Four experiments were carried out in which supplements of locally available proteinaceous by-products were given to young, mainly pre-weaned calves that ranged in initial weight from 30 to 90 kg. The experiments were part of a programme designed to establish practical and economical nutrition int...
A study undertaken to determine the performance of crossbred cows on the smallholder farms in southern Malawi with respect to reproductive and productive performance traits. Includes data on age at first calving, calving interval, and milk yield.

A study was undertaken to determine the effectiveness of a progesterone-releasing intravaginal device (PRID) and prostaglandin F2 alpha (PGF2a) in synchronizing oestrus in N'dama and Bunaji cows and heifers and the fertility following artificial insemination at the synchronized oestrus. A total o...

The effects of trypanosome and helminth infections on health and production parameters in 2000 village N'Dama cattle were assessed periodically. Blood examination showed Trypanosoma congolense and Trypanosoma vivax to be prevalent, while strongylid-type eggs were those most frequently encountered...

Current cereal breeding programmes at commodity-oriented research centres emphasize grain yields with little consideration for fodder yield and quality. In farming systems with livestock, the use of varieties with high-grain yields but low stover yields may be rejected by farmers. This study inve...
