Question

Where are degradable proteins broken down?

(a) Reticulum

(b) Abomasum

(c) Omasum

(d) Rumen

This question was addressed to me in unit test.

Question is from Diseases and Deficiency topic in chapter Cow Health of Dairy Engineering

Answer 1

Correct answer is (d) Rumen

To explain I would say: Degradable Protein (RDP) is the fraction of Crude Protein (CP) consumed which is broken down by rumen microbes. A much simpler bench top was proposed in which feed samples are incubated with a mixture of protein- degrading enzymes extracted from the rumen.
