| crossbreeding cattle in beef production programmes in kenya. i. comparison of purebred boran and boran crossed with the charolais, ayrshire and santa gertrudis breeds. | data collected on a privately owned ranch located in the machakos district of kenya at approximately 2 degrees latitude south of the equator at an elevation varying from 1,675 to 2,000 m were analysed on five breed groups of cows: (1) purebred boran, (2) 1/2 charolais-1/2 boran (1/2 c-1/2 b), (3) 3/4 boran-1/4 charolais (3/4 b-1/4 c), (4) 1/2 ayrshire-1/2 boran (1/2 a-1/2 b) and (5) 1/2 santa gertrudis-1/2 boran (1/2 sg-1/2 b). the maternal traits evaluated included age at first calving, calving ... | 1984 | 6485110 |
| vector competence of 7 rhipicephalid tick stocks in transmitting 2 theileria parva parasite stocks from kenya and zimbabwe. | the competence of 7 different stocks of rhipicephalus appendiculatus and r. zambeziensis to transmit 2 different stocks of theileria parva was compared by feeding nymphae of each tick stock simultaneously on infected cattle and assessing the infections in the salivary glands of the resultant adult ticks. there were significant differences in the patterns of infection of the 2 stocks (t. parva muguga and t. parva boleni) in the different stocks of ticks, and these differences were shown to be rep ... | 1998 | 9651937 |
| prevalence of besnoitiosis in domestic ruminants in kenya: a preliminary survey. | a preliminary survey on the prevalence of besnoitiosis in domestic ruminants in kenya based on field and farm visits, clinical and post mortem examinations and histopathological examination of tissues and biopsies, showed that goats are the most affected, followed by cattle, while sheep were unaffected. caprine besnoitiosis occurred in a continuous belt in 5 of the 8 provinces in kenya stretching from the coast, eastern, north eastern, nairobi and the rift valley provinces. mandera, in the north ... | 1999 | 10855837 |
| valuing goat genetic resources: a pro-poor growth strategy in the kenyan semi-arid tropics. | goats, "the poor man's cow", provide very important genetic resources that can be exploited for continued improvements of the livelihoods of poor livestock keepers in the semi-arid tropics. this study presents the evaluation of the economic values of goat genetic resources (ggrs) in terms of the important non-market traits embedded in goats and how this information can be utilised to improve livelihoods in semi-arid regions. the results obtained from mixed logit models derived from stated choice ... | 2008 | 18975123 |
| estimating seroprevalence and variation to four tick-borne infections and determination of associated risk factors in cattle under traditional mixed farming system in mbeere district, kenya. | a cross-sectional study of serum antibody responses of cattle to tick-borne disease (tbd) parasites (theileria parva, theileria mutans, anaplasma marginale and babesia bigemina) was conducted on traditional smallholder mixed farms in mbeere district in kenya. the objective was to estimate the infections' seroprevalence and variation and identify associated risk factors. a total of 440 cattle in 80 farms, selected by stratified random sampling from the four divisions in the district, were surveye ... | 2010 | 20434227 |
| observations on rinderpest in kenya, 1986-1989. | rinderpest was confirmed in kenya in 1986, 1987, 1988 and 1989. three epidemiologically distinct events appear to have occurred: repeated outbreaks in west pokot district related to cross-border movement of stock, an outbreak in marsabit district in 1987 (thought to have been caused by illegal movement of cattle, possibly in vehicles, from countries further north) and a series of related outbreaks in and near nairobi between 1988 and 1989 due to the unauthorized movement from abattoirs and holdi ... | 1992 | 1472724 |
| environment and farm factors associated with exposure to theileria parva infection in cattle under traditional mixed farming system in mbeere district, kenya. | the objective of this study was to investigate the relationship between seroprevalence to theileria parva infection in cattle and potential environmental and farm-level effects in 80 farms under traditional crop-livestock system in mbeere district, kenya. a standardized questionnaire was used to collect the effects characteristics as related to t. parva infection epidemiology. serum samples were collected from 440 cattle of all ages for detection of t. parva antibodies by the enzyme-linked immun ... | 2011 | 20835912 |
| rift valley fever outbreak in livestock in kenya, 2006-2007. | we analyzed the extent of livestock involvement in the latest rift valley fever (rvf) outbreak in kenya that started in december 2006 and continued until june 2007. when compared with previous rvf outbreaks in the country, the 2006-07 outbreak was the most extensive in cattle, sheep, goats, and camels affecting thousands of animals in 29 of 69 administrative districts across six of the eight provinces. this contrasted with the distribution of approximately 700 human rvf cases in the country, whe ... | 2010 | 20682907 |
