Shed Lambing In The Esperance Environment, T Marshall, F. F. Dixon

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

Neonatal lamb mortality is often high in Western Australia and losses as high as 33 per cent, have been recorded on private properties in the Esperance area. Surveys by Western Australian Department of Agriculture officers have indicated that more than threequarters of such lamb deaths occur after birth. About half these deaths result from the combined effects of weather and mismothering.

Work in Victoria has indicated that lamb mortality may be reduced by intensive lambing systems such as shedding and this trial was established to see if shedding could reduce lamb mortality in the Esperance environment.

THE OCCURRANCE of mycotic dermatitis in sheep in Western Australia, although rather unpredictable, is quite frequent throughout the higher rainfall districts.

Similar outbreaks are likely among late winter-spring born lambs. This article describes the disease and suggests measures for prevention and treatment.

Drenches For Treatment And Control Of Worms In Sheep : 1969 : Efficiency, Cost And Safety, W A. Halhead, G. De Chaneet

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

THERE is a wide variation in the efficiency and cost of drugs for worm control in sheep.

Generally, the higher the efficiency, the greater the cost. Prices are subject to change, and may vary with the amount of drench purchased.

Sheep Worm Control And Lambing Time In High Rainfall Areas, F C. Wilkinson

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

Indications from a continuing sheep trial at Margaret River are that farmers in high rainfall areas could increase stocking rates and lamb growth rates by lambing in September- October rather than July-August.

The results also indicate that farmers in the area may be spending more than necessary on worm control.

Sheep Drenching Programms, Department Of Agriculture, Western Australia

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

Drenching of sheep to prevent build-up of worm infestations is commonly practised on many properties in the agricultural districts of Western Australia. This is called strategic drenching.
