Farming operations are complex. The following pros and cons have not been factored into this calculator:

• It is common for 40% less labour to be needed using Advantage Feeders compared to trail feeding three times per week.
• Reducing labour at seeding time can allow farmers to prioritise this time critical task and reduces the risk of the livestock component of the enterprise being neglected.
• It is important not to have too few feeders during lambing because ewes on the verge of lambing may attempt to steal the lambs off other ewes that have just lambed.
• If lambs are subsequently creep fed, they will be mostly trained by their mothers, getting them accustomed and trained to the feeders.
• Providing supplement on the ground can make it more likely that stock digest worms from faeces that the feed was placed on. This increases the expense of managing parasites.
• It is common for feeders used in this calculator to be used for other purposes at different times of the year. This reduces the depreciation expense and increases the return on investment.
• Trail feeding leaves grain that can germinate in future crops, contaminating them and downgrading the value of those crops.
