This trial took part in Brazil in 2016.
Three different farms were chosen to cover all facets of the market.
Farm 1
A small traditional family run farm
Farm 2
A medium sized operation operating in a traditional way but with some technology
Farm 3
A large commercial operation with large staff and modern equipment
All three farms were traditionally using a fast feeding teat with a valve fitted.
Calves were monitored for weight, behaviour (cross suckling and contentment), time factors and appearance and quality of the calves.
