In the nutritional prevention of hypocalcemia and parturition paresis in dairy cows, the following applies:
a. reduction of daily calcium intake at the level of 60-80 g/day and K value above 30 g/day

c. reduction of daily calcium intake at the level of 60-80 g/day and K value to 15 g/day
A low content of starch in the feed ration of dairy cows shows:
a. decrease in milk production, reduction in protein content, increase in urea level in milk
b. by increasing feed intake, increasing protein content, and decreasing the level of urea in milk
c. reduced milk production and a decrease in the level of urea in milk
a. decrease in milk production, reduction in protein content, increase in urea level in milk
Phytic acid in plant seeds binds with phosphorus to form phytates, which:
a. are hydrolysed by the enzyme phytase in the small intestine of mono gastric animals
b. are hydrolysed by microbial phytase in the rumen and large intestine of animals
c. act as an inhibitor of the aconitase enzyme in the Krebs cycle
b. are hydrolysed by microbial phytase in the rumen and large intestine of animals
The role of protozoa in inhibiting as well as stimulating the course of rumen acidosis:
a. absorption of starch particles in protozoal cells reduces bacterial fermentation of starch - formation of VFA and lactic acid
b. decline in pH below 5.7 causes defaunation and the release of intracellular amylase increases the breakdown of starch and the growth of lactobacilli for the production of lactic acid
c. the addition of fat due to free fatty acids reduces the number of protozoa
a. absorption of starch particles in protozoal cells reduces bacterial fermentation of starch - formation of VFA and lactic acid
b. decline in pH below 5.7 causes defaunation and the release of intracellular amylase increases the breakdown of starch and the growth of lactobacilli for the production of lactic acid
Nutritional causes of developmental orthopaedic diseases in horses
Increase in feed of: starch, protein, phosphorus
Decrease in feed: calcium, copper, zinc, manganese
= Inbalanced ratio of calcium and phosphorus
The fact that they eat a lot of carbs, protein & fat increased their weight and put pressure on bone so the bone is not developed correctly
It affects hormone regulation which limits cartilage development
Lead to issues with growth development because joint, bones and tendons are not well developed
Grain intake for optimal GIT function and prevention of colic diseases in horses is:
a. maximum one-time dose of 0.4-0.5 kg/ 100 kg of body weight
b. maximum daily dose of 0.4-0.5 kg/ 100 kg of body weight
c. dependant on treatment in the form of meal of small grains or whole grain corn
a. maximum one-time dose of 0.4-0.5 kg/ 100 kg of body weight
The nutritional causes of the formation of oxalate urinary stones in dogs and cats are conditioned by:
a. acidification of urine and increased intake of ascorbic acid - as a precursor for the formation of oxalates
b. increased concentration of Mg, P and NH3 in urine and alkalisation of urine
c. urine alkalisation in case of infection with urease-producing microorganisms
a. acidification of urine and increased intake of ascorbic acid - as a precursor for the formation of oxalates
Regulation of the buffering capacity of the rumen is ensured by:
a. supporting the absorption of dissociated VFAs - in exchange for bicarbonate
b. supporting the absorption of non-dissociated H-VFA in exchange for bicarbonate
c. supporting chewing and production of bicarbonate and phosphate buffer
b. supporting the absorption of non-dissociated H-VFA in exchange for bicarbonate
c. supporting chewing and production of bicarbonate and phosphate buffer
Clinical nutrition for idiopathic hepatic lipidosis of cats is applied in the form of:
a. a balanced ratio of proteins and fats with a high saturation of vitamin. E in diet
b. forced feeding - nasogastric or gastrostomy tube
c. application of energetic substances and glucoplastic substances in diet
b. forced feeding - nasogastric or gastrostomy tube
Microbial synthesis of fatty acids in the rumen is:
a. synthesis of conjugated linoleic acid
b. synthesis of fatty acids C18:0 and C16:0 in a ratio of 2:1
c. de novo synthesis from carbohydrate sources
b. synthesis of fatty acids C18:0 and C16:0 in a ratio of 2:1
c. de novo synthesis from carbohydrate sources
In case of nutrition related GIT disorders, sheep suffer from:
a. less often rumen function disorders (acidosis, alkalosis) with more frequent occurrence of intestinal diseases (Clostridia)
b. less often rumen function disorders (acidosis, alkalosis) with less frequent occurrence of intestinal diseases (Clostridia)
c. more often rumen function disorders (acidosis, alkalosis) with more frequent occurrence of intestinal diseases (Clostridia)
a. less often rumen function disorders (acidosis, alkalosis) with more frequent occurrence of intestinal diseases (Clostridia)
In the prevention of GIT disorders in weaning piglets, antimicrobial factors added to feed mixtures are used:
a. chemical - copper sulphate, zinc oxide
b. additions of organic acids (formic propionic, citric)
c. additions of feed antibiotics
a. chemical - copper sulphate, zinc oxide
b. additions of organic acids (formic propionic, citric)
Anionic salts- are applied to dairy cows in the phase before calving (3 weeks) with the aim of:
a. increase the sensitivity of bone tissue for the release of Ca from the bones to maintain normocalcemia after parturition
b. specific action in the adaptation of the rumen metabolism of dairy cows
c. correction of metabolic alkalosis with a high content of potassium and sodium in feed ration
a. increase the sensitivity of bone tissue for the release of Ca from the bones to maintain normocalcemia after parturition
c. correction of metabolic alkalosis with a high content of potassium and sodium in feed ration
