Stocking Rate And Wool Production At Kojonup, Davies H. Lloyd, A. W. Humphries

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

RESEARCH workers in several parts of the world have recognised the overriding importance of stocking rate in raising animal production per acre.

This article describes some of the initial work on the effect of stocking rate on wool production and liveweight change in medium-Peppin Merino sheep.

The work was carried out at the C.S.I.R.O. "Glen Lossie" Field Station at Kojonup, Western Australia.

Urea For Sheep And Cattle On Dry Feed, Laurence C. Snook

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

Urea can be a valuable supplement for ruminants which have to depend on dry feed low in protein.

It is not a substitute for good quality conserved fodder.

Urea is extremely poisonous if eaten in excess and great care must be taken when feeding it to stock.

There are a variety of ways in which urea can be fed and these are outlined in this article.

The Department of Agriculture's Animal Nutrition Laboratory is now carrying out trials to determine the most convenient and safest method.

Urea is most effective as a fertiliser; when used in this way it results …

Ewe Nutrition Before And During Mating, H E. Fels

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

Lambing percentages depend partly on the condition of ewes at mating. If it is practicable, ewes should be allowed to gain condition in the months before mating.

Where this is not practical and ewes are in a store or backward-store condition at mating, flushing should improve their fertility.

Lambing Trials At Abydos Research Station, H Suijdendorp

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

ABYDOS Research Station is halfway between Port Hedland and Wittenoom Gorge. I t is in country of granitic origin that is largely covered with spinifex (mainly Triodia pungens) and associated species.

The results of a recent lambing trial at Abydos are discussed below:

Weaner Feeding Practices Need Review, W L. Mcgarry, R. J. Lightfoot

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

Many fanners feed large amounts of grain to their weaners over summer and autumn, in the belief that this is necessary for high lifetime production.

The economics of this are open to doubt; in fact, the results of a recent experiment at Wongan Hills Research Station suggested that weaner feeding practices need review.

Time Of Lambing Experiment : Merredin Research Station, 1959-60 (Progress Report), W L. Mcgarry, I. K. Stott

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

FOLLOWING upon the Time of Lambing Experiments at Esperance Plains Research Station (Journal of Agriculture, May, 1960) it was decided to carry out similar work with Merino sheep under the relatively harsher environment at Merredin Research Station.

Autumn Lambing Means Autumn Feeding, C J. Spencer

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

MANY Merino flocks in the agricultural areas Iamb down in the autumn months.

This means that the lambs are being developed and reared when paddock feed is at its worst, and this in turn means that a well-planned supplementary feeding programme is essential.

Studies In The Mulga Pastoral Zone. 2. Some Aspects Of The Value Of The Mulga Scrub, D G. Wilcox

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

THE mulga pastoral zone is so named since most of its area is dominated by Mulga (Acacia aneura).

The mulga is found associated with shrubs and grasses in almost all plant habitats. In its various forms it can associate with spinifex (Triodia basedowi), Wandarrie Grasses (Danthonia, Eragostis and Eriachne spp.) and with low shrubs on flood plains, hills and breakaways. It may even attempt to become established in salty communities, though this is never completely successful.

The scene the area offers from its low hills is one of a succession of low undulations, occasionally scarred by creeks or breakaways and …
