Prime Lamb Production In Western Australia : A Review Of The Development Of The Prime Lamb Industry In Western Australia, R J. Suiter

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

PRIME LAMB production in Western Australia has evolved into an industry based almost entirely on the local market.

This has not always been the case. In the 1930-40 era a substantial proportion of the State's prime lamb production was exported to the United Kingdom.

During this era the industry was equally dependent on exports and local market.

Later Mating Improves Lambing Results, R J. Suiter

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

Ovulation studies in Western Australia have indicated that increased lambing percentages in crossbred and Merino ewes could be expected from mating in February-April rather than December- January.

Such increases have been demonstrated in time of lambing trials with crossbred ewes, but had not been seen in Merino flocks until recently.

This report summarises the results of time of lambing trials with Merinos carried out at the Merredin and Wongan Hills Research Stations between 1963 and 1969.

Choosing Your Lambing Time, T Marshall

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

SHEEP, pastures and labour are the major resources of the sheep enterprise but their productivity is greatly affected by the timing of operations associated with them.

This article discusses how the lambing time can be chosen to get maximum use from each resource.

Causes Of Low Lambing Percentages, Department Of Agriculture, Western Australia

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

West Australian Merino flocks average about 70 per cent, lambs marked each year. Reasons for this low percentage are that as many as 30 per cent, of ewes do not lamb, twinning rates are low and from 10 to 25 per cent, of lambs born die.

Among the research projects by the Department of Agriculture's Sheep and Wool Branch have been a number directed at the various stages of reproduction in the ewe. These have given some important leads on the causes of low lambing percentages.

If you have marked less than 60 per cent, lambs in the past several …

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.

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.

Twinning Increases Production, K P. Croker

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

Many breeders claim that twinning causes too many losses among Merino lambs and does not favour breeding for twin lamb production.

But recent experiments have proved otherwise and agricultural scientists now agree that . . .

TWINNING INCREASES PRODUCTION

THE low marking percentages regularly recorded for Merino flocks suggest that the Merino is a relatively infertile breed.

Certainly, lambing percentages are low when compared with those of most British breeds of sheep.

How To Identify Twin-Born Lambs, G T. Halpin, P. Nelson

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

IN the past few years it has become widely accepted that the ability to produce twin or multiple lambs is a heritable characteristic.

This means that breeding from sheep born as twins should give more multiple births and higher lambing percentages than breeding from sheep born as single lambs.
