We pick out some popular debates in the vegan world and tackle them head-on. This time, we ask if vegans should be using animal manure


This issue we explore a slightly less contentious but equally interesting quandary: manure. We love to hear your thoughts on these debates, so please get in touch – but remember that the YES’s and NO’s are presented here simply so that all angles can be considered, we’re not advocating for one or the other, just trying to bring you both sides of the argument.


Debate: Should Vegans Use Animal Manure? 1

We’re talking crap here – fecal matter left by animals. It’s not as if somebody is farming animals exclusively for the spoils of their bowel movements, and then killing them for meat like we do with milk and dairy cows.

Manure is just animal excrement, those animals are not farmed so we can get their droppings to use for our benefit. Using manure is getting rid of animal waste products, it actively helps reduce the negative impact of animal agriculture. Animal droppings are a by-product of animal agriculture and keeping animals, and by using it as manure we’re enriching soil and using up waste in a practical way. What would we do with animal faeces if we didn’t use it for manure? Where would we put it?

To say you’re against it would surely mean you’d have to trace the source of all the plant-based food you ever eat to know whether or not manure was used to grow it. How can people realistically do that every time they eat?

Being vegan is about avoiding animal products as far as is safe and practical – trying to avoid any fruit, vegetables, or plant-based food that may have been grown using animal manure is far from practical for almost everyone.

Vegetables and fruits are washed before consumption; therefore there are technically no animal products left to consume by that point, so even items grown with manure are still vegan anyway.
For many vegans, the environmental aspect is a big consideration. Supporting the use of animal manure is an environmentally positive thing to do because it reduces waste by giving it a use. For vegans who adopt the lifestyle for ethical or moral reasons, refusing to acknowledge the positive impact of using animal manure is just blindly sticking to a list of rules without considering their real-world implications.


Debate: Should Vegans Use Animal Manure? 2

It is technically an animal product – vegans do not use animal products therefore vegans should not use it.

Using by-products of animal agriculture gives more reason for those practices and industries to exist. Using any by-products of the industry can support the arguments for its continued existence.
In some cases, animal manure can be contaminated or adulterated with other animal products – such as bone, blood, wool, or feathers. None of those would be acceptable to a vegan diet therefore manure should not be used by vegans or to grow food that vegans eat.

A University of Minnesota study from 2007 showed that certain crops were found to have accumulated antibiotics because the soil they were grown in was spread with animal manure that contained these antibiotics. Nobody, vegan or otherwise, should be consuming food laced with antibiotics.

In the same way that vegans avoid certain beers and wines because they use isinglass finings (the swim bladders of fish), vegans should also avoid products grown using manure. Neither manure nor isinglass will really be present in the end products, but it’s not just about refusing to consume animal products, it’s also about trying to remove yourself from any related practices as far as possible.

There are non-animal manures and ways to enrich the soil that are just as useful – if not more so – than animal ones. We could use green manures where crops are grown specifically to be ploughed back into the soil for enrichment. You can use clover, or seaweed, or even hops left over from growing beer; all increase the fertility of soil by adding nutrients.



We have presented you with two sides of the argument, but what do you think?

Have your say below…

    If you are vegan then I assume you are against the keeping, farming, killing, etc of animals.
    If you use the manure from any domestic animal then surely you are going against your own belief.
    How do you find where the manure has originated from, I mean you will probably find some will be collected as waste from aberttoirs, as are the bones which are used to make bonemeal.
    I can’t see how you can possibly avoid animal products 100%. Even the technology we use everyday contains animal products.

    I am a very dedicated vegan. For me, as long as i know the source of the manure and the animals are not being exploited(for example they are at a sanctuary) it seems fine to me. My dogs are vegan and I’m going to look into using their poop for manure.

    • Lachy (not vegan/not dumb) on November 13, 2018 at 12:15 pm

      what a sad life for your dog

    • Carolyn Booth on December 31, 2018 at 9:50 am

      making a dog be vegan is tantamount to animal cruelty – have a think about that…..

    • Liz Melhuish on January 9, 2019 at 9:41 am

      The whole point here I believe, is that were there not people who DO choose to consume animal products,in any form; food, clothing, feeding or nursing pets etc, there would BE no farm animals to provide the waste you so magnanimously talk of disposing of!!

    • Bert Pitt on February 2, 2019 at 4:01 am

      You are also not an animal lover because you are prepared to sacrifice your dogs to a life of misery by eliminating meat from their diets. I would not like your vet bills.

      • Allen Bradley on April 11, 2019 at 7:30 am

        One of the oldest living dogs, a border collie named Bramble lived to the age of 25 on a vegan diet. The average life expectancy of a border collie is around 14 years. I urge you too look him up.

        • C Wood on September 27, 2019 at 8:55 am

          My grandfather drank vodka and smoked cigarettes heavily, died at 98 years old. Shall we all start drinking and smoking heavily? Or 1 in a million chance of long life maybe?

        • Dan on January 14, 2020 at 11:58 am

          It’s a well researched fact that mammals fed on a restrictive diet live longer … doesn’t mean it’s in the animal’s best interest to deprive them of the nutrition nature intended.

    • The gardener! on February 17, 2019 at 10:41 am

      How can you be vegan and then keep an animal as a pet for your own benefit, is that not exploiting dogs? Unless you let it run free and go where it wants when it wants. That’s animal cruelty. On a side note making a dog vegan is cruel as they don’t have the digestive system to take large quantities of plant matter unlike a human, surely it’s tge dogs choice what it eats like it’s you choice to choose what you eat?

      • Helge. on October 24, 2020 at 3:29 am

        Actually, unless your dog does get to run around and kill/eat whatever it wants, forcibly restricting its diet is the secondary form of cruelty, next to supporting the parasitic breeding, domestication and imprisonment of animals by ‘owning’ them. So A+ for vegan dog owner up there.

    • Tiger Tomcat on March 18, 2019 at 3:45 am

      Soo you’re committing animal cruelty by having your dogs on a “Vegan” diet. DOGS ARE CARNIVOROUS!!!

      • Dan on January 14, 2020 at 11:59 am

        Dogs are omnivorous … they are scavengers by nature. However, they are ‘intended’ to eat a varied diet, so removing meat from their diet without their consent is, IMO, cruelty.

    • Allen Hunter on March 19, 2019 at 2:37 am

      Carnivore feces does almost nothing to enrich soil…

    • Rachel on April 10, 2019 at 11:46 pm

      In some countries, such as Kenya, rabbits are kept (in cages) specifically for their waste products to be used as fertiliser. But I don’t know how as a vegan you can delve this deeply. I only know this because I work there.

    • Vetusto on April 17, 2019 at 1:28 pm

      Do you really believe that using manure from animal sanctuaries does cover the fertilizing demand of the crops that should feed the population? You are a daydreamer!

    • Peter Capofreddi on November 15, 2019 at 10:32 pm

      Our dog is vegan and she is much healthier than on diet including meat. Claim that dogs require meat is false. With the cat that’s another story.

      • Dan on January 14, 2020 at 12:00 pm

        If she’s not a diet containing meat, how do you know she’s any healthier?

  4. will on March 22, 2018 at 12:43 pm

    Veganism is an unsustainable first world luxury reliant on a complex deliverance system. Take away fossil fuel transport taking goods from 3rd world countries and synthetic fertilisers and you’re left eating a turnip most days of winter, and dying of some deficiency.

    Using animal manures from the food industry (40% of all food grown on them) is not ‘reducing waste’ because there is none, it is hypocrisy. How can you morally disapprove with the very industry that provides with the means to be able to eat? You can’t.

    There are no non-animal ‘green’ manure alternatives available in any useful quantity that could begin to meet the volume needed to replace manure.

    • Stephen Nitschke on April 11, 2018 at 11:55 am

      What isn’t an unsustainable first world luxury? You make no compelling arguments against veganism. There are many ‘green’ manure alternatives, and there are farms which don’t use manure. What veganism is is an experiment in the evolution of the human race.

      • dawdawdwa on March 24, 2019 at 9:00 am

        well said Stephen Nitschke

      • Theresa on March 31, 2019 at 12:30 am

        Yes it is, it’s an experiment of pseudo-science gone wrong. Humans evolved to eat meat. You can’t devolve them into not eating meat or animal bi-products. No matter how much you try to validate your malnourished diet, farmers will never care about what you don’t buy in an attempt to end animal cruelty. It’s their responsibility at the end of the day, and they will answer to their Maker. But don’t think your little “vote” of groceries matter. It doesn’t. They won’t change because you decide to malnourish yourself in idiotic protest. Btw, I was an ethical vegan for a year and I now eat a standard diet. The first time I ate meat in a year I could feel the blood flow back into my face like I breathed my first breath of life. Let me tell you, you have no idea what you’re doing to your body denying all those food groups.

        • Tim Spencer on September 29, 2019 at 7:44 pm

          You’re so full of it. You were never vegan. I’m so sick of hearing the “I was vegan for a year and got sick so I then ate meat again and felt great”. BS. Lying. I have been Vegan for 5 years now. All of my blood tests are better now than they were in my 20’s. I’m healthier now and according to major studies for all-cause mortality, a whole-food plant-based diet prevents nearly all of the major age-related diseases that cause early death. Humans are not only able to be vegan, but we are far more healthy as vegans than omnivores. The evidence is overwhelming.

