Epidemiology and species characterization of mange in Cheetahs, Thomson's Gazelles and domestic animals in the Masai Mara ecosystem

Mange is a contagious skin disease caused by one or a combination of several species of mites and is spread by direct contact with diseased animals or from various objects, which have been in contact with the diseased animals. The various species of mites affect domestic animals, humans and wildlife and mange is a disease of zoonotic importance.

The impact of agricultural trade support in developed countries on maize prices in Kenya

This study analyses the impact of agricultural trade support in developed countries on maize prices in Kenya, by assessing how maize imports from developed countries affect domestic maize prices. A simulation is carried out to estimate the cost of maize imports if the trade distorting support was removed from developed countries. It is evident from the study, that maize import and simulated import prices are cointegrated with domestic maize prices. This implies that in the long run maize prices in Kenya tend towards prices of maize imports from developed countries.

The supply responsiveness of wheat farmers in Kenya

The major objective of the study was to show how wheat farmers respond to price incentives in Trans-Nzoia,Uasin Gishu, Nakuru, Narok and Nyandarua districts in Kenya. The Prices included in the analysis are the annual and one-year lagged prices of wheat and other competing enterprises in each district. Wheat yield variable and average rainfall distribution for each district are incorporated. Time series data from 1964 to 1983 collected from various sources were analyzed separately per district using the Nerlovian Partial Adjustment model.

Mechanizing land preparation for maize production in Kenya

This study evaluates alternative methods of land preparation for maize production on farms in western Kenya, the results of which may be applicable to regions of similar conditions. People, oxen, and tractors are the three sources of power. Maize production depends on rainfall, and the timeliness of operations is critical. To ensure optimum yields, farmers in the region need to prepare the available acreage for maize planting soon after the onset of the rains. An effective method of land preparation to improve labour productivity is desirable.

The role of Livestock marketing in improving the pastoralists' livelihoods through income generation: the case of the pastoralist communities of Garissa District, Kenya

A large part of Kenya is Arid and Semi Arid Lands (ASALs).The ASALs carry 50% of the livestock and 25% of Kenya's human population (Government of Kenya. 2003). Most ASAL inhabitants are pastoralists and mainly depend on livestock as source of livelihood. Despite many resources available in the ASALs especially livestock, the region characterised by high poverty levels. Therefore, there is a need to examine whether livestock marketing has played the role of translating the livestock resource into income to meet various needs.

Function of the lower intestine and osmoregulation in the ostrich: preliminary anatomical and physiological observations.

The gross anatomy of the lower intestine of the African ostrich (Struthio camelus) was investigated in four adult birds shot in the wild. The presence of 80 cm long paired caeca, and approximately 10 m of colon between ileum and the cloaca was confirmed. Urine, but not faeces, was found in the coprodeum. Retrograde flow into the colon was not observed. Samples of contents from the lower intestine were secured from these birds and the water content, osmolality and concentrations in the supernatant of short-chain fatty acids (SCFA), acetate, Na, K and Cl and pH were measured.

Changes in Soil Chemical Properties in Response to Application of Phosphorus Sources in Legume Sorghum Cropping Systems

Field experiments to evaluate effect of phosphorus (P) fertilizers and integration of legumes in sorghum cropping systems on soil pH, available nitrogen (N) and P, were conducted in Njoro Kenya during the short (SRS) and long rain seasons (LRS) of 2012 and LRS of 2013. The experiments comprised either lupin or chickpea grown with sorghum. The design was a split plot in a randomized complete block design. Main plots were cropping systems; sorghum monocrop, legume - sorghum rotation and legume- sorghum intercrop.

An evaluation of the effects of information and technology characteristics on technology choice and adoption: The case of Striga and stemborer control technologies in maize production in western Kenya

Population is increasing, thus leading to increased demand for food, especially maize which is a staple food for most of the Kenyan population. Demand for maize in Sub Saharan Africa is projected to double to 52 million tons by 2020 (pingali and Pandey). The increasing population has also caused the per capita farm holdings in Kenya rural areas to become smaller due to continuous sub-division. Besides the reduced farm holding, maize production is constrained by both biotic and abiotic factors.

Investigation on the prevalence of antimicrobial residues in milk obtained from urban smallholder dairy and non-dairy farming households in Dagoretti Division, Nairobi, Kenya

To assess the prevalence and the level of awareness of the risk posed by antibiotic residues among the urban dairy and non-dairy farming households using a household survey and laboratory analysis of milk samples. A cross sectional study. Urban small holder dairy farming and non-farming households in Dagoretti division, Nairobi. The prevalence of antibiotic residues in dairy household milk samples was 4% (11/259) and in milk samples from non-dairy neighbouring households the prevalence was 0.07% (1/136).
