    Study Notes

    Molecular Structure of Water

    • Water (H₂O) consists of two hydrogen atoms covalently bonded to one oxygen atom, forming a bent molecular shape.
    • The dipole nature of water is due to the difference in electronegativity between oxygen and hydrogen, creating a partial negative charge at the oxygen end and partial positive charges at the hydrogen ends.

    Composition of Chemically Pure Water

    • Chemically pure water is composed of 88.81% oxygen and 11.19% hydrogen by volume.
    • Chemically pure water is rare outside laboratory settings due to contaminants present in the environment.

    Charge Distribution in a Water Molecule

    • Oxygen carries a partial negative charge, while hydrogen atoms exhibit partial positive charges, contributing to water's unique properties.

    Faculty Affiliation

    • Dr. Mohamed Abdelhamid is affiliated with a faculty that focuses on animal sciences.

    Significant Properties of Water

    • Water’s most significant property is its role as a solvent, allowing it to dissolve more substances than any other liquid, hence termed the 'universal solvent.'
    • Water is critical for metabolic processes, efficiently facilitating digestion and nutrient absorption.

    Water in Living Cells

    • Water composition in living cells typically ranges from 70% to 90%.
    • The composition of water in an animal's body can vary between 50% to 80%, influenced by age, sex, and species.

    Regulation of Body Temperature

    • Water regulates body temperature through homeostasis, utilizing mechanisms like sweating and evaporative cooling.

    Water's Role in Digestion and Metabolism

    • Water is vital for the digestion process as it helps dissolve nutrients and transport them, enabling efficient metabolism and fecal elimination.

    Daily Water Consumption for Animals

    • Milking cows typically require around 25-50 gallons of water daily.
    • Broilers (6 weeks old) usually consume about 1.5-2 liters of water per day.
    • An average daily water consumption of 3-5 liters is noted for certain small animals, like rabbits.

    Water Quality and Safety

    • Water intended for animal consumption must be free from toxic substances to prevent health issues and physical disorders.
    • Poor water quality can lead to serious physical disorders and negatively impact animal health and productivity.

    Importance of Water in Animal Production

    • The primary function of water in animal production is to serve as a crucial component for physiological processes, ensuring optimal health and productivity in livestock.
