The Effect of Adhatoda Vasica as A Herbal Supplement on The Performance, Nutrient Digestibility, and Blood Profile of Weaned Pigs
No full textA 60-day trial was carried out to determine the impact of Adhatoda vasica as an herbal supplement on the performance, nutrient digestibility and blood profile of weaned pigs. 40 crossbred male pigs (Yorkshire × Landrace) with initial body weight of 10.21 ± 0.03 kg was distributed into 4 treatment consisting of 10 pigs each. On arrival, animals were quarantined for two weeks and fed basal diet which is adequate in all nutrients according to NRC (2012). Pigs in treatment 1 was fed basal diet without Adhatoda vasica leaf powder while those in treatment 2, 3 and 4 were fed same diet supplemented with Adhatoda vasica leaf powder at 200 g, 400 g and 600 g/kg respectively. A completely randomized design technique was adopted and the animals had unrestricted access to clean fresh water and feed. Quantification of phyto-constituents in Adhatoda vasica leaf powder showed that it contained higher concentration of flavonoids (102.1 mg/g) while steroids had the lowest concentration of 30.41 mg/g. Average daily weight gain was higher among pigs fed treatment 3 and 4, intermediate in treatment 2 and lowest in treatment 1. Average daily feed intake, feed conversion ratio and mortality were significantly (P<0.05) influenced by the treatment. Dry matter, ether extract, crude protein and crude fibre digestibility were influenced (P<0.05) by the treatment. Red blood cell, pack cell volume, mean platelet volume, mean corpuscular volume, mean corpuscular haemoglobin, white blood cell, total protein was significantly (P<0.05) different among the treatment except for aspartate amino transferase, alanine amino transferase and alkaline phosphatase (P>0.05). However, all values were within the established range for healthy pigs. In conclusion, Adhatoda vasica leaf powder can be supplemented in the diet of pigs without compromising their growth and health status
Cordyline fruticosa leaf powder supplemented in the diet of weaned pigs: effect on growth performance, heamatological and serum biochemical indices
No full textIn Sumitra Research Institute, Gujarat, a total of 50 cross-bred male piglets (Yorkshire × Landrace) with an initial body weight of 9.77 ± 0.06 kg weaned at 28 days were randomly distributed 5 treatments of 10 replicates containing 1 animal each in 60 days’ trial. According to the Nutritional Research Council’s recommendation in 2012, a basal diet was adequate in all nutrients. Pigs in treatment 1 were fed a basal diet without C. fruticosa leaf powder while treatments 2, 3, 4, and 5 were fed the same diet supplemented with C. fruticosa leaf powder at 20 g, 40 g, 60 g, and 80 g respectively. Animals were given unrestricted access to fresh clean water and a completely randomized design was adopted. The experimental result showed that average daily weight gains and average daily feed intake which took the form of 0.29-0.46 kg and 0.68-0.77 kg were higher in the C. fruticosa leaf powder-supplemented group relative to the control (p < 0.05). The treatments significantly influenced the best feed conversion ratio and mortality rate from 1.73-2.34 to 1.0-3.0% (p < 0.05). Haemoglobin, red blood cell, pack cell volume, total platelet count, mean platelet volume, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, white blood cell, lymphocytes, and monocytes count follow a similar trend as values were greater in treatment 3, 4 and 5, an intermediary in treatment 2 and lower in treatment 1 (p < 0.05). The treatment significantly influenced total protein, glucose, cholesterol, Calcium, and Phosphorus values (p < 0.05). In contrast, bilirubin, urea, creatinine, sodium, chloride, alanine transaminase, aspartate aminotransferase, and alkaline phosphatase values were similar among the treatments (p > 0.05). In conclusion, Cordyline fruticosa leaf powder can be supplemented in the diet of weaned pigs without causing any negative effect on the growth and health status of weaned pigs
Prosopis Africana Extracts as Potential Natural Alternatives to Synthetic Antibiotics and a Key for Sustainable Broiler Production: a Review
No full textThe chicken sector is more vulnerable to antimicrobial resistance, the buildup of toxic or dangerous residues in meat and eggs, and environmental contamination as a result of the widespread and careless use of antibiotics in most nations. Natural solutions, such as medicinal plants, are required to address these issues. These plants have been shown to contain a variety of phytochemicals, including phenols, flavonoids, terpenoids, tannins, alkaloids, and saponins. These chemicals endow plants with a multitude of medicinal qualities. One of the many alternatives to antibiotics is Prosopis africana extract, which includes stem bark, leaves, roots, and their essential oils. Antioxidant, antibacterial, antifungal, anti-helminthic, antiviral, hepatoprotective, immune-stimulatory, and antimicrobial properties are among the many pharmacological activity of P. africana preparations. They are also an abundant supplier of vital minerals and amino acids that support enzyme function and provide defense against the effects of oxidative stress. Using extracts from Prosopis africana is the way forward for effective chicken production, environmental sustainability and food hygiene
Dracaena Mannii Leaf Meal Supplementation in Broiler Chicks: Effects on Growth Performance, Haematology and Serum Biochemical Indices
No full textThe study aimed to investigate the impact of Dracaena mannii leaf meal on the growth performance and haematological and biochemical indices of Hubbard broiler chicks. 200 chicks were divided into four groups, each with a different diet. The diets were based on corn-soya meal without Dracaena mannii leaf (DMF), with DMF added at different amounts. The study found that DMF contained flavonoids, phenols, tannins, alkaloids, steroids, and saponins. The average daily feed intake was similar in diets 3 and 4, but significantly higher than in diets 1 and 2, with no mortality recorded. The diets significantly influenced pack cell volume, red blood cell, haemoglobin, white blood cell, leucocytes, and monocyte counts, but within the optimal range for healthy birds. The study concluded that DMF supplementation up to 600 g can optimize broiler performance without negatively impacting their health status.The study aimed to investigate the impact of Dracaena mannii leaf meal on the growth performance and haematological and biochemical indices of Hubbard broiler chicks. 200 chicks were divided into four groups, each with a different diet.

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
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
