Pig Husbandry Research In Western Australia, N W. Godfrey

Journal of the Department of Agriculture, Western Australia, Series 4

IN the past it has not been possible to undertake research work with pigs on any appreciable scale in Western Australia.

A small herd has been maintained at Denmark Research Station for some years as a demonstration side-line unit, run in conjunction with the dairy herd.

A number of very useful trials have been carried out with the Denmark herd, but its size has limited the comprehensiveness of the type of research work that could be undertaken.

Breeding Better Pigs, B M. Goss

Journal of the Department of Agriculture, Western Australia, Series 4

IN the past, pig breeders have tended to select animals on physical characteristics, many of which have little or no relevance to economy of production.

Selection techniques now available open up the possibility of improved pig production efficiency.

Ultrasonic Testing : An Aid To Better Breeding, B M. Goss

Journal of the Department of Agriculture, Western Australia, Series 4

THE ultrasonic tester was originally developed as a metal flaw-detector for industrial purposes, and its usefulness for making carcass measurements on the live pig was first demonstrated about 10 years ago.

The Pig's Need For Minerals, N W. Godfrey

Journal of the Department of Agriculture, Western Australia, Series 4

Only 16 of the one hundred odd chemical elements known are considered to be essential mineral elements for pigs.

As some of these are required in much smaller quantities than others, they are referred to as trace or minor elements, while the remainder are called major elements.

Two Causes Of Reduced Profit From Pigs, G A L Ward

Journal of the Department of Agriculture, Western Australia, Series 4

LOSS of condition in a pig affects profits more severely than slow rate of growth.

Two common symptoms, scouring and itching, cause weight loss and are followed by a period of reduced weight gain.

Housing Pigs, P Mcnamara

Journal of the Department of Agriculture, Western Australia, Series 4

THERE are many designs for pig houses and much will depend on individual circumstances which is best in any particular case.

Practical Disease Prevention In The Pig Herd, R B. Richards

Journal of the Department of Agriculture, Western Australia, Series 4

DISEASES cause loss in pig production through mortality, poor growth rate and reduced food conversion efficiency.

The cost of drugs and expert advice causes further economic loss, and the dangers to public health and to other livestock in a community are serious and often-neglected considerations.

Profitable Bacon Production In A Small Herd, B M. Goss

Journal of the Department of Agriculture, Western Australia, Series 4

PIG HERDS are tending to become larger and more specialised, but it is still possible for the small herd of less than 20 sows to absorb by-products and spare labour very profitably.

These advantages can be lost if the scale is larger.

Swine Fever And African Swine Fever, V W. Smith

Journal of the Department of Agriculture, Western Australia, Series 4

PIGS may become infected by viruses which also cause disease in other animals (for instance foot-and-mouth disease) but there are two virus diseases worthy of special mention because they cause clinical disease in pigs only.

Disposal Of Effluent From Piggeries, P Mcnamara

Journal of the Department of Agriculture, Western Australia, Series 4

ONE of the major problems associated with an intensive piggery is the disposal of the effluent; the nearer the piggery is to urban areas, the greater the problem.

Home Mixing Or Purchased Feeds?, P Mcnamara

Journal of the Department of Agriculture, Western Australia, Series 4

FEED is the largest single cost in pig production, so any saving which can be made will be of major importance.

The Western Australian Pig Industry, P Mcnamara
