To obtain accurate estimation of feeds required for your cows, it is important to know the stage of lactation (number of days from last calving) and the weight. It is also important to note:
• That milk production decreases gradually from about two-and-half months after lactation.
• Maize stovers (>90 per cent), dairy meal (>85 per cent), napier grass wilted (±40 per cent) and
sweet potato vines (±20 per cent) have different dry matter content.
• A cow (weighing 450kg) in early lactation needs 13 per cent dry matter intake, 20 per cent protein and 1.67 MCal Net energy for lactation.
Start with 3kg maize stovers, 5kg dairy meal, 7.5kg napier grass ad 15kg sweet potato vines. If calliandra is available, substitute 7.5kg sweet potato vines with 3kg calliandra.
Note that water and mineral licks should be availed to cows. Monitor intake and cow’s response to the feeds and adjust when required.
For calves (0-4 months), colostrum, milk or a milk replacer, calf starter and hay or pasture. Feeding will also vary with age.
