Recipe
Prep time 25 min Cook time 1 hr 25 min Serves 18
Spiced apricot and maple glazed leg of ham
INGREDIENTS
• 1 x 7-8kg ham leg, skin removed • Whole cloves (you’ll need about
50) for studding the ham
Spiced apricot & maple glaze
• 3⁄4 cup apricot jam
• 1⁄4 cup maple syrup
• 3 star anise
• 1 teaspoon ground cinnamon
• 1⁄2 teaspoon allspice
METHOD
1. Preheat oven to 180˚C/160˚C fan- forced.
2. Using a sharp knife, score the ham fat (not the flesh) in a grid pattern at 2cm wide intervals. In- sert a clove into the centre of each square of fat.
3. Wrap the ham hock in foil (this prevents it from burning). Place
the ham on a greased rack in a large baking dish lined with foil. For ease use a large disposable foil roasting dish.
4. To make the glaze, combine all ingredients in a medium saucepan. Bring to the boil, stirring, over me- dium heat. Reduce heat and sim- mer, stirring occasionally, for 8-10 minutes or until slightly thickened. 5. Brush ham two to three times with the glaze to evenly coat the ham fat. Bake for 50 minutes to 1 hour, brush- ing with remaining marinade every 15 minutes, until ham is golden
and caramelised. Arrange star anise (used in the glaze) on the ham in the last 15 minutes of baking.
6. Set aside to cool for 30 minutes. Slice and serve.

Outcomes of the second mycoplasma hyopneumoniae advisory group meeting
MYCOPLASMA hyo- pneumoniae is a lead- ing cause of porcine res- piratory disease complex throughout the Austral- ian pig industry.
Improved control strat- egies have the potential to address the significant economic losses associ- ated with decreased per- formance of the pigs and increased medication use.
An advisory group of Australian experts recent- ly held its second meeting to discuss up-to-date and effective M. hyo control measures for the Austral- ian pork industry.
Sponsored by Boehring- er Ingelheim Animal Health Australia, the group aims to utilise its field and diagnostic ex- pertise to devise M. hyo control strategies that are best suited to the herd health status of the vary- ing husbandry systems of Australia’s pig produc- tion.
Progress report
At the previous meet- ing, the group agreed that lack of data on the effect of different envi- ronmental conditions on the control of respiratory diseases in Australia is a key challenge that must be addressed to improve res- piratory disease control.
It is thought that gilts are the main shedders to their offspring, who in turn infect other parity weaners when they are co-mingled.
We know the severity of the disease in the fin- isher shed is dependent on the number of infected weaners.
As a result, members of the group performed an initial study aimed at de- termining the extent of M. hyo shedding in gilts to their progeny.
Results from this study, presented at the Austral- ian Pig Veterinarians conference in October 2018, generated valuable discussions and further questions.
These will be investi- gated in further research involving continued col- lection of data from dif- ferent farms, across dif- ferent parities and with longitudinal sampling of pigs at various/age stages of growth.
Additional projects aimed at better under- standing the control of M. hyo in Australia are also under way to determine the best way to acclima- tise replacement breed- ers to ensure they have stopped shedding M. hyo at farrowing.
Two of the M. hyo advi- sory group members have also been working on a project supported by the Victorian Pig Compensa- tion Fund to develop a pig vaccine against Pasteur- ella multocida.
Pasteurella multocida is a common cause of death in finishers and is usually a coinfection with M. hyo.
M. hyo suppresses the normal defence mechan- ism of the lungs, allow- ing a secondary bacterial infection with pasteurella multocida to occur. What’s next?
The group will meet again regularly in 2019 to further progress their goal of implementing practical and cost-effective solu- tions, based on collabora- tive scientific knowledge
and expertise, to develop and promote best practice M. hyo infection control strategies for Australian pig herds.
