Veterinary Medicine - ideal work experienceWatch
She did a couple of years of Sunday mornings at a mixed animal rescue, 2 stints of lambing, a day each milking and beef, a week at a zoo, several weeks small animal practice (in week long sessions) and just one day of large animal as that is all she could get, a week at a donkey sanctuary.
A day at an abattoir is enough - she didn't get this.
Others have much more, particularly large animal and equine that she was light on. She got offers from her 2 top choices.
Like above, lambing is really great. I think it's really important to get some lambing before uni but people do get in without. My advice would be to achieve what you need for your applications and do as much more as you can/want to in the same areas or different things as it really boosts your application.
Veterinary practices will be flat out now and very unlikely to take even vet students let alone pre vet so considering you have time I would save these for next summer when hopefully the situation will be much better. Lambing depending where you are in the country begins around late november and goes on until shortly after easter - plenty of time to get 2 weeks in.
Focus on getting the core placements (Cattle, sheep, pigs, equine, small animal, and smallies/farm/equine vets) before going for the more 'bonus' placements - e.g. an abattoir (very well liked) or laboratory.
Also do not be suckered into pre-vet courses - they are often totally unlike the actual vet course, and do not count as experience due to their inflated financial cost making them unequal to applicants.
