Identification Of A Genetic Marker For Litter Size In Sheep, Olivia Price
Identification Of A Genetic Marker For Litter Size In Sheep, Olivia Price
Undergraduate Honors Capstone Projects
The purpose of this experiment was to determine if the estrogen receptor gene (ESR) could be used as a genetic marker for litter size in sheep. The estrogen receptor gene was chosen because it has been successfully used as a genetic marker for litter size in swine. In this study, DNA dilutions from two experimental flocks, totaling approximately 200 animals, were used. Amplification of exon 1/intron 1 of the ESR gene was performed using PCR. Initial results indicated a polymorphism in the gene when cut with the restriction enzyme Ava ll. It appeared that the gene contained a deletion with …

Sheep And Wool Industries Need To Improve Their Performance, Rob Kelly, Tim Marshall
Sheep And Wool Industries Need To Improve Their Performance, Rob Kelly, Tim Marshall
Journal of the Department of Agriculture, Western Australia, Series 4
Today in Western Australia, sheep are run at slightly higher stocking rates, are achieving greater lambing percentages (up JO per cent) and higher wool cuts per animal ( up 0. 6 kg greasy) than in the 1960s. When all components of production are considered, the productivity of sheep fanns has increased by 2. 7 per cent per year over the past 35 years.
The challenge of the next decade is to achieve substantially greater rates of improvement than for past years if the sheep and wool industries are to maintain their significant place in Western Australian agriculture.
Artificial Insemination Of Ewes With Frozen Semen, David Windsor
Artificial Insemination Of Ewes With Frozen Semen, David Windsor
Journal of the Department of Agriculture, Western Australia, Series 4
The judicious use of artificial insemination (Al) of ewes with frozen semen by ram breeders offers substantial gains for wool producers, but it promises even greater benefits if it can be used more widely within commercial breeding flocks.
In the Western Australian dairy industry, for example, genetic gains between 1971 and /986 are estimated to have been three times as great in herds bred by Al as in herds that were mated naturally.

Differences Between Merino Strains And Studs, Roger Lewer
Differences Between Merino Strains And Studs, Roger Lewer
Journal of the Department of Agriculture, Western Australia, Series 4
When commercial wool growers select Merino rams they often use the following pattern: the buyers first consider the main strains of Merinos in Western Australia - Bungaree, Collinsville and Peppin. They then study the 550 studs and numerous non-stud ram breeders in this State. Having chosen a breeder, they examine the rams on offer and buy their annual requirements from among these. Until recently, no objective information has been available on the differences between studs and strains in Western Australia's agricultural areas. However, as part of a major study at the Department of Agriculture's Great Southern Agricultural Research Institute, these …

Journal of the Department of Agriculture, Western Australia, Series 4
Farmers can increase sheep numbers by mating ewe weaners. Trials have shoen that this does not affect the later performance of these ewes.
Objective Measurement And The Stud Breeder, B R. Beetson
Objective Measurement And The Stud Breeder, B R. Beetson
Journal of the Department of Agriculture, Western Australia, Series 4
The movement towards sale of wool by certificate and sample highlights the significance of objective measurement in the Merino stud breeders' selection of his top rams.
This article suggests how stud breeders should use the Department of Agriculture's Flock Testing Service to gain genetic progress in wool producing ability without loss of visual buyer appeal.
Studs' use of the service will be evaluated in 1974.
Sheep Meat Production Trial, Department Of Agriculture, Western Australia
Sheep Meat Production Trial, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
Better understanding of Middle- East, European and Asian market requirements for Australian sheep has influenced the design of a large meat production trial at Avondale Research Station.
The trial will supply basic information on sheep meat production and involves examples of breed types available in Western Australia and capable of supplying young, lean animals all the year round.
Later Mating Improves Lambing Results, R J. Suiter
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
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
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 …

Special Field Days For Merino Breeders, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
More than 200 Merino stud breeders attended special stud breeding and fertility field days arranged for them by the Department of Agriculture recently.
Breeders attending represented some 40 per cent of the State's Merino studs.
Twinning Increases Production, K P. Croker
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.

Famous Sheep Breeds. 6. The Southdown, J A. Mallett
Famous Sheep Breeds. 6. The Southdown, J A. Mallett
Journal of the Department of Agriculture, Western Australia, Series 4
THE chunky, low-set, meaty-carcassed Southdown is a popular breed wherever prime mutton and lamb are appreciated.
Just as the Dishley Leicester was used to improve most of the British longwool breeds, so an infusion of Southdown blood has benefited the majority of the British shortwool sheep whose main role is meat production
