Boar Taint

“Boar Taint” is a urine and/or fecal like smell/flavor that can be present in the fat of in-tact male pigs, aka boars, when cooked.  

💩

There are 2 main ingredients to “boar taint”: Androstenone and Skatole.  Androstenone is a sex pheromone that begins to accumulate in the fat of boars once they reach maturity.  Skatole is a digestive by-product formed in the intestines, also accumulating in fat.  There are many factors that contribute to the levels of androstenone and skatole, such as age, genetics, season, feed and feed availability, environmental cleanliness, and the presence of sexually receptive females.  I’ll touch a little on each of these.  *This is simply information, not intended to scare you. 

❤️

Roughly only 20% of boars exhibit boar taint and about 75% of humans can detect it.  The risk is low, but for those who can taste it, if you happen to get one of the 20% with boar taint, it is completely repulsive, and most likely, inedible.  Research suggests women are more susceptible to boar taint, but my personal experience is the opposite.  The people I have met most sensitive to boar taint have all ironically been men, with women of the same household unaffected.  You can also develop a sensitivity to boar taint with age.  The more exposure you have to boar taint, the more likely you are to notice it.

Most boars reach maturity between 6-8 months of age, with slower growing breeds, such as kunekune, closer to the 12 month mark.  The risk of boar taint cannot be completely eliminated by slaughtering boar pigs before they reach puberty, but it definitely lowers it. 

🐽

Boar taint has been recorded higher in darker colored pigs, with Durocs at the top of the list.  Boar taint could be controlled with genetic selection, but this would also directly effect feed conversion rates, reproductive and growth performance, and not just in males, which is why boar taint has not been effectively bred out (if that were even achievable).  There has been some indefinite research suggesting lower risk of boar taint in lighter colored breeds such as Landrace, Yorkshire, Chester, and Gloucestershire Old Spots.  However, there isn’t a lot of foundation to those claims, so I take it with a grain of salt.  

🧂

With androstenone being a sex pheromone, it is no surprise there is a seasonal pattern.  Androstenone levels are FIVE times higher from October through December.  So if you are raising out boars for meat, keep this in mind when choosing your butcher date.  I can confirm my own boar has started getting busy just in the last week.  I’m dying for some baby pigs, so I’ve been cheering him along like his biggest fan.

Since skatole accumulates in the gut, there are some things we can do to lower those levels with diet.  High fiber diets have been shown to reduce skatole absorption rates.  Continuous feeding 15% fiber-rich chicory for 3–4 days before slaughter was sufficient to reduce skatole by 50–60%.  When this was done for 2 weeks, it was completely eliminated.  

🤯

 *Availability and cost of chicory could be pricey, growing it could be an alternative solution.

The abundance of food is also a factor.  Boars free fed will be less likely to exhibit boar taint at the butcher shop.  On the flip side, excessive protein can lead to HIGHER skatole levels.  This can be avoided by practising phase feeding, which varies the level of protein throughout the animal’s growth.

Skatole can be absorbed through skin contact or re-ingestion of feces.  This is very simply avoided by providing a clean area for your boars.  Pigs are ironically very hygienic on their own and typically defecate in one spot, so this *should be* an easy task.  If your pigs are on pasture, rotating pastures might be necessary. 

🌱

The presence of sexually receptive females stimulates a rapid rise in androstenone concentrations in boars.  Growing boars with female pigs can also increase the intensity of odor in boar fat.  Keep in mind, males can sense females in heat, so keeping them separate is only effective if they are housed fairly far away from each other or hard barriers are in place.  Nobody likes mending fences and chasing pigs.  I would also be weary of keeping more than a few adult boars together, as they could begin fighting for food.  If you are raising boars for butcher with gilts, you might consider separation or processing before the gilts first heat cycle to reduce your risk of boar taint. 

🥓

So why raise boars at all?  If you are breeding, you simply can’t avoid it unless you are utilizing aritificial insemination.  Literature is consistent: boars are up to 32% more feed efficient than castrated male pigs, aka barrows, and will dress out much leaner than barrows on the same diet.  Barrows can thrive on lower quality diets, not that I am encouraging it, but it could help offset their lower feed efficiency rates.  

