Inadequate nutrition is the main cause of low productivity of livestock in sub-Saharan Africa. The primary feed resources include fodder trees, natural pastures and crop residues. This paper presents results from studies conducted at ILRI in evaluations of these resources. The effect of supplemen...

Insufficient feed supply is a major limiting factor for milk production in the tropics. The aim of this study was to assess the effects of feeding level on live-weight and performance of Zebu (Boran) and crossbred (Boran × Holstein, 50–75% Holstein) lactating cows. Twenty-four heifers of each bre...
