The other assumption I’d like to challenge is that welfare reforms would lead to “slightly less horrible though still pretty bad factory farms” and that they have serious limitations.
I think that welfare reforms lead to big changes in welfare. How much chicken welfare reforms help chickens have been researched in detail by the welfare footprint project and summarized in these graphs:
In this spreadsheet, I estimated that if we assume that hurtful pain is 15 times worse than annoying, disabling pain is 100 times worse than annoying, and excruciating pain is 500 times worse than annoying, then broiler reforms avert 50% of suffering, switch from conventional to cage-free averts 60% of suffering, and a switch from enriched to cage-free averts 36% of suffering. That’s a lot. If you don’t like those subjective values, you can enter different ones but the situation doesn’t change drastically when I enter different values. And these are only current efforts. Eventually, we may improve conditions even further. Since chickens are something like 75% of farmed land food animals alive at any time, these are very significant changes.
Yes, enforcement can be an issue, but these campaigns seem to help many animals per dollar even when enforcement concerns are taken into consideration. And yes, watering down sometimes happens, but sometimes it doesn’t. Broiler commitments seemed to be doing well in the EU last time I checked, and most cage-free commitments with a due date in the past have been fulfilled. We don’t make 100% shots we take but that doesn’t happen in any animal welfare field. And we do make most of the shots we take.
Another way of putting this is that these corporate welfare reforms are about half as good as preventing their births, or better, for their welfare. So, corporate welfare reforms over a region (a country, a US state, a province, the EU, a continent, the world, etc.) would be as good as cutting present and future factory farming in that region in half or better (in welfarist terms, ignoring other effects, assuming no new lower standard farms under the reform scenario, etc.).
Thanks for this Saulius. This is a slightly positive update for me that both cage free and broiler reforms are more impactful than I thought.
One concern I have with the Welfare Footprint study (caveat: I have no experience in animal welfare science or with the BCC). The Welfare Footprint study people say (bolding added by me):
We analyzed the following scenarios, for which data on broiler welfare was available: (1) a baseline scenario represented by the use of conventional fast-growing breeds (e.g., Aviagen Ross 308, 708, Cobb 500) reaching a slaughter weight of 2.5 Kg at 42 days and (2) a reformed scenario, represented by the use of a slower-growing strain (ADG: 45-46 g/day), reaching the same slaughter weight in 56 days. This is a growth rate consistent with typical figures achieved by various of the breeds approved under the BCC, also referred to as medium- or intermediate-growing broilers, also falling within the acceptability of other welfare certification schemes.
My concern is with the claim that reaching 2.5kg in 56 days necessarily is the growth rate experienced by BCC chickens, or whether the final BCC birds are actually faster growing.
Given the watering down concerns Farm Forward discussed, and that I wasn’t sure how up to date WF’s study was, I looked into the different breeds accepted by the BCC (you can see the latest breeds GAP approved here) and how long they take reach WF’s cited slaughter weight of 2.5kg.
Of the 11 breeds GAP approves, 2 of them (Aviagen Ranger Classic and Aviagen Ranger) reach 2.5kg below significantly below the 56 days benchmark WF uses (they reach 2.5kg at 50 and 51 days, respectively). 5 to 6 days may not seem like much, but remember we’re only talking about a difference between 14 days (difference between reaching 2.5kg at 42 vs 56 days) that accounts for half the suffering these animals experience. The other breeds were either around 56 days to reach 2.5kg, or in the case of the Hubbard Redbro significantly above it.
Worst case scenario then, if you just use average weight gain as a simple welfare proxy then I estimate these BCC approved breeds to be half as less bad off as Saulius estimates.
I find this concerning because 1) companies will likely congregate to the fastest growing breeds still available, and 2) it possibly illustrates the watering down concern.
This sounds like a legitimate concern that I don’t remember seeing raised elsewhere. Thanks for raising it! We’ll pass it along to the Welfare Footprint Project.
This is indeed a legitimate concern. We do not have accurate information on the distribution of BCC-approved breeds used in the committments made so far, but I believe that organizations working on and monitoring the committments (possibly the Humane League and CIWF, which publishes the Chicken Track), are likely to have this information. From statements of company’s representatives, it seems that the Hubbard breeds are prevailing in Europe, see e.g. this statement: “In Europe, where the issue of breed is more advanced than in the U.S., the Hubbard JA757, JA787 and Redbro are the main breeds used for the BCC market”.
It may be interesting to know though that an experiment published recently, which used Avian Ranger Classic (the fastest growing of the Aviagen breeds), consistently showed various welfare benefits associated with this slower-growing breed, even when it was raised in higher stocking densities than the conventional fast-growing breeds (showing that it is better to be this slower-growing breed in high densities than a fast-growing breed in low densities).
If also useful: our estimates are very conservative, and represent what we estimate to be the minimum time in pain averted with the reform. In this chapter (table 1), there is a list of welfare harms excluded from analysis, which if considered should increase further the estimated benefits of the transition to slower growing breeds.
I’m afraid that I don’t remember anymore. You can reach out to the Welfare Footprint Project directly about this if this is decision-relevant to you. If you do that, updating with their answer here would be useful as I would like to know this too.
I should also point out that at least for the laying hens, the Welfare Footprint Project strived to be conservative in their assumptions so as not to inflate the benefits of reforms. You can read about the exact ways they were conservative it in chapter 9, starting with “The empirical estimates presented here are conservative” on page 10. I haven’t examined the book on broilers but I assume that the same approach was taken.
Thanks so much for sharing this analysis Saulius. I wasn’t familiar with these numbers, and admittedly also weakly held the uninformed view that corporate welfare reforms had limited impact on the welfare of farmed animals. However, I’m curious to know, have any other non-industry aligned animal welfare experts expressed their opinions about the welfare footprint project’s estimates?
Good question. I don’t know. But I can tell that the review process seems to be legitimate. I’ve just googled all the people they thank for comments and suggestions for the laying hen report in the acknowledgements. Some people seem like they should be qualified: Kaitlin Wurtz (PhD in animal science, worked as a farm inspector for laying hens), Ivelisse Robles (PhD in animal behaviour and welfare), Elsa Negro Calduch (Doctor of Veterinary Medicine), maybe Andrew Rowan. I couldn’t find info on some other reviewers. But I don’t know how deeply any of them reviewed it.
Recently, I was managing Michael St. Jules when he was reviewing (for the second time) their book on laying hens and I also expressed some concerns to the Welfare Footprint Project myself. I can say that they were very responsive to our comments, gave comprehensive answers (that convinced me to drop my concerns for whatever that’s worth) and encouraged more comments, despite the fact that they had moved on from focusing on layer hens at that point. I know that they also are keen to get reviews on their broiler work too and were offering to pay certain people for their reviews.
Last point on this: Even if the animals impacted by these reforms suffer only have as much, that’s still thousands of hours of equivalent annoyance level suffering per animals (per your spreadsheet). Though this takes nothing away from the good done by these reforms, to me this still qualifies as pretty horrible factory farming.
We should be happy by the progress we have made, but there is still a long road ahead.
All in all I’m now thinking that switching from battery cage to cage free averts ~60% of suffering (per your figures), and switching from conventional to BCC-approved broilers averts 30-40% (your figures plus a downward estimate for the breeds growth rate concern I mention in the other comment).
