You mean, compared to what goes to the market for people?
I don't eat much of not industrial agriculture products, even local farms only produce fruits, and I would say they are also industrial (not sure where is the line)
More than three-quarters of global agricultural land is used for livestock, despite meat and dairy making up a much smaller share of the world's protein and calories.
[...] However, only half of the world’s croplands are used to grow crops that are consumed by humans directly. We use a lot of land to grow crops for biofuels and other industrial products, and an even bigger share is used to feed livestock.
As per the article two thirds of that 'agricultural land' is graze-lands, so like a 12.5% of that agricultural land is actually farmland dedicated to feed livestock.
I see, 25% is still not too little, I expected this to be less than 10% based on how you phrased the first comment. But you're right, it's possible to greatly reduce strain on land
