Metabolizable Protein (MP) And Crude Protein (CP) Requirements For Maintenance Of Mature Goats (Meat, Dairy, And Indigenous)

Use this Protein Requirement Calculator to calculate the daily protein requirements for lactation of goats. Enter the data into the table and then click the Calculate Protein Requirements button. The results will be displayed in the table at the bottom of the page.

Example

We will use a 15-pound female or wether goat (6.8 kg) gaining 100 g/day.
1. Enter body weight (kg)
2. Enter dry matter intake in % of body weight (%)

Our example would require a total of 3.23 MJ of ME (1.89 MJ for maintenance and 1.34 MJ for gain).

dry matter intake:

Total ME requirement is the sum of MEm and MEl-d

dmi = in kg/day

bw75 = body weight to the 0.75 power (metabolic body size or weight)

bw60 = body weight to the 0.60 power (relative to surface area)

eump = endogenous urinary MP in g/day

mfmp = metabolic fecal MP in g/day

scmp = scurf MP in g/day

mnmp = total maintenance MP requirement in g/ay

mnmppt = total maintenance MP as % of dry matter intake

mncp20 = total maintenance CP requirement in g/day for a diet that has 20% rumen undegraded intake protein (UIP) (i.e., 80% of CP is degraded in the rumen (DIP); e.g., fresh forage diet)

mncp40 = total maintenance CP requirement in g/day for a diet that has 40% UIP (i.e., 60% of CP is DIP; e.g., mixed forage/concentrate)

mncp60 = total maintenance CP requirement in g/day for a diet that has 60% UIP (i.e., 40% of CP is DIP; e.g., concentrate-based diet, perhaps with inclusion of feedstuffs high in UIP such as blood, feather, fish, or corn gluten meals, and possibly pelletized) in g

mncp20pt = mncp20 in % of dry matter intake

mncp40pt = mncp40 in % of dry matter intake

mncp60pt = mncp60 in % of dry matter intake
