Most Passive Immunity Occurs in the First 6 Hours
Despite our best efforts, a few calves will be born via a long, hard delivery. They may be sluggish or weak at birth and slow to find the cow and nurse. These calves are more prone to scours or pneumonia as babies and “poor-doers” later in life.
Resistance to disease is greatly dependent on antibodies or immunoglobulins and can be either active or passive in origin. In active immunity, the body produces antibodies in response to infection or vaccination. Passive immunity gives temporary protection by transfer of certain immune substances from resistant individuals. An example of passive immunity is passing of antibodies from dam to calf via the colostrum (first milk after calving). This transfer only occurs during the first few hours following birth. Research from the USDA station in Nebraska has indicated that successful transfer of passive immunity (during the first day of life) enhances disease resistance and performance even through the feedlot phase.
Carcass Ultrasound 101: Measures of muscle
By Patrick Wall, Director of Communications, The National CUP Lab
Farm & Ranch Guide
Undoubtedly, one of the more enjoyable eating experiences from the beef carcass is the ribeye steak.
Often referred to as the longissimus dorsi in research journals, this muscle gets the vast majority of the attention in genetic selection as well as at the restaurant. Ribeye Area (REA) is the sole measure of muscle in a purebred animal’s Expected Progeny Difference (EPD) profile, unless you include collaborative measures like % Retail Product, Yield Grade, or some Indexes (which use REA in the formula).
The absence of other muscle selectors is not for lack of trying. Researchers have simply been unsuccessful in finding an indicator of muscle that is either more accurate or more practical than REA. This creates a challenge for beef cattle breeders to use somewhat limited resources to make progress in red meat yield, not just REA.
Reducing winter cold stress on cattle with proper nutrition
By STEVE BOYLES, Ohio State University Beef Extension specialist and
JEFF McCUTCHEON, Knox County ANR agent
Factors that create stress during the winter months are cold, wind, snow, rain and mud. The primary effect on animals is due to temperature. All these factors alter the maintenance energy requirement of livestock.
Maintenance requirement can be defined, as the nutrients required for keeping an animal in a state of balance so that body substance is neither gained nor lost. An interesting thing to note is that while energy requirements increase, protein requirements remain the same.
Some published sources contain nutrient requirements for beef cattle that include guidelines for adjusting rations during winter weather.
Even without published sources, competent livestock producers realize the need for more feed during cold weather. Make sure that water is available. If water is not supplied, cattle will reduce feed intake.
Ruling plows under five Jersey farmers
New Jersey Voices
One of the promises of America is, if you work hard and invest in yourself, are self-sufficient and stubbornly persistent, good things will come of your efforts.
It is called The American Dream.
The five old farmers in Mercer County Court yesterday believed in all of that, even when the dream was elusive. Even when prices tumbled, or bitter frosts came late, or there was not enough rain, or too much.
They stuck it out, decade after decade, some because their grandfather and fathers had done it, some because they wanted to preserve it for their sons.
Calendar Set for 2008 Tennessee Field Days
For many regional farmers, the weather made 2007 a difficult year. While continuing education can’t affect killing freezes or drought, it can help your bottom line. That’s why field days are so valuable say officials with the University of Tennessee Institute of Agriculture.
The Institute sponsors several educational events throughout the year at 10 research and education centers within the Tennessee Agricultural Experiment Station system. Each event is designed to help farmers improve their operations.
Feed Montana programs put beef on every plate
By DENNIS MCDONALD, Melville, Mont., rancher
The Prairie Star
Montana has 47,000 families who often go to bed hungry. There are 314,000 Montanans, from infants to the elderly, who often are malnourished.
Ten percent of Montanans over 60 are hungry and approximately 45 percent of the hungry live in rural Montana. This state of affairs is unacceptable and unless more is done the problem may worsen.
Presently, the economy seems to be heading toward recession, foreclosures are at an all-time high, unemployment is rising, fuel costs are at historical highs, the inflation index for the month of December is at a one month all-time high, and the trade deficit for 2007 will be $800 billion. Since 1998, 3.3 million jobs nationwide have been outsourced.
Bluetongue funding offered, vaccine developed
Markos Kyprianou, European commissioner for health, announced today that the European Commission will make funds available to co-finance an emergency mass vaccination campaign against bluetongue in the European Union in 2008. Bluetongue is an insect-transmitted viral disease that affected thousands of animals across 11 member states in 2007. Vaccination is regarded as one of the most effective ways of controlling and even eradicating bluetongue.
Cattle feed convenience can have its drawbacks
People running beef cattle increasingly value convenience over nutritional content when making feed purchases, according to Eldon Cole, University of Missouri Extension livestock specialist.
