Vaccinating To Prevent Pneumonia, Clell Bagley, Donald Snyder, Nyle Matthews
All Current Publications
Bovine Respiratory Disease (BRD) is a major problem for cattle and it continues to cause serious economic losses. Pneumonia is its most serious form. BRD causes increased death losses, higher medication and labor costs, and lost production. It occurs most commonly within a few weeks of weaning and is especially troublesome then. BRD is more serious in calves which are shipped long distances right after weaning and is often referred to as shipping fever.

If you see clippings from ornamental, evergreen shrubs that someone has dumped where cattle, horses, sheep, etc., can eat them, you had better move the plants or the animals. If you don’t, expect some dead animals.
Ammonia Toxicity In A Herd Of Beef Cattle, Clell Bagley
Ammonia Toxicity In A Herd Of Beef Cattle, Clell Bagley
All Current Publications
A Utah producer lost 22 out of 50 head of cows in May, due to ammonia toxicity. He used a liquid fertilizer tank to haul water to the cattle. He had done this for two years previously, and with washing out thoroughly, there had been no problem. But this time some fertilizer was evidently left in, mixed with the water and resulted in the toxicosis.

Infectious Cattle Diseases And Vaccines, Clell Bagley
All Current Publications
Vaccines are available for 20 to 30 infectious diseases of cattle. With the various brand names and different combinations available, the choice of vaccines can become very complicated. Calves vaccinated under 6 months of age should generally be re-vaccinated again after that age to provide a longer lasting immunity.
Assisting With Calving, Clell Bagley
Assisting With Calving, Clell Bagley
All Current Publications
Calving season is a busy time of year for cattlemen and it is a critical step toward a productive year. The first rule is frequent observation of those cows due to calve, especially the first calf heifers. This is usually a very busy time of year and some extra help during this season will more than pay for the cost through extra calves saved. Even wives and older children can help a solo producer get some needed sleep. If, they have been taught how to observe, they can tell when a calving cow needs help and if there’s a need …

Understanding Bull Breeding Soundness Exams, Clell Bagley, Craig Burrell
All Current Publications
Controversy still exists about Breeding Soundness Examinations (BSE) and what they can and cannot do. At times they are not used because of a lack of understanding of their value while at other times they are used with unrealistic expectations. First, BSE is performed to identify bulls with reduced fertility not just to find those which are sterile. Very few bulls are sterile but a significant percent have reduced fertility.
Preventing Calf Losses, Clell Bagley
Preventing Calf Losses, Clell Bagley
All Current Publications
Many beef producers and practicing veterinarians noted there were higher than normal calf death losses during the 1993 calving season. We were especially aware of the increased losses here in the western states, but there were also heavy losses in the midwest and east, so the problem was very widespread.
Clinical Trials With Copper Supplementation, Clell Bagley, Norris Stenquist, Dennis Worwood
Clinical Trials With Copper Supplementation, Clell Bagley, Norris Stenquist, Dennis Worwood
All Current Publications
Copper deficiency has been diagnosed in beef cattle herds in many areas of the intermountain west. Copper supplements are not widely used, even though several products are available. It is difficult to correct a deficiency because too much copper can result in copper toxicity or poisoning. Toxicity is less a hazard with cattle than with sheep, but it is still a problem to guard against. Periodic monitoring of the herd’s copper status is essential for proper supplementation.

Weaning Calves Successfully, Clell Bagley
All Current Publications
The production loss and death loss of calves at weaning is second only to the losses at calving. Weaning is a very stressful time and bovine respiratory disease (pneumonia, shipping fever, etc.) is a common problem. Coccidiosis and other digestive problems, such as acidosis, (grain overload) are also common.

Copper Deficiency In Utah, Clell Bagley, Norris Stenquist, Dennis Worwood
Copper Deficiency In Utah, Clell Bagley, Norris Stenquist, Dennis Worwood
All Current Publications
Copper deficiency has been diagnosed in a number of Utah cattle herds, yet few producers use copper supplements. Cattle deficient in the element can suffer significant production losses. Producers need to balance both the effects and the costs of copper supplements. Too much copper can cause copper toxicity or poisoning. And adding copper may not be economical if animals are only marginally deficient. Further, the deficiency may occur only on specific feeds or pastures, correcting itself when cattle are moved.
Dealing With Drought And Short Feed Supplies For Beef Cattle, Clell Bagley
Dealing With Drought And Short Feed Supplies For Beef Cattle, Clell Bagley
All Current Publications
Weather patterns greatly impact feed supplies for almost all areas of Utah. Both grazing and harvested feed supplies are usually reduced with drought conditions. The hay QUALITY may actually be improved because of the excellent drying conditions for harvest. Taking good care of hay supplies to protect that quality may allow use of less feed in the winter to achieve acceptable results.

Health Programs Which Improve The Marketability Of Calves, Clell Bagley
All Current Publications
The “winds of change” have the potential to drastically change the marketing of beef calves in the next few years. Economic pressures may force greater conformity in the way cow-calf producers manage and prepare their calves for market. Those who are slow to conform may be at a disadvantage for marketing.
Disease Resistance In Cattle, Clell Bagley
Disease Resistