Studley Grange Butterfly World & Farm Park has invested in an ultrasound machine.
The team at the attraction, near Wroughton, will use the machine to monitor pregnancies and predict dates of birth.
A spokesperson said: “This is a great addition to our farm equipment.
"It will allow us to accurately assess not only which animals are pregnant, but also the amount of young being carried and likely due dates."
The information the machine provides will enable the farm team to tailor care and feed to individual animals, and will also be used as a learning tool for work experience students and visiting school groups.
It will also be used during courses for smallholders which are planned for next year.
