Extract

Forage quality and quantity vary by species, time of year, level and time of fertilizer application and grazing system [6]. Livestock nutritional requirements change with age, rate of gain, weight, date of calving and percentage calf crop [7]. Pasture forage production and livestock forage requirements depicting both quality and quantity need to be compiled by calendar periods to determine optimal pasture programs and livestock systems.

Animal unit months (AUM) and total digestible nutrients (TDN) are the predominant measures of forage quantity produced and required. Neither measurement adequately reflects quality and quantity in forage production and beef requirements throughout the production cycles.
