Answer 3

• 50g of immunoglobulins per l of colostrum

Question 4

Rumen absorption of Mg by activetransport is reduced by:

Answer 4

• The high NH3 content in the rumen content
• The high content of fat and K content in the feed ration

Question 5

Absorption of Mg from the digestive tract of dairy cows takes place:

Answer 5

• In the region of the rumen and reticulum by active transport through the wall

Question 6

Physiological differences in the digestion of nutrients in sheep compared to dairy cows are manifested:

Answer 6

• Passage of feed through the GIT is faster in sheep with shorter retention of feed in the rumen than in the intestine

Question 7

Polioencephalomalacia manifests itself with a deficiency of:

Answer 7

• Vitamin B1 (thiamine)

Question 8

The persistence of the lactation curve after the peak of lactation represents a decrease in milk in the range:

Answer 8

Question 9

In the nutritional prevention of hypocalcemia and parturition paresis in dairy cows, the following applies:

Answer 9

• Decreasing the daily in take of Ca at the level of 60-80 g/day and the value of K to 15 g/day

Question 10

Nutritional causes of reproductive disorders are:

Answer 10

• Negative impact of atinutritional substances in feed on the reproductive cycle
• Unbalanced supply of energy, the content of fat an proteins, a saturation of mineral substances and vitmins

Question 11

Enzootic ataxia of lambs manifests itself in:

Answer 11

• Copper deficit or increased proportion of sulfur and molybdenum

Question 12

The coagulation activity of abomasum during milk feeding is decisively influenced by:

Answer 12

• The rate of milk coagulation in the abomasum
• The quality of the formed casein precipitate

Question 13

By production of VFAs after fermentation of fibre in the large intestine, pigs obtain:

Answer 13

• Of 25-30% energy for maintenance

Question 14

The method of ileal digestability of amino acids in feed is used for:

Answer 14

• The determination of the difference between the content of received amino acids and the absorption of amino acids

Question 15

Ca homeostasis in animals is regulated by:

Answer 15

• thyroid hormoe calcitonin during the deposition of Ca in bone tissue
• Steroid hormone 1.25-dihydroxycholecalciferol to support absorption from the small itestine
• Parathyroid hormone for the release of Ca from bone tissue

Answer 18

• 10% of the birth weight of calves immediately after calvig

Question 19

Overfeeding of CP with an increase in the level of nH3 in the rumen and urea in the serum manifests itself:

Answer 19

• By increasin the pH in the uterine secreation and has a toxic effect on the egg and sperm after insemination
• By reducing the synthesis ofprogesterone and stimulating the synthesis of PGF2a synthesis

Question 20

The chemical score is applied to evaluation:

Answer 21

• Of the analysed content of individual amino acids in the feed mixture compared to the standardized requirement for pigs

Question 22

The low level of nutrition of ewes during the last six weeks of pregnancy results in:

Answer 22

• The increased lipomobilization and development of pregnant toxemia in ewes

Question 23

In the pathogenesis of grass tetany apply the following:

Answer 23

• A low conncentration of carbohydrates together with high representation of CP and fat in the ration, which causes a decrease in the absorption og Mg from the rumen

Question 24

In the pathogenesis of pregnancy toxemia in ewes, the following applies:

Answer 24

• Malfunction of carbohydrate nutrition (high proportion of fibre and deficit of starch) reduces the production of VFA and propionic acid with lipomobilization
