| Since World War II there has been a rapid increase in the area sown to improved pastures in Australia generally and New South Wales in particular. Despite this increase there has been much speculation as to the reasons why even more country has not been improved, especially as spectacular increases in carrying capacity result. There have been a number of studies of economic aspects of pasture improvement stimulated by these observations. This study is intended to extend or supplement them, because much of the previous work has been somewhat limited. The objects of this paper are to:- (1) Outline the basic asumptions on which the whole study is based. (2) Determine, where finance is provided from savings supplemented by reinvestment of all profits (when... |

| An attempt was made to quantify some of the variables which affect mating strategies on the Northern Tablelands in the high rainfall zone of New South Wales. A single year linear programming model was developed which permitted the determination of the optimum date of lambing of a Merino X Border Leicester ewe flock (composed of four tooth, six tooth, and full mouth ewes and mated to Dorset Horn rams) for a range of prices and seasonal conditions. It was found first, that generally a staggered lambing is most profitable; secondly, that it pays to lamb early for the Christmas-New Year market if premiums are adequate; and thirdly, that it pays to buy considerable quantities of oaten grain for winter feeding. |
