Feeding farm animals: nutrients & rations
Narrated lesson · press play
Why does one farmer's cattle grow fat, glossy and strong while the neighbour's stay thin and weak on the very same veld? The secret is feeding. In this lesson we meet the seven nutrients every animal needs, sort feeds into concentrates and roughages, watch grass lose its goodness as it ages, and learn to plan a balanced ration — maintenance plus production — for each stage of an animal's life on a Namibian farm.
