Dairies • A single dairy cow can consume from 25 to 50 gallons of water per day. • Peroxide and Chlorine are commonly injected. pH adjustment is not widely practiced. • There is a strong correlation between water consumption and milk yield
4 Performance Goals • Higher volume of milk produced • Increase fat content in milk • Low somatic cell count • Increased breeding efficiency
Dairy Cows • Somatic cell count (SCC) should be <100,000 cells per ml. Those greater than 300,000 indicate a cow with considerable amount of pathogens. • Somatic cell count is an indicator of milk quality. High numbers indicate high white blood cell counts responding to pathogenic bacteria.
Fat content and Volume • Fat content in milk. The higher the better. Average percentage ranges from 3.6% (Holsteins) up to 5.2% for Jersey cows. • Dairy cows produce from 5 to 8 gallons of milk per day. Output is measured in pounds so that is up to 70 lbs. per day or about 13 tons per year.
Water Storage • Pressure Tank
The use of a non-pressurized intermediate water storage reservoir provides many advantages in the dairy water system: • Supply ample water storage capacity at a low cost to meet daily water volume needs and peak flow rates. • Allow supply from multiple water sources. • Can serve as source for pressurized and non-pressurized uses. • Provide reception point for emergency water supply. • Water source for fire protection. SANITIZER INJECTION PUMPS: commonly used to inject sanitizers into water lines to drop hoses, back-flush units and cow sprinklers
water consumption is comprised of the following end useswashing, cooling and drinking • Potable water for direct consumption by dairy animals • Cleaning water for CIP washing of parlor and milking system equipment. • Washdown water for cleaning of milking parlor surfaces and general sanitation. • Partial cooling (pre-cooling) of milk with well water (heat exchangers). • Water supply to water ring vacuum pumps (claw attached to teats). • Wash pen water use to clean cows prior to entering the milking parlor. • Evaporative cooling sprays [misting] for the dairy cow to reduce heat stress during hot weather and increase cow comfort. • Flush water for manure removal in confinement areas, holding area and milking parlor. • Fire protection
Terminology • SANITIZER INJECTION PUMPS - commonly used to inject sanitizers into water lines to drop hoses, back-flush units and cow sprinklers. • Most chemical pumps are quoted in oz./ min.
