Ellie tackles a big topic in this presentation and her take on dairy farming and climate change is sure to inspire many a discussion.

BOGGED DOWN BY THE DEBATEImage www.metro.co.uk 7. IS IT OR ISNTIT ???Image: www.keepbanderabeautiful.org 8. WELL WE THINK THE WHOLE DEBATE IS JUST A HUGE WASTEOF ENERGYImage: www.pulse80.blogspot.com 9. ITS SO LAST CENTURY Image: www.flickr.com 10. TIME TO MOVE ON Image: www.virtuallyyoursjb.com 11. What we do know is less than 7%of Australia is suitable for food production Source: www.dfat.gov.au/facts/env_glance Image: www.waste2energynow.com 12. And the farmers producing thisfood are findingthe resources to do so increasingly scarcer&more expensive. 13. So what are Australian dairy farmers doing about this Image : www.eecs.oregonstate.edu 14. LETS FIND OUT WHAT THE SMART COWS ARE DOINGWe are doing what every-one else on the planetshould be doing. We are using less resources and using themsmarter . 15. We started toget our act together a whileback. 16. Okay we need a few facts and figures before we get started Source: www.climatechange.gov.au/en/climate-change/emissions.aspx 17. The scientists say it with picturestoo???www.climatechange.gov.au/en/climate-change/emissions.aspx 18. Where do emissions from grazing industries come from?? Eckard (2008) www.greenhouse.unimelb.edu.au 19. The less land you need for milk production the more land you have to plant trees and we all know howimportant that is!!!!!! 20. MILKING COWSIN A WORLDWHERE Less IS MORE 21. So its easy Milkless cows who give MORE milk 22. Lets expand on this.It does requiresmart farmers too!!! 23. SMART STRATEGIES The rule of 3s 1. Breeding. 2. Feeding. 3. Animal Management. 24. 1. BREEDINGOkay so we select for cows who canturn feed into milkas efficiently aspossible. 25. Feed Conversion Efficiency (FCE) So what is FCE?Simplest way to put it is most cows eat about 20kg DM* per day. So if she can turn 20kgs of feed into: 20 litres of milk - she has an FCE of 1 40litres of milk - she has an FCE of 2So the higher the FCE the more efficient she is*DM = dry matter i.e. feed with water taken out 26. 2. FeedingFeed me the best quality, energy rich feed you can grow & buy.Trust me Im worth it andI am good for theenvironment too. 27. Grow them big and tall By feeding your cows to grow big and tall and enter the milking herd at two years old you can reduce their non productive life as a green house gas emitter.Sounds very efficient indeed!!! Lets look at why? 28. 2 small cows vs. 1 BIG COW So lets look at the maths Just like you and me a cow uses some of the food she eats to turn into energy for maintenance ( i.e. walking, breathing, growing etc) 1 small cow will use 70 to 80 MJ ( Mega Joules*) just for maintenance 1 big cow will use 100 MJ for maintenance * Joule = measurement of energy 29. But wait there is more If 1 small cow only has the capacity to produce 5000 litres per year and the big cow can produce 10000 litres per year that means the big cow uses 60% less energy for maintenance than 2 little cows to produce the same amount of milk. Bit confused ? Have a look at thepictures on the nextpage. 30. 2 SMALL COWS VS. 1 BIG COW60% MORE ENERGY NEEDED for MAINTENANCE toPRODUCE SAME AMOUNT OF MILK1 x 100MJ = 100MJ = 10000 litres 2 x 80MJ = 160MJ = 10000 litres 31. SO BIG IS BEAUTIFUL - FEEDING COWS WELL CAN REDCUE METHANE EMMISIONS BY 30% www.climatechange.gov.au/en/climate-change/emissions.aspx 32. 3. ANIMAL MANAGEMENT Milking 3 x daily increases milk production by up to 25% This means dairy farmers can milk less cows who produce MORE milk on the same amount of land This means less Green House Gas emissions per unit of production 33. Less Green House Gases??? It is well known by breeding cows with high FCE and milking them 3x daily dairy farmers can reduce Green House Gas Emissions by up to 30% WOWNow thats smart!! 34. Lets look at some other on farm lessisMOREstrategies 35. MORESMART STRATEGIES1.Fertiliser Management. 2.Fertiliser Formulation. 3.Pasture and Soil Management. 36. 1. Fertiliser ManagementHow to MakeLess doMORE 37. Its no laughingmatterImage www.usefilm.com 38. Laughing Gas not so funny Nitrous oxide also known as laughing gas or happy gas is a major greenhouse gas and air pollutant. Over a 100 year period, it has 298 times more impact per unit weight than carbon dioxide. Nitrous oxide escapes into the air when nitrogen fertiliser is used. 39. Fertiliser the aim of thegame is to keep the nutrients on the pasture and out of the airways and waterways. So its very important to: measure what goes in and what goes out and only apply what you need, where you need it and notwhen rain is going to bucket down.Remember Uncle Steves RuleIf you cant measure it,you cant manage it 40. 2. Fertiliser Formulations Like all things driven by need, fertilisers are being developed with protective coatings to reduce the amount of Nitrous Oxide escaping in the atmosphere.Fertiliser isn'tthe only bad guy.Did you walk to work today? 41. 3. Pasture & Soil Management The key is to grow as, much pasture as you can and this allows a high stocking rate i.e. more cows/ha. One of the greatest on-farm challenges is the inefficiencies from wasting grass a high stocking rate utilises the grass when it is available. Using water and nutrient efficient grasses means less fertiliser use and more pasture grown on the moisture shoulders. Grow drought tolerant species with potential for rapid recovery after drought. 42. FOOD MILES ???? The dairy industry only uses grains and by-products not fit for human consumption. And yes the grain truck may travel 300km but we are actually minimising GHGE as we are producing milk close to where it is consumed. After all the milk truck leaves the farm everyday but the grain truck only comes every 6-8 weeks. 43. SO HOW CLEVER IS THE DAIRYINDUSTRY?? THE COWS ARE GETTING BIGGER,PRODUCING MORE MILK FROM LESS OF THEM AND THE FOOTSTEPSARE GETTING SMALLER? 44. Cows are part of the solution If there is a problem it is not the cow, but the way we manage the farm system and its carbon cycle. Dairy farmers have the responsibility to be good stewards of the land and livestock for the benefit of the land, the livestock, the community, and themselves. 45. So dontsweat the small stuff.The time is NOW to get SMART 46. CLIMATE CHANGE OR NOT !!! We have more people to feed, & more people to house, 47. TAKE HOME MESSAGEFollow the cowsdo MOREwith Less 48.
