Feed intake, live weight gain and reproductive performance of Menz ewes supplemented with Lablab purpureus, graded levels of Leucaena pallida 14203 and Sesbania sesban 1198
No full textThe research was conducted at the International Livestock Research Institute's Debre Zeit Research Station in Ethiopia. Leucaena pallida 14203, Sesbania sesban 1198 and Lablab purpureus were grown, harvested and dried at the research station. Seventy individually penned Menz ewes with a mean initial weight of 18.6+/-0.41 kg (mean+/-S.D.) were used in a randomized block design experiment that lasted for 6 months. Treatments consisted of supplementing ewes with L. pallida 14203 or S. sesban 1198 at 0.9%, 1.2% or 1.5% of live weight (LW). L. purpureus, offered at 1.2% of LW was used as a positive control. The basal feed tef straw (Eragrostis tef) was offered at 20% of refusal. Data on feed intake, LW gain, reproductive parameters and plasma activities of aspartate aminotransferase (AST), creatine kinase (CK), [gamma]-glutamyletransferase ([gamma]-GT) and alanine aminotransferase (ALT) were collected and analyzed. Graded levels of L. pallida 14203 promoted superior intakes of basal feed dry matter (DM) (PPPS. sesban 1198. Intake of basal feed DM was higher (PL. pallida 14203. Supplementation with S. sesban 1198 than with the same level of either L. pallida 14203 or L. purpureus resulted in increased (PL. pallida 14203 were heavier (PPL. purpureus or S. sesban 1198. Ewe weight at lambing was positively correlated (PPS. sesban 1198 appears to interfere with the reproduction of ewes and thus it could be considered as unsuitable supplement feed to pregnant ewes for an extended period of feeding. The plasma activities of assayed enzymes suggest that S. sesban 1198 may contain hepato-toxic anti-nutritive factors
Effects of supplementation with L. purpureus, graded levels of L. pallida 14203 or S. sesban 1198 on feed intake and live weight gain of Menz sheep
No full textThe research was conducted at the International Livestock Research Institute's (ILRI) Debre Zeit research station situated in the central highlands of Ethiopia at 38° 58' E. 80 44' N. The multipurpose tree (MPTs) leaves and L. purpureus were harvested and dried in a shade at the research station. Seventy individually penned Menz ewes with a mean initial weight of 14.77 f 0.32 kg (mean t SD) were supplemented with L. pallida 14203, S. sesban 1198 at 0.9 °%, 1.2 % and 1. 5 % of live weight for a feeding period of 5 months. L. purpureus, supplemented at 1.2 % of live weight was used as a control. The basal feed, chopped tef straw, mineral blocks and water were offered ad libitum. The experimental design was a randomized block design. Sheep were weighed fortnightly. Content of crude protein (CP) was lower and that of fiber was higher in L. purpureus compared to both MPTs. Soluble phenolics and condensed tannins were highest in L. pallida 14203, followed by S. sesban 1198 and least in L. purpureus. At equal levels of offer, DCP intake was significantly lower (P < 0.001) in sheep supplemented with L. pallida 14203 than those supplemented with S. sesban 1198 or L. purpureus. L. pallida 14203 was readily consumed, whereas animals on L. purpureus and higher levels of S. sesban 1198 did not totally consume offered supplement feed. Daily live weight gain was significantly higher in S. sesban 1198 supplemented than in L. pallida 14203 (P < 0.05) or L. purpureus (P < 0.01) supplemented animals
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
Supplementation of Menz ewes with dried leaves of Lablab purpureus or graded levels of Leucaena pallida 14203 and Sesbania sesban 1198: Effects on feed intake, live weight gain and estrous cycle
No full textThe research was conducted at the International Livestock Research Institute, Debre Zeit Research Station, which is situated in the central highlands of Ethiopia. Leaves of Lablab purpureus and the multipurpose trees (MPT), namely, Leucaena pallida 14203 and Sesbania sesban 1198 were harvested and dried in a shade at the research station. Seventy individually penned Menz ewes with a mean initial weight of 14.77+/-0.32kg (mean+/-S.D.) were randomly assigned to seven treatments in a randomized block design. The ewes were supplemented daily with three levels of L. pallida 14203, namely, LP1 (8.3gDMkg-1LW), LP2 (11gDMkg-1LW), LP3 (13.3gDMkg-1LW); three levels of S. sesban 1198, namely, SS1 (8.2gDMkg-1LW), SS2 (10.9gDMkg-1LW), SS3 (13.3gDMkg-1LW) and one level of L. purpureus, LAB (10.5gDMkg-1LW), which was used as a control. The basal feed, chopped tef (Eragrostis tef) straw, mineral blocks and water were offered ad libitum. The feeding period lasted for 5 months. Body weight was measured fortnightly, and monitoring of estrus was conducted twice daily for 60 days by visual observation and using vasectomized rams.Contents of crude protein (CP) were lower, and that of neutral detergent fiber (NDF), acid detergent fiber (ADF) and acid detergent lignin (ADL) were higher in L. purpureus compared to both MPTs. Soluble phenolics and condensed tannins were highest in L. pallida 14203, followed by S. sesban 1198 and least in L. purpureus. At equal levels of offer, digestible crude protein (DCP) intake was lower (PL. pallida 14203 than with S. sesban 1198 or L. purpureus. L. pallida 14203 was readily consumed, whereas animals on L. purpureus and higher levels of S. sesban 1198 had variable quantities of refusals. Supplementation with L. pallida 14203 compared to S. sesban 1198 resulted in higher proportions (PPS. sesban 1198 than the two lower levels in the first and in the overall mean of the three estrous cycles monitored. Daily live weight gain was higher when the animals were supplemented with S. sesban 1198 as opposed to L. pallida 14203 (PL. purpureus (PL. pallida 14203 at all levels of supplementation maintained in this study, whereas some anti-nutritional factors in S. sesban 1198 may limit its intake at higher levels of offer. Moreover, supplementation with S. sesban 1198 had a negative influence on the reproduction of ewes by compromising manifestation of estrus when offered at the highest level of supplementation
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
