The Sunday Nation has a feature article in its Lifestyle section on silk making in the semi-arid district of Mwingi in Kenya. Apparently, the silk worm used is a hybrid of the wild species found in the area and the domestic strain. People collect eggs in the bush and rear them in mosquito net cages. When it comes time to harvest the cocoons, some of the pupae are allowed to mature and fly back to the acacia bushes. The Commercial Insect Programme of the International Centre for Insect Physiology and Ecology (ICIPE) has helped a local womens’ group establish the first silk processing factory in the region. According to the article, a different race of the wild silk moth is being evaluated in Pokot and other highland areas for the production of tussar or kosa silk. This is a much prized form of naturally coloured silk produced from cocoons from which the moth has emerged naturally in the wild. Fascinating business.
Where the buffalo roam
There are about 300,000 American bison left. How many of them are genetically pure? I don’t know about you, but I would have guessed many more than the 10,000 quoted in this article. The vast majority have some cattle genes, it turns out, due to past hybridization efforts by ranchers. The largest “un-contaminated” herd is in the Yellowstone National Park. Scientists are doing DNA studies across the range of the species to develop a management strategy. There are plans to reconstitute large tracts of the prairies, and pure bison are needed to roam them. But my question is: how many cattle herds have buffalo genes?
Conserving animal genetic resources in Vietnam
A CIRAD project is using both somatic cloning and in situ approaches to conserve genetic resources of various threatened useful wild animals (including livestock relatives) in the highands of Vietnam. GIS is also being used to map genetic diversity as measured by molecular markers. The results will be extended to prepare a conservation strategy for the region as a whole.
Livestock at risk
Another report from FA0 says that 20 percent of the world’s livestock breeds are at risk. And the culprits are those we’ve come to know and love; intensification, globalization, modernization. So what’s new? They may be planning to do something about it, that’s what. The report is part of a process leading up to the first International Technical Conference on Animal Genetic Resources, to be hosted by the Government of Switzerland, in Interlaken in September 2007. Anyone out there want to keep an eye specifically on that topic?
Last of the shepherds
THE day is darkening, and Antonio el Negro, as he is known to his friends in the mountains, heads down to the El Yoni venta in El Burgo for a drink and something to eat. Antonio, as his nickname would suggest, is dark-skinned with black hair, and he has been looking after sheep and goats on this mountain terrain around El Burgo for as long as he can remember. His flock currently numbers 500, although he is the first in a long line of goatherds to have become a shepherd instead. “I prefer sheep,” he smiles.
Go on, give yourself a treat; read the whole romantic piece about the shepherds of Andalucia in Spain. There’s some science there, if you need any.
