The data consisted of 369 lactation records for calvings over a sixteen-year period (1972-1987) and included only cows that had normal milk records. The data were analysed using a linear model containing the fixed effects of parity, year of calving and season of calving. The least squares means${\pm}$S.E. were $1,273{\pm}58.4kg$ for milk yield, and for post-partum body weight (kg) at 2, 3 and 4 months after calving were $343.40{\pm}3.96$, $346.10{\pm}4.10$ and $352.54{\pm}4.26$, respectively. With the exception of season of calving, the effects of parity and year of calving were significant (p<0.01) on the performance of the animals. Thus, the mean-milk yields 1162, 1351 and 1350, were similar for pre-, peak- and post rainy seasons, respectively. On the other hand, as parity increased from 1 to 3, milk yield also increased, but thereafter, there was a gradual decline in milk yield. Similarly, post-partum body weight also increased with parity. However, no consistent pattern for year effect was observed which probably was a reflection of the variation in climatic conditions, or forage quality and/or availability. The phenotypic correlations between milk yield and post-partum body weights were negative and small (ranging from -0.01 to -0.08). However, high milk production in cows was associated with longer calving interval. The implications from the phenotypic correlations are suggestive of one or two possibilities. Firstly, selection for increased body weight may actually result in decreased milk yield. Also, a substantial genetic antagonism may exist between milk yield and fertility in the crossbred cows. Therefore, it is important that selection to improve milk production should take into consideration the reproductive performance of the cows.

A.A. Oni,D.O. Ogbolu,O.A. Daini,A.P. Oloko 한국식품영양과학회 2007 Journal of medicinal food Vol.10 No.2

The emergence of antimicrobial resistance, coupled with the availability of fewer antifungal agents with fungi-cidal actions, prompted this present study to characterize Candida species in our environment and determine the effectivenessof virgin coconut oil as an antifungal agent on these species. In 2004, 52 recent isolates of Candida species were obtainedfrom clinical specimens sent to the Medical Microbiology Laboratory, University College Hospital, Ibadan, Nigeria. Theirsusceptibilities to virgin coconut oil and fluconazole were studied by using the agar-well diffusion technique. Candida albi-canswas the most common isolate from clinical specimens (17); others were Candida glabrata(nine), Candida tropicalis(seven), Candida parapsilosis(seven), Candida stellatoidea(six), and Candida krusei(six). C. albicanshad the highest sus-ceptibility to coconut oil (100%), with a minimum inhibitory concentration (MIC) of 25% (1:4 dilution), while fluconazolehad 100% susceptibility at an MIC of 64 .g/mL (1:2 dilution). C. kruseishowed the highest resistance to coconut oil withan MIC of 100% (undiluted), while fluconazole had an MIC of . 128 .g/mL. It is noteworthy that coconut oil was activeagainst species of Candida at 100% concentration compared to fluconazole. Coconut oil should be used in the treatment offungal infections in view of emerging drug-resistant Candida species.

This study investigated the relationship between class size and students’ participation on the academic performance of senior secondary school students in Nigeria. The population for this study comprised all the Senior Secondary school students in Mainland Local Government Area, Lagos State. The study adopted descriptive survey design and random sampling technique was used in arriving at the selection of two hundred and seventy (270) students and thirty (30) teachers among the population of senior secondary school students in Mainland Local Government Area in Lagos State, which formed the sample of this study. Specifically, students and teachers were randomly selected from six Senior Secondary schools in Mainland Local Government in Lagos State. Forty five (45) Senior Secondary school students and five (5) teachers were randomly sampled from each school. Two self- developed, structured and validated questionnaires (students’ questionnaire and teachers’ questionnaire) of 15 items for teachers’ questionnaire and 18 items for students’ questionnaire were used to collect information from the students and teachers after its validity and reliability were determined. The data collected were analyzed using mean, standard deviation, simple percentage while Pearson Product Moment Correlation Coefficient statistical tool was used for hypothesis testing at 0.05 levels of significance. The study revealed that: there is no significant relationship between class size and academic performance. There is significant difference between the students’ participation and their academics performance in secondary schools. There is no significance relationship between students’ perception of class size and the academic performance. There is no significance relationship between teachers’ perception of class size and the students’ academic performance.

This study investigated principals’ involvement of students in decision-making and private secondary school effectiveness in Lagos State Nigeria. Four hypotheses were tested. An ex post facto research design was adopted, while a stratified random sampling technique was used. 1,600 samples made up of 600 students in each of the three districts were used. Data collection was conducted using a self-designed questionnaire and analyzed using t-test statistics. Results showed that there is a significant influence of students’ participation in the maintenance of school discipline on the effectiveness of principals. The study has shown that students’ participation in choosing their leaders influences principals’ effectiveness;students’ participation in co-curricular activities and in the formulation of school rules have significant influence on principals’ effectiveness. It is recommended that private secondary school students in Lagos State of Nigeria should be allowed to participate in the maintenance of school discipline, the choice of their leaders, and the formulation of school rules and co-curricular activities to ensure the smooth and effective operation of school administration.

Molecular Sexing and Taxonomic classification of Nigerian Guinea Fowl using Chromo Helicase DNA Binding Gene and 12S mitochondrial rRNA gene.

Sexing of birds at early age is very important for efficient selection and breeding; while characterization and taxonomic identification is relevant in conservation of birds’ genetic resources. This study used the genomic DNA of ten (10) guinea fowl keets to determine their sex using agarose gel electrophoresis and sequencing with chromo helicase DNA (CHD) binding genes, they were also characterize taxonomically using 12S rRNA mitochondria genes. The results of this study shows a double band (ZW) for females and a single band (W) for males under Agarose gel electrophoresis view, the Guinea fowl keets sequenced showed some deletions and were closer to Gallus_CHD12 in the phylogenetic tree. The Taxonomic classification result shows that the sequenced guineafowl keets were most related to the Numida meleagris 12S mitochondrial ribosomal RNA. This study corroborate the fact sex of guineafowl keet can be easily identified at genomic DNA level and they can be characterized taxonomically using the 12SrRNA mitochondrial genes.
