Summary

A new H5N1 bird flu variant has become “endemic in cows,” with cases detected in Nevada and Arizona, raising concerns about human transmission.

Experts warn that without intervention, the outbreak will continue, but Trump has cut CDC staff and halted flu vaccination campaigns.

The virus’s spread coincides with a severe flu season, increasing the risk of mutation.

The administration has also stopped sharing flu data with the WHO and shifted its containment strategy away from culling infected poultry, raising fears of inadequate response.

      it’s not mostly kernels. livestock are fed the entire plant, and the kernels are a slim minority of the weight.

      • Weight matters not even a little compared to the caloric content. If cows got more calories out of corn stalks than corn kernels, then they wouldn’t even finish growing the corn and would just feed them stalks. The fact you have to grow a corn stalk that weighs hundreds of times more than the kernels doesn’t mean the kernels aren’t what the farmers are after for livestock feed purposes. The stalk just gets tossed in for efficiency’s sake because the cows can also digest it.

          you literally don’t know anything about feeding cows. just stop.

          . If cows got more calories out of corn stalks than corn kernels, then they wouldn’t even finish growing the corn and would just feed them stalks.

          I don’t think so. they may get more calories from silage, but they prefer the kernels, which would help the feed go down easier.

          • You’re accusing me of not knowing how cows are fed when you’re inventing a world where farmers spend extra time growing crops to make it taste nicer to cows. Be real.

      Raising plants to feed animals so we can eat the animals is less efficient than raising plants for us to eat.

      if that were the situation, you might be right. but since we actually feed livestock mostly crop seconds and byproducts, it’s actually a conservation of resources in a lot of situations, with minimal competition with human food sources

        1 kg of meat requires 2.8 kg of human-edible feed for ruminants and 3.2 for monogastrics

        we show that plant-based replacements for each of the major animal categories in the United States (beef, pork, dairy, poultry, and eggs) can produce twofold to 20-fold more nutritionally similar food per unit cropland. Replacing all animal-based items with plant-based replacement diets can add enough food to feed 350 million additional people, more than the expected benefits of eliminating all supply chain food loss.

          your shepon paper shows a great deal of spinach being fed to chickens. why would it be fed to chickens if it were suitable for human consumption? I don’t actually know, but my guess is that it is not suitable for human consumption, and that is why it is fed to chickens. that’s a conservation of resources. the potatoes fed to cattle are likely the same.

          this paper doesn’t discuss this discrepancy at all. I have to say I don’t find the analysis very compelling.

          do you have the full papers? I can’t really examine these claims from the links you provided.

          soybean cakes, which production can be considered as main driver or land-use, represent 4% of the global livestock feed intake.

          you clipped this out of the abstract, but it’s highly relevant to what I’ve been saying: this is a byproduct of pressing soybeans for oil. if we didn’t feed it to livestock, it would be industrial waste.

      beef cattle spend most of their life grazing.

        Where they emit the most methane and still are given supplementary feed. There’s also not enough land to sustain a grazing only production system with the massive demand we have

        We model a nationwide transition [in the US] from grain- to grass-finishing systems using demographics of present-day beef cattle. In order to produce the same quantity of beef as the present-day system, we find that a nationwide shift to exclusively grass-fed beef would require increasing the national cattle herd from 77 to 100 million cattle, an increase of 30%. We also find that the current pastureland grass resource can support only 27% of the current beef supply (27 million cattle), an amount 30% smaller than prior estimates

        […]

        Taken together, an exclusively grass-fed beef cattle herd would raise the United States’ total methane emissions by approximately 8%.

          no one said they are exclusively grass fed, not that we should be doing that
