The Essential Amino Acid Requirements in Horses

What are the essential amino acid (EAA) requirements per unit of energy (EAA/Mcal DE ratio) based on?

a. Exercising horses
b. Lactating mares
c. Pregnant mares
d. Nursing foals

Answer:

The essential amino acid (EAA) requirements per unit of energy (EAA/Mcal DE ratio) for horses are based on exercising horses.

The EAA/Mcal DE ratio is a measure of the relative amount of EAA required per unit of energy, and it can vary depending on the specific needs of the animal and its stage of life. In general, the EAA/Mcal DE ratio is lower for animals that require more energy to maintain their body weight or that are in a growth phase. This is because the energy required for growth and maintenance takes priority over the synthesis of non-essential amino acids, which can be synthesized by the animal's body.

It is possible that exercising horses, lactating mares, pregnant mares, and nursing foals all have different EAA/Mcal DE ratios depending on their specific needs. However, the specific requirements of each of these groups determine the EAA/Mcal DE ratio for any of them.
