Dairy Farming Dairy Farming Presentation Transcript

  • An example of livestock farming DAIRY FARMING
    • From March-October (Depending on weather) the cows graze( eat grass) outdoors in the fields
  • Each cow has a “Passport” to identify it when it is being……..
    • Sold
    • Moved
    • Killed
    • Many Irish cows are a breed called friesan –they are black and white in colour
    • They need to eat large amounts of high quality grass to produce milk….
    • One cow can produce 45 litres of milk each day…..WOW !
  • During winter the cows are kept indoors where they are fed silage (green grass stored under plastic)
  • This is what silage looks like up close
  • A machine places the silage mixed with grain in front of the cows
  • Therefore they cannot walk on their food or dirty it
    • Dairy cows have to be milked twice a day-365 days of the year. – a lot of work1!
    • The milking times have to be the same each day- otherwise the cows will get sick
    This is very labour intensive Here the cows are being brought in for milking
  • The building where the cows are milked is called The milking parlour
    • The farmer records the amount of milk given by each cow so he can keep very accurate accounts
    • The cows stand in cubicles in the milking parlour. Cows are creatures of habit so they tend to stand in the same cubicle for each milking
    • Everywhere must be very clean as milk is a food
    • A milking machine is used by the farmer to milk the cows
    • The cows spins or udder is cleaned by the farmer before placing the machine on each cow
    • The milking machine sends out a pulse which takes the milk from the cow in 4-5 minutes
    • While the cows are being milked a machine gives each of them a feed of highly concentrated meal
    • This keeps them happy and quiet (a reward for the milk)
    • The food also contains nutrients and minerals to keep them healthy a
    • The milk is pumped along tubes to a stainless steel tank for storage
  • In the stainless steel tank
    • The milk is stored until it is collected
    The hot milk is cooled immediately
    • To keep it fresh
    • To prevent the growth of bacteria and germs
  • Stainless steel is used as
    • It will not rust
    • It is easily cleaned
    • It is necessary by law to use this material when producing food
  • All the milk records are stored by the farmer on computer
  • Every 3-4 days the creamery collects the milk by stainless steel bulk tanker
  • In the creamery the milk is
    • Tested
    • Pasteurized
    • Bottled etc.
  • Bottled milk is produced quickly by machine
  • Which in turn is delivered quickly to shops and houses. Remember milk is a highly perishable product
    • It must be delivered quickly
    • It must be kept cool
  • Why is milk a valuable food for humans?
  • Milk is used in……….
