ORGANIZATIONAL COMMITMENT OF AGRICULTURAL EMPLOYEE’S JOB SATISFACTION IN OGUN-OSHUN RIVER BASIN(OORBDA), OGUN STATE, NIGERIA

This study determined the effect organizational commitment on employee's job satisfaction in Ogun-Oshun River Basin, Ogun State, Nigeria. Data were collected through a structured questionnaire on one hundred and ten (110) respondents using simple random sampling techniques. Data were analysed using descriptive and inferential statistical tools such as Chi-square and Person Product Moment Correlation. Results revealed the mean age of respondents in the study area was 42 years and majority (63.6%) were males. Also, Majority (92.7%) of the respondents perceived that organizational commitment is high in the study area. Reasons adduced for this was punctuality at work (=4.40) and co-operation with colleagues to facilitate completion of tasks within the organization (=4.39). More so, major satisfaction indicators were advancement for promotion ( = 4.20) and right to enjoy leave (=4.01). The results also show that significant relationship existed between income(r= 0.035, p< 0.05), sex (χ2= 55.12, p < 0.05), marital status (χ2= 241.40, p<0.05), organizational commitment (r= 0.417, P < 0.05), constraints faced (r=0.528, p< 0.05) by respondents and their job satisfaction. The study concluded that employees enjoy cooperation from the organisation and factors that will enhance employee’s commitment in attainment of organisational sustainability is highly recommended.   &nbsp

EFFECTS OF AESTIVATION DURATION ON REPRODUCTIVE TRACT DIMENSION AND SPERMATOZOA PRODUCTION OF GIANT AFRICAN LAND SNAIL (Archachatinamarginata) DURING DRY SEASON

Aestivation is a process of metabolic suspension which plays a key role in the survival of land snails during a period of drought. Human shave also used this process to transport the animal for commercial purpose. To examine the effect of this physiological process on reproductive apparatus, thirty (30) Giant African Land snail (Archachatinamarginata) with average weight of 130 -150g were used for this study. The snails were allotted to three different treatments with ten (10) replicate each after four weeks of acclimatization period which include: zero (0) week, three (3) weeks and six (6) weeks of aestivation. Parameters measured were: Internal organ weight, ovo-testis weight, reproductive tract length (cm) and weight (g). Also gonado-somatic index and spermatozoa concentration were also determined. Results showed that aestivation duration had significant influence on organ weight, ovo-testis weight, reproductive tract length and weight and spermatozoa concentration. However, gonado-somatic index (GSI) was not significantly influenced. It was observed that organ weight decreased as aestivation duration increased. For ovo-testis, snails with aestivation duration of six weeks had smaller weight compared to the control (0 week) while those at three weeks aestivation duration were not significantly different from the control group and those of six weeks aestivation duration. For reproductive tract weight, there was a significant(P<0.01)decrease in weight of the tract for both snails under three and six weeks aestivation duration compared to the control group (0 week). Spermatozoa count also decreased as aestivation duration increased. It can therefore be concluded that aestivation duration had significant effect on organ weight, ovo-testis weight, reproductive tract weight and spermatozoa concentration. For quick target of reproduction and snail economic value, it is recommended that aestivation duration should not be allowed to reach three weeks and above for whatever reason.     &nbsp

Comparative evaluation of inhibitory activity of Epiphgram from albino and normal skinned giant African land snail (Archachatina marginata) against selected bacteria isolates

A study was conducted on evaluation of inhibitory activity of epiphgram from albino and normal skinned giant African land snail (Archachatina marginata). After aestivation, epiphgram were collected from twenty snails (10, albino and 10 normal skinned). The epiphgram were washed, air dried and ground into powder form. Minimum inhibitory concentration (MIC) of epiphgram from both albino and normal skinned species were determined by standard broth micro-dilution method using four (4) clinical bacteria Isolates which include: Eschericia coli, Pasteurella species, Salmonella species and Staphylococcus aureus. Ciproflaxacin antibiotic was used as control. Result showed that epiphgram from both albino and normal skinned snails had higher microbial activity for both Eschericia coli and Salmonella species as shown by minimum inhibitory concentration (MIC: 0.050 and 0.098 vs 0.098 and 0.049) compared to streptomycin (MIC: 78 and 1.95 vs 15.63 and 1.95) which is the control. However, normal skinned epiphgram had higher antimicrobial activity considering the MIC values for Salmonella species, Staphylococcus aureus and Pasteurella species. While MIC value recorded for Eschericia coli showed that albino snail epiphgram had higher antimicrobial activity in the elimination of this bacteria species better than the normal skinned. It can be concluded from this study that substance which eliminate bacteria especially the four bacteria isolates used in this study are present in the epiphgram of both normal and albino snails in varying proportion with the highest amount present in normal skinned snail’s epiphgram except for Eschericia coli.Keyword: Albino snail, Archachatina marginata, Inhibitory activity, Epiphgram, Bacteria isolat

