The boom in heritage turkeys

I sent my post asking what is behind rocketing turkey numbers to DAD-Net and received this interesting comment from Marjorie Bender, Research & Technical Program Director, American Livestock Breeds Conservancy, which she kindly agreed to share here:

The growth is reported as occurring in the US, but the reported numbers are much larger than make sense to me.

The American Livestock Breeds Conservancy has been actively researching and promoting non-industrial, naturally mating turkey varieties for over 10 years. ALBC has periodically censused this population. In 1997 the breeding population (male and female) of naturally mating turkeys was 1335. In 2003, the breeding population had more than tripled, rising to 4412. In 2006, the population had more than doubled again, reaching a total of 10,404 breeding birds.

I don’t know where their numbers came from, or how they are counting. ALBC counts breeding stock, not number of head raised.

In 1997 ALBC initiated some research on the health of the immune systems of several varieties of naturally mating turkeys and an industrial strain. The naturally mating turkeys had a significantly more robust immune system. At about the same time Slow Food USA contacted ALBC about getting ‘heritage turkeys’ on their members’ dining tables. We provided them with contacts for hatcheries and breeders and they linked them up with consumers. The main food editor at the New York Times taste-tested several and LOVED them. She wrote a wonderful article raving about them. People started looking for Heritage Turkeys, and folks started raising them but with trouble. ALBC developed a production manual and workshop — How to Raise Heritage Turkeys on Pasture — which has educated a number of people. ALBC also conducted breeder selection clinics to improve the quality of the varieties – most of which had suffered from lack of selection of the decades. The market has continued to grow, as has the motivation to produce these.

Thanks, Marjorie.

And W. Stephen Damron, a professor at the Animal Science Department at Oklahoma State University had this to add.

I’m guessing that part of this is better reporting (perhaps just separating out the turkeys from chickens in the counts) and part of it is that turkey is perceived as a “cut above” chicken as a food and is probably being used more in some developing countries (those with population segments that can afford it) as a stepping stone to “better” diets.

If you look at heirloom breeds of turkeys (not the modern big breasted type), you find that the turkey is actually much hardier than it is given credit for and can forage for itself in situations where the chicken can’t.

Carnie news

The latest Scientia pro Publica blog carnival is up at Mauka to Makai. Lots of interesting stuff there, including that fossil that’s been all over the news and some good stuff about reproductive behaviour and how it affects evolution. Keep an open mind, as we know you will. Now, two questions.

  1. Why would a blog carnival that aims squarely at “the public” and not other scientists give itself a fancy Latin name?
  2. And why does any blogger think I enjoy having the text they’ve written obscured by a pointless snapshot of the link I’m considering visiting?

I’m mystified.

Trading farming places

The BBC World Service has a new radio documentary out soon called “Farm Swap.” The conceit is you take a farmer and you plonk him or her into a completely different farming situation. An Ecuadorian organic farmer goes to Hawaii and an English potato farmer goes to Eastern Europe, judging from the brief on-air adverts, but there are no details at all on the website yet. I’m not sure if this is a one-off or a series, but I hope the latter, as it sounds like fun. Especially if subsistence farmers are included, say maize farmers in Kenya and Mexico exchanging experiences, or coconut farmers in India and Ghana. Not enough of that goes on, I think. It would also be nice to see what a particular British allotment gardener would do in another milieu.

Reindeer game up

The species Rangifer tarandus is divided into seven subspecies, but all are in trouble, according to a survey of their status published in a recent paper in Global Change Biology. We’re talking about the animals that are usually called reindeer in Europe and caribou in North America. All across their circum-polar range their populations are undergoing an unprecedented synchronous decline (red denotes herds in decline in the map below, which I hacked from the BBC article quoted below, green indicates those on the increase and dark grey means no data is available).

One subspecies — R. t. tarandus — comprises the semi-domestic and wild reindeer that live across northern Scandinavia and Russia and are so important to the Sami people and others. Here’s one of the authors quoted by the BBC on the causes of the decline:

“If global climate change and industrial development continue at the current pace, caribou and reindeer populations will continue to decline in abundance,” says Vors.

“Currently, climate change is most important for Arctic caribou and reindeer, while anthropogenic landscape change is most important for non-migratory woodland caribou.”

Interestingly, reindeer were recently re-introduced to Britain after a gap of 800 years. I guess their long-term future there must be in question.
