    Study Notes

    Water Supply and Quality

    • Water is crucial for animal health and production.
    • Evaporative losses account for 55% of water loss.
    • Urine accounts for 10% of water loss.
    • Feces account for 12% of water loss.
    • Milk accounts for 24% of water loss.
    • Younger animals have lower water requirements compared to older ones.
    • Water loss linked to adipose tissue.

    Water Sources

    • Drinking water sources include surface water, wells, and springs.
    • Concerns about surface water quality, its possible contamination and non-sustainable nature.
    • Municipal water supplies are a viable alternative.
    • Water is obtained through feed and metabolic processes.
    • Crucial to determine the source of water to understand its qualities better.

    Water Intake

    • Dry matter intake impacts water intake.
    • Moisture content of feed increases water intake.
    • Salt consumption influences water intake.
    • Environmental temperature affects water intake.
    • Production levels also impact demands for water.
    • Water quality directly correlates to how much animals drink.
    • Ideal body temperature for animals is 101.5 degrees Fahrenheit.
    • Temperature of water and environmental factors both play a role in how animals consume water.

    Quantity of Water Intake

    • Different animal species have varying water needs based on factors like size, activity level, and physiological state.
    • Water intake varies significantly based on the temperature, 40°F and 80°F are considered in the table in terms of quantity.
    • Water intake of animals is dependent on breed, body mass, activity levels and pregnancy or lactation stage.

    Water Quality

    • Mineral concentration levels, such as sulfates, sulfate-sulfur, copper, selenium, calcium, or magnesium, in water can impact animal health.
    • The concentration of different minerals can vary widely, depending on the source.
    • High sulfate levels negatively influence water intake in animals.
    • Determining the presence of contaminants, like bacteria, is essential for assessing water quality.
    • The appropriate levels of minerals and contamination levels are key factors to examine.

    Total Dissolved Solids (TDS)

    • TDS levels in water can affect animal health.
    • Safe levels of TDS are below 1,000 mg/L.
    • Higher levels of TDS can cause diarrhea and reduced water intake.

    Bacterial Contamination

    • Coliform bacteria levels need to be monitored in water supplies.
    • Other enteric organisms, like protozoa and Salmonella, can also contaminate water.
    • Excessive bacteria in water can pose significant health risks for animals.

    Water Contamination

    • Surface water sources (wells and springs) should be considered for their potential contamination based on their proximity to other sources. The risk of contamination should be assessed.
    • Careful selection and management of water sources are crucial. Maintaining a controlled environment for animals drinking water is essential.

    Signs of Inadequate Water Intake

    • Firm feces is one of the noticeable indicators of inadequate water consumption.
    • Low urine output highlights reduced water intake.
    • Signs of dehydration, like systemic issues and elevated packed cell.
    • Reduced performance suggests inadequate water intake.

    Case Study

    • A local dairy farm struggled with high sulfate levels in its water.
    • Water intake reduced due to high levels of sulfates.
    • Current water treatment methods did not sufficiently address the issue.
    • Reverse osmosis was deemed too costly. Strategies included measurement of water intake, discovery of alternative water sources, investigation of water treatment options, and examination of mineral intake. Monitoring dietary minerals and administration of supplemental minerals where necessary.
