![]() Use the higher figure in the energy column if the calf is 4 months old.Īppendix II – Energy tables and calculationsĬalculation for maintenance: Maintenance MJ ME (0. ![]() Note: when determining the cow/calf unit energy requirements, use the lower figure in the energy column if the calf is 1 month old. *Young cows at these weights need to put on some weight after calving (for example O.5kg/day) because they have not yet reached their adult weight and therefore need better feed than older cows. Range management to improve grazing distribution effectively increases forage supply by enticing cows to consume underutilized forage, thereby altering the stocking rate relationship in favor of supporting more cows or higher nutrient intake by individual cows. Minimum ME concentration of diet (MJ ME/kgDM) Metabolisable energy (ME) requirement (MJ ME/day) Table 6.3: Cows with suckling calves 1-4 months old, assuming eventual calf weaning weight of 250 kg. (Source: Drought Feeding and Management of Beef Cattle Table 6.3 page 38) The only way to be sure of the nutritional value of a particular batch of food is to have it tested for energy, protein, fibre and dry matterĮnergy and protein requirements of cows with calves WARNING: As can be seen from the table, foods vary considerably in nutritional value depending on growing conditions, stage of harvesting and storage conditions. When fed rolled or coarsely milled to cattle Rangeland management (also range management, range science, or arid-land management) is a professional natural science that centers around the study of rangelands and the 'conservation and sustainable management of Arid-Lands for the benefit of current societies and future generations. ![]() (Note: The metabolisable energy of some grains are less for cattle than for sheep unless they are rolled or milled) (Source: Drought Feeding and Management of Cattle Table 5.2 page 32) IMPORTANT – Note the difference in approximate dry matter (DM) % (ME) Metabolisable energy (MJ/kg DM) Energy and protein contents of common feeds for cattle
