ABSTRACT Marama bean (Tylosema esculentum) is a highly nutritious plant and is currently regarded as a prospective crop for the future in arid zone agri-ecologies of the world. Starch is a major storage component in higher plants and in marama bean it’s mostly found stored in the tuber. Starch is used in both food and non-food industries. Starch biosynthesis involves groups of committed enzymes. Aims of the present study were to determine the physicochemical and pasting properties of nativ...
ABSTRACT The objective of this study was to determine the effects of dietary Carica papaya seed meal supplementation at different levels on growth performance, feed utilization, survival rate and sex ratio of sexually undifferentiated three spotted tilapia (Oreochromis andersonii) fry. Six treatments (replicated thrice) were designed based on the control (basal diet), 17 α-methyltestosterone (MT) (60 mg) and C. papaya seed meal incorporated into tilapia feed at 5, 15, 25 and 35 g / kg diet ...
ABSTRACT This study evaluated the effects of pelleting and replacing maize with pearl millet (PM) cultivar (Okashana 2) on the production performance and cost efficiency of broilers. The experimental design used in this study was a Completely Randomized Design with a 2 x 3 factorial arrangement of treatments (i.e. two processing methods (grinding and pelleting) and three replacement levels (50%, 75% and 100%). A commercial finisher pelleted diet was used as a positive control. The first expe...
ABSTRACT The objectives of this study were to quantify and characterize the nutritional content of milled Senegalia mellifera milled biomass obtained from nine blocks at Neudamm farm and to determine the dry matter intake (DMI), apparent digestibility and nitrogen retention in female Boer goats fed with Senegalia mellifera bush based feeds. Wood ash (WA), Polyethylene glycol (PEG, 6 000) and Biochar were evaluated as tannin deactivation methods. The milled biomass of S. mellifera was mixed u...
ABSTRACT ■3 W The performance, nutrient digestibility and carcass characteristics of rabbits fed dehydrated sweet potato tops and sweet potato root meal in proportions of 100 : 0. 90 : 10, 80 : 20. 70 : 30, 60 : *40 and 50 : 50 were investigated. There was no significant difference (P>0.05) in daily feed intake. However, rabbits fed diets in proportion of 80 : 20 (T.) recorded the highest daily weight gain and was significantly different (P0.05) was reported for the apparent digestibility o...
ABSTRACT The objective of the study was to screen indigenous forage legumes found in central Namibia and evaluate their potential as fodder and protein source for livestock. The growth rate, biomass yield and nutritional value of four indigenous legumes (Otoptera burchellii, Vigna lobatifolia, Crotalaria argyraea and Cullen tomentosum) and four improved legumes (Lablab purpureus, Medicago sativa, Canavalia ensiformis and Vigna unguiculata) were evaluated in a split-plot design with Single su...
ABSTRACT Hydroponics is a cultivation method of growing plants in water. It is a technology suitable for farming that is under artificially controlled environments but can be adapted to situations where land is a constraint. In Namibia this is a potential method for vegetable cultivation. Hydroponics vegetable production has been demonstrated successfully using a balanced conventional nutrient solution, globally, and therefore, an evaluation of its suitability in Namibia using goat manure so...
ABSTRACT This work is one of the studies commissioned by the EC-FAO Partnership programme on sustainable forest management in African ACP countries to investigate the impacts of fiscal policies on sustainable forest management in Africa. Its main purpose is to evaluate in quantitative terms the forestry fiscal policies in Africa, by examining the factors that might explain the different levels of charge collection and expenditure on forestry in different countries in Africa. Seventeen countri...
Abstract Public sector dominance of forestry practices across the globe impedes realization of local and international forestry development targets despite huge local and international investments in the subsector. The need for private forestry practice as compliment to public initiatives on forestry development therefore becomes imperative. This paper reports the bottlenecks for private farm forestry practices among households in the humid zone of Nigeria where environmental hazards necessit...
ABSTRACT One mechanism by which plants can mobilize organic and inorganic forms of phosphorus (P) in soils is by exudation of low molecular weight organic acids. Laboratory and field trial were carried out during 2011 and 2012 cropping seasons to study the effects of additions of organic acids ( citric, oxalic and tartaric acids) on the mobilization of phosphate of soils from Minna and Mokwa, both in Southern Guinea Savanna of Nigeria. For initial laboratory studies and prior to field cultiv...
ABSTRACT The broad objective of the study was to investigate the socio-economic and cultural dimensions of food security among selected ethnic groups in North Central Nigeria. Specifically, the study was designed to: determine food culture and practices of the respondents; determine the household food security status (energy availability) across ethnic groups; determine dietary diversity of the households across cultures; identify perceived constraints militating against household food secur...
ABSTRACT The purpose of this study was to determine the effects of HIV/AIDS on farm income and food production in Kavango region. Representative farm models of communal farms for each of the two most common farming systems in Kavango region were developed. These are the riverline and inland farming systems, which were then used to determine the levels of farm income and food production at farm level under various HIV/AIDS scenarios in terms of changes in resource availability and gender, bas...
ABTRACT The contribution of Community Radio as a strategy for diffusing agricultural innovations cannot be overemphasized in Kumbungu district. The main objective of the study was to investigate the central importance of local radio network influence on convincing farmers to adopt agricultural innovation. It assessed the Role of Simli Radio in the dissemination of Agricultural Technologies among Farmers in Kumbungu district in Northern Ghana. Purposive sampling technique was used for selectin...
ABSTRACT As the debate on commercialization of Genetically Modified (GM)) crops continue to rage the perspectives of smallholder farmers in Africa regarding this novel technology is increasingly becoming relevant and imperative for both agricultural policy makers and researchers alike. This study assessed underlying constructs characterising smallholder farmers’ perceptions and adoption decision towards the cultivation of GM crops. The study was conducted in the three northern regions of Gh...
ABSTRACT This study was conducted in the Sibbinda constituency of Zambezi region in Namibia to determine and contrast the nutritional values of available browsable plants and to recommend and promote the use of these browsable plants and plant parts as cattle feed supplements during dry seasons. In depth focus group discussions and interviews were conducted to glean indigenous knowledge on how cattle utilize the browse in- situ. A total of 200 households from the Sibbinda constituency were i...
