Sure, people cite online stuff more, because people are lazy. But I haven't seen any bias against people who do cite books. That's mostly what I cite, since I write articles while I'm working my way through books, citing the book in the process. People seem to actually welcome it, if anything. I've added some information not previously available online that way about some archaeological sites, Greek wines, old AI systems, and a few other things. I've gotten only positive comments from doing that, which makes it extra-weird that people say Wikipedia is so unfriendly to contributors. No bureaucracy or acronyms or anything; just a few paragraphs with a citation to a book or two, click save, done.
Surely there must be books on animal husbandry that can be used to improve the articles? There has to be something, because I don't think Wikipedia should let you just cite "trust me, I know this". As a reader, I don't want to have to trust Wikipedia; I want Wikipedia to point me to somewhere where I can follow it up.
I do agree that there is a huge pile of stuff only covered in books that is under-covered on Wikipedia currently, due to nobody having gone to the library and dug up the information yet. It's got 3.8 million articles in English, but I think is not even halfway "done".
"But I haven't seen any bias against people who do cite books."
If you recall the great programming language AfD wars of recent. The problem was precisely that the editors exhibited an extraordinary bias against two things:
a) references of printed material -- because they didn't have a copy so they couldn't verify it, and/or the proceedings were not perceived to be notable enough on that particular editors radar to be counted
b) references of printed material in another language - as odd as it may seem, people who communicate in other languages do have something to say and produce material that can be referenced. But because the editor couldn't read that language, it was dismissed.
I'd believe what you posted, the trouble free utopian life of a contributor, maybe 5 years ago when one could actually contribute to WP without having all their changes reverted followed by snide comments from capricious editors. But the reality is that there are very large numbers of people who won't even be bothered contributing anymore (and you can see a fraction of a percent represented in the comments here) because the experience of doing so was shamefully poor.
If anything, I've found the experience has gotten better over the past few years, in that "notability" has been almost entirely trumped by "verifiability". These days, if I write an article with a few solid sources, I don't get hassled at all. I just wrote something a few days ago on an Ottoman-era castle in Greece, citing an offline (and not even very easy to get) book, and nobody hassled me.
I mean, you don't have to believe it, but I would guess that if you pick up a solid book, and write some well-referenced articles based on it, you aren't going to have problems either.
