Animal welfare: a comparative study of working donkeys in rural and urban/peri-urban areas of Mwingi Central Sub- County Kitui County

Abstract: A cross sectional study was conducted to compare the welfare of working donkeys in the rural and urban/peri-urban areas of Mwingi Central Sub-County of Kitui county in Kenya. The assessment of welfare was based on physical welfare indicators, pathological and external parasite infestation, and physiological welfare indicators including the determination of free fecal cortisol concentration. From a total population of 35,361 donkeys in the study area, a sample size of 396 donkeys wa...

Factors affecting sisal cultivation and adoption in Kiomo division, Kitui county, Kenya

Abstract: Sisal cultivation has the potential of contributing immensely towards the economic development of a given country, resulting to improved standards of living. The exportation of sisal fibre can be a great source of foreign exchange in a given country. Further, sisal related industry can be a great source of employment to the global economy. Moreover, sisal is a drought resistant crop, whose cultivation can lead to effective use of the greater arid and semi-arid land in the Sub-Sahar...

Challenges facing indigenous chicken production and adoption levels of biosecurity measures in selected areas of Makueni county, Kenya

Abstract: Annually Kenya produces about 20 million tons of poultry meat worth KES 3.5 billion and 1.3 billion eggs worth KES 9.7 billion. However Indigenous chicken productivity has stagnated due to limited transfer and adoption of improved technologies such as biosecurity practices by rural households. The productivity of Indigenous chicken has been decreasing in Makueni County despite development agencies, both national and international and county government investing heavily in chicken e...

An assessment of adoption of tissue culture bananas in the semi-arid areas of lower Eastern region of Kenya

Abstract: The importance of bananas cannot be underestimated worldwide. The main study objective was to assess the adoption and commercialization of tissue culture bananas in the riverine areas of the semi-arid areas of Lower Eastern region of Kenya. The specific objectives included determining respondents socio-economic, environmental and policy factors affecting adoption of tissue culture bananas in the region. This study was necessary due to the fact that there were many production gaps t...

Taking the heat : integrating behavioural and physiological variables to predict avian responses to climate change in the Kalahari Desert

integrating behavioural and physiological variables to predict avian responses to climate change in the Kalahari Desert Predicting how species will respond to climate change requires an understanding of how temperature affects behaviour, physiological tolerance limits and adaptive capacity. In this thesis, I investigated the temperature-dependency of physiology and behaviour of birds in the Kalahari Desert of South Africa

Chemical and molecular analysis of the pheromone phenylacetonitrile in desert locust, Schistocerca gregaria Forskål (Orthoptera: Acrididae)

Abstract: The desert locust, Schistocerca gregaria (Orthoptera: Acrididae) is a destructive pest when gregarious but harmless in solitary form. Reports demonstrate the involvement of aggregation pheromones in mediating behavior of the desert locust in the gregarious phase. Phenylacetonitrile (PAN), the major component of the adult aggregation pheromone, can act as an adult aggregant for both sexes and as a male homosexual avoidance pheromone. However, the origin of PAN and its biosynthesis p...

Effects of foliar fertilizer application rates on productivity of selected bean (phaseolus vulgaris l.) varieties

Abstract: Food security is a global problem despite the many efforts put to produce enough food to feed the ever rising global population. Common bean (Phaseolus vulgaris L) is an important crop for food security and provision of proteins for poor households in sub Saharan Africa. In arid and semi-arid lands, beans are very important for they play a major role in food security and nutrition. However, its production in ASALs is constrained by erratic rainfall, moisture deficit, low nutrients ...

Determinants of adoption of forage technologies among peri-urban dairy farmers in the semi-arid region of South Eastern Kenya

Abstract: Semi-arid peri-urban environment holds great potential for dairy development to meet the high demand for milk and become a livelihood support strategy. In support for dairy production, forage technologies were promoted among dairy farmers in order to improve the performance of the sector and contribute to poverty reduction. However, the level and determinants of adoption of selected forage technologies in relation to dairy production is still unknown. To address this, 150 dairy far...

Adaptability of pearl millet (Pennisetum glaucum (L.)R.Br) varieties in the semi-arid kKitui County of Kenya

Abstract: Cereals are important crops grown and consumed globally, regionally and locally. However, world cereal yields have declined due to frequent droughts, erratic and unreliable rainfall especially in sub-saharan Africa. Pearl millet accounts for almost half of the global production of the millet species. Therefore, identifying high yielding pearl millet genotypes with farmer preffered traits and adapted to drought stress is key for food security. The objective of the field study was to...

Assessment of performance indices of frame hivebeekeeping and the traditional technology in Kenyaa case study of Kitui county

Abstract: The study wa s conducted to assess the performance indices of frame hive beekeeping technology. The objectives were to establish the factors influencing the adoption of frame hives within selected beekeeping groups in Kitui County and compare honey production and household incomes among beekeepers using frame and traditional hives . Data were collected through formal inter views by way of a structured questionnaire , in four locations of Kitui County. Systematic random sampling was...

Biomass estimation and utilization of Tarchonanthus camphoratus woodland at Ol Morogi Ranch, Naivasha, Kenya

Abstract: Woodlands cover about 80% of the total land area in Kenya, support 60% of the livestock and are important sources of fuelwood especially charcoal for urban areas. The woodlands of Naivasha, Kenya are dominated by a tree/shrub species Tarchonanthus camphoratus L. which is used for charcoal production using traditional earth kilns. A study focussing on woodland characterisation with respect to species composition and stocking and distribution of T camphoratus and its regeneration cha...

Factors influencing grafted mango (Mangifera indica L.) production in Matinyani division, Kitui county

Abstract: v ABSTRACT Mango ( Mangifera indica L.) fruit is produced and consumed globally, regionally, and locally. The fruit is a potential sou rce of essential nutrients including potassium, phosphorous, magnesium and is an excellent source of vitamin A and C . Mangoes can also be sold to earn income . However, most smallholder mango farmers in Matinyani Sub - county experience lack of clean planting materials, ina dequate production technolo gies , inadequate mango varieties with long pro...

Canthonini (Scarabaeidae: Scarabaeinae) of Gondwana : comparison of male genitalia evolutionary trends and phylogeny

Abstract: The current study is about the evolution and the morphology of dung beetles, subfamily Scarabaeinae. The study includes the systematics of the tribe Canthonini and an exhaustive analysis of the morphological variation of male genitalia including species from the 11 tribes of the subfamily, mainly Canthonini, Ateuchini, Scarabaeini and Coprini. With the aim to go deep in the phylogenetic relationships of the tribe Canthonini, the largest of the subfamily Scarabaeinae, with 91 genera...

Ecology and life history of the Vlei Rat, Otomys Irroratus (Brants, 1827), on the Van Riebeeck Nature Reserve, Pretoria

Abstract: The ecology and life history of the vlei rat, Otomys irroratus (Brants, 1827), were studied in a population on the Van Riebeeck Nature Reserve near Pretoria. Two main procedures were used to collect the basic information and material for the project. First, a permanent live-trapping grid was established where 333 animals were captured, marked, released, and recaptured over a period of 26 months, Second, snap-trapping and live-trapping were conducted elsewhere in the study area for ...
