PERFORMANCE OF BROILERS FED VARYING LEVELS OF BIOTIN AND PALM KERNEL OIL

A total of four hundred and eighty day-old commercial b+oiler chicks were assigned t? 12 dietary treatments in a 2 x 6 factorial experiment to study the effects of biotin and palm kernel oil supplementation on their performance and carcass characteristics. Measurements of average daily weight gain, average daily feed intake, carcass weight,' dressing percentage, total edible meat weight and total bone weight showed that a minimum of 120 mcg biotin per kg of feed was needed by broiler chicks for optimum perfor~ance. All carcass characteristics examined except total bone expressed as percentage of carcass weight were positively correlated with di.et~ry biotin level, although none was significant , (P>0.'05). Supplementation of diet with 2% palm kernel oil significan.tly (P<0.05) reduced average daily feed intake and ' average weight gain but did not affect feed efficiency (gairi/feedintake) and carcaSB characteristics of broiler

Preliminary Investigation on the Effect of Dietary Supplement Biotin and Palm Kernel Oil on Blood,Liver and Kidney Lipids in Chicks

A total of 480 day-old broiler chicks were used in two trials conducted to investigate the performance and lipid contents of blood, liver and kidneys of birds when fed varying levels of palm kernel oil (0% and 2%) and biotin (40, 80, 120, 160, 200 and 240 I1lcg/kg feed) in a 2 x 6 factOlial experimental design. The results showed that blood, liver and kidney lipid concentrations were significantly affected by dietary biotin treatments. While total lipid, free fatty acid, triglyceride and cholesterol contents were negatively correlated with dietary biotin level, phospholipid concentrations were positively correlated. Biotin-deficient chicks had significantly higher total lipid, free fatty acid, triglyceride and cholesterol but lower phospholipid contents in their blood and the two organs. Supplementation of the diet with 2% palm kernel oil significantly elevated blood phospholipid concentration, but depressed the accumulation of the other lipid fractions in both organs and the blood of birds. Blood, liver and kidney cholesterol concentrations were not affected by 2% fat supplementation. Observation on the lipid parameters coupled with the results on feed utilisation appeared to suggest that a minimum of 120 mcg of the vitamin per kilograme of diet was required by broiler chicks for optimum performance

Knowledge sharing behaviour by librarians in federal universities in Nigeria

The ongoing debate in the international community’s is on the evaluation of knowledge sharing and its impact on organisational effectiveness. Librarians play a pivotal role in helping the university to realise the objective of teaching, learning and research. Librarians provide access to information resources and services to support the vision and mission of their parent institution. Knowledge are being created daily in organisation, hence, they should be shared. Although, there have been researches on knowledge sharing by librarians in Nigeria but the focus have always been on sectional part or on one or two geo-political zones, without national study as scope of study. This study therefore investigated knowledge sharing by librarians in federal universities in Nigeria. The population of study comprised 654 librarians from 40 federal universities in Nigeria. A total enumeration technique was used to cover 654 librarians. The descriptive statistics was employed for data analysis. 518 respondents filled and returned the questionnaire, given a response rate of 79.2%. The results revealed that the level of knowledge sharing by librarians is high ( =98.47. SD =11.54). The channel of knowledge sharing by librarians varies significantly from face-to-face to the use of social media. Significant difference exists on knowledge sharing by librarians based on the universities. The study concludes that librarians are not only knowledge managers but also knowledge disseminators. Therefore, library administrators should establish as well as formalised knowledge sharing hours in the library so that the culture of knowledge sharing can be maintained among the librarians. Recognition and incentives be given to librarians who share knowledge so that they can share more knowledge

Library Use Education as a Correlate of Use of Library Resources in a Nigerian University

The study focused on the effective of library education as a correlate to the use of library resources in a Nigerian university. The hallmark of education is the ability of the recipient of it to put whatever they have learnt into practice. Students in Nigerian tertiary institutions are introduced to the use of library to quicken their efforts in getting and using the library resources at the quickest possible time. The study also attempts to know the extent of the use of library resources and services. The relevance of library use education to the under study population are also investigated. The results of the findings revealed that much has not been achieved on the use of library resources and services and the use of Information Technology (IT) tools in the library. Urgent improvements are necessary in the areas investigated in order that the aim and objective of the library use education could be fully achieved, as suggestions for its improvements are also given

