Have you ever visited a mink farm? Would you like to know more about how farmed mink are raised and cared for? Senior Truth About Fur writer Alan Herscovici asked “Les”, a third-generation Nova Scotia mink farmer, to give us a personal tour and explain the work he does during a typical year.

In Part 1: Breeding, Les explained how the mink production cycle begins early each spring. In Part 2: Whelping and Weaning, we got an insider’s view of life on the farm through one of the busiest periods, from April to June. In Part 3: Growing Up, we saw how the mink kits are vaccinated and separated into smaller groups as they grow. This time, we learn about some of the final steps in producing the high-quality mink for which Canada is known around the world.

Truth About Fur (TaF): When we last spoke, the intense work of vaccinating and separating the young kits into pairs had been completed and life on the farm was somewhat quieter as the mink grew through the summer months. What happens next?

“Les” (Nova Scotia mink farmer): As the days become shorter and the weather gets cooler in the Fall, the mink are about full grown and start putting on their winter fur. By early November we are deciding which females to keep for breeding the following Spring.

The first step is to do some blood tests. We clip the tip of a toe nail to take a few drops of blood from each mink. This is placed into a small glass tube and spun in a special centrifuge to separate the blood components.

We then extract some of the clear whitish plasma and add a drop of iodine. If rust-colored clumps appear after adding the iodine, we know that some sort of disease or infection may be present. These mink will not be kept for breeding; the data cards on their cages are marked for pelting.

TaF: So are you choosing the healthiest mink for reproduction?

Les: That’s just the first step. Then we start the most important selection, hand-grading the mink for fur quality. We are looking for a number of crucial factors, especially the velvety short-nap fur that North America is famous for. But we are also checking for the softness of the fur and consistency of colour. If there are white hairs among the brown or black fur, for example, you want to eliminate that as much as possible from your herd. This hand-grading and selection is vital. It is what determines your fur quality for years to come.

TaF: So you are selecting for health and fur quality.

Les: Yes, but we also take into account the litter size females produced, and how well they cared for their young, as well as how calm and easy to handle they are. These are all factors in deciding which females we keep for breeding the following season. And each farmer makes these decisions somewhat differently, depending on how you are trying to develop your bloodlines and fur quality for the future.

TaF: So you have balanced all these factors and decided which mink to keep for breeding. Then what?

Les: By December the mink are fully furred – we say the fur is “prime” – and it is time to euthanize the mink we will be pelting.

We wheel a special, air-tight box into the barn; it is filled with the proper concentration of bottled carbon monoxide gas. The mink are not stressed because normally it’s the feeding cart we bring through the barns.

One by one, we open the cages and place the mink into the gas-filled box. They turn around a few times, lie down peacefully, and in a few moments they are dead. Carbon monoxide is an odorless gas that acts very quickly and humanely.

TaF: And then you pelt them?

Les: Not right away. First we place them on top of the cages or onto a wire shelf, to cool thoroughly. That’s very important because the fur can be damaged if it rests too long against a solid surface while the mink are still warm. We usually send them to the pelting facility the following day.

TaF: So what do you say to activist claims that mink are skinned while they are still alive?

Les: That’s complete nonsense, like so much that the activists say about us. It’s very frustrating, for sure: we work so hard all through the year to produce the best quality mink we can raise. It’s insulting and ignorant for activists to claim that we would mistreat these animals. We are proud of how we care for our mink. Our livelihoods depend on them!

TaF: What happens at the pelting facility?

Les: The mink are pelted by experts who have the experience to do this perfectly, without damaging the fur. The fur pelt is then cleaned and put onto a special stretching form to dry slowly in the proper size and shape. This has to be done at the right temperature and humidity. The fur will then be sent to the auction facility to be graded and prepared in lots for the next auction sale.

TaF: Is only the fur used? What happens to the rest of the mink?

Les: The fat from the mink is collected to make mink oil, which is used to waterproof and protect leather, or as a fine lubricant. The carcasses and manure are usually composted to make organic fertilizers. Here in Nova Scotia we also have a pilot facility to make methane from the manure to produce electricity. In Denmark they are already producing biofuels with mink carcasses.

TaF: So let me understand this: your mink were first fed by-products from our food supply – the parts of fish, poultry and meat animals that we humans don’t eat – and then, in addition to producing beautiful fur, their manure, soiled bedding straw and carcasses produce organic fertilizers to replenish the soil?

Les: That’s right, mink help to complete the agricultural nutrient cycle, while producing one of the most beautiful, long-lasting and ultimately biodegradable clothing materials in the world!
