Calfhood Diseases. 1. Gastro-Intestinal Diseases, M R. Gardiner

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

CALFHOOD disease may be divided for convenience into three main categories:

• Those affecting the gastro-intestinal tract, including diseases of an infectious nature and those arising as a result of infestation by worms (parasitism).

• Those affecting the respiratory system, including lungworms.

• Those resulting from nutritional deficiencies, especially vitamins and minerals.

Weed Control In Irrigation Channels, Geoffrey A. Pearce

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

Probably the major task involved in maintaining drainage and irrigation channels is the regular removal of weed growth.

The cost of hand chipping a standard head channel is approximately 10s. per chain.

The use of suitable chemicals could reduce this cost considerably.

Mastitis : Prevention And Control. 2. Principles Of Mastitis Control, F C. Wilkinson

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

MASTITIS is a major cause of financial loss in over half our dairy herds.

Losses result from treatment costs, milk discarded, permanent loss of milk production, culling, lowering of solids-not-fat content and loss of butter-fat production.

Mastitis CAN be controlled. This article outlines the basic principles of mastitis control in the milking shed.

Seed And Pasture Rates For New Dairy Pastures, F E. Ryan

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

THE success or failure of pasture establishment on new land often depends on the interaction of rate of seeding and rate of superphosphate application.

Every year large areas of virgin land are cleared and sown to pasture in the higher rainfall areas, and all-too often the new pasture is not as successful as it should be because too little super is applied, and, in some cases, too little seed.

Why Did These Lambs Die?, Stanley M. Dennis

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

INVESTIGATIONS over the past two years have shown that most lamb deaths in Western Australia occur during the first three days of life, that is, in the critical neonatal period.

In this article Dr. Dennis discusses the causes of abnormalities and reports progress of a Statewide survey of congenital abnormalities.

Predators : Lamb Killers Or Scavengers, Stanley M. Dennis, C. D. Gooding

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

PREDATORS, particularly foxes and crows, have long been considered by many farmers in Western Australia to be a serious cause of lamb losses during the first week of life.

Results of the post-mortem examination of 2,179 lambs carried out by the Animal Health Laboratory over the past two years, however, throws considerable doubt on this belief.

These examinations revealed that 34 per cent, of the lambs showed mutilation by predators but only about 2 per cent, actually died as a result of predator attacks.

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

WHILST it is generally known that medicines sold for human use are the concern of the various health authorities throughout Australia and that many precautions are taken to ensure that these are both safe and efficient, it may not be so widely known that the sale of preparations for both internal and external use in stock is controlled for the same purposes by the veterinary authorities.

Lot Feeding Of Beef Cattle. 3. Facilities Required For A Feed Lot, W J O Wilkie

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

MANY THINGS must be considered in planning a feed lot.

The site must be well chosen, fencing, gates and yards must be adequate for the cattle carried and feeding and watering facilities should be of a high standard.

Other things to consider are the provision of shelter and shade for the cattle and buildings for feed storage and other purposes.

A Herbicide For Native Poison Plants, Department Of Agriculture, Western Australia

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

THE usual method of killing poison plants is by a programme of ploughing, cropping and burning.

The burning not only destroys a proportion of the plants, but stimulates the germination of dormant seeds, which otherwise would remain in the soil in a viable condition for many years.

Stinkwort (Inula Graveolens Desf.), G R W Meadly

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

THE original home of stinkwort is the Mediterranean region, including northern France. Apparently the first Australian record was at Onkaparinga in South Australia about 90 years ago.

Efforts were made to keep it in bounds during the years immediately following introduction, but it continued to spread and is now f i r m ly established in all agricultural districts of South Australia.

It also covers large tracts of land in New South Wales and Victoria and occurs in most districts of Western Australia.

Root knot eelworm has a wide host range.
