evidenziano che solo l'acido citrico, nei primi due mesi di vita degli animali, sembra dare risultati di qualche interesse pratico sulle performance di accrescimento, sulla digeribilità dei nutrienti e sulla microflora intestinale. Nelle fasi successive (fino a 4-5 mesi) i soggetti alimentati in precedenza con le diete acidificate assumono più alimento e mostrano una conseguente maggior rapidità di crescita
Aggiunta di aminoacidi ed oligopeptidi a diete per suinetti. Nota 1. Effetti sulle prestazioni produttive e sullo sviluppo della flora microbica intestinale
No full textLa ricerca è stata condotta su 36 suinetti maschi interi svezzati precocemente (21 giorni circa) / The effects of small quantities of aminoacid and oligopeptide pools added to balanced diets on growth and on intestinal microflora were studied on 36 male piglets weaned 21 days old
Le colibacillosi dei suini: cause alimentari e profilassi dietetica
No full textGli autori esaminano e discutono i rapporti intercorrenti tra nutrizione del suino e patologie intestinali, colibacillosi in primis, suggerendo indicazioni dietetiche per prevenirne e/o contenerne la comparsa e lo sviluppo
La nutrizione azotata del suino: ruolo biologico ed efficacia zootecnica di aminoacidi liberi e di oligopeptidi aggiunti alla dieta in piccole dosi
No full textLa ricerca è stata condotta su 36 suinetti maschi svezzati all'età di tre settimane e sacrificati dopo 35 giorni. I reperti sperimentali vengono in parte attribuiti ad un effetto extraproteico / The biological role and the zootechnical efficiency of free amino acids and oligopeptides added to the diet in small doses were studied on 36 male piglets weaned at three weeks of age and slaughtered after 35 days. The experimental results are in part ascribed to an extra-protein effect
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
