...first surfaced, health officials have focused mostly on Asia as the breeding ground for the world's next pandemic flu virus. But Daszak points out that Mexico, where people, pigs and poultry can exist in close proximity, is an overlooked hot spot for new viruses. Given the booming global livestock trade - more than 1.5 billion live animals have been shipped to the U.S. from all over the world in the past decade - it's possible that the A/H1N1 virus originated in an Asian bird that was exported to Mexico, where it may have reassorted in a pig before infecting people...
...burping, belching and excreting copious amounts of methane - a greenhouse gas that traps 20 times more heat than carbon dioxide - India's livestock of roughly 485 million (including sheep and goats) contributes more to global warming than the vehicles the animals obstruct. With new research suggesting that methane emission by Indian livestock is higher than previously estimated, scientists are furiously working at designing diets to help bovines and other ruminants eat better, stay more energetic and secrete smaller amounts of the offensive gas. (See pictures of India's largest ruminant: the Asian elephant...
Last month, scientists at the Space Applications Centre in Ahmedabad in western India published a pan-India livestock methane-emission inventory, the first ever, which put the figure at 11.75 million metric tons per year - higher than the 9 million metric tons estimated in 1994. This amount is likely to increase as higher incomes and consumption rates put pressure on the country's dairy industry to become even more productive. (See pictures of China's cow town...
Already the world's largest producer of milk, India will have to yank up production from the current 100 million metric tons to 180 million metric tons by 2021-22 to keep pace with growing population and expanding disposable incomes. Livestock such as cows, buffalo, goats, sheep, horses and mules are indispensable to India's rural economy - whether the animals are yoked to plow land, raised for milk and manure or harnessed to pull carts to move goods and people. The Ministry of Agriculture estimates that livestock contribute 5.3% to total GDP, up from 4.8% during 1980-81. But, says...
...starters, most Indian livestock is underfed and undernourished, unlike its robust counterparts in richer countries. The typical Indian farmer is unable to buy expensive dietary supplements even for livestock of productive age, and dry milch cattle and older farm animals are invariably turned out to fend for themselves. Poor-quality feed equals poor animal health as well as higher methane production. Also, even when Western firms are willing to share technology or when Western products are available, these options are often unaffordable for the majority in India. For instance, Monensin, an antibiotic whose slow-release formula reduces methane emission...
