29
Q

Wendee Analysis, the part that does not contain N?

A

Proximate chemical analysis; estimation value for a material for feeding purpose without feeding trial, based on the separation of feed components.

30
Q

What is the effect of induced mutation?

A

There is an increase in essential amino acid production.

31
Q

How should the requirements be saturated during the first lactation of Dairy Cow?

A

The requirements should be increased by 20%

32
Q

Should one calculate with the excretion content in the urine?

What is the most important factor for micro-organisms reproduction in the rumen?

A

Moisture

43
Q

What is metabiosis?

A

Relationship between 2 species, where one is depending on the products of the other. (commensalism)
