Feeding Urea To Cattle, D J. Barker
Feeding Urea To Cattle, D J. Barker
Journal of the Department of Agriculture, Western Australia, Series 4
RUMINANTS normally obtain the protein they require by digestion of the organisms that inhabit the forestomach (rumen), not by direct digestion of the dietary protein they chew up and swallow.
The organisms break down the dietary protein and then rebuild proteins in the form of more organisms.

Recent scientific reviews have concluded that in spite of the great number of experimental observations recorded throughout the world there is no evidence yet to prove that urea can be used profitably for sheep on low quality roughages in genuine grazing conditions.
An experiment is in progress at Merredin Research Station this season, especially designed to demonstrate a response to urea by sheep grazing wheat stubbles, if such a response is possible.

Many District Advisers have carried out trials on private farms to test the response to a variety of types of supplementary feeds. This report gives brief details of five such experiments carried out with urea supplements over the last five years. Table 1 summarises the details and results of these trials.

This experiment was done once the experiment above (Urea or Grain Supplements for Stubble) had shown definite but uneconomic responses to a particular mixture of urea, molasses and minerals. The aim was to find whether the response depended on the content of various portions of the mixture, and whether the response to the "shotgun" lick could be explained by the presence of salt, sulphate or cobalt.

Trials in 1968 at Burracoppin and York again showed it is safer to topdress urea just before seeding than to drill a mixture of seed and urea.
At all but the lowest urea rates, urea drilled with the seed reduced the number of plants emerging and surviving, and reduced final wheat yields.

Three methods of supplementing sheep grazing stubble were compared at Merredin Research Station in 1970. The stubble used in the experiment was left after harvesting a nine-bushel crop of Gamenya wheat which was a weed-free second crop on new land. The land had never been sown to legumes.

THERE was a great deal of controversy throughout the summer of Western Australia's 1969-70 drought over the feeding of supplements other than grain to grazing sheep.
This report summarises some of the experiments carried out by this Department to investigate various artificial means of supplementing sheep grazing stubbles and dry summer pastures.
Further details of the experiments can be obtained by contacting the authors.
The results failed to demonstrate economic responses to urea supplements for grazing sheep.
