Economics summary

First period

return

Second period

return

Full year

return

Leucaena 21.35% Leucaena 7.84% 32.12%

Oats 7.22% 30.68%

Feedlot 11.88% 36.01%

Grass 9.41% Grass 8.45% 19.78%

Compared using “partial return on livestock capital invested”

‐ takes into account the different capital investments necessary to make

the steer finishing systems operate and therefore makes adjustment for

the differing stocking rates and periods of time

13


• All the finishing systems produced highly profitable

results

• The three high input systems were more profitable

than the 12 month improved pasture system under

the seasonal conditions and prices encountered.

Cost of gain excludes labour and selling costs

Grass $0.68/kg

Leucaena $0.61/kg

Oats $1.75/kg

Feedlot $2.04/kg (feed only; feed conversion is 8.5kg

as fed basis)

14


Urine results

10 weeks (remained yellow/straw coloured)

‐ seems that the toxin is not present, suggesting the bug has

circulated through the mob and working

18 weeks (one remained yellow; others went more orange)

‐ potentially some level of 3,4‐DHP present but not likely to

be above the threshold

Toxin levels suggest that performance should not have been

affected in this demonstration
