WATER PLAYS A KEY ROLE IN MILK PRODUCTION, CONTROL OF BODY
TEMPERATURE AND MANY OTHER BODY FUNCTIONS IN DAIRY CATTLE
88% of milk is made up of water. Inadequate water supply or poor quality implies a production loss and
increases the level of stress in the herd.
Today, the total water requirements for cattle is 11.9% higher than it was 10 years ago, because
productivity has increased and cattle are genetically different.
Some researches have estimated a need of about 4-5 liters of water per liter of milk produced and
there are changes as lactation progresses: in the early stages it is greater (up to 133 liters per day per
cow), in the final stages it is lower (up to 106 liters per day per cow), while in dry period it is less (up to
76 liters per day per cow).
To ensure the right water supply Water MUST be of excellent quality
and its temperature should be between 10 and 20 °C.
REQUIREMENTS OF WATER THOUGHTS:
A sufficient number of water Troughs are required in order to ensure for each animal 10 cm
of drinking water place per head.
10-15% of the herd must be able to get water at the same time. Each drinker must be
provided with 1,2 metr minimum length to allow at least 20 animals to drink.
Water troughs should be 30/35 cm deep, with a flow rate of at least 10 l/min.
The water troughs must be cleaned, positioned in the shade and in places easily accessible
