What is the most significant property of water mentioned in the text?
Being less dense as a solid than as a liquid
Why is water considered the 'universal solvent'?
Ability to dissolve a wide range of chemicals
What is the percentage range of water's composition in any living cell?
50 – 80%
How does water play a vital role in the regulation of body temperature?
Through its dipolar nature
What is the key significance of water for efficient digestion and metabolism?
Serving as an essential solvent
What is the average daily water consumption for Milking Cow + service?
130 L
Which animal has an average daily water consumption of 3–5L?
(90 % production) Layers (100 birds)
Why must water quality intended for animals contain no toxic substances?
To promote health and well-being of the animals
What is the primary function of water in animal production operations?
Cleaning purposes and disposal of waste
What makes water a vitally important substance in living cells?
Polar parts binding to negative and positive ions
What results in serious physical disorders according to the text?
Losing water
What is the percentage range of water's composition in the body weight depending on age, sex, and species of the animal?
75 – 90 %
What is the molecular structure of water and how does it contribute to its properties?
The molecular structure of water is H2O, with two atoms of hydrogen attached to one atom of oxygen. The O end of the molecule has a negative charge, and the H end has a positive charge, creating a dipole.
Explain the composition of chemically pure water by volume.
Chemically pure water is composed of Hydrogen and Oxygen in a proportion of 2:1 parts by volume, i.e., H2O.
Why does chemically pure water not exist outside the laboratory?
Chemically pure water does not exist outside the laboratory due to its solvent properties, which lead to the absorption of impurities and contaminants from the surrounding environment.
What is the significance of the dipole nature of the water molecule?
The dipole nature of the water molecule, with the O end having a negative charge and the H end having a positive charge, is significant for understanding its unique properties, such as its ability to form hydrogen bonds and act as a solvent.
What causes the solid form of water to be less dense than its liquid form?
The arrangement of water molecules in a crystalline lattice with fixed distances in ice results in less extensive bonding and tighter packing in liquid water.
What is the percentage range of water's composition in any living cell?
50 - 80%
What is the key significance of water for efficient digestion, metabolism, and fecal elimination?
Water is the key for efficient digestion, metabolism, and fecal elimination.
What is the average daily water consumption for Broilers (6 weeks)?
15 L (100 birds)
What is the primary function of water in animal production operations?
Water intended for animals is used for drinking, cleaning, transportation, disposal of wastes, and maintenance of cleanliness for animals and buildings.
Why is water considered the 'universal solvent'?
Water is considered the 'universal solvent' because of its ability to dissolve a wide range of chemicals.
What is the molecular structure of water?
Dipolar
What makes water a vitally important substance in living cells?
Water constitutes a large portion of any living cell and serves as an essential solvent, playing a vital role in various bodily functions.
What results in serious physical disorders according to the text?
The loss of 1/10 of the body's water results in serious physical disorders.
What is the percentage range of water's composition in the body weight depending on age, sex, and species of the animal?
55 - 75%
Why must water quality intended for animals contain no toxic substances?
Water quality must promote the health and wellbeing of the animals, containing no toxic substances in amounts that are harmful.
