New Approach in Research to Solve Problems of Dryland Farming in Africa

For quite some time now, Africa has faced food shortages that are largely due to
deterioration of agricultural environments and high population growth rates, leading
to a combination of production pressures. The agricultural problems are particularly
pronounced in dryland farming, and the means to mitigate them have to be mainly of
a low external input nature. A case study from Kenya of an integrated research

Antibiotic residues in milk received by dairy cooperative societies in Kiambu district, Kenya

A survey of antibiotic inhibitors in milk received by dairy cooperative societies in Kiambu district was done qualitatively using microbiological assay method. No antibacterial inhibitors were detected in all the samples tested. Informal discussions indicated a high level of awareness of the withdrawal requirement of veterinary drugs after animal treatment in both farmers and the management staff of dairy cooperative societies. The results show that milk from this area is free of antibiotic residues and farmers could be adhering to the withdrawal requirement of veterinary drugs.

Design and performance assessment of a flat-plate solar milk pasteurizer forarid pastoral areas

A solar milk pasteurizer consisting of flat-plate water-heating collector and a
1.5-mm thick stainless steel cylindrical milk vat was designed and tested in an arid
pastoral area of northern Kenya.The milk vat had a capacity of 80 L and a 50-mm
widehotwaterjacketinsulatedwith38-mmthickfiberglass.Hotwaterproducedby
the collector was used for pasteurizing milk. The optimum quantity of milk that
could be pasteurized by this device under the study conditions was 40 L, and the

The incidence of bovine mastitis in Kenya

Clinical mastitis was recorded in 294 of 3376 cows in 1971, 476 of 4744 in 1972 and 200 of 4595 in 1973. The California mastitis test was applied to 214 cows in 15 herds during 1972, and subclinical mastitis was detected in 200 quarters of 98 cows. Staphylococcus aureus and Streptococcus sp. were the most frequently isolated pathogens followed by Escherichia coli and Klebsiella pneumoniae. More than 20% of cases had more than one pathogen.

Consumption patterns and preference of milk and milk products among rural and urban consumers in semi-arid Kenya

Milk consumption in the semi-arid regions of Kenya is not well understood. A study was carried out on consumption of milk and milk products in the semi-arid region of eastern Kenya. A total of 135 rural and 126 urban households were interviewed. Raw milk was the most popular and was consumed by 99% and 84% of rural and urban households, respectively. Generally as degree of processing increased, the frequency of consumption declined from more than once per day to 1-2 times a week and eventually to occasionally.

Global coffee prices in 2011 and the incomes of the Ankole Coffee producers’ Co-operative Union in Uganda

This research investigates the degree of relationship between the monthly farm gate prices received by the farmer members of the Ankole Coffee Producers’ Co-operative Union, a Robusta coffee producing co-operative in Western Uganda, and the average monthly global Robusta coffee prices for the same months between January and August 2011.

The prevalence of helminths, haemoparasites and ectoparasites in cattle in urban and peri-urban areas of Mwanza city, Tanzania

Parasitism is among the causes of continuous ill-health and lowered productivity in livestock in Tanzania and sub-Saharan Africa as a whole. The present study was carried out at urban and pre-urban of Mwanza city in Tanzania to determine the prevalence of parasite infection in cattle kept by livestock smallholders. A random sample of 27 urban farmers with a total 175 diary cattle and 29 peri-urban farmers with a total of 283 mainly zebu cattle were selected and faecal, ectoparasites and blood samples were collected from each catlle.

Modern technology and sustainable irrigation of small scale dry-land farming in Kitui county, Kenya

The Purpose of this study was to investigate the influence of technology on
sustainable irrigation of small scale dry land farming in Kitui Central District,
Kitui County, Kenya. The study sought to establish the extent to which adoption
of new irrigation technology, gravity free flow irrigation and access to access
to credit has influenced sustainable irrigation of small scale dry land farming.
Descriptive survey research design was adopted. A sample of 150 participants

Waste minimization: water use in a Kenyan milk powder factory

Water consumption was measured in a milk processing plant which primarily produces milk powder and butter. There is no milk powder production in the dry season, when the milk is pasteurized and taken elsewhere for packaging. Distribution of water to differenl ports of the lactory was analysed. The factory's water saving potential is estimated to be 45 per cent during the dry season and 43 per cent during the milk powder production season. Proposals are mode for saving water.

The design, construction and testing of a solar operated refrigeration unit

The project consisted of the design, construction, and testing of an exclusively solar operated refrigeration unit. Direct application of solar energy to refrigeration involved the use of an intermittent absorption refrigeration system. Design specifications were:- 1/8 ton of refrigeration at - 200C evaporator temperature refrigeration process to last 3 hours. Ambient temperature variation from 200C to 350C. Minimum generation period of 3 hours. For the unit, the design procedures to meet system specifications have been explained, and component fabrication processes outlined.