💰

Some people will argue ethics of castration.  I am not some people.  Castration is the answer to avoid boar taint all together.  It is ideal to castrate between 1-3 weeks of age.  The smaller they are, the easier this will be on you, if you are performing the castration yourself.  Vets can castrate pigs at any age under anesthesia, so if you have an older boar that’s being retired to the freezer, this is something you can do a few months prior to processing if taint is a concern.  Since pig testicles do not hang down like ruminants, banding is not an option.  And since it came up recently, pig vasectomies do not exist.  Testicles must be removed entirely to produce a barrow.

It is important to also note that boar taint is only evident when pork is heated.  So if you already have a smelly pig on the chopping block, he would be an excellent candidate for charcuterie, since no heat is required.  

🍖

The addition of spices can help in masking boar taint.  Cutting a boar into sausage is a good choice as well.  We recently just added chorizo to the menu, giving you FIVE different flavors of sausage so you don’t get bored with just one.

*I can not 100% guarantee you won’t still notice some boar taint even in sausage, as that will be heavily dependent on your sensitivity to it and the intensity of the taint.

Which means it is this cut’s moment to shine- The Oxtail.  

🐂

Oxtail is simply the tail from cattle.  Back in the day, oxtail came from the tail of an “Ox” i.e., a male, steer, trained to work on the farm, hence the name Oxtail.  It is now sourced from either sex, because, equal rights and all.  

🚹
🚺

I like to cut oxtail into 2” long oval portions, which is an ideal size for braising and slow cooking to cook the meat, but also an ideal size to maximize the release of the bone marrow, fats, and gelatinous collagen. 

🍲

I would LOVE to see your favorite ways to cook oxtail in the comments!

Cured meats are preserved by the addition of salt, with the aim of drawing moisture out of the food by the process of osmosis.  Because curing increases the solute concentration in the food and hence decreases its water potential, the food becomes inhospitable for the microbe growth that causes food spoilage. Curing can be traced back to antiquity, and was the primary method of preserving meat and fish until the late 19th century.  Dehydration was the earliest form of food curing.  Many curing processes also involve smoking, spicing, cooking, or the addition of combinations of sugar, nitrate, and nitrite.  The most common cured meats includes bacon, ham, salami, corned beef, kielbasa, blood sausage, andouille, pepperoni, pastrami, bologna, and prosciutto.

Aging is a process of preparing meat for consumption by letting the meat rest in temperatures just above freezing in order to break down the connective tissue within the meat.  The two methods of aging meat are wet and dry aging.  It is also the same process that occurs in meat that is “hung” in refrigeration.

To simplify, curing is a form of preserving meat and aging is like reverse rigor mortis, a form of tenderizing.

I see a lot of folks using these terms interchangeably.  I hope this helps!

Whatever you call it, it’s a cool little semi-circle weaved with a web of intramuscular fat that sits inside the hip on the Aitch bone, and there are only two of these babies per beef.  It’s small, flavourful thanks to it’s natural marbling and easy to prepare with a quick pan sear.

This fabulous steak will be making its way to our new cut sheet for 2023 along with some other exciting new options!

PORK SIRLOIN

I didn’t realize so few people have experienced a pork sirloin!! 

🤯

Pork sirloin is tender and full of flavor, but lacking in the fat department, so be careful not to overcook these beauties!

The pork sirloin is located near the tail end of your pork loin (pork chops), with typically just 3 steaks per side.  Smaller breeds may have less, but that’s ok- it can also be made into a small roast if there isn’t enough to cut a couple steaks out of!  Sirloins and sirloin roasts can be prepared bone-in or boneless.  I prefer to cut them boneless, because the bones can be a little wonky.  

🤪

Preparing them is easy!  For steaks, treat it as you would a pork chop.  You can easily avoid creating a dry, tough piece of meat by using your meat thermometer 

🌡

.  Safe internal temperature for pork is 145 degrees.  Keep in mind, your meat will continue to cook once you remove it from your grill/oven/skillet/magic cooking device/etc.  If opting for a sirloin roast, consider wrapping in caul fat for additional deliciousness.  

🤤

I’m often asked about what breeds I think are best (for meat).  My response is always the same- they are all edible.  What your goals and priorities are, however, will help you decide on a breed. 

I’m going to talk about pigs, because it is perfect pig buying weather!  Pigs are a bit easier to raise in colder months, imo. 

If what you need is something with the quickest turnaround- look no further than some of the more popular breeds such as Duroc, Berkshire, Hampshire, Chester, Landrace, Yorkshire, Poland China, and/or any cross in between.  Hereford pigs are also growing in popularity.  These breeds will reach maturity within 6-8mo.  I would not rely on these breeds to live on pasture. I have personally used these breeds when I had lots of free scraps from restaurants, which they love.  However, if you do not have this available, you’ll be looking at buying bagged feed. 

If you have a bit more time, you might look into some heritage breeds such as Kunekune, American Guinea Hog, Idaho Pasture Pig, Gloucestershire Old Spot, Meishan, Mangalitsa, Red Wattle, Tamworth, and Large Black.  Most of the breeds mentioned here are considered to be a ‘Lard Pig’.  This means they will produce a large amount of fat, if allowed to eat a diet heavy in fatty food.  But just as someone can raise a fat Yorkshire, a lean Kunekune is attainable as well, if given a breed-appropriate diet.  Most of these breeds will take close to a year (or longer) to reach maturity, with Kunekune and AGH among the smallest and GOS and Large Black among the largest.  These breeds are best suited on pasture, supplemented with hay in the winter. 

I highly recommend doing some research on your breed and working with a reputable breeder for stock.  Each breed has different needs and will have different characteristics that will help you choose what is best suited to your situation.  Define what your goals are with pigs and picking a breed will become a lot clearer. 

Things to consider:
-Fencing availability
-Feed availability
-Mothering instincts
-Temperament
-Purchase Price
-Size
-Foraging Ability
-Growth Rate
-Meat Preference

Most butchers book out months (or years) in advance!  So if you don’t want to pay for any unnecessary extra feeding, you’ll need to plan this part out long before your animal is “ready” for butcher.

Generally speaking, butchering just around maturity is ideal for most animals.  You utilize the full size of the animal, at it’s younger point in life for more tender meat (and less investment). 

Your first place of reference is your breeder.  Whomever you purchased that animal from likely has experience with that breed, specifically that blood line, can tell you approximately when they’ll reach maturity. 

If you did not buy your animal from a breeder, you’ll be basing it off of breed standards and how you intend to feed it.  Keep in mind, animal growth time will be higher in grain fed animals and slower in grass fed animals.

Don’t know your breed?  Ask.  There are so many resources here on social media and local to you that will help you determine what you have and approximately when it should reach maturity. 

However, you may find yourself with an animal that isn’t in that “ideal” age range to butcher that you still need to send to freezer camp.  I’m here with a little secret: they are all edible. 

The reality is, when to butcher is entirely based on your needs and preference.  You can butcher a suckling pig just as you can butcher a 5yr old sow at 600lbs.  Are these going to yield two completely different products?  Of course they are.  Are they both valuable protein?  Of course they are. 

Whether it’s your sons first show critter perfectly timed for a butcher date, an old breeder that no longer serves you, or just an asshole escape artist that needs to go, we’re here to help time your butcher date perfectly for you!

Steak Breakdown:

Pictured is the T-Bone Steak & Porterhouse Steak.  Both consist of the NY Strip on one side of the bone (the spine) and the Tenderloin, also known as Filet Mignon when cut, on the other side.  The difference between the two is where the cut comes from.  The Tenderloin is tapered, so cuts towards the head will result in a smaller portion of the Tenderloin on the steak (T-Bone), and cuts towards the tail will include larger portions of Tenderloin on the steak (Porterhouse). 

When you’re filling out a cut sheet, this is why the option is T-Bones & Porterhouses OR NY Strips & Filets. 

Caul Fat

Did I butcher an animal for you?  Did you receive back a little bag marked “Caul Fat”?  Are you as confused as ever?  Let me explain!

Caul fat goes by many different names; its technical name is the “greater omentum,” but it can also be referred to as fat netting, mesentery, lace fat, crépine (French), or ragnatela (Italian).  While it doesn’t make a great fat for rendering or cooking, like kidney fat (lard) or back fat, it’s perfect for wrapping pâtés, meatloaf, meatballs, sausages, or roasts to keep them moist while they cook. 

Caul Fat can withstand high temperatures.  During cooking, the caul fat slowly renders out, basting the meat with fat, keeping it from drying out, and adding an extra layer of richness.  Despite the fact that it surrounds the digestive organs, caul fat doesn’t have an unpleasant or “organy” flavor at all.
