| > practically all other domesticated animals are more efficient than beef on a per-calorie basis yes, this is true, although some of those, like chickens which you mentioned, or pigs that are mentioned in the link you shared, are dependent on grains - unlike beef, which can be grass-fed. But there are more animals besides beef that can be grass-fed, and they might be more efficient than beef. It would be interesting to know the feed conversion ratios of goats and sheep for example. The problem of goats and sheep is that, in a regenerative faming context, their manure is not perceived to be as effective as cow manure. For this reason, would be interesting to measure both feed conversion ratios AND manure production ratio. Knowing the effectiveness of manure in a regenerative farming context is very important, unless we want to continue depending on fertilisers made from petroleum which is just as bad as burning gasoline in terms of global warming. |