          • FrankieBoiledEgg on September 28, 2020 at 4:05 pm

            I’m going to start off by saying I don’t think you’re stupid for being vegan like so many people do here, in fact I applaud your efforts, I don’t have the willpower to give up meat and by products because I enioy them far too much.


            This phrase vegans and vegetarians use – plant based – would surely imply that you ingest other forms of nutrition into your body such as meats and animal products. Therefore, as a meat eater I would say that I have a plant based diet simply because the majority of my diet are fruits and vegetables.
            I don’t think veganism/vegetarianism is sustainable simply because your body does miss out of vast amounts of important nutrients such as B12 as well as in some cases vitamin D.

            Some areas of farming and animal cruelty are shockingly awful but not all, therefore to stop animal cruelty I would suggest you look into buying your produce from farmers directly or paying more attention at the shops to where meats and by products have been sourced from. I say this knowing some people will call me a liar and give examples of calves being “ripped” from their mother’s at birth but that is really only the case in America and other countries that don’t have animal cruelty laws like we do in the UK.

            Your fight is with the lawmakers and their policies on animals, not with the people who just want to have a steak at the end of a long day.

      • Dan on January 14, 2020 at 12:02 pm

        You cannot survive a vegan diet with vitamin B12 supplementation, and Vegans have a 20% higher risk of stroke.

        If the all of humanity went vegan we would need to grow about ten times the soy that we do now, since the only plant source of one of the essential amino acids (for adults) is soy … there are essential amino acids for children that ONLY come from animal produce.

  5. Russell Booth on April 26, 2018 at 12:42 am

    It looks like the woman I’m going to marry is a vegan.

    I started asking myself the question, can we still be classed as vegans (because she most likely wouldn’t want me to eat something that was once live creature) if I use chicken manure from the local farms ?

    The chickens are slaughtered for human consumption that are from the farms I’m talking about,so far, the answer I’ve found has been no !!!!

    I’m going to grow my own fruit & vegetables so I’m looking for a way to fertilize the plants,so far,the only way that I can practically do it is how my late grandfather did it on his old banana farm – with a chemical fertilizer.

    My other question which I’ve been asking myself is can I use pesticides & still be classed as a vegan ?

    For example, even if the pesticide was organic,it seems like the produce wouldn’t be classed as vegan if it involves killing pests such as slugs,snails, caterpillars & the cabbage moth.

    Yet many vegans buy their fruit & vegetables from a supermarket or greengrocer where they have been sprayed with an insecticide.

    How far do you go to the point of not being classed as a vegan ?

  6. Alice Brown on June 22, 2018 at 6:24 pm

    The Lowly Worm

    All compost piles rely on animal life to break down the material put in whether it comes from animals or from plants. Worms, maggots and the other creepy crawlers who do most of the composting even in a home garden are animals. They are digesting the material and turning it into worm poop. Even if worms aren’t introduced they will be there and what you are getting from your compost pile is largely the excrement left behind by these very small animals. Even composted vegetable matter has worm manure or castings. If the garden soil is healthy nothing will able to keep those creepy crawlers out. They are tunneling around the garden leaving their feces behind.
    Is it ethical and vegan to use the manure if the animals are so small and discreet that it’s easy to forget they are even there and what they really do for us?
    I think we should all give the worm the credit that it deserves even though it is part of the animal kingdom. Soil with out some animal life would be dead and would not grow nutrient rich plants.

    • uno on January 9, 2019 at 3:20 am

      dumbass we aren’t farming and harming the worms. that was the whole point of not using the manure, that and worms don’t have antibiotics

      • Not vegan but interested on July 23, 2019 at 10:52 am

        Am thinking of getting some indian runner ducks in order to convert our garden pests into fertiliser. From reading this page it seems that the primary moral issue with this is keeping animals for my own benefit (in this case their manure is pretty central to the point, rather than being the by-product of another industry). I’m curious as to how much of a bearing the ducks’ quality of life has on the matter, or whether I’ll burn in hell for so much as entertaining the idea. Thoughts appreciated…

      • FrankieBoiledEgg on September 28, 2020 at 4:09 pm

        No need for name calling, their comment is posed not as a serious interjection but as a thought experiment in this debate. The question is how far down the chain do you have to go for something to be Vegan?