“This trend is due to time, availability, advancing age and the physical ability of cattle owners. As newcomers invest in the cattle business, they choose more convenient, less traditional methods of feeding,” said Cole.
Self-feeding supplements are a popular convenience that do have drawbacks.
Animal rights gets Obama’s vote
The Denver Post
Barack Obama says he won’t just be a president for the American people but the animals too.
“What about animal rights?” a woman shouted during a town hall meeting outside Las Vegas on Wednesday.
Obama responded that he cares about animal rights very much, “not only because I have a 9-year-old and 6-year-old who want a dog.”
He said he sponsored a bill to prevent horse slaughter in the Illinois state Senate and has been repeatedly endorsed by the Humane Society.
Cattlemen scramble for scarce hay
Nevada ranchers complain it’s all going to Idaho
Patricia R. McCoy
Ask anyone trying to feed livestock right now: hay is hard to find, and expensive.
Even feeder hay costs $130 a ton or more. Dairy-quality hay sells for $160 a ton or more.
“Prices run the gamut,” said Josh Tewalt, executive vice president of the Idaho Cattle Association. “Some of our guys locked in a supply a long time ago. Others are buying thousands of tons at a time. Beef prices are holding up just fine, but they don’t always keep pace with input costs. Break evens are so high nobody’s getting fat.”
Hay shortages aren’t unusual at this time of year, Tewalt said. Glen Meyer, president of the Idaho Hay and Forage Association, agrees. That’s especially true this year, because drought and heat cut production in Idaho last summer. There’s also a huge cow population in the state.
Lord willing and if the farm bill passes…
Remember when the new year rolled around and we all used to look forward to what the upcoming months would bring?
Old Man Last Year is replaced by Baby New Year. New Year’s resolutions are the topic of everyone’s coffee klatch. Long-range plans forged at holiday family parties and get-togethers are rife with enthusiastic travel and visiting plans.
Farmers are busy planning when and what to plant where. New lambs, calves and chicks are on their way. Car dealers look forward to the new auto models. Teachers and students alike are pleased to see that they are on the downhill slide to summer vacations. Retailers are ordering and stocking shelves of summer suits, swimwear and work clothes.
Cloned meat OK breeds distrust in consumers
Many shoppers say they would steer clear of cloned products, despite FDA assurances
By Liv Osby
The Greenville News
The federal government has cleared cloned meat and dairy products for human consumption, but it could be a tough sell if consumer reaction in the Upstate is any indication.
“My main concern would be the concern of my customers — and they don’t want cloned meat,” said Sam Bowden, owner of The New York Butcher Shoppe on Woodruff Road. “There’s a great deal of skepticism about how much science can really guarantee us there are no consequences.”
But John Gibbons, assistant professor of animal and veterinary sciences at Clemson University, who has been involved in animal cloning at other institutions, said the U.S. Food and Drug Administration’s findings are sound. Moreover, he said, he’d be first in line to buy cloned meat or the meat of clone offspring — depending on the price, which is likely to be hefty.
In the past 30 years, bovines get beefier
By Karen Auge
The Denver Post
Anyone struggling to stuff postholiday thighs into preholiday pants can take comfort in one thing: Humans aren’t the only species weighing more these days.
Cattle are getting bigger too.
Between 1970 and 2006, the average weight of the cattle walking around our nation’s plains and our city’s National Western Stock Show has ballooned 23 percent, from 1,035 pounds to 1,275 pounds, according to the U.S. Department of Agriculture.
During the same time, the average dressed weight — the carcass product — from each animal has gone up 25 percent, from 624 pounds to 781 pounds.
Clone ruling views mixed
BY JAMES HAGGERTY
The Times Tribune
Area farmers stake positions on both sides of the fence following the government’s approval of cloned animal products in the food chain.
“That technology is still a little out there for me. I don’t know whether everything is fine with cloned animals,” said Paul Manning, owner of Manning Farm Dairy near Dalton, which sells milk and ice cream products at the farm and at stores in Clarks Summit, Dunmore and Scranton.
“The food safety question should always be in the hands of the medical and scientific communities,” said Keith Eckel, a Schultzville farmer who grows tomatoes, corn and other vegetables in Lackawanna, Luzerne and Wyoming counties. “I think they are absolutely right. I can’t judge the science, but that’s why we have the FDA.”
S. Korea mulling phased reopening of U.S. beef imports: sources
South Korea is considering an option of fully reopening U.S. beef imports through a step-by-step process, possibly including shipments of previously unaccepted parts including bones, informed sources said Friday.
The discovery of mad cow disease at a U.S. cattle farm in 2003 prompted South Korea to stop all imports of American beef. Seoul partially lifted the restrictions in January 2006, allowing imports of boneless products, but suspended imports last year after repeated discoveries of bone fragments in U.S. shipments.
