Milk production of Ankole crossbreds and Holstein Friesian cattle in different production environments of Rwanda

Article scientifique 2022 Anglais

Résumé

Abstract The aim of the study was to assess the productive performance of dairy cattle in three different agroecological zones of Rwanda: Congo-Nile/Western, Central plateau/Central, and Eastern plateau/East agroecological zones. A single-visit multi-subject survey was conducted to obtain information on the dairy cattle performance from 51 farms. The breed groups were classified as Ankole x Holstein Friesian (AF), other Ankole crossbreds (AX) and pure Holstein Friesian (F). F had higher milk yield than AF in all zones and AF had higher milk yield than AX, except in the Western zone. Across all zones, F produced 10 L more than AX and 6 L more than AF per day. Cows in the Eastern zone had the highest milk yield, which was contrary to our expectation, because the Western zone receives more annual rainfall, and hence should have a better pasture level. The large difference in performance of Holstein Friesians and its crossbreds in different agroecological zones indicates that considerable improvement could be achieved by improving the production environment.
