Immunologic and physiologic differences of stressed and unstressed beef calves
American Society of Animal Science
A research team from the University of Georgia, Athens recently compared cell-mediated immune responses following ex vivo stimulation with viral and bacterial respiratory pathogens in stressed and unstressed beef calves.
Tips offered to break the fluke life cycle in cattle.
Angus Beef Bulletin
If you’re grazing cattle in coastal areas or river bottom pastures, then your cattle may be at risk for picking up liver flukes. It’s important to consider control measures because conditions in these areas support the fluke life cycle.
JBS SA Monitors Suppliers With Satellites
JBS SA monitors the origin of cattle it buys in Brazil using satellites, according to a Reuters report. Citing heightened concerns about environmental preservation and sustainable beef production, JBS Chief Executive Gilberto Tomazoni said the company is using satellite technology to monitor a 450,000 square-km (280,000 square mile) area of Brazil to guarantee it is not buying cattle from deforested areas.
Fall calving – worth the off-season plunge?
Heather Smith Thomas
There are advantages and disadvantages to every calving season; producers need to figure out what works best for their own climate and management system. Dr. George Barrington, Washington State University, says the advantages and disadvantages to fall calving are partly geographic, with regional and management differences. “Some producers in the Intermountain West have successful fall-calving programs, even though it might work best in a milder climate,” he says.
Why Consider Backgrounding a Calf?
Ohio Beef Cattle Letter
Typically, when feed prices go down, we see feeder calf prices begin to climb as a corresponding move. That is, unless fed cattle prices are unstable or declining. A fire in a Kansas cattle packing plant just before a report detailing that the U.S. might have planted more acres of corn than earlier anticipated caused the perfect storm that allowed pressure on feeder calf prices at the same time as declining feed prices.
Coyotes Can Protect Your Livestock From Predators
Livestock losses are an unfortunate reality of ranching and the use of traps and snares is a common way to attempt to reduce predator-livestock conflict. However, one USDA study (Shivik et al. 2003) noted that for many types of predators, there is a paradoxical relationship between the number of predators removed and the number of livestock killed. Surprisingly, these researchers found that as more predators were removed, more livestock were killed.
Bunk Management and Feed Delivery
When it comes to nutritional management of growing and finishing cattle, the scientific aspects tend to get the most attention.
