The experiments took place in the villages of Pirang (low trypanosomiasis risk), Keneba and Nioro Jattaba (low-to-medium trypanosomiasis risk). In Nioro Jattaba, cows milked once a day while in the other two villages cows milked twice a day. In Pirang and Keneba, 45 calves taken from each village...

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...