Fisherfolks’ Perception of the Agricultural Radio Programme Filin Mainoma in Kainji Area of Niger State

The study examined fisherfolks’ perception of the agricultural radio programme FILIN MAINOMA in Kainji Area of Niger State. Multi-stage sampling technique was used to select 252 respondents from the study area. Primary data were collected using structured interview guide. Data collected wereanalysed using descriptive and inferential statistics such as, Pearson Product Moment Correlation Coefficient (PPMC) and Chi-Square analysis (c2).  Results showed that the mean age of the respondents was 25.50 years while majority (96.60%) was male. Also 63.10% had no formal education while 22.70% had primary school education. Also, Majority (99.20%) of the respondents was aware of and listened to the radio programme FILIN MAINOMA. All (100.00%) of the respondents had access to radio. Majority (98.80%) of the respondents opined that the message was interesting, 67.10% spent one hour listening to the radio programme in the morning every day. In addition, 38.90% of the respondents viewed fishing information on the radio programme as relevant, while 26.90% indicated that the format of presentation of the programme aroused their interest. Chi-Square analysis revealed that sex (c2 = 78.70, (p<0.05), df = 1), educational status (c2 = 2.41, df = 4), had significant association with the respondents perception of the programme. Also, correlation analysis results revealed a significant and positive relationship between the household size (r = 0.21, p<0.05), and year of membership association (r = 0.24, p<0.05), and respondents’ perception of the radio programme. The study concluded that FILIN MAINOMA had impact on fisherfolks cash per unit effort. The study recommended that the programme should be strengthened and sustained while other similar programmes can be initiated in other radio stations in the area

COMPARATIVE MORPHOLOGY OF HAEMOCYTE FROM TWO SPECIES OF GIANT AFRICAN LAND SNAILS (Archachatina marginata AND Achatina achatina)

A study was conducted to evaluate the presence and types of haemocytes inherent in haemolymph of two species of giant African land snails (Archachatina marginata and Achatina achatina). Haemolymph samples were obtained from three liveweight groups of snails (< 100 g, 101-150 g and >150 g) after removal of the first three whorls of the shell. Smears were made from thin layer of settled portion of the haemolymph after six hours. Staining was carried out after air drying at room temperature with MayGrünwald-Giemsa stain.  Four replicates per liveweight per species were used. Representative slides were selected after viewing under microscope. Dimensions of haemocytes identified were taken followed by photomicrograph. Results showed that four haemocyte types were present in the haemolymph of both species. Those haemocytes identified in Archachatina marginata had significantly (P<0.001) higher dimensions than those found in Achatina achatina. Morphologically, the haemocytes were different in terms of shapes, nucleus position and cytoplasm types. It can therefore be concluded from this study that four circulating haemocytes types are present in both Archachatina marginata and Achatina achatina. Furthermore, in terms of dimension, Archachatina marginata had higher values compared to Achatina achatina. Also, morphologically, those four haemocyte types are different from each other in both specie of giant African land snails.Â

HIV sexual risk behaviors and perception of risk among college students: implications for planning interventions

