Dairy Farming

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