    • Organic Pig Man on February 18, 2020 at 8:53 am

      Alice Browns comment is exactly why veganism is a false claim of superiority based on the assumption that they do not kill anything to eat food daily. the vegan moto is, to not exploit any living animal in the persuit of food. As Alice Brown rightfully says, there would be no food without the micro organisms from worms to protazoa. All eating and killing each other. Then the plough comes along and kills many millions more when harvesting vegetables. The fact is that no one can claim to be a vegan based on the ideology that no animals are exploited. Those animal sanctuaries may extend the life of the farm animals it recovers but at what cost. Farm animals are bred to live short lives and will suffer from old age ailments they would never have if in the food industry. So is it cruel to extend the life of a farm animal for personal emotional based reasoning, because vegans cant accept that this cruel world was designed on a kill or be killed basis.

    Plant based fertilizer. Enough said.

    • Tiger Tomcat on March 18, 2019 at 4:01 am

      You do know that manure is higher in Nitrogen then any plant based fertilizer.

  8. Bert on September 2, 2018 at 11:21 am

    Plant based fertiliser broken down by animals.
    Or are vegans sizeist so a small person is worth less than a big person of you extrapolate this line of thinking. Time to eat lots of Donuts I reckon

    • Ryan on November 30, 2019 at 3:58 pm

      And where does the nitrogen come from?

  9. Cristina on October 6, 2018 at 5:01 am

    Okay thank god it’s still vegan as long as we wash it…. Now I understand why unwashed fruit can give you pesticides.

    • FrankieBoiledEgg on September 28, 2020 at 4:11 pm

      What do you mean “can give you pesticides”? Pesticides aren’t a disease you can catch.

  10. Amanda McKinney on October 15, 2018 at 9:56 pm

    I have a small herd of rescued horses and mules. If they need meds or wormer, their manure goes away for several days after. But they are eating organic most of the time, and that manure goes back to the earth. That includes my garden, where I use their manure to grow carrots for them, among other things. Heck, they are fertillizing and reseeding their own fields. These animals have to have a safe home, should I turn their waste into actual waste, or use it to help feed them, me and my husband, neighbors, etc? (That’s a rhetorical question; I’m going to keep doing what I’m doing).

  11. Susan on February 6, 2019 at 1:26 pm

    I have two elderly horses they eat nothing from other animals as they are vegan. I have to collect their manure from stable and field as not good to leave it.
    So it rots down in an organic heap and i use around fruit trees and roses. Cannot see this is non vegan. The are just giving back what I fed them ☺

  12. Ben on June 17, 2019 at 1:46 am

    I’m all for vegans using animal manure. Greater demand for manure means the need for more tasty animals to poop that brown gold. More animals pooping means a glut on the market of said tasty animals. Tasty animal prices go down… Omnivores rejoice.

  13. Simon on November 3, 2019 at 11:13 am

    It’s as simple as this: if you’re vegetarian, pesky or vegan (or truly claim to be) then you shouldn’t support the use of animal products.

    A large proportion of fruits and vegetables are grown using the old favourites feather, blood and bone or manure. One reason the the meat industry is incredibly lucrative because all of the waste products created can be sold on to create fertilisers. So, unless you’re growing your own fruits and vegetables, you can be fairly certain that you’re directly supporting the meat industry.

    This means that 90% of people who claim to be pesky, vegan or vegetarian are no better than the rest of us (despite acting like it).

  14. Joe on February 25, 2020 at 11:54 pm

    I am not vegan & I use manure from animals I do not own,nor keep, because it helps the animal owner keep the animal’s pins clean & I am an organic gardener. There can be no large scale organic garden cycle with out animals. Totally plant based gardening/ cycle are not found any where in nature without animal inter action.

  15. nico david on August 20, 2020 at 11:17 am

    lol the angry animal abusers always come out on these threads to attack in any way they can. at least vegans are TRYING to REDUCE the suffering we inflict on animals. its not a vegan world and its not always possible, but instead of attacking people for trying to lessen their impact on animals why don’t you give it a go yourself. manure from an animal sanctuary i think is a great idea, but from a factory farm, hell no.

  16. Helge on October 24, 2020 at 3:43 am

    How far down the chain does veganism go? Bees are a common example, but what about wasps, spiders, worms, birds, rats, mice, etc? They disperse pollen and seeds not entirely unlike bees pollinate. How small can you go? Is washing your hands immoral? Killing mosquitos? Bats get a lot of their diet from small insects. Flies? They digest *ick* rotting animals and plants alike, but should they be ‘catch and release?’

  17. Joseph Hammond on March 24, 2021 at 2:07 am

    Nicole David. This is a valid issue. You do not try to be a vegan you either, Benifit from and there for support, or do not benefit from and therefore do not support the meat industry. As a vegan or vegetarian you are attempting to prove that animals are not required to sustain humanity in order to prevent there suffering. If an animal product is used to make something you eat or use, that was taken from an animal who’s only existence is for it to be killed for meat than you contribute to that animals suffering.
