Down and Silk: Birds and Insects Exploited for Feathers and Fabric

Each year, the down and silk industries exploit millions of geese, ducks, silkworms, spiders, and other animals, causing unnecessary pain and suffering to these feeling beings.

Geese and Ducks Suffer for Down
Down is the soft layer of feathers closest to birds’ skin, primarily in the chest region. These feathers are highly valued because they do not have quills. Most products labeled “down” contain a combination of these underfeathers and other feathers or fillers.

Most down comes from birds who are victims of the meat and foie gras industries. Ducks and geese often have their throats cut and are then scalded in hot water to remove large feathers.(1) Sometimes, the birds are still conscious when they are dumped into the tanks of hot water.

In addition to obtaining down from slaughtered birds, a large amount of down is torn from the bodies of birds who are still alive. PETA obtained undercover video footage of workers in Hungary (one of the world’s largest producers of down) pulling handfuls of feathers from geese so violently that the birds’ skin ripped open, leaving them with gaping wounds that the workers crudely sewed back together without using any anesthetics. One worker was photographed sitting on a goose’s neck to prevent her from escaping during the procedure. Up to 5 ounces of feathers and down are pulled from each bird every six weeks from the time they are 10 weeks old until they are up to 4 years old.(2) Plucking birds causes them considerable pain and distress. One study of chickens’ heart rates and behavior determined that “feather removal is likely to be painful to the bird(s),” and another study found that the blood glucose level of some geese nearly doubled (a symptom of severe stress) during plucking.(3,4)

Buying down also supports foie gras production, in which ducks and geese have tubes forced down their throats and grain and fat pumped into their stomachs until their livers become diseased and enlarged. The birds are slaughtered, and their livers are sold as a “delicacy.” Many foie gras producers supplement their income by selling the birds’ feathers. Please read our factsheet on the foie gras industry for more information.

Silk Production Causes Painful Death for Insects
The so-called “silkworm” is actually a domesticated insect who, in nature, goes through the same stages of metamorphosis—egg, larva, pupa, and adult—that all moths do.(5) Silk is derived from the cocoons of larvae, so most of the insects raised by the industry don’t live past the pupa stage, as they are steamed or gassed alive in their cocoons.(6) Approximately 3,000 silkworms are killed to make every pound of silk.(7)
 
Pharmaceutical companies have taken an interest in these insects, too, because they are perceived as inexpensive and easy to raise and can be genetically engineered to produce silk that contains human collagen.(8) Silkworms have also been transgenically modified to spin fluorescent-colored silk.(9)

The military and medical communities have been testing on spiders, hoping to harness the strength and flexibility of spider silk for suture thread and to create a fabric that could replace Kevlar.(10) If they are kept together in captivity, however, spiders succumb to stress-induced cannibalism. Approximately 1,400 spiders are needed to spin 1 ounce of silk, so farming spiders has not been a profitable venture.(11) Instead, scientists have experimented on goats by inserting spider-silk genes into their cells, causing the goats to produce milk that contains silk proteins.(12) The military continues to fund this research, even though it has yet to produce a product that is commercially viable (it takes 600 gallons of milk to produce a single bulletproof vest).(13)

What You Can Do
Don’t buy silk or down items. Apart from the cruelty involved in its production, down is expensive and becomes useless when wet—unlike cruelty-free synthetic fillers such as PrimaLoft® and Thinsulate™, which retain their insulating capabilities in all weather.(14)

Warm, cruelty-free bedding and winter clothing are widely available at stores such as JCPenney, Target, and The Company Store.

Humane alternatives to silk include nylon, polyester, Tencel, milkweed seed-pod fibers, silk-cotton tree filaments, and rayon.
