Digestive efficiency in two small, wild ruminants: the dik-dik and suni antelopes.

A comparative study, using six dik-dik and eight suni antelope, was undertaken to identify similarities and differences that may exist in the digestive process of these two small, East African ruminant browsers. The suni antelope was the more select feeder, preferring the native, Grewia sinilis leaves over that of lucerne hay. Daily forage consumption rate, per unity body weight, was greater in the dik-dik (40.4 g/kg) than for the suni (30.6 g/kg), while daily fluid intake was considerably less (i.e. dik-dik, 68 ml/kg versus suni, 106 ml/kg body weight).

Effect of drying lactic acid bacteria fermented uji on its pasting properties and content of carboxylic acids

The effect of fermentation and drying on the pasting properties and carboxylic acids of pure flours of maize, finger millet and cassava and of composite flours of maize-finger millet and cassava-finger millet were studied. The pasting properties were measured between 30°C and 96°C in a Brabender Amylograph while carboxylic acids from the uji slurries were determined on thin layer chromatography plates coated with 0.25 mm silica gel.

The Occurrence Of Aspergillus Section Flavi In Soil And Maize From Makueni, County, Kenya

Maize (Zea mays L.) is the staple food for most households in both urban and rural areas in Kenya and has an estimated annual per capita consumption of about 125 kg per person, which is among the highest in the world. Ear rot fungi belonging to the genera Fusarium, Aspergillus and Penicillium are the commonly encountered mycotoxigenic agents on maize in tropical regions of Kenya. Amongst the three, Aspergillus genus is the most important aflatoxigenic fungal species that infect maize along the value chain.

Prevalence of cryptosporidiosis in dairy cattle, cattle-keeping families, their non-cattle-keeping neighbours and HIV-positive

This paper reports a study estimating the prevalence of cryptosporidiosis, an emerging zoonosis, in people and cattle in Dagoretti, Nairobi. A repeated cross-sectional survey was carried out among randomly selected cattle keepers in Dagoretti, their dairy cattle

Design And Evaluation Of Solar Maize Grain Dryer With A Back-up Heater

A solar dryer integrated with a simple biomass burner was designed and constructed with locally available materials to dry maize. The dryer was composed of solar collector, drying chamber, back-up heater and airflow system all integrated together. The back-up heater provided alternative heating during cloudy weather conditions or at night when solar radiations were low. The dryer was designed based on climatic conditions of Mau summit located in Nakuru County, Kenya.

Physiology of the dik-dik antelope.

1. The East African dik-dik antelope represents a miniature model ruminant for comparative studies. 2. Dik-diks are browsers, consuming a diet consistently high in fermentable and digestable plant material. 3. Their foregut structure is designed for a relatively rapid passage of food and effective absorption of fermentative products. 4. Dik-dik antelopes are very economical in their use of water, having a low daily water exchange and excreting a highly concentrated urine. 5.

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.

Productivity of Indigenous and Exotic Cattle on Kenya Ranches

A comparison of productivity and adaptability of indigenous (Boran and Small East African Zebu) and the exotic (Sahiwal and Ayrshire) cattle on Kenyan ranches located in semi-arid areas of the Rift Valley Provinces was done. Data sets of the cattle breeds over the 1979-1993 period on Deloraine, Elkarama, Ilkerin, National Sahiwal Stud (NSS) and Oljorai were analyzed by the least squares fixed effects model procedures.

Effect of varying soybean planting density on.maize (zea mays) and soybean (glycine max) yields in a maizesoybean Intercrop system in western Kenya

A study to determine the effect of varying soybean planting density on maize and soybean yields
in maize-soybean intercrops was carried out in Butere and Mumias districts of western Kenya
during the short and long rain growing seasons of 2011 and 2012 respectively. To identify the
predominant crops and understand the associated production practices in the smallholder fanning
system a survey was carried out. Field experiments were laid out in a Randomized Complete

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.
