#What Is Veal? Like many culinary terms veal came to English from French. It refers to the meat of a young cow
or calf as opposed to beef (also from French) an adult cow's meat. Prized for its tenderness
and delicate flavor veal has appeared in the cuisines of Italy France and Germany for centuries.
It dates back to (at least) Roman times when Emperor Alexander Severus outlawed calf slaughter due to overconsumption.
                   Â
   The different varieties of veal depend on the calves'diet. Milk-fed calves (actually raised on a milklike supplement) produce a pale pink veal
while grain-fed calves produce redder fattier meat. Veal production has prompted strong criticism from animal welfare groups.
Traditional practices place calves in small (30 by 70 inch) individual crates that prevent much movement;
By depriving the animals of exercise veal producers aim to reduce muscle growth keeping the meat tender.
and the American Veal Association has committed to ending the practice by 2017. Follow Michael Dhar@mid1980. Follow Livescience@livescience. We're also on Facebook & Google+A

#Early Life Pain May Affect The next Generation A mom's painful early life experiences might influence her offspring's sensitivity to pain according to a new study of lambs and ewes.
It's likely that the same is true in lambs though the link is currently speculative.
Next the researchers tested the lambs of the 20 ewes in the study for their sensitivity to discomfort.
To do so they pressed a metal rod into the lambs'feet gently just until the lamb twitched
The lambs from ewes that had had an early-life infection responded more promptly than the lambs born to ewes in the other groups.
Epigenetics could be the cause of the lambs'greater sensitivity Mendl said but researchers don't know that yet those lambs might also have altered sensitivity because of their more difficult birth experiences for example.
A lot more work needs to be done to fully understand the results Mendl said starting with reproducing the findings and investigating their causes.

#Shorebirds Adopt Baby Duckling, Cuteness Ensues A family of long-legged shorebirds adopted a fuzzy baby duckling this month in California's San francisco bay.
U s. Geological Survey (USGS) biologist Jarred Barr discovered the duckling among a brood of downy avocet chicks on July 2.
We don't know how the duckling got separated from its family but they were all feeding already
But this is the first time the USGS biologists have discovered a duck-avocet adoption. Hartman thinks it's likely the duckling was separated from its family after it hatched
and glommed on to the avocets. This is cross-species and it's really cross-order.

and after spotting a mallard family a few ponds over from the avocet-duck flock he went back for the duckling
Both ducklings and avocets are resourceful babies however with the capability to feed on their own soon after hatching.
As long as the duckling finds the right food sources and the right habitat it could survive on its own the scientists said.
They are normally 26 to 34 inches (66 to 86 centimeters) from head to rump.

