Pig industry overview Why are pigs important? How did the pig industry develop? What pig breeds are involved? How is the industry structured? What are the key performance indicators? What influences these key performance indicators?
Why are pigs important? Meat – 40% of the global meat consumption Skin and leather products Pharmaceutical products – heart valves Pleasure and company – pet pigs
MEAT Yes… all from one wonderful, magical animal!
Country Millions of pigs China460 (62% global pork eaten in China) India17 Indonesia6 Korea North3 Korea South9 Malaysia2 Myanmar4 New Zealand0.4 Philippines12 Taiwan7 Thailand7 Vietnam22
Our impact on the planet – The Carbon Footprint of Pork Food kg CO 2 -e/kg (20 years)kg CO 2 -e/kg (100 years) Beef 111.155.5 Sheep meat and wool 96.332.7 Pig meat 10.53.5 Rice 2.40.74 Poultry 1.30.38 Wheat 0.350.32
The Artiodactyla – even toes Pigs Also cattle and camels And even related to the whales - Ambulocetus
How did the pig industry develop Small numbers of pigs per farmer Side business to other farming = grain production and/or dairy (to use by-products)
Feeding pigs in WA Barley and Wheat = main grains (energy) Lupins and canola = protein. Swill feeding is illegal: – Meat and bone meal does not count (heat treated) – Definition is different between states of Australia
StatePercentage NSW30 Queensland21 Victoria19 South Australia17 Western Australia12 Where is the grain? Where are the pigs?
Western Australia 26,000 sows. Major foreign market Singapore Sow Herd WA 0 10000 20000 30000 40000 50000 1992200120042007 Year Sows 0 200 400 600 800 1000 Producers Sows Producers
How is the industry structured? Multiplication farms 6000 sows Commercial farms 90,000 sows Males (boars) Females (gilts) Nucleus farm 500 sows
How is the farm designed Breeding Gestation 115 days Farrowing Weaning Grow/finish Slaughter Selection Nucleus farm Basic Pig Life Cycle
Lets walk the farm… Breeder shed Gestation shed Farrowing shed Weaner shed Grower/Finisher shed And speak the jargon and key performance indicators as we go…
Breeder shed Boar – entire male Barrow/Castrate – surgically castrated Gilt – birth to first litter female Sow – breeding female has had a litter
Breeder / Gestation shed – key performance indicators TargetInterference Wean to re-mate (service) interval 5 days>7 days Sow feed in tonnes / year 1.1>1.2 Farrowing rate87 %<82 % Breeding/service/mating – As implied Wean to service/breeding interval – Number of days between weaning and breeding Repeat/Return – Failure to conceive (18-24 days) Farrowing rate – Number females farrowed/Number females bred Culling – Removal from herd/farm (eg. parity >6)
Gestation shed Parity = Number of farrowings. Gestation = state of pregnancy Dry Sow = period other than lactating
Farrowing shed Litter = group of piglets reared by a sow Piglet/Sucker = piglet still on a sow Farrowing = parturition / giving birth Lactating = producing milk
Farrowing shed – key performance indicators TargetInterference Pigs born alive/sow 10.9<10.4 Pre-weaning mortality 10 %>14% Pre-weaning mortality – % piglet deaths between birth and weaning Pigs sold per sow per year 23<21.5
