Unprocessed dried soybean in moderation, is it OK for rabbits?

[Bike guy]

I want to add unprocessed dry soybean to my rabbits diet fot it's high protein content, soybean will make up nomore than %1-3 of their total diet. My concern is not about estrojen levels, all my rabbits are female except one cub and I don't think %1-3 will cause problems. But I think there are other concerns about unprocessed soybean such as it's outer part which contains high levels of starch.

Soybean is not exactly known by people in my country. This is the soybeans that I bought, I'm completely allien to soybean, never ate them and this is the first time I see soybean. Do this spicemens look OK? (Are they even soybean lol)

Do you think is it OK to feed bunnies in moderation?

Those do look like soybeans. As I understand it, soybeans must NOT be fed raw. I used to buy an organic feed that had soybeans in it. They were roasted and ground into meal, which gave the feed a rather pleasant, peanutty smell.

You need to do further research. If you google Are soybeans good for rabbits? you will find a lot of information. Don't stop reading after just one site. Get a good complete understanding of the subject.

The small amount of research I have done came up with what MaggieJ said, they need to be roasted. I have a friend with a pelleting machine who wanted to make me pellets and roasted ground soybeans are one of the easier ingredients for her to source. Haven't tried it yet though.

"Feeding raw soybeans can have a detrimental effect on single-stomached animals. The reason for this is that they contain a trypsin inhibitor that prevents protein uptake. The beans also contain a protein called Soyin which, when raw, can be toxic.

By heat-treating soybeans, these problems can be removed, leaving a high protein product.

Soybeans are the most common protein crop for feeding to livestock in the world. Roasted soybeans are more suitable for single-stomached mammals and poultry than for ruminants, which do better on soy meal."