<p>Abstract</p> <p>Background</p> <p>The college environment offers great opportunity for HIV high-risk behaviors, including unsafe sex and multiple partnerships. While the overall incidence of HIV infection has seen some decline in recent years, rates of HIV infection among young adults have not seen a proportionate decline. As in the general population, African American young adults have been disproportionately affected by the HIV/AIDS epidemic. This study examined the sexual risk behaviors and perception of HIV risk of students in a predominantly African American commuter urban university in the Midwest.</p> <p>Methods</p> <p>Students enrolled in randomly selected general education courses completed a paper and pencil survey. Data were collected in Fall 2007, and univariate, bivariate, and multivariate analyses were conducted using SPSS for Windows v.16.</p> <p>Results</p> <p>The sample included 390 students, the majority (83%) of whom were never married and 87% were sexually experienced. Among males reporting male partnerships those who used marijuana (OR = 17.5, p = 0.01) and those who used alcohol along with illegal drugs (OR = 8.8, p = 0.03) were significantly more likely to report multiple partnerships. Among females reporting male partnerships, those 30 years and older were significantly less likely (OR = 0.09, p = 0.03) to report having multiple male partners. There were significant differences in condom use last sex (p = 0.01) and consistent condom use (p = 0.002) among the different age groups. Older students were less likely to report condom use. Females age 30 years and older (OR = 3.74, p = 0.05) and respondents age 2029 years (OR = 2.41, p = 0.03) were more likely to report inconsistent condom use than those below 20 years. Marijuana use was correlated with inconsistent condom use (p = 0.02) and alcohol with not using condom last sex among females. Perception of HIV risk was generally poor with 54% of those age 30 years and older, 48.1% of 2029 year olds, and 57.9% of those below the age of 20 years perceived themselves as not having any chance of being infected with HIV. Predictors of moderate/good perception of HIV risk were drug and alcohol use, inconsistent condom use, and multiple partnerships.</p> <p>Conclusion</p> <p>Students in the study sample engaged in various HIV risk behaviors but have a poor appreciation of their risk of HIV infection. While low rates of condom use was a problem among older students (30 years and older), multiple partnerships were more common among younger students, and marijuana and alcohol use were related to low condom use among females. Our findings support the need for targeted HIV prevention interventions on college campuses.</p

MEAT QUALITY AND LIPID PROFILE OF BROILER CHICKENS FED DIETS CONTAINING TURMERIC (CURCUMA LONGA) POWDER AND CAYENNE PEPPER (CAPSICUM FRUTESCENS) POWDER AS ANTIOXIDANTS

This experiment was designed to determine the meat quality and lipid profile of broiler chickens fed diets containing turmeric (Curcuma longa) powder (Tur) and cayenne pepper (Capsicum frutescens) powder (Cay) as antioxidants. Two hundred and forty three (two-week old) Abor Acre broiler chicks were randomly allotted to nine treatment groups of 27 birds each, consisting of three replicates of nine birds each in a completely randomised design. Three levels of Tur (0, 2 and 4 g/kg) and three levels of Cay (0, 1 and 2 g/kg) were used to provide nine dietary treatments.&nbsp; Meat quality indices such as cook and refrigerated losses, water absorptive power, etc were measured and determined at the 8th week. Broiler Chickens fed the basal diet had highest meat dry matter, protein content and least (p&lt;0.05) meat pH, cook and refrigeration loss values. Meat triglyceride and meat malondialdehyde value was best (p&lt;0.05) in treatments fed dietary 2 g/kg Cay, while chickens fed 2 g/kg Cay, 2 g/kg Tur + 1 g/kg Cay and 2 g/kg Tur + 2 g/kg Cay had better meat lipoprotein values. For meat sensory characteristic, meat flavour of broiler chickens fed diets containing 2 and 4 g/kg dietary Tur, were&nbsp; moderately liked while overall flavour was best (p&lt;0.05) in groups fed the basal diet with no dietary additive. It was evident in the study that the dietary inclusions of the test ingredients limited lipid oxidation, thus improved storage duration and meat flavor. &nbsp; &nbsp

Evaluation of Pasting Properties of Plantain, Cooking Banana, Selected Cereals and their Composites as Indicators for their Food Values

The pasting properties of unripe plantain, unripe cooking banana, some selected cereals and their composite flours were investigated in relation to their food values. Each of the samples was cleaned, air–dried and pulverized to form the native flours which were mixed in different proportions to form the composite flours. Soft doughs were prepared from the flours and subjected to textural evaluation. The adjudged best from each set was analysed using Rapid Visco–Analyser followed by determination of their proximate composition and functional properties. The results showed that the breakdown viscosity (cP) of each of the composite flours was less than 920.50 in plantain and 915.50 in cooking banana, indicating improved ability to withstand shear stress. The values of the final viscosity of the composite flours were generally lower than the native flours of plantain and cooking banana which indicated better flow property. The setback viscosities of the composite flours were lower than the native cereal flours except sorghum which indicated lower tendency to undergo retro–degradation. Furthermore, the composite flours gelled at lower temperature (72.1–84.9 °C) when compared with the native flours (82.7–89.2 °C) reflecting less energy requirement for cooking. Combination of cereals with plantain or cooking banana had led to production of composite flours which gave better and improved pasting properties without depreciation in functional properties and nutritional composition.
