Water Flashcards
what percent of milk is water?
85-87%
What are some things that result in death related to water
High TDS (total dissolved solids) –> Sulfates and nitrates.
What increases TDS?
Drought, extreme heat
What is a universal solvent?
Water
What results in the complete oxidation of glucose?
Glycolysis and TCA cycle
When a peptide bond is formed, what is the byproduct?
Water
What are ways to dissipate heat?
Water play a critical role
Heat loss: Sweat/evaporation, radiation, conduction, covection. (not asked)
Sweating, hyperventillation. Find shade, drink lots of water. Slow metabolism.
What is specific heat capacity?
The amount of E it takes to heat 1 cal of water by 1 degree.
What is the role of thermal conductivity?
Allows water to transport heat efficiently from deep body tissues to surface.
What is the importance of the high latent heat of vaporization?
58 cal of heat to convert 1g of water from liquid to vapour.
Panting, and sweating are efficient ways to lose heat.
An increase in feed intake should result in increase/decrease in water intake?
An increase in feed intake should result in an increase in water intake?
Which is more adapted for hotter climate Bas Indicus & Bos Taurus?
Bos Indicus- Brahma. Hotter climate, more adapted to heat. More sweat glands.
Sympoms of water deprivation?
Reduced feed intake, increase heart rate, increased body temp, increased respiration, lack of muscle coordination. Sunked eyes, shrivelled skin. death.
water quality
features of good quality water
- Clear and colorless
- Low total solids
- No disease organisms or pesticides
- No undesirable flavour or odor
Which physical property of water allows large changes in heat production due to chemical reactions taking place in the body’s cells with little alteration in body temperature?
a) high thermal conductivity
b) water is a universal solvent
c) high latent heat of vaporization
d) high specific heat capacity
d) high specific heat capacity
Which physical property of water allows the dissipation of large amount of heat from the body’s surface, thus playing a major role in regulation of body temp?
a) water is a universal solvent
b) High latent heat of vaporization
c) High thermal heat of vaporization
d) High specific heat capacity
Which physical property of water allows the dissipation of large amount of heat from the body’s surface, thus playing a major role in regulation of body temp?
C) High thermal conductivity
The order of importance, list 3 sources of water for animals.
Free water
Water from feed
Metabolic water
LIST 2 dietary factors that will affect water intake in animals. No additional discussion
Increase in DM intake. Increase in dietary protein.
In ONE sentence, what happens to feed intake in animals when water intake is restricted and why does it happen?
Feed intake will decrease when water intake decreases because water is critical in several roles of digestion and as a universal solvent for absorption of nutrients.
in ONE sentence, what happens to water intake in animals with high ambient temperatures and why does it happen?
Water intake increases with high ambient temperature becasue there is more evaporative loss from panting and sweating so that animal will try to compensate by drinking more water.
