Effects Of Mechanical Processing On The Nutritive Value Of Barley Silage For Lactating Dairy Cows, Jong-Su Eun, K. A. Beauchemin, S.-H. Hong, W. Z. Yang

Animal, Dairy, and Veterinary Science Faculty Publications

Mechanical processing of whole crop barley before ensiling may be useful for improving nutrient use by dairy cattle. The objective of this study was to assess the effects of feeding mechanically processed barley silage as the main forage source on lactational performance. Twenty-four Holstein cows, 16 primiparous (187±52 days in milk) and 8 multiparous (87±69 days in milk) cows, were used in a completely randomized design with a 2-wk covariate period and a 6-wk treatment period. The 2 treatments were: 1) total mixed ration (TMR) containing regular barley silage (RBS-TMR), and 2) TMR containing mechanically processed barley silage (MPBS-TMR). Barley …

Analysing Feeds For Cattle, Sheep And Goats, D J. Barker

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

The Department of Agriculture's Feed Evaluation Unit at Bunbury provides a service for farmers and allied industries on a fee-for-service basis, and conducts analyses for research officers, advisers and organisations such as the University ofWestern Australia. It also analyses feedstuffs for Departments of Agriculture in other States.

The Unit analyses about 5000 samples each year. The work load is high because no other laboratory in Western Australia provides the same service. Results are recorded on a computer which makes it easy t6o retrieve results of analyses of particular types of feedstuffs or froma particular owner or district.

Stocking Rates With Growing Cattle At Wokalup Research Station, Maurice C. Cullity

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

CONSIDERABLE attention has been given in Australia and in overseas countries to methods of grazing control, and to the effects of varying stocking concentrations.

There is evidence that the highest yields per animal—of milk or butterfat per cow, or of weight increase per growing or fattening beast—are not necessarily a true reflection of the greatest output from the farm, as indicated by the measure of yield per acre.

Meadow Hay, Department Of Agriculture, Western Australia

rriHE nutritive value of pasture is high in early spring and remains so until early flowering.

After this the protein content falls rapidly, the fibre content rises and the plants become more lignifled and their digestibility reduced.

Hay For The Dairy Herd : Quality Or Quantity?, F E. Ryan

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

CONSERVATION of hay on dairy farms has increased in recent years but so far emphasis has been on quantity rather than quality and in some districts paddocks are closed up very early to increase yields per acre of hay.

Recent trials have shown that late closing of hay paddocks on dairy farms gives higher quality hay, more winter grazing and a better balanced pasture. The gain in quality more than compensates for any drop in yield.
