The figure was almost by the middle of the page, search for the string “AT THE FEEDLOT, CATTLE ARE FED A DIET OF 80% GRAIN AND 20% FORAGES. (SILAGE AND HAY)”, on the section “Start weight, finish weight”.

As for the others:
Here’s the USDA source: https://www.ers.usda.gov/topics/crops/corn-and-other-feed-grains/feed-grains-sector-at-a-glance/:

Corn is a major component of livestock feed. Feed use, a derived demand, is closely related to the number of animals (cattle, hogs, and poultry) that are fed corn and typically accounts for about 40 percent of total domestic corn use. The amount of corn used for feed also depends on the crop’s supply and price, the amount of supplemental ingredients used in feed rations, and the supplies and prices of competing ingredients.

And regarding soy, here’s from the WWF: https://wwf.panda.org/discover/our_focus/food_practice/sustainable_production/soy/

We may not eat large quantities of soy directly, but the animals we eat, or from which we consume eggs or milk, do. In fact, almost 80% of the world’s soybean crop is fed to livestock, especially for beef, chicken, egg and dairy production (milk, cheeses, butter, yogurt, etc).

You obviously know way more than me about the subject but you gotta excuse me for taking anything from a website called “sacredcow” talking about the “plant-based industry” at the top of the page with a grain of salt, everything else I’ve seen online points to animal farming being incredible inefficient and a huge contributor to global warming and water waste.

A supermajority of animal feed comes from the waste product of crops we that were being grown anyway

According to the Alberta Cattle Feeders Association, 80% of the feed is composed of corn. According to the USDA itself half the corn grown in the US was used for animal feed, and 78% of the world’s soy production is made for animal feed.
Is the waste product of corn and soy included in these numbers?

You’re free to do whatever you want, all I meant is decreasing meat consumption not only will reduce the amount of big animals killed, but also the number of smaller ones. Growing a cow takes a whole lot of grain.

Cows and chickens gotta eat too, and that food is coming from fields as well.
By reducing meat consumption also way less critters will end up dying.

You can also find them in North America, in Vancouver!

Such an awesome party game! Absolute recommendation.
