Book says fresh potatoes as part of winter root ration. But its only mentioned in one of the four books.
I realise that in an ideal situation there wouldn't be any suspected questionable plants available to livestock but everyone and all books say that goats thrive when working away free range at overgrown scrub or undergrowth in open woodland. I have this available, as well as fields, but It would not be practible to remove everything I've found on the harmful to goats lists, and to be honest I don't want to (snowdrops, bluebells, foxgloves, honeysuckle).
Had anyone ever known a goat to get ill after eating any plant growing In it's field?
I've always been taught that ragwort is lethal, spent weeks pulling it up and I did read on here the other day that it is accumulative in the liver, but to be honest I've also known plenty of ponies in their 30's in fields with all the listed harmful goat plants, and ragwort and find myself questioning the evidence behind their inclusion. Plus some books saying goats are more tolerant of ragwort, others saying goats learn what to avoid, makes me wonder if live stock really do get sick from all the listed plants in real life.
Edited to add:
Read on ragwort.org.uk that iragwort toxins does not accumulate in the liver over years, rather the damage to liver cells does if eaten often.
I've also read that confrey contains the same toxins, purrolizidine alkaloids, and comfrey is listed as good goat food. (Not found out how much is in each plant yet.)
I have read a reference to, but not the original paper, Goeger et al., 1982 - goats are much less susceptible to ragwort poisoning than horses. Needing to eat over 125% their body weight. I will dig out this original paper.
