Mary had a little lamb, but only once a year. However, Cornell Sheep Program researchers have discovered an unusual form of a gene that prompts ewes to breed out of season as well as conceive at younger ages and more frequently.They conducted a simple genetic test to identify the presence of the unusual form of the gene, the so-called M allele that other researchers had suspected might be correlated with out-of-season fertility, in their test flock and then validated the gene's relationship...

Experts now suggest climate change as the principal culprit behind a mysterious case of sheep shrinking in size over time, AFP reported. Two Scottish islands in the remote Outer Hebrides, Soay and Hirta, have only two sole inhabitants: wild sheep that likely arrived there some 4,000 years ago with the first human settlers. Experts have been studying the impact of weather, food and genetics on a wild animal population using these sheep since the 1950s, due to their isolation and lack of...

U.S. biologists say the 700-mile security wall under construction along the United States-Mexico border could significantly threaten wildlife. The scientists said the wall would alter the movement and connectivity of wildlife and the animals' potential isolation might be a threat to populations of some species. But the researchers said technology and design alterations could dramatically improve the potential for animals to move more freely between the two countries. Oregon State University...

A 700-mile security wall under construction along the United States' border with Mexico could significantly alter the movement and "connectivity" of wildlife, biologists say, and the animals' potential isolation is a threat to populations of some species.However, technology and alterations to the design could dramatically improve the potential for animals to move more freely between the two countries, the scientists added.Results of their study are being published in the journal Conservation...

U.S. scientists say rare sheep called hair sheep could be a key to improving medical diagnostic tests conducted in the developing world. Hair sheep, the scientists said, do not have long, woolly coats that require shearing. But, more importantly, researchers at the Stanford University School of Medicine found not only are the sheep low-maintenance and parasite-resistant, they're also perfect blood donors for microbiology tests necessary to diagnose infectious disease in the developing world....

Milder weather brought about by climate change is causing Soay sheep to shrink on an uninhabited British island, scientists said. On Hirta Island in the St. Kilda archipelago, warmer winters and longer summers mean weaker, smaller Soay lambs are surviving to breed and, in turn, produce smaller offspring, said Tim Coulson, a professor at Imperial College London. In the past, only the big, healthy sheep and large lambs that had piled on weight in their first summer could survive the harsh...

It's not often that one has an opportunity to find humor in the topic of global warming.  However, a peculiar new study pointing to climate change as the explanation behind a shrinking flock of wild sheep on a lonesome island in northern Scotland elicits a grin from even the most trenchant of climate change warriors.For some twenty-five years now, the untamed Soay sheep of Hirta island, part of the remote St. Kilda archipelago, have been an odd source of interest and, more recently,...

Climate change can have devastating effects on endangered species, but new mathematical models may be able to aid conservation of a population of bighorn sheep. The effects of a changing climate on a population of bighorn sheep can be mathematically predicted, as described in a recent paper recommended by Faculty of 1000 Biology members Barry Brook and Lochran Traill. Researchers from Germany, the US, and Mexico studied a population of bighorn sheep introduced to Tiburon island, Mexico, in...

Scientists say they're studying bighorn sheep on an island off the coast of Mexico to determine the effects of climate change on endangered species. The sheep, brought to Tiburon Island in 1975, are not at risk from disease or predators, said Barry Brook, a researcher with Faculty of 1000, a London-based cooperative of international scientists. Climate change is the only variable threat to the sheep, making them good subjects for a mathematical model aimed at predicting the effects of such...

Game theory models predicted that young ravens gain the greatest advantage from hunting in a pack. Now the young birds have figured this out for themselves, and form gangs to oust older raven pairs from tasty carcasses. Young ravens have transformed their hunt for carrion into a joint venture. Instead of searching on their own, some young ravens form bands of as many as 30 birds. "This behavior in young ravens has not been documented before, and came as a surprise to us. But the fun was that...

Hill farming
2013-09-20 13:07:03

Hill farming involves using is a particular piece of land for grazing sheep and cattle. This form of farming is used particularly by the farmers of the UK in the higher elevations. Farmers generally do not have access to winter fodder for their cattle, therefore, sheep farms are typical for such areas. Due to this restricted access, farmers move the herds to lower elevations for feeding. These specific farms are found in the North and South-Western areas of England, as well as the...

Animal husbandry
2013-08-21 10:25:40

Animal husbandry is the caring and breeding of domestic animals by humans, such as cattle, pigs, sheep and horses. Animal husbandry includes grooming, accommodations, and hygiene of the animals. Animal husbandry may also consist of specialized breeding in order to obtain a desirable characteristic, such as strength, temperament, increased production of by-products, or bone structure of the intended animal. Farmers, ranchers, and sheepherders practice animal husbandry as well as those who take...

Mouflon, Ovis aries orientalis
2012-07-31 15:05:48

The mouflon (Ovis aries orientalis) is classified as a subspecies group within the Ovis aries group. The other members of this group are known as urials, or the vignei group. It is thought that the mouflon is the ancestor to all domestic sheep. There are currently five recognized subspecies of the mouflon. This species can be found in the Caucasus, northwestern Iran, and northern areas of Iraq. The only native subspecies of the mouflon is the Cyprus mouflon, with the other four subspecies...

The argali (Ovis ammon), also known as the mountain sheep, is native to Central Asia. Its range includes Tibet, Altay, and Himalaya. Its range extends from Kazakhstan in the west, east to Shanxi Province in China. It also extends from Altai Mountains in the north, south to the Himalayas. It prefers a habitat in the highlands of these regions, at elevations between 980 and 19,000 feet. Its habitat type varies depending upon location. In areas like Kazakhstan, where it is often hunted, it can...
