Seasonal Parasite Carriage Of Village Chicken In Mbeere Subcounty, Antiparasitic Treatments Used And Effectiveness Of Selected Anthelmintics

Endo- and ecto- parasites are common among village chicken; as they scavenge and forage for food they tend to pick up infective stages of the parasites. These parasites are a major cause of stress to birds where they compete for nutrients, some suck blood causing anaemia, interfere with feed consumption, while others cause anorexia or death. High parasite burden leads to severe parasitism.

White Lupin (Lupinus albus L. cv. Amiga) Increases Solubility of Minjingu Phosphate Rock, Phosphorus Balances and Maize Yields in Njoro Kenya

Exudation of high amounts of citrate in white lupin (Lupinus albus L. cv. Amiga) has the advantage of being effective in mobilization of a wide range of sparingly soluble P sources. To improve cultivation system of maize, a field experiment was conducted to assess effectiveness of white lupin (Lupinus albus L. cv. Amiga) in increasing solubility of minjingu phosphate rock (MPR), phosphorus balances and maize yields in Njoro sub-County, Kenya.

Dry Spell Analysis And Maize Yields For Two Semi-arid Locations In East Africa

High variability in rainfall occurrence and amounts together with high evaporative demand create severe constraints for crop growth and yields in dry sub-humid and semi-arid farming areas in east Africa. Meteorological analyses on rainfall distribution are common, but generally focus on assessing drought occurrence on annual and seasonal basis. This paper presents two types of seasonal dry spell analysis, using easy accessible data on daily rainfall and evapotranspiration for two semi-arid locations in east Africa for 20–23 years.

Antimicrobial residues detected in marketed milk in urban and rural areas in Kenya

Anti-microbial agents are widely used in Kenya for the treatment of diseases in both man and animals. Of major public health concern is the possible presence of anti-microbial residues in milk that is not withheld from human consumption or due to addition by market agents as preservative. This is aggravated by inadequate national anti-microbial residue surveillance and control programme in Kenya. A study was therefore conducted to establish the extent of contamination of marketed milk by anti-microbial residues in urban and rural areas in Kenya.

Effect of clump planting of maize and time of planting of beans on growth and yield of intercropped maize and beans

Two field experiments were conducted at the University of
Nairobi's Faculty of Agriculture Kabete, to investigate
the merits of clump planting of maize and time of planting
of intercropped beans on growth and yield of the maize and
beans. Effect of the treatments on field weed load was
also examined. Three clumping patterns of maize and three
planting times of beans were tested in a factorial
experiment laid out in a completely randomised block
design with three replications. The clumping patterns of

Microbial Performance of Food Safety Control and Assurance Activities in a Fresh Produce Processing Sector Measured Using a Microbial Assessment Scheme and Statistical Modeling.

Current approaches such as inspections, audits, and end product testing cannot detect the distribution and dynamics of microbial contamination. Despite the implementation of current food safety management systems, foodborne outbreaks linked to fresh produce continue to be reported. A microbial assessment scheme and statistical modeling were used to systematically assess the microbial performance of core control and assurance activities in five Kenyan fresh produce processing and export companies.

Sodium hydroxide and amonnia-treated maize stover as a roughage supplement to sheep and beef feedlot cattle.

Trials on wether sheep fed sodium hydroxide-treated maize stover and untreated Rhodes grass hay and on Boran steers fed ammonia-treated maize stover and Rhodes grass hay indicated that sodium hydroxide-treated stover had a similar nutritive value to Rhodes grass hay. Ammonia-treated stover was slightly better than hay at the given intake levels, but at 26% silage replacement level was slightly inferior to silage alone.

A study of factors associated with the prevalence of coccidia infection in cattle and its spatial epidemiology in Busia, Bungoma and Siaya counties, Kenya

Coccidiosis is a protozoan infection that affects most domestic species: canine, feline, equine,
porcine, bovine, ovine, lagomorphs and avian. The overall objective of this study was to
determine the prevalence and spatial distribution of coccidia infection in cattle, and
associated factors in different production systems in Busia, Bungoma and Siaya Counties
Kenya. Specific objectives were to determine the prevalence and spatial distribution of
coccidia infection in cattle as well as assess the factors associated with the infection in these

Management of Mycotoxigenic Fungi and Associated Mycotoxins in Maize by Use of Hermetic Storage

Maize is a staple food crop in Kenya with about 90% of the rural households depending on it. However, the grain is vulnerable to degradation by mycotoxin producing fungi in the field and during storage. Mycotoxins produced by these fungi cause significant economic losses and deleterious health effects to humans and animals. Strategies such as storage of maize in hermetic bags have been developed to reduce post-harvest grain losses due to pest attack, fungal growth and mycotoxin contamination.

Integrated management of bean Bruchid,Acantlloscelides Obtectus say (Coleoptera: Bruchidae), on stored beans in Eastern Kenya

A survey was carried out on stored beans in three districts (Meru central, Meru north and Tharaka) in eastern Kenya to identify the bruchid species responsible for the bean damage and the existing management options currently used against the pest by farmers in the study area. The study established that, Acanthoscelides obtectus Say was the dominant pest species of stored beans and farmers still rely on mainly chemical pesticides in its control in eastern Kenya but damage as experienced by farmers was still high.
