Dairy cattle in Nevada have been infected with a new type of bird flu that’s different from the version that has spread in U.S. herds since last year, Agriculture Department officials said Wednesday.

The detection indicates that distinct forms of the virus known as Type A H5N1 have spilled over from wild birds into cattle at least twice. Experts said it raises new questions about wider spread and the difficulty of controlling infections in animals and the people who work closely with them.

“I always thought one bird-to-cow transmission was a very rare event. Seems that may not be the case,” said Richard Webby, an influenza expert at St. Jude Children’s Research Hospital.

    but where did you get those? because i’ve found some LCA meta “studies” that i don’t trust which are usually the ones trotted out. i was hoping you had good data sources.

      I mean I have never looked into the studies that are the basis for the data but while I think its possible in the details I really doubt the overall would be wrong. Water usage and calorie wise it pretty much falls in line with smaller animals using less for each calorie. I really doubt people are hyping crickets capability to convert plants into cricket vs cows making plants into cow. Its common sense enough that Im not looking to determining how well the studies were done as I don’t do that for most things as most people don’t who still work a job enough to eat and such. Conversely if you know about bad studies I would not mind you giving me what you have. I have just done a quick search using terms like misleading and scam and such and nothing seems to come up.

        poore-nemecek 2018 is oft-cited. it is the one that is often used to justify the claim you made. but that meta “study” misuses its source data: LCA findings are not transferable between studies. this is explicitly stated by some of of the source papers which also violated this rule, but poore and nemecek disregarded this guidance and didn’t even mention it.

          I feel there should be earlier things as I swear I saw similar things before 2010. Im looking into poore-nemecek but im not sure if its even the same thing as it seems to be about co2 and global warming as opposed to water usage or calorie usage.

              The only things im finding so far is real bullshit. Claims of soy and corn grown for human used and the cows just getting the waste when we grow specifically feed corn. Im still looking for some legitimate critique article.

                  are you asking me to judge their methodology because it is way out of my field. Again though what I am seeing of critiques themselves have issues I can see and if I see something I no is not correct like the animal feed thing then I discount the whole critique because I do not feel I can trust it. As for other sources I can say going back I can find thes about conversion https://awellfedworld.org/feed-ratios/ and its source material in most cases is industry information.

                    I assure you it is written in plain English. no hard math is required to understand that they compiled data that was collected with disparate methodologies, and did so against the express direction of the original authors as well as accepted practice. further, the failed to disclose this, even when citing papers which committed the same faux pas which did disclose it.
