Journal of Agricultural Extension , 2009,
Abstract: The study aimed at examining the effect of loan utilization on the output of youth rice farmers in Shiroro Local Government Area of Niger State. The specific objectives are to determine the socio-economic characteristics of the respondents, determine whether there is significant difference in output of the beneficiaries and non beneficiaries and compare the mean output of the youth farmers with and without credits facilities. To achieve the study objectives, 100 respondents from 10 wards was used for data collection. The collected data analyzed using simple descriptive statistics and T-test was used to compare the mean output of credit beneficiaries and non- beneficiaries. The study revealed a significant difference in the mean output of rice farmers who utilize loan (1,375kg/h) with those without credit which was (275kg/ha) (t-cal=18.44,p<0.05). It was recommended that, the process of acquiring loan should be simplified to encourage and motivate rice growers to acquire loan in order to increase their productivity as well as improve their standard of living. Also farmers on their part should be encouraged to pay back loan obtained.

R.S Olaleye, I.S Umar, M.A Ndanitsa
Journal of Agricultural Extension , 2009,
Abstract: Generally, the study examines the effect of dry season tomato farming on poverty alleviation among women farmers in Niger State, Nigeria. Specifically, it examines the demographic and socio-economic characteristics of the women dry season tomato farmers, their major sources of resources for tomato farming, marketing and marketing channels for tomato produced as well as the monthly income generated from the sales of harvested tomatoes and the effect on poverty alleviation in terms of provision for food, clothing, housing, health care and children’s education. Three Local Government Areas (LGAs), from each of the three geo-political zones of the State were purposively selected .A total of 15 villages were randomly selected from these LGAs and based on the preponderance of women tomato farmers, respondents were purposively selected to give a total of 233 . Findings showed that over one-half of the respondents (52.4%), had formal education and married (53.2%), with majority (91.3%), of them having four and more people in their households.Morever,41.6% of the women practiced farming as their major occupation. Furthermore, over two-thirds of them cultivated 0.5ha of tomato farm, while only 2.1% of them cultivated above 1ha. Findings indicated that majority of them had more than four years tomato farming experience and access to farm land was never a problem but many of them (51.9%), relied mostly on family labour. Niger State Agricultural Development (NSADP) plays a leading role in the provision of relevant technical information to most of the women farmers especially, in the areas of improved seed varieties among others. Results showed that many of the women (61.7%),usually sold their produce at the village markets ,mostly every week either in retails or in bulks or both(47.6%) with an estimated monthly income of between N6,000 and N15,000 by many of them (63%).In view of this, their expenditure performances indicated that many of the women farmers were above average in meeting the following basic needs; food (52%), clothing (48.1%), housing (57%),health care (39.9%) and children’s education (19.4%).Generally the effect of dry season tomato farming on poverty reduction as indicated by majority of the women farmers was on the high side. Chi-square tests showed significant relationships between some independent variables and the effect of dry season tomato farming as strategy for poverty reduction; household size ((Χ2=246.29,P<0.05), children’s education (Χ 2= 353.3,P<0.05) and tomato farming experience (Χ 2 =121.7, P<0.05 ) as well as correlation between income generated and the effect of dry season tomato farming (r=0.85, P<0.05).Cobb-Douglas multiple regression analysis model showed a significant relationship between contributions to household expenditures and the effect of dry season tomato farming (F=6.54,P<0.05). Housing (t= -3.85,P<0.05), clothing (t=-3.56,P<0.05) and food(t=-2.31,P<0.05) were inverse but significant in explaining 62% variation i

International Journal of Tropical Medicine , 2012,
Abstract: The present study, was undertaken to assess the prevalence and pathology of brain disorders in cattle. The data collected from the autopsy records (99 bovine carcasses) maintained at the Center of Excellence in Pathology, College of Veterinary and Animal Sciences, Mannuthy, India and 52 brain samples obtained from both the slaughtered cattle and autopsy cases formed the basis of the study. The only gross lesion evident was meningeal congestion, which accounted to 70% of the cases. Congestion and hemorrhages were found consistently in the slaughtered cattle. The other major lesions were revealed by histopathological examination of 10 different areas of the brain in each case. These included vascular changes, neuronal degeneration, inflammatory changes, gliosis, pigmentation and neoplasia. Two cases revealed cytoplasmic inclusions of which one was due to rabies and the other was attributed to unknown viral etiology. Based on the observations made here, it is evident that incidence of pathological disorders encountered is relatively high. Thus, the need and scope for investigation into the pathological disorders of bovine brain warrants further investigation.

Time Budget in Two Desert Gerbils: is the Diet Important?
Khokhlova, I.S.,Krasnov, B.R.,Kuznetsov, V.,Sartor, C.E.
Agriculturae Conspectus Scientificus (ACS) , 2003,
Abstract: We studied time budgets and dietary intake in two desert gerbillids, Psammomys obesus, a diurnal herbivore, and Meriones crassus, a nocturnal granivore feeding three different types of diet (millet seeds together with leaves of Atriplex halimus for M. crassus, fresh leaves of A. halimus or fresh stems of Anabasis syriaca for P. obesus). M. crassus spent the lowest proportion of its time budget for feeding compared to P. obesus. Number of feeding sessions in M. crassus was approximately the same but each separate feeding session was almost three times shorter than those in P. obesus. No difference in temporal pattern of feeding was found between P. obesus fed different plants, in spite of sharp differences in chemical composition of food. P. obesus fed A. halimus was active significantly less time than M. crassus, whereas P. obesus fed A. syriaca stayed active the same time as M. crassus. Dry matter intake of P. obesus fed A. halimus was much higher than that of M. crassus and dry matter intake of P. obesus fed A. syriaca was lower than even that in M. crassus.
