Fodder conservation methods: nutritional values and sheep fattening performances

Abstract

Feeding is the major constraint for livestock production in Burkina Faso. Crop
residues are used as supplement during the dry season. However, their valorization is
limited due to their low nutritional value, partly because of their poor storage
conditions. Hence, this study was conducted to evaluate the nutritional value of crop
residues according to their conservation methods and their effect on sheep
performances in fattening. The study was conducted on farms in the Commune of
Koumbia (Tuy District) and twelve Djallonke sheep were used for the fattening. The
fodder crops used were maize Barka and cowpea KVx745-11P varieties. Fodder were
mowed after grain harvest and stored during four months using two preservation
methods (Traditional versus Improved). These preserved fodders were used for two
months fattening, and the weight gain and economic profitability were assessed. Crud
protein concentrations were better with improved method of maize (7%) and cowpea
(14%) fodders conservation. Daily body weight gain of sheep was similar for both
methods of fodder conservation (94.9-101.1 g/day).
