Past Question-Slovak 2023

Question 1

Enzootic ataxia manifests itself:

Answer 1

• In areas with insufficient copper as a result
• High emissions of sulfur and molybdenum
• Due to degenerative changes in the white matter, the lamb has partially or completely paralyzed hind limbs

Question 2

The adverse effect of increasing nitrogen containing substance in the feed ration on fertility manifests itself:

Answer 2

• A decrease in progesterone concentration
  (By reducing LH secretion)

Question 3

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

Answer 3

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

Question 4

The digestibility of the organic matter of the feed mixture for pigs is directly related to the content and chemical nature of the fibre in the feed. This relationship is expressed by Axelson’s equation, where an increase in fiber in dry matter KD by 1% leads to a decrease in the digestibility of organic matter (OD) by:

Answer 4

• 1.68%

Question 5

Admission of heifers is carried out:

Answer 5

• At the age of 14-16 months with weight of 400-450 kg, fitness score 3.0-3.25

Question 6

In nutritional stress the digestive system has an important position. For development of nutritional/digestive/reproductive(?) disorders following occurs:

Answer 6

• Malfunction/disturbance/impairment of the nutritional and protective function of the digestive tract

Question 7

In the pathogenesis of grazing tetany the following are applied:

Answer 7

• High concentration of carbohydrates together with lower NL and fat in the KD, causing a decrease MG absorption from the rumen

Question 8

The source for the synthesis of short- and medium- chain MK in milk fat are:

Answer 8

• Acetic acid after fermentation of structural carbohydrates
• B-hydroxybutyric acid

Question 9

Anionic salts - are applied to dairy cows in the phase of preparation for childbirth with the aim of:

Answer 9

• Specific action in the adaption of the rumen metabolism of dairy cows
• Correction of metabolic alkalosis with a high presence of potassium and sodium in KD
• Increases the sensitivity of bone tissue for the release of Ca from bones to maintain normocalcemia after calving

Question 10

The feeding regime of sows during pregnancy should ensure an average gain:

Answer 10

• A total gain of 45-50 kg, of which body weight 25-30 kg and the weight of the placenta and fetuses represent 20 kg gain

Question 11

Causes increased urea in milk:

Answer 11

• Low representation of non-structural carbohydrates (sugar, starch, pectin)
  (Unbalanced protein intake of the ration(high proportion of NL, BDB, low proportion of BNB))

Question 12

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

Answer 12

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

Question 13

Nutritional reasons for the decrease in fat content in milk (confirmed by TMR analysis):

Answer 13

• Increased proportion of fat (incomplete biohydrogenation of fatty acids)

Question 14

Zinc in relation to reproduction manifests itself:

Answer 14

(Indirect effect through the pituitary gland to influence gonadotropin hormones)

Question 15

Prenatal development and growth of fetal skeletal muscles (myogenesis) is determined:

Answer 15

(Availability of nutrients and control of growth factors during the differentiation of the number of fetal muscle fibers)
(Availability of nutrients for increasing the size (hypertrophy) of fetal muscle fibers)

Question 16

What are the characteristics of ewes nutrition in the first 30 days after admission (mating?):

Answer 16

• Severe malnutrition or high level of nutrition results in poor embryo survival

Question 17

Increased fat content in milk at the postpartum phase is found in:

Answer 17

• In obese dairy cows with the increased lipomobilization

Question 18

In case of nutrition-related disorders of the GIT, sheep suffer from:

Answer 18

• Less often rumen function disorders (acidosis, alkalosis) with more frequent occurrence of intestinal diseases (Clostridia/Clostridium)

Question 19

Why is the method of fecal digestibility of amino acids referred to as “apparent digestibility”:

Answer 19

• Microbial proteins affected by colonic fermentation are also present in feces
• Endogenous amino acids from secreted secretions and the epithelium of the digestive tract are also represented in feces

Question 20

What kind of substance you need to increase on the 90th day for pigs:

Answer 20

• by adding fat (and fiber)

Question 21

What is the characteristic of myodystrophy in lambs:

Answer 21

• Deficient supply of natural antioxidants (vitamin E and selenium) in to the ratio of highly pregnant and lactating sheep
• Limited placental transfer of vitamin E from mother to fetus

Question 22

The most numerous Ig group in colostrum is represented by the class group:

Answer 22

• IgG

Question 23

Cause of pregnancy toxemia in ewes:

Answer 23

• Incorrect/improper phase nutrition of ewes accompanied by excessive feeding in the first phase of pregnancy
• Obesity of ewes, which show lower feed intake in the last weeks of pregnancy in more fertile animals

Question 24

Low fat syndrome:

Answer 24

• Manifests itself with a high content of polyunsaturated fatty acids in the feed ration, which at low pH affects the biohydrogenation of fatty acids
• The content of trans-conjugated linolenic acid (CLA - C18:2 trans- 10-cis-12) synthesized in the rumen increases as a result of incomplete biohydrogenation when the pH drops

Question 25

Luteinizing hormone (LH) produced by the pituitary gland is necessary for the manifestation of ovulation and for the development and preservation of the corpus luteum

Answer 25

TRUE

Question 26

Prostaglandin is produced in the placenta before birth and in the uterus after birth, it initiates the regression of the functional corpus luteum as well as the corpus luteum formed after ovulation during unsuccessful pregnancy

Answer 26

TRUE
