Lead is the most common cause of cattle poisoning in Alberta. Hundreds of animals in the province die each year or perform poorly after accidentally ingesting lead. Gradual poisoning may also occur in areas with heavy industrial pollution.
Lead poisoning can affect any cattle operation. Lead was likely responsible for the death of thousands of cattle and illness among tens of thousands of cattle over the past 20 years.
Some trends have emerged from the incidents of lead poisoning in Alberta. Poisonings usually involve animals from well-managed farms and ranches. Sometimes only one calf is affected. At other times more than 20 cows have been lost in a single poisoning incident.
Colorado State Student Named Intern at Leading A.I. Organization

He will be based at the company’s headquarters in Plain City, Ohio.
Borror is a junior at Colorado State University, Fort Collins, Colo., where he is majoring in both animal science and agricultural business. He is an active member of the intercollegiate meats judging team and the seed stock marketing team.
Foot Rot Drivers Define Prevention
Up front, researchers estimate about 20% of all diagnosed lameness in cattle is due to Foot Root. And, lameness costs the cattle industry heavily each year. As an example, in one study of five western feedlots, 13.1% of the 1.8 million head of cattle on feed were treated for health problems—lameness accounted for 16% of those and 5% of the death loss. The lame cattle accounted for all non-performing cattle that were sold, returning only 53% of the original purchase price.
Closer to home, research continues to underscore the increased cost of gain and reduced gains stockers experience at the hands of Foot Rot.
Typically Foot Rot infection is caused by Fusobacterium necrophorum bacteria, which invade and infect the feet of cattle. Initial causes, created pathways for the bacteria to gain access, include injury or the softening and thinning of the skin between the toes by puncture wounds or prolonged exposure to wet conditions.
Board orders testing of imported bulls
Farm and Ranch Guide
The North Dakota State Board of Animal Health has ordered testing requirements for most bulls imported into the state to prevent the spread of trichomoniasis.
A venereal disease of cattle, trichomoniasis causes fetal abortions, uterine infections and increased numbers of open cows. It is a reportable disease in North Dakota.
The requirements were implemented July 23, according to the state veterinarian, Dr. Susan Keller, as a result of trichomoniasis infections reported in surrounding states.
Livestock Angles: Optimism in the cattle market
The cattle market has been uneven during the past few weeks and is generating mixed signals. Cash prices are near steady, although they have fallen and rebounded during the past few weeks, while the futures market has rallied particularly in the deferred contracts.
Cutouts prices appear to have stabilized and have even inched slightly higher in recent days, but packers are still not in a profitable margin situation at this point. Boxed beef movement has been slow, reflecting retail reluctance to accumulate beef while competitive meats are much cheaper and easier to feature, providing a better profit margin.
Cattle Feedlot Odors Can Be Controlled
The recent hot, humid weather is bringing out odors at some North Dakota cattle feedlots.
“Feedlots do not need to smell,” says Karl Hoppe, area Extension Service livestock specialist at North Dakota State University’s Carrington Research Extension Center. “Feedlots may have a slight odor, but they do not have to have an overwhelming odor.”
Proper feedlot design and management are the keys to keeping smells to a minimum, he adds.
One of those management tools is pen stocking density.
Now is the time to plan for preconditioned calves

The time is fast approaching in the annual cow-calf cycle when thoughts shift from production to marketing. Now is the time to start thinking about preparing calves for market.
One might say this is old hat by now, but it really isn’t. The need to provide protection for calves, whether one weans them at home or sells them right off the cow, is a vital part of successful management.
At the Dickinson Research Extension Center, the calves receive vaccinations for infectious bovine rhinotracheitis (IBR), bovine viral diarrhea type I and II (BVD), bovine respiratory syncitial virus (BRSV) and bovine parainfluenza 3 (PI3). These viral agents typically are present and can negatively affect calves.
