TABLE 10–4 Adjustment Factors for Dry Matter Intake for Cattlea For non-pregnant beef cows: 
For pregnant cows (last two-thirds of pregnancy): 
where DMI is dry matter intake, kg/d; SBW is shrunk body weight, kg; NEma is net energy value of diet for maintenance, Mcal/kg; Yn is milk production, kg/d; BI is breed adjustment factor for DMI (Table 10–4); BFAF is body fat adjustment factor (Table 10–4); ADTV is feed additive adjustment factor for DMI (Table 10–4); TEMP1 is temperature adjustment factor for DMI (Table 10–4); MUD1 is mud adjustment factor for DMI (Table 10–4). The same environmental adjustments (Table 10–4) are used to adjust intake for all cattle types. Adjustment of Dry Matter Intake relative to forage allowance for animals grazing: 
otherwise: 
where DMI is g predicted dry matter intake per kg SBW using previous equations; pI is kg predicted dry matter intake adjusted for grazing situations; FA is daily forage allowance, g/kg SBW/day; GRAZE is forage availability factor if grazing, %; IPM is initial pasture mass (kg DM/ha); GU is grazing unit size (ha);
