A pregnant and/or lactating cow needs both maintenance ration and extra energy to produce milk and/grow a fetus. Dry and non-pregnant cows need to be fed only the maintenance ration. Requirements for a 400 kg cow are 0.25 kg DCP, 3.0 kg TDN or 10.8 Mcal of ME, 17 g calcium and 13 g phosphorus. Feeding 25 kg of green maize or good quality sorghum containing one per cent DCP, 14 per cent TDN or 60 Mcal ME, 0.6 g calcium and 0.5 g phosphorus per kg of green fodder, meets requirements, as does eight kg of green berseem or lucerne and 5.5 kg of straw. When wheat straw with 1.5 kg of balanced concentrate mixture or 800 g of groundnut cake is fed, the ration is sufficient to maintain the animal.
