success.
Mr. Jacob demonstrated that $192 per acre a year can be realised from
pigs reared almost wholly on lucerne, for half an acre suffices for the
sustenance of a brood sow and her progeny of about 20 per annum till
they are fit for market. Well-bred animals pay best, especially in the
case of the sire, for which a Yorkshire is recommended. Mr. Jacob is
prepared to submit his books and returns to those interested, as he did
to the writer.... It has to be observed that pig raising does not
require either the capital or experience demanded in the case of sheep."

These facts relate in a general way to the industry as it is possible to
be carried on in all parts of the Commonwealth. A dairy man or mixed
farmer finds that the carrying on of his work at a maximum of profit
involves the growth of a number of different crops with which to
supplement the rations of his dairy herd. Peas, barley, wheat, maize,
pumpkins, carrots, mangolds, lucerne, rape, and other crops are more or
less used for a succession. Each one of these is of special value from
the pig-raiser's standpoint. Both peas and barley have a high value for
fattening purposes, and some of the successful breeders maintain that
the addition of wheat contributes largely towards rapid development.
Similarly the root crops play an important part in the general rations,
whereas lucerne and rape make an admirable pasture for the running of
stores and breeding sows. General experience has shown that when pigs
which are being fattened for market have the run of a good pasture of
these crops they do better and fatten on much less food. Consequently
with some one or another or several of these crops to supplement the
skim milk provided by the dairying operations, no more favourable
conditions could well exist for the development of this adjunct to the
dairying industry.

With suitable root and pasture crops there is no reason why pig raising
should remain merely as an offshoot of dairying and farming operations.
It is sufficiently remunerative even when all food has to be purchased
on the open market to justify attention being devoted to raising alone.
But such circumstances do not enter into the operation of the industry
as managed in Australia. The close proximity of separating factories
would in many districts make it possible for a breeder to entirely
ignore the dairying side of the question. From these sources such
supplies of skim milk as were considered an advisabl
