The PhD project is on “Comparison of the performance traits between indigenous cattle and its crossbreds   in Rwanda. This involves the analysis of data generated on production and reproduction of different cattle genotypes at different Research Stations in Rwanda.


The project aims are to study the average levels and variability in performance traits of indigenous and their crossbreeds in Rwanda, using animal performance and pedigree records.

Specific objectives include;

  1. To compare average performance and variability in performance between Ankole cattle and their crossbreds.
  2. To investigate levels of performance of Ankole cattle and their crossbreeds in various production environments of the country
  3. To study the influence of environmental factors, such as temperature and humidity, on production in Ankole cattle and crossbred.
