Water footprint of broiler meat production in Sri Lanka: An analysis
- 1. Atapattu NSBM Department of Animal Science, Faculty of Agriculture, university of Ruhuna, Mapalana, Kamburupitiya
- 2. Introduction Future of human civilization will centre around water Water footprint(WF) = total water used in production cycle/unit of production Issues related to WF are complex
- 3. For example Product Country WF m3/ton Boneless beef, frozen Brazil 30888 Ireland 17854 World average 24838 Swine (live) Australia 8124 France 1936 World average 2819 Poultry New Zealand 4179 France 795 World average 1498 Maize Sri Lanka 3202 Rice Sri Lanka 3168 Chapagain and Hoekstra, 2003
- 4. WF content of a product is an indirect measure of its eco-friendliness An analysis of WF can be used to identify means of reducing WF content WF content of poultry meat in Sri Lanka 9885m3/ton (assuming 75% dressing %) Chapagain and Hoekstra, 2003
- 5. Is this value correct/realistic ? Methodology problems Some components have not considered Changes in production efficiency
- 6. Objective To determine the WF of broiler meat production of Sri Lanka, under the current production condition and parameters and, to explore the possible avenues to reduce the WF of broiler meat production.
- 7. Methodology WF = Feed water + Drinking water + Servicing water Feed water = feed water + Feed mixing/preparation water Drinking water = Feed water X 2.5 Servicing water = labour water + litter water + other
- 8. Calculation of feed water Step Assumption Value Meat weight 1000 Required live weight Dressing % =75 1333 Number of birds to be slaughtered Live weight at slaughter =2.2 606 Number of day old birds Mortality =5% 636 Initial live weight of the flock Day old chick weight 0.045 27 Live weight gain 1306 Total feed requirement Feed/gain = 2 2612 From day 0-21 871 From day 21-42 1741
- 9. Feed Ingredient Consumption Water (feed) Feed % WF PF WFxPF Starter Finisher Starter Finisher Total Maize meal 42 3203 1 3203 366 731 1171 2342 3514 Rice bran 20 3168 0.1 317 174 348 55 110 165 Soybean meal 27 4851 0.85 4123 235 470 969 1939 2908 Palm oil 5 552 0.19 105 19 87 2 9 11 Fish meal 3.2 7130.97 6061 28 56 169 338 507 2367 4738 7105 7104 Feed preparation 1.3 Total feed water 7105.0
- 10. The drinking water requirement was considered as 2.5 x total feed intake 6.5 m3/ton The servicing water component was the sum of water cleaning utensils the labourers water WF of litter material unspecified requirements.
- 11. Component M3 % Feed water 7105 94.2 Drinking water 6.2 0.1 Labour 0.42 Litter 434.016 Other 0.42 Total servicing 434.8 5.8 WF 7546 100.0
- 12. Discussion Refined methodology Reflects current production/performance condition
- 13. Even with new components, lower than reported value Critical points to intervene It is the feed % Maize 49 Soybean 40 Though ration had 20% RB RB contributed only 2.3% to WF
- 14. Conclusions WF of broiler meat under SL conditions 7546 M3/Ton Feed is the most influencing component Use of by products reduces WF
