A study to determine factors affecting health and productivity of camel calves in Marsabit district of Kenya

Camel rearing is faced with challenges ranging from low growth rates and high mortality in camel calves within the Arid and Semi-Arid Lands (ASALs) Livestock Production systems in Kenya. A study was conducted on the major factors associated with health and production of camel calves in Marsabit district of Kenya. The main objective of the study was to identify important health and production constraints in camel calf production in Marsabit District, which forms part of the ASAL areas in Kenya. The study was conducted for a period of twentyfour months from 2005 to 2006.

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.

Some performance aspects of seed maize processing operations

The processing of seed maize includes such activities like drying, shelling, cleaning, sizing or grading, chemical treatment and bagging. Most of these unit operations are capable of affecting the quality of seed if proper control is not instituted. The objective of this thesis is to analyse some performance aspects of an existing commercial seed maize processing plant of the Kenya Seed Company Limited. A good portion of this work has dealt with drying and damage to seed during shelling since it was felt that the two areas are more critical in the present situation.

Prevalence of streptococcus a gala ctiae and Staphylococcus aureus in camel (camelus dromedarius) Milk in Garissa and Wajir districts of kenya, their Sensitivity to antibiotics and acceptability of Camel milk and its products

Camel milk is commonly consumed raw by pastoralists in arid areas who may be unaware of the risks posed by such milk. It was therefore very important to determine the prevalence of Staphylococcus aureus and Streptococcus agalactiae, which are some of the most common pathogens in such milk. Camel milk samples from Garissa and Wajir were analyzed to determine the prevalence of Staphylococcus aureus and Streptococcus agalactiae. The antibiotic resistance of the bacteria was also studied. Milk samples (n =207) were aseptically obtained from primary marketing agents.

4th International Maize Nixtamalization Congress

Kenyans are perennially afflicted by aflatoxicoses and chronic aflatoxin exposure. Nixtamalization of maize and maize products has the potential to reduce the levels of aflatoxin in maize in the decorticated maize through physical removal and in whole maize products through chemical degradation. Nixtamalization also has the potential to increase nutrition of maize through releasure of niacin from niacinogen and improve digestibility of protein and starch, as well as the absorption of maize.

The factors influencing the collapse of communal cattle dips after privatization of veterinary services in Kenya: a case of Maara District, Tharaka-Nithi County

This Study is premised on the background that the Livestock farmers in Maara District of Eastern Province of Kenya have stopped using the cattle dipping facilities in the District. The purpose of the study was to find out, from the farmers, why out of the 32 communal cattle dips that were once operating only three are now operational.

Effect of Feed Mixtures and Preservation Period on the Nutritive Value and Fermentation Characteristics of Ensiled Maize Stover

The study was designed to investigate the fermentation processes and subsequent nutritional quality of silage made from dry maize stover, ensiled with selected types of feed mixtures. Stover of maize variety HB614 harvested at about 150 days after planting was chopped into 2.5-cm pieces and mixed with a single or combination of two feed mixtures to constitute 4.5 kg on fresh weight basis in each treatment.

Metabolism and antioxidant defense in the larval chironomid Tanytarsus minutipalpus: adjustments to diel variations in the extreme conditions of Lake Magadi.

Insect larvae are reported to be a major component of the simple but highly productive trophic web found in Lake Magadi (Kenya, Africa), which is considered to be one of the most extreme aquatic environments on Earth. Previous studies show that fish must display biochemical and physiological adjustments to thrive under the extreme conditions of the lake. However, information for invertebrates is lacking. In the present study, the occurrence of the larval chironomid Tanytarsus minutipalpus is reported in Lake Magadi for the first time.

Solar dehydration of cassava for production of flour for local foods in Kenya

Kenyans subsist for the most part on maize and wheat-based foods. The rapid population increase, however, has not been paralleled by a corresponding increase in maize production and has increased the need for wheat imports. This situation has led to the consideration, on a national basis, of the use of composite flours as potential alternatives to expanded maize production and increased wheat importation. This paper reports on the attempts to produce cassava flour for combining with maize meal in ugali, sorghum and millet flours in uji, and wheat flour in mandazis.

Grain maize yield improvement using Tephrosia vogelii and Tithonia diversifolia biomass at Maseno, Kenya

This study aimed at assessing the response of maize crop
to application of Tephrosia vogelii and Tithonia
diversifolia biomass obtained six month-old fallows. The
biomass were chopped into 5-cm long pieces and
incorporated in the soil one week before planting maize.
The natural fallow biomass was used as a control. These
organic inputs were supplied with 20 kg phosphorus (P)
/ha to attain P recommended rates. Shrub aboveground
and litterfall biomass incorporation significantly
