Use this Feed Intake Calculator to calculate the daily feed intake for Angora goats. Enter the data into the table and then click the Calculate Feed Intake button. The results will be displayed in the table at the bottom of the page.


We will use a 35-kg Angora doe with 25 g tissue gain (ADG) and producing 5, 10, or 15 g/day of clean mohair fiber consuming a diet containing 12% CP and 9 MJ/kg dry matter (DM) of ME.
1. Enter body weight (kg)
2. Enter tissue (non-fiber) gain (g/day)
3. Enter clean mohair fiber gain (g/day)
4. Enter dietary CP concentration (% of DM)
Enter dietary ME concentration (MJ/kg DM)
You can use the TDN calculator below and the ME concentration will be entered automatically.

They will be automatically entered into the table to the left.
Clean mohair fiber gain

The ME concentration can be calculated with these simple formulas:
ME (MJ/kg) = TDN (%) × 0.15104 and
ME (Mcal/kg) = TDN (%) × 0.0361.

Enter TDN (%)
ME (MJ/kg)
ME (Mcal/kg)


The approach used to develop predictions of voluntary DM intake by goats was based on an assumption of constant overall efficiency of utilization of metabolizable energy (ME). Therefore, ME requirements from other studies of this project were employed, along with assumptions of efficiencies of ME utilization. In accordance, inputs necessary to predict intake entail factors influencing the partitioning of energy for use in various physiological functions, including production level. It is important to note that input of an unreasonably high level of production given the characteristics of the animal and nature of the diet will result in a comparable unlikely estimate of feed intake.

Examples of predictions of voluntary DM intake for a 35-kg Angora doe with a diet containing 9 MJ/kg DM of ME and 12% CP and producing 5, 10, and 15 g/day of clean mohair fiber are 0.96, 0.98, and 1.00 kg/day, respectively.
