Summary

The research was done in the Valley of the river Beles, a tributary of the Blue Nile, in the Goggiam region of Ethiopia. Three types of ground (called Black, Red and Brown) were each divided into two fenced areas measuring 2 sqm, one in the shade and the other in the sun. In each area samples of the natural growth were cut 3 times during the rainy season. The 18 samples of natural growth were chemically analysed. Data were processed statistically and grouped according to soil type, time of cut and kind of cover. The differences between samples can all be imputed largely to the parameter “soil-type”. In fact flora growing in the Red-soil yielded the best levels of crude Protein as well as the lowest quantity of crude Fibre thus resulting the most digestible. Moreover the Red-soil produced fodder with the best levels of energy value due to the high levels of Nitrogen-Free Extract and Ether Extract. On the other hand, the Brown soil proved the worst despite it being the most productive. It yielded the smallest quantity of crude Protein, N.F.E. and Ether Extract and the greatest of fibrous matter. In all areas the yeld in mineral elements were poor; Calcium resulting the most deficient. The same tendency was seen with Sodium whose concentration was insufficient to satisfy an animal’s requirement especially in tropical conditions. Therefore, a suitable supplement to the natural flora would be necessary to insure adequate nutritive substances and mineral intake, especially in the Black and Brown soils.
