Hi
You will find this information on the BHPS website. However in easy to understand terms this should clarify.
No hog is guaranteed to come out of hibernation regardless of weight.
The guidance for hogs used to be 600g to stand a good chance of hibernation – and this still applies for hogs that have been in captivity and are being released in winter. The fat stored during captivity is often lost within the first weeks of release. Therefore the guidance is to make them heavier than necessary so that they stand a better chance of being at 450g to hibernate.
For wild hogs that we have not brought into captivity the guidance is 450g so this would apply to your hogs
The best thing everyone can do is put out food/water throughout the winter and let the hogs do their own thing.
