Deck 3 Flashcards
Representation of prolamins (storage protein of grain endosperm) is:
a. in dry corn grain 2.5x higher than in wet corn grain b. in dry corn grain 2.5x lower than in
wet corn grain
c. in dry corn grain 1.5 times higher than in wet corn grain
a. in dry corn grain 2.5x higher than in wet corn grain
The requirements for the representation of the physically effective (feNDV) for the concentrated type of KD depend
from:
A. the quality, type and nature of the included bulk feeds
B. the extent and
speed of starch fermentation (type of starch and endosperm structure)
C. share of by-products
A. the quality, type and nature of the included bulk feeds
B. the extent and
speed of starch fermentation (type of starch and endosperm structure)
C. share of by-products
Colic diseases of horses with impaired function of the small intestine are conditioned by:
A. clogging (short cut grass, silage,…)
B. disturbance of fermentation, formation of gases and loss of motility
C. intense fermentation and drop in pH
A. clogging (short cut grass, silage,…)
B. disturbance of fermentation, formation of gases and loss of motility
Carbohydrate sources affecting the amount of milk and the fat content in milk are:
A. the amount of non-fibrous carbohydrates (NVS) formed by the proportion of starch and sugars
B. the amount, digestibility and structure of fibrous carbohydrates
C. the amount
of simple sugars
A. the amount of non-fibrous carbohydrates (NVS) formed by the proportion of starch and sugars
B. the amount, digestibility and structure of fibrous carbohydrates
In breeding practice, very early weaning of lambs is used when the farm specializes in:
A. production of milk for cheese production with separation from the mother until the 3rd day after birth
B. production of broiler lambs with weaning at slaughter in the 5th-7th day. weeks
C. milk
production and cheese production with separation from the mother in the 3rd-4th week after birth
A. production of milk for cheese production with separation from the mother until the 3rd day after birth
The pathogenesis of ketosis in dairy cows takes
place:
A. with a deficiency of glucogenic nutrients – a low level of insulin and high activity of glucagon stimulates B-oxidation of NEMK, which increases ketogenesis with oxaloacetate deficiency
B. in obese dairy cows – high insulin activity and tissue resistance to insulin inhibit B-oxidation and increased synthesis of malonyl CoA enhances ketogenesis
C. with deficiency of glucogenic nutrients – low level of insulin and high activity of glucagon stimulates
formation of acetylCoA, which increases ketogenesis with sufficient oxaloacetate
A. with a deficiency of glucogenic nutrients – a low level of insulin and high activity of glucagon stimulates B-oxidation of NEMK, which increases ketogenesis with oxaloacetate deficiency
Vitamin D toxicosis caused by active vit D derivatives on pasture is manifested by:
a. increased absorption of Ca, hypercalcemia, deposition of Ca in arteries
b. impaired absorption of Ca, hypocalcemia and bone demineralization
c. by disrupting metabolic
regulation with the manifestation of grazing tetany
a. increased absorption of Ca, hypercalcemia, deposition of Ca in arteries
The influence of fermentation activity and pH on changes in microbial colonization of the
rumen:
A. At pH <6.0, Megasphaera elsdenii ferments 60-80% of lactic acid to acetate, propionate,
B. at pH >6.0, multiplication of Streptococcus bovis, which creates acetic acid, formic acid, ethanol
C. at pH < 6.0, multiplication of Streptococcus bovis, which creates vinegar, acid ant and ethanol
A. At pH <6.0, Megasphaera elsdenii ferments 60-80% of lactic acid to acetate, propionate,
B. at pH >6.0, multiplication of Streptococcus bovis, which creates acetic acid, formic acid, ethanol
Regulation of the rate of absorption of UMK through the wall of the rumen into the blood is mediated by:
a. active absorption of dissociated UMK in exchange for HCO3-
b. active
absorption of undissociated UMK in exchange for HPO4-2
c. passive absorption of
dissociated UMK
a. active absorption of dissociated UMK in exchange for HCO3-
The CKT fat acidity number expresses:
a. the amount of free fatty acids determined as the mass of KOH (in mg) needed to —— neutralization of acids in 1g of fat
b. the amount of free fatty acids determined as the mass of NaOH (in mg) needed ——- to neutralize the acids in 1g of fat
c. the amount of fat released after hydrolysis
a. the amount of free fatty acids determined as the mass of KOH (in mg) needed to —— neutralization of acids in 1g of fat
The degree of toxicity of lectins varies according to the type of plant:
a. as the seeds mature, they are released from binding and their activity increases rapidly
b. in
immature seeds, lectins are bound to an inhibitor - high activity of lectins
c. the activity of lectins is low
in mature seeds
a. as the seeds mature, they are released from binding and their activity increases rapidly
