The Impact of Partial and Total Replacement of Soybean with Peanut Meal on Broilers Performance
Get PDFAn experiment was performed to show the Impact of replacing soybean meal with peanut meal on broiler growth performance. Three hundred lohman broiler males were obtained and reared for 42 days in an environmentally controlled poultry house. Birds were divided into three groups, each group assigned to 20 experimental units and allocated to 5 identical pens (20 birds / 1m2). Birds were offered ad libitum feed and water throughout the experimental period. Three different experimental diets were formulated as follows: T0; 0% peanut meal, T50; 50% soybean meal, and 50% peanut meal, and T100; 100% peanut meal. Birds body weight was measured every two weeks at the same time. Feed intake, average daily gain, and feed conversion ratio was calculated at the end of the experiment. The body weight was greater (p < 0.05) for birds that received peanut meal at 100% level (T100) more than birds consumed T0 and T50 diets at 14-28 days and at days 28-42. At day 28 - 42, feed intake was greater (p < 0.05) for broilers that had T100 diet than broilers which consumed T0 and T50. Average daily gain (ADG) and FCR was not affected (p > 0.05) by the different experimental diets. Therefore, feeding peanut meal had a positive effect on broiler growth performance and might be considered as an excellent protein source in broiler rations.

Effect of Hydroponic Barley Fodder on Awassi Lambs Performance
Get PDFThe objective of this research was to investigate the effect of feeding hydroponic barley (HB) on the performance of Awassi ram lambs. A total of 50 weaned lambs were used in a feeding trial by dividing it into two groups. The first was fed a total mixed ration diet (control) while lambs in the second group were fed similar ration except that barley grain was totally replaced by HB for 90 days feeding trial. Lambs were fed ad libitum twice per day and had a free access to fresh water. Feed offered and refusals were collected, body weight gain was measured weekly, and feed conversion ratio (FCR) was calculated. Results of the experiment showed that HB had a positive effect (p<0.05) on feed intake, final body weight, total gain, average daily gain, and FCR on lambs fed the HB diet when compared to lambs fed the control diet. In conclusion, HB can be used as feed for lambs in the fattening period to enhance their growth performance. Keywords: Awassi ram lambs, Hydroponic barley, Growth performance
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
