Journal Article 1996

Autor: Schaik, G. van Perry, Brian D. Mukhebi, A.W. Gitau, G.K. Dijkhuizen, A.A.

The Murang'a District is situated in central Kenya and is a highland area with a high potential for dairy production. This study was carried out to evaluate the performance of smallholder dairy farms by analysing available data and by simulation modelling. Eighteen case farms were selected non-ra...

Multivariate logistic regression models are mostly used to identify risk factors associated withthe occurrence of particular disease processes. Logistic regression models have also been used as tools for veterinary diagnosis by providing the probability of a particular disease in an individual an...

A whole farm simulation approach was used to assess the economic impacts of five alternative strategies for controlling East Coast fever (ECF), a cattle disease, on farms from two sites in Kenya. The strategies were also ranked using the stochastic dominance criterion to determine the most prefer...

Journal Article 1999

Autor: O'Callaghan, C.J. Medley, G.F. Peter, T.F. Mahan, S.M. Perry, Brian D.

A mathematical description of the transmission dynamics of the tick-borne infection Cowdria ruminantium in commercial beef enterprises in Zimbabwe was used to consider the potential impact of a candidate vaccine to prevent heartwater. The important characteristics of the vaccine were (1) a delay ...

Heartwater, caused by the rickettsial organism Cowdria ruminantium, is a serious constraint to livestock development in much of sub-Saharan Africa. Traditionally, the disease has been controlled by the use of chemical acaricides to control the vector tick. The University of Florida/USAID-supporte...

A pilot study of the economic impact of foot and mouth disease (FMD) in the countries and region of South-East Asia is described. Previous economic impact assessments are reviewed and summarised and a synthesis of these contributions is constructed. A framework for the future economic impact of t...

The association between serum antibody titres to Theileria parva in calves and potential explanatory factors were examined in a longitudinal observational study that was conducted in 5 cohorts of female calves with a total of 225 calves on 188 smallholder dairy farms. The farms were distributed i...

Autor: Perry, Brian D. Young, A.S.

This paper reviews the past contributions of epidemiology and economics to the control of tick-borne infections of cattle in Africa. The factors affecting successful and unsuccessful control are evaluated on a gographical and on a production systems basis, with particular reference to Theileria p...

Autor: Perry, Brian D. Hansen, James

Session one of this report highlights ILRAD's research programs and the modelling needs of ILRAD and FAO. Session two deals with vector and helminth population dynamics with particular reference to ticks, tsetse and helminth. Parasite transmission and host parasite interaction are discussed in se...

Heartwater, caused by the rickettsial organism Cowdria ruminantium and transmitted by ticks of the genus Amblyomma, is considered to be the most important tick-borne disease of cattle in southern Africa, and is second only in importance to East Coast fever (theileriosis) in eastern Africa. This p...
