Question 2

Subacute rumen acidosis:

Answer 2

Increased UKM accumulation and pH 5.5-5.7

Question 3

Acidification of the rumen environment is when:

Answer 3

increased UMK accumulation and pH 5.7-6.0

Question 4

The fiber is fermented in the rumen over …. hours, and % is:

Answer 4

16-25 hours
40-70%

Question 5

Essential polyunsaturated fatty acids most abundantly represented in roughage:

Answer 5

Linoleic (18:2) and linolenic (18:3)

Question 6

Protection of BLK from rumen degradation is mediated by:

Answer 6

Heat treatment at a temperature of 121 C and the addition of xylose

Question 7

Cholecystokinin CCK from the intestinal mucosa:

Answer 7

stimulated pancreatic secretion of enzymes

Question 8

Laboratory diagnostics of inactivated trypsin inhibitor is by:

Answer 8

determination of urease activity in feed

Question 9

The degree of toxicity of lectins varies according to the type of plant:

Answer 9

As the seeds mature, they are released from the bond and their activity increases rapidly

Question 10

BLK for tannin binding are secreted in animals:

Answer 10

in the saliva of animals and by inactivating tannins they reduce fecal losses of NL

Question 11

Progotrin is a rapeseed glucosinolate whose antinutritional activity manifests itself:

Answer 11

direct goitrogenic effect with inhibition of iodine adsorption
hydrolyze something

Question 12

Cyanogenic glycosides in plants act toxic after:

Answer 12

activation to HCN, whicn induces cell hypoxia

Question 13

Saponins in young plants participate in the pathogenesis of:

Answer 13

tympany of Ru

Question 13

On gossypol pigments from cotton seeds:

Answer 13

the highest sensitivity is found in chicken and poultry

Question 14

Contributing factors take part in the formation of leguminous tympany:

Answer 14

from min calcium and magnesium substances increase the degree of tympany

Question 15

Nitrates in feeds fed to Ru cause a metabolic load:

Answer 15

When the capacity of the microflora to transform nitrates into ammonia is exceeded.
The accumulation of nitrites and their transfer into the blood and formation of metHb.
Acute toxicity with a nitrate content above 2.1 g/kg of DM is manifested by cyanosis.

Question 16

Stavelic acid in plants:

Answer 16

Is formed by the oxidation of carbohydrates and AMK in plants.
An excess of stavelic acid in the feed reduces the utilization of Ca.

Question 17

The enzyme lipoxygenase acts as an anti-vitamin A in feed:

Answer 17

With a little drying in the sun, up to 80% of carotenes in hay are destroyed by photooxidation

In the coumarol chimney due to mold and MO, causes bleeding

Question 19

Sporidezmin:

Answer 19

Causes acute inflammation of the bile duct in the liver, which causes obstruction