#Rabbits: Habits, Diet & Other Facts Rabbits are small mammals with fluffy short tails whiskers and distinctive long ears.
There are about 30 species of rabbits around the world and while they live in many different environments they have many things in common.
While many people think rabbits are about the size of a cat some rabbit species such as the jackrabbit can grow to be as big as a small child.
Small rabbit species can be as little as 8 inches (20 centimeters) in length and weigh less than a pound.
Larger rabbits grow to 20 inches (50 cm) and more than 4 pounds (1. 8 kilograms.
The world's largest rabbit clocked in at 4 feet 3 inches (129.54 cm) and 49 pounds (22 kg.
The largest rabbit breeds are checkered giant Flemish giant French lop and giant chinchilla. These mammals are known for their insatiable reproductive habits for good reason.
They breed three to four times each year. This is because only 15 percent of baby rabbits make it to their first birthday.
So to ensure that the population grows rabbits have more babies. Each pregnancy produces three to eight babies called kittens or kits.
Bunny is just an affectionate name for a rabbit young or adult according to Small Pet Select.
After four to five weeks a kit can care for itself. In two or three months it is ready to start a family of its own.
If there is a lack of natural predators an area can quickly become overrun with rabbits. Rabbits are omnivores.
This means that they have based a plant diet and do not eat meat. During warm months rabbits will nibble on herbs peas grasses clover lettuce and greens.
In the winter months they eat twigs bark and buds. While originally from Europe and Africa rabbits now call many places home.
Domestic rabbits need a regulated environment to protect against heat exhaustion or hypothermia. Wild rabbits don't have this problem
and make their homes in various temperature extremes. Wild rabbits can be found in woods forests meadows grasslands deserts tundra and wetlands.
Wild rabbits create their own homes by tunneling into the ground. These tunnel systems are called warrens
and include rooms for nesting and sleeping. They also have multiple entrances for quick escape.
Warrens can be as deep as 9. 84 feet (3 meters) underground according to the Young People's Trust for the Environment.
Domestic rabbits often live in cages though many rabbit owners let their pets run freely throughout their home for exercise and only place the rabbit in a cage for sleeping.
Rabbits are very social creatures and live in large groups called colonies. The busiest time of day for rabbits is at dusk and dawn.
This is when they venture out to find food. The low light allows them to hide from predators.
While many rabbit species are populated over the Oryctolagus cuniculus or European rabbit is considered within near threatened range by the IUCN.
Rabbits can be very crafty and quick. To get away from a predator a cottontail rabbit will run in a zigzag pattern
Rabbits don't get a lot of nourishment from their diet. They often eat their own excrement to access any remaining nourishment that their digestive system may have missed the first time.
Rabbits and hares are two different species. The biggest difference between the two is what their babies look like at birth.
Newborn hares are born with fur and are able to move as well as see shortly after birth.
Rabbits have a near 360-degree vision and can even see behind them. They have just one blind spot right in front of their nose.
Rabbits are popular in mythology and culture. Many people believe carrying a rabbit s foot will bring good luck.

They are 32 to 37 inches (81 to 94 centimeters) from head to rump. Their tail adds another 16 inches (41 cm) to their length.
They are thought typically to be only meat eaters but they are actually omnivores they eat meat and vegetation.
They eat small game such as rodents rabbits fish and frogs and larger game like deer.

On May 7 1964 a catering-size can of corned beef from Rosario Argentina was opened in a supermarket in central Aberdeen.
The sun shone on the meat. Corned beef is cooked in the can and should be sterile.
But it wasn t. It had been contaminated after cooking when the can was cooled with untreated water from the River Parana.
The bacteria in the corned beef in the window grew vigorously. The first person to fall ill developed symptoms on May 12.
The probable explanation is that a slimming regime incorporating cold meats and salad was popular at the time.
#and beef cattle raisers in Paraguay Kenya and Tanzania suffered economically as importing meat came to be seen as high risk in the initial panic about the source.
All the infections were caused by eating contaminated corned beef or cold meats cut with the same slicer.
New cases continued to appear not because the source of infection was still active but because the incubation period the time between being infected
(even if as we saw in the horse meat scandal the label does not always accurately describe the contents).
The realities of 21st century mass production of cheap meat are likely to have driven up infection for example.
Supersize me While beef consumption worldwide has been going up Americans have cut back considerably since the mid-1970s largely due to rising beef prices and a greater awareness of the health risks associated with consuming red meat.
As of 2012 the average American was eating 52 pounds a year about 30 pounds less than four decades ago.
Regardless we still consume more per capita than the citizens of every other country excluding the beef emporiums of Argentina Brazil and Paraguay.
Eating less beef is a good thing. After all it's been linked to a host of potentially life-threatening problems including coronary heart disease and breast colon and prostate cancer.
But instead of forsaking beef altogether financially strapped Americans are eating more ground beef instead of steak and other pricier cuts.
These new upscale burger restaurants are serving more meat between the buns with at least twice the calories Hurley said.

