This paper reviews potential benefits of beef cows to other livestock
enterprises on a sheep and beef farm. These benefits may include general
benefits of cattle such as improved sheep performance via improved pasture
quality. They may also include benefits specific to cows such as the efficient
use of low quality feed and feed demand patterns which match pasture
production. A linear programming model is used to quantify complementary
benefits of breeding cows to the total farm economy. This is done by
comparing the profit from finishing only policies with those that include
breeding cow and finishing cattle policies. When the marginal benefit in farm
profit is all attributed to the breeding cows their worth is between 5 and 26%
greater than estimated by an enterprise analysis which does not account for
complementarity. However, complementary benefits cease when returns from
finishing reach $16/su greater than cows. Field system trials are required to
validate these conclusions.
