Evaluation of breed productivity in Africa and ILCA resources for data analysis
Quantifying the magnitude and significance of climate change variables over space and time in Africa is challenging due to sparse distribution of weather stations and poor quality of existing data. Time series climate data generated from remote sensing platforms could provide plausible alternativ...

Tracking the magnitude of climate change and variability with remote sensing data to improve targeting of climate smart agricultural technologies
Reports an experiment conducted by ILCA's Nutrition programme to supplement poor quality grass or crop residues that form the basis of many ruminant diets in Africa. Emphasizes the efficient utilization of readily available resources for optimal animal production, in which the influence of noug c...

Tick populations were observed for a period of 12 months, from October 1991 to September 1992 at monthly intervals on ten Boran (Bos indicus) heifers found at Did Tuyura Ranch in Ethiopia. Four Genera and 12 different tick species were identified from a total of 32052 ticks collected. Of all the ...

Genetic improvement for productive traits in livestock, particularly in cattle, has been very slow and insignificant in the country. One of the main reasons for this is lack of well-organized and usable recorded information on the performance of both the indigenous and crossbreds with exotic geno...
