Maintaining Ewe Bodyweight For A Late Mating, T Marshall
Maintaining Ewe Bodyweight For A Late Mating, T Marshall
Journal of the Department of Agriculture, Western Australia, Series 4
DEPARTMENT OF AGRICULTURE experiments have indicated that the bodyweight of ewes at mating can have a large bearing on lambing performance.
It appears that for every 10 lb. increase in pre-mating bodyweight, an increase of some 3 to 6 per cent, lambs born could be expected, depending on the lambing time.

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.
High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter
High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter
Journal of the Department of Agriculture, Western Australia, Series 4
Analysis of lambing trials with Merino ewes has shown a highly significant association between pre-mating liveweight and lambing performance.
With May-June lambing ewes there was a 2.9 per cent, lambing increase for every extra 10 lb. liveweight; for July-August- September lambing ewes there was a 6.9 per cent, increase for every 10 lb. liveweight increase.
With the May-June lambing there was a critical weight below which twinning was negligible.
Rearing Orphan Kangaroos, G L. Ward
Rearing Orphan Kangaroos, G L. Ward
Journal of the Department of Agriculture, Western Australia, Series 4
LICENCES are required in Western Australia if certain kangaroos and all species of wallabies are kept in captivity, but orphaned young joeys often need care and hand feeding before they can be released to fend for themselves.
Lupins In Western Australia. 5. The Grazing Value Of Green And Mature Lupins, John Sylvester Gladstones
Lupins In Western Australia. 5. The Grazing Value Of Green And Mature Lupins, John Sylvester Gladstones
Journal of the Department of Agriculture, Western Australia, Series 4
WHETHER or not lupins are grown primarily as a grain crop, grazing of standing crops and harvested stubbles will continue to be an important use. This article examines the uses of sweet lupins for forage, and the main problem of lupin grazing, lupinosis.
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 …
Inoculation Abscesses Can Downgrade Carcasses, M R. Gardiner
Inoculation Abscesses Can Downgrade Carcasses, M R. Gardiner
Journal of the Department of Agriculture, Western Australia, Series 4
THE presence of inoculation abscesses in meat is one of the lesser known causes of downgrading or rejection of carcasses, but these abscesses have caused increasing concern in recent years.
They have obvious importance in export carcasses.
The New Stock Diseases Regulations : A Summary Of Major Regulations Under The New Stock Diseases (Regulations) Act, M R. Gardiner
The New Stock Diseases Regulations : A Summary Of Major Regulations Under The New Stock Diseases (Regulations) Act, M R. Gardiner
Journal of the Department of Agriculture, Western Australia, Series 4
THE new Stock Diseases (Regulations) Act proclaimed on August 1, 1970, introduces some new regulations and makes many changes to existing regulations, which could affect most farmers at some time or another.
This article summarises the regulations most likely to affect farmers, with emphasis on new or changed regulations.
A Control Programme For Cheesy Gland In Sheep, M R. Gardiner
A Control Programme For Cheesy Gland In Sheep, M R. Gardiner
Journal of the Department of Agriculture, Western Australia, Series 4
CASEOUS LYMPHADENITIS, or "cheesy gland" as it is usually known in Australia, is a common disease of sheep which is very important in the economics of the lamb and mutton industry.
Effects Of Mastitis On Milk Yield And Composition, Department Of Agriculture, Western Australia
Effects Of Mastitis On Milk Yield And Composition, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
EVERY DAIRY farmer knows how much he spends on the treatment of cows affected with mastitis, but the actual loss in production is more difficult to estimate.
As part of the current mastitis research programme the Department of Agriculture's Animal and Dairying Divisions surveyed 37 dairy herds with a believed high incidence of mastitis.

Submitting Plants For Disease Identification, M D. Marcley
Journal of the Department of Agriculture, Western Australia, Series 4
THERE are several important points to remember when submitting plant material for disease identification by the Department of Agriculture's Plant Pathology Branch.