when deciding on a restaurant 58 percent said they would prefer that restaurants serve meat
and grass-fed beef and 41 percent are looking for natural and organic fare. To further differentiate themselves from traditional fast-food burger chains some premium burger chains have jumped on the sustainability bandwagon.
Shake Shack's menu boasts that its burgers are 100-percent all-natural Angus beef vegetarian-fed humanely raised and source-verified.
Elevation Burger goes even further promising 100-percent USDA-certified organic grass-fed free-range beef.
Hormones and antibiotics aside the biggest distinction when quantifying beef's marginal benefits to human health
If you're going to eat beef you want the grass-fed variety. A 2010 study in Nutrition Journal reviewed three decades of research comparing the nutritional profiles of grass-fed
It turns out that grass-fed beef has lower levels of unhealthy fats and higher levels of omega-3 fatty acids
and E as well as cancer-fighting antioxidants Not many better-burger chains offer grass-fed beef however because there's not a lot of it around making it more expensive
and because it has a grassy flavor that Americans accustomed to fatty grain-fed beef find unfamiliar.
and a cursory Internet search turned up only three other premium burger chains featuring grass-fed beef:
Beef is the worst meat for the climate Before you begin searching high and low for a grass-fed burger
Agriculture accounts for about 6 percent of total U s. global-warming emissions and beef production alone accounts for 2. 2 percent of the total according to a 2011 Union of Concerned
Scientists (UCS) report Raising the Steaks. That's roughly equivalent to the annual heat-trapping emissions from 33 average-sized coal-fired power plants.
So while the emissions from beef production may seem relatively small it is not an insignificant part of the problem.
The more beef Americans eat the worse global warming gets said Doug Boucher director of UCS's Tropical forest and Climate Initiative.
and the climate if they replaced beef with poultry or pork or ate less meat altogether.
Beef is what scientists call an inefficient protein Boucher said. It requires substantial resources to produce compared with
Solutions for Deforestation-Free Meat found that beef production uses about 60 percent of the world's agricultural land
's analysis. It found that beef requires 28 times more land and 11 times more water to produce than the equivalent calories from pork
or poultry and produces at least five times more carbon pollution. The contrast between beef and such staples as wheat rice and potatoes is even more stark.
Beef requires 160 times more land and results in 11 times more heat-trapping emissions.
The U s. beef industry is convinced not. The PNAS study represents a gross over-simplification of the complex systems that make up the beef value chain a point
which the authors acknowledge Kim Stackhouse-Lawson director of sustainability research for the National Cattlemen's Beef Association said in a statement.
The fact is the U s. beef industry produces beef with lower greenhouse gas emissions than any other country.
Stackhouse-Lawson is not entirely off base. Methane and nitrous oxide emissions from livestock in the United states and other developed countries peaked in 1970
and have fallen 23 percent since according to a July study in the journal Climatic Change. That decline however has been offset by rising livestock emissions in developing countries
which more than doubled largely due to increased domestic demand for meat. The study found that worldwide livestock emissions jumped 51 percent from 1961 to 2010.
Even though we're eating less beef these days which explains the drop in U s. livestock emissions we're still No. 1 in the total amount of tonnage.
Last year we put away 11.6 million metric tons of beef and veal according to the U s. Department of agriculture.
Americans'love affair with beef has consequences beyond our borders. According to Boucher's 2012 study U s. beef consumption helps drive tropical deforestation which is now responsible for about 10 percent of the world's carbon emissions.
As demand for beef goes up worldwide so does deforestation. If U s. consumers ate less beef Boucher explained U s. producers would have more to export to other countries.
And those exports would displace exports from Latin american beef producers reducing incentives to cut down tropical rainforests for cattle pasture land.
The bottom line is U s. demand for beef plays a substantial role in global markets Boucher said.
If U s. consumers want to eat'better'burgers they should consider turkey burgers veggie burgers and other alternatives.
All of those are much better for the environment whether you're talking about climate emissions land use water use or nitrogen pollution.
but a lot of improvement could come from eating pork or chicken instead of beef. Negin's most recent op-ed was Montana:
