	abstract = {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. },
