The University <strong>of</strong> Western Australia <strong>Sheep</strong> milking research project aims at evaluating <strong>the</strong><br />
dairy potential <strong>of</strong> <strong>the</strong> Awassi and East Friesian sheep and <strong>the</strong>ir crosses with local breeds to<br />
establish which cross has <strong>the</strong> best potential for dairy production.<br />
The lack <strong>of</strong> typical Australian sheep milk products<br />
The second problem faced by <strong>the</strong> Australian sheep milk industry is <strong>the</strong> fact that because<br />
sheep milking is not a tradition in our country, we do not have typical Australian sheep milk<br />
products. The majority <strong>of</strong> manufacturers entering <strong>the</strong> industry were aware <strong>of</strong> <strong>the</strong> importation <strong>of</strong><br />
sheep milk products from overseas for <strong>the</strong> local ethnic communities. Therefore, <strong>the</strong>ir first<br />
attempts concentrated on imitating imported overseas cheeses such as <strong>the</strong> famous Pecorino and<br />
Fetta. However, <strong>the</strong>se cheeses are protected by tariffs and DOC trademarks, or suffer from<br />
serious competition from cheap cow's milk imitations. Moreover, some <strong>of</strong> <strong>the</strong>se cheeses (e.g. <strong>the</strong><br />
Pecorino) require long maturation times involving high storage costs and risk <strong>of</strong> spoilage during<br />
storage.<br />
These cheeses also have very strong flavours and <strong>the</strong>y are imported and consumed within <strong>the</strong><br />
local ethnic communities who are used to <strong>the</strong>ir strong taste. Australian consumers, by contrast,<br />
like milder products (e.g. Colby instead <strong>of</strong> matured Cheddar; Burton, 1990).<br />
In overseas countries where milking sheep is an ancient tradition, most <strong>of</strong> <strong>the</strong> sheep milk<br />
produced is transformed into cheese and some into yogurt (Bencini and Pulina, 1997). It is<br />
probably for this reason that manufacturers entering <strong>the</strong> industry initially produced only cheese<br />
and yogurt. However, novelty products, fresh products, and healthy and low fat products nowadays<br />
also attract consumers.<br />
We believe that a viable sheep milking industry could only be established by developing<br />
typical Australian sheep milk products. These will eventually not only replace some <strong>of</strong> <strong>the</strong><br />
importations, but also will be exported similarly to Australian wines. Our research project aims<br />
at developing new sheep milk dairy products including specialty cheeses, yogurt and ice cream<br />
that should be acceptable to Australian consumers and to investigate potential markets for <strong>the</strong>se<br />
products.<br />
Lambs<br />
The third problem faced by <strong>the</strong> sheep milking industry is that <strong>of</strong> <strong>the</strong> disposal <strong>of</strong> lambs. If<br />
lambs are left with <strong>the</strong>ir mo<strong>the</strong>rs <strong>the</strong> amount <strong>of</strong> milk <strong>the</strong>y drink even with early weaning is such<br />
that <strong>the</strong> whole operation becomes unpr<strong>of</strong>itable. Many farmers have concluded that it is better to<br />
kill <strong>the</strong> male lambs at birth and keep <strong>the</strong> females for replacement, ei<strong>the</strong>r artificially feeding <strong>the</strong>m<br />
or by allowing <strong>the</strong>ir mo<strong>the</strong>rs to wean <strong>the</strong>m. This solution has animal welfare implication and is<br />
disliked by many farmers (T. Dennis, Pers. comm.). Moreover, sheep milking is relatively new<br />
with consumers that are curious and occasionally reluctant to accept even <strong>the</strong> idea <strong>of</strong> milking a<br />
sheep. It is possible that consumers could be turned <strong>of</strong>f by <strong>the</strong> idea that newborn lambs are killed<br />
to produce <strong>the</strong> milk. Some farmers attempted feeding <strong>the</strong> lambs artificially, similarly to what is<br />
done in <strong>the</strong> dairy cattle industry. However, artificial feeding is extremely expensive and labour<br />
intensive. Lambs tend to get sick and die, which increases dramatically <strong>the</strong> cost <strong>of</strong> <strong>the</strong> operation.<br />
Overseas countries that have a tradition for milking sheep also have markets for young milkfed<br />
lambs. For example in Italy, male milk-fed lambs are slaughtered at 4 weeks <strong>of</strong> age and 6-8<br />
kg body weight. It is very common to see a whole lamb carcass sold in butcher shops fetching<br />
prices <strong>of</strong> $25-35/kg. The females to be used for replacement are kept with <strong>the</strong>ir mo<strong>the</strong>rs for
