Prah ružmarina kao dodatak prehrani prepelica: učinak na rast, svojstva trupa, sastav krvne plazme, crijevnu mikrofloru i imunost
Full text linkThis study was conducted to investigate the effects of feed supplementation with rosemary (Rosmarinus officinalis L.) powder (RP) on the performance, carcass traits, blood variables, antibody responses, and gut microbiota of quails. 270 one-day-old male Japanese quails were allotted to 6 dietary treatments with 3 replications (15 birds per pen). The diets contained RP at levels of 0 g/kg of feed (CON), 5 g/kg of feed (T05), 10 g/kg of feed (T10), 15 g/kg of feed (T15), 20 g/kg of feed (T20) or 25 g/kg of feed (T25). The trial lasted 42 days. Body weight and feed intake were measured weekly by pen, and the feed conversion ratio (FCR) was calculated. Blood samples were collected for assessing the humoral immune response to Newcastle vaccination at the 29th and 42nd days of age. Analysis of caecal microflora was performed on one quail per replication on the 14th and 42nd days of age. At slaughter, the carcasses and the organs were weighed, and blood constituent analyses were performed. Quails fed with RP had higher weight gain (PCilj rada bio je istražiti učinak dodatka praha ružmarina (Rosmarinus officinalis L.) u prehrani (RP) na rast, svojstva trupa, krvne pokazatelje, stvaranje protutijela i crijevnu mikrofloru prepelica. U ukupno 270 jednodnevnih japanskih prepelica primijenjeno je šest režima prehrane u tri ponavljanja (15 ptica po odjeljku). Hrana je sadržavala prah ružmarina u dozama od 0 g/kg hrane (CON), 5 g/kg hrane (T05), 10 g/kg hrane (T10), 15 g/kg hrane (T15), 20 g/kg hrane (T20) or 25 g/kg hrane (T25). Pokus je trajao 42 dana. Tjelesna masa i unos hrane mjereni su tjedno po odjeljku te je izračunata stopa konverzije hrane (FCR). Uzeti su uzorci krvi kako bi se procijenio humoralni imunosni odgovor na cjepivo protiv njukaslske bolesti 29. i 42. dan. Crijevna mikroflora analizirana je u jedne prepelice po ponavljanju 14. i 42. dan. Pri usmrćivanju izmjerena je masa organa i trupova te su analizirani krvni pokazatelji. Prepelice hranjene prahom ružmarina imale su veći prirast tjelesne mase (P 0,05) ni na crijevnu mikrofloru prepelica (P > 0,05). Prah ružmarina povećao je titar protutijela na cjepivo 29. dan (P < 0,05) i smanjio omjer LDL-a i HDL-a u plazmi (P < 0,05). Dodatak praha ružmarina do 25 g/kg po obroku poboljšao je svojstva i imunost prepelica a da nije negativno utjecao na njihovu crijevnu mikrofloru
Effects of feed supplementation with lavender (Lavandula angustifolia) essence on growth performance, carcass traits, blood constituents and caecal microbiota of broiler chickens
No full textThis study was conducted to investigate the effects of lavender (Lavandula angustifolia) essence on growth performance, carcass characteristics, blood parameters and caecal microflora of broiler chickens. Six experimental diets were formulated to include different levels of lavender essence as follows: 0 (control), 100, 200, 400, 600 and 800 mg/kg, respectively. A total of 300 1-day-old male broiler chicks (Ross-308 strain) were randomly allocated to the treatment groups (5 replicates with 10 birds each). Diets were fed as mash form in both starter (1–21 days) and grower-finisher (22–42 days) periods. From findings, no differences among treatments were observed for body weight (BW) gain, feed intake (FI), and feed conversion ratio (FCR) considering the entire feeding period (1–42 days). Birds given 400 mg/kg lavender had lower (P < 0.05) carcass, breast, thigh, wings, neck and gizzard weights than birds from the other groups. With the exception of the serum glucose level, which was significantly (P < 0.05) decreased in lavender fed groups, there were no differences (P > 0.05) in serum levels of total protein, cholesterol, triglycerides, high-density lipoprotein (HDL), low-density lipoprotein (LDL) and uric acid among treatments. Broilers fed 600 mg/kg lavender essence had lower (P < 0.05) counts of caecal Lactobacillus spp. than others groups. E. coli and Coliforms counts were decreased (P < 0.05) in birds fed 600 mg/kg lavender. Therefore, based on the current study, it can be concluded that lavender essence can successfully be used as antibacterial agent in broiler diets without any detrimental effect on growth performance
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