Comparative efficacy of three commercial vitamin and trace mineral premixes for rearing broiler chickens at starter and finisher phases

Six groups of 45 unsexed day-old Hubbard broiler chicks were randomly assigned in duplicate at the starter phase (0-5 weeks) to three isocaloric and iso-nitrogenous diets which were fortified at manufacturers recommended levels with three commercial vitamin and trace mineral premixes purchased locally and labelled as premix A, U and Z. At the finisher phase (6 -9 weeks) the birds were shuffled and subdivided into three finisher treatment groups of two replicates each. One treatment group continued to receive the same premix as during the starter phase, while the other two groups were assigned the remaining premixes not given at the starter phase for that particular treatment group. Thus nine premix combinations were used at the finisher phase. The premix type fed at the starter phase led to differences (P > 0.05) in the protein intake, mean weight gain and weight gain per unit protein intake of the birds. Protein intake and weight gain per unit protein intake were not significantly different (P < 0.05) at the finisher phase. The serum uric and serum creatinine levels indicate that birds fed premix Z at the starter phase utilized the dietary protein more efficiently than those fed the other two premixes. Variable values were obtained for the serum metabolites at the finisher phase. It was concluded that available premixes for broilers in Nigeria vary in their content and their effect of protein nutriture ofbroiler chickens. It is recommended that if combinations of premixes are to be used in rearing broilers, care should be taken to feed a proven premix of good quality at the starter phase

The stifdv population 1 comprised II 0 library professional and paraprofessional personnel working in the cataloguing section oft he {en jetJeral and state university libraries in South-West Nigeria. Total enumeration technique was used to randomly se,fect the study population for this study. Data for this study was collected using questionnaire. A 5-point Likert scale were' used with 1-5 representing 'strongly agree', 'agree', 'undecided', . 'disagree' and 'strongly disagree ' respectively, ·to e/idit information .from the respondents. A total of II 0 copies of the questionnaires were distributed to the respondents. 85 copies of the questionnaires were retrieved and valid for analysis. Data were analysed using charts, table, frequencies, percentage, mean and standard deviation. The result of the study find out that automation is. changing positively the way bibliographic details are being created and displayed. Cataloguing is now quicker with the automated system and that automated system is preferred to the manoa/ system. The study highlighted various benefits of cataloguing automation such as automation · improve inter-personal relationship, saves time, easy feedback/rom library user, etc.The study recommends that libraries should not be satisfied with the little benefits derived from the partial automation of the cataloguing and other sections of the libraries but should fully automate the systems and continuously upgrade the automated systems especially as technology unfol

Fish sorting assessments of Clarias gariepinus fingerlings raised in fish tanks

Fish sorting assessments of Clarias gariepinus fingerlings stocked and raised in fish tanks were undertaken for a 6-month culture period: Sorting was undertaken from the first, second, and third months of stocking the fish fingerlings while the control was not sorted at all. The sorting assessments revealed that the twice sorting of fish fingerlings stocked with a Marginal Rate of Return (MRR) of 3.44 was significantly different (p>0.05) from those sorted once with MRR of 0.912, and three times with MRR of 2.65 respectively, thus making twice sorting most advisable for fish farmers utilizing Clarias gariepinus fingerlings for tank aquacultur

Information Needs, Information Sources and Information Seeking Behaviour of Agricultural Extension Workers in Osogbo Zone of Osun State, Nigeria

The study investigated information needs, information sources, and information seeking behaviour of agricultural extension workers in Osogbo zone of Osun State, Nigeria. It also focused on the factors influencing the choice of information sources and problems encountered when sourcing for information. A structured questionnaire was used to collect data from 54 respondents in the study area out of which 50 (98.6%) responded and were used for the analysis. Descriptive statistics were used to analyze the data using percentage and tables. Findings showed that personal collections, colleagues, radio and television programmes were the most used sources of information by extension workers in the study area. Furthermore, the ability of information sources to meet the information needs and reliability of the information sources were the major factor influencing the choice of information sources. The study discovered that non-availability of relevant information and inadequate current information sources were seen as main problems confronting the extension workers. Thus, accessibility of agricultural database, the establishment of agricultural information centres, making information sources attractive, and that extension workers should liaise with agricultural research centres for acquiring more knowledge were the suggestions made for improving the information needs, sources and seeking behaviour of extension workers in the course of this study
