DIGESTIBILITY AND NITROGEN UTILIZATION OF SEMI INTENSIVELY MANAGED WEST AFRICAN DWARF SHEEP FED NEEM LEAF MEAL CONCENTRATE

Ruminant livestock production in sub-Saharan Africa is based on forage as the major feed resources, which of course is highly seasonal with low nutritive quality during dry seasons. Neem leaf (Azadirachta indica) when added to livestock feed has been found to reduce the problem of feed scarcity which are serious problems of the developing world. […]

DETERMINATION OF LEVELS OF VOLATILE ORGANIC COMPOUNDS (VOCS) IN WARRI AND EFFURUN ENVIRONS, DELTA STATE, NIGERIA

Abstract Six air samples were collected from six locations in Warri and Effurun environs and were analysed for Volatile Organic Compounds. (VOCs) After treatment of samples, VOCs were determined with Gas Chromatography coupled with Flame Ionization Detector (GC / FID). Results obtained showed concentrations of VOCs in the range of 0.42 – 28.78, 0.32 – […]

NITROGEN SOURCES AND THEIR EFFECTS ON NITROUS OXIDE EMISSION AND MAIZE YIELD IN WESTERN KENYA

Abstract This study assessed the effect of applying inorganic or organic sources of nitrogen, or their combination, on N2O emission, maize yield and Nitrogen Use Efficiency (NUE) at Nyakach, a lowland and Soin, a highland in western Kenya. A randomized complete block design, was used with six treatments; a control with no N input, urea […]

EVALUATING THE IMPACT OF EXTENSIVE AGRICULTURAL ACTIVITIES ON INDOOR GASEOUS, PARTICULATE POLLUTANTS AND BIO-AEROSOL LOAD

Abstract This study monitored particulates, gaseous and bio-aersosol pollutants in 211 indoor sites across residential farm settlements in Southwestern, Nigeria between December 2017 to July 2018 covering dry and wet seasons. Gaseous and particulate pollutants were monitored with potable active air samplers for gaseous and particulates, and open-plate sedimentation technique for bacteria and fungi. Data […]

ACCUMULATIONS AND ALTERATIONS IN THE TISSUES OF ALBINO RATS TREATED WITH LEAD METAL AND ITS ELIMINATIONS USING Cocus nucifera L. WATER

Abstract This study was carried out to determine the accumulations and alterations in some tissues of albino rats treated with lead metal and its eliminations using Cocus nucifera water. Forty-eight healthy albino rats of approximately 154g were distributed into 4 groups of 3 replicates with 4 rats each. 4g/kg bwt of lead nitrate dissolved in […]

MICRO-LEVEL ANALYSIS OF AGRO-PASTORALS’ ADAPTATIONS TO CLIMATE CHANGE IN ETHIOPIAN SOMALI REGION

Abstract The study identifies types of adjustments agro-pastoral households are making in their crop and livestock production practices in response to climate changes, and factors influencing the probability of choosing adaptation mechanism at their disposal. Primary data were collected from randomly selected 156 agro-pastoral households. The survey data were analyzed using descriptive statistics and multinomial […]

SOIL EROSION RISK DETECTION BASED ON REVISED UNIVERSAL SOIL LOSS EQUATION (RUSLE) IN THE COPPERBELT WATERSHED, ZAMBIA

Abstract Despite the general concerns of soil erosion as a major cause of land degradation emanated by human activities and natural settings, information on soil loss is not readily available in some areas under different land use systems since no studies have been done to establish the erosivity of the land. An attempt was made […]
