The growth potential of local chickens in Malawi was evaluated by comparing their growth performance under cage-fed and free-range management conditions. Chicks (n = 106) were collected from 39 farmers in 19 villages and individually raised in cages from an average age of 9 weeks to 20 weeks. On...

This paper outlines key factors contributing to the erosion of animal genetic resources and discusses strategic options for policy makers. The ratification of the Convention on Biological Diversity (CBD) in 1993 represents an international consensus to conserve biodiversity including that of farm...

This study was undertaken to estimate the potential genetic gains in milk yield by using several alternative selection criteria which included milk yield and reproductive traits of dairy cattle in Malawi. Applying the selection index procedure, the expected genetic gain in each trait in the diffe...

Over the last two decades, dairy cattle management in Malawi has been oriented towards increasing milk yield per animal. One consequence of this process has been reliance on Holstein Friesian bull semen from temperate regions. The aim of the current study was to evaluate the performance of Holste...

Comparative resistance to different isolates of Ascaridia galli was investigated in a local chicken breed from Jordan (LC) and in the Lohmann LSL white chicken (LW) strain. In two trials, birds of LC and LW were inoculated orally at 1-day old with 250 embryonated A. galli eggs. In the first trial...

This paper describes a study aimed at evaluating the effect of selecting sires based on their breeding values for milk yield estimated in their countries of origin on reproductive performance of their daughters on large-scale dairy farms in Malawi. To do this an analysis was done using 2362 recor...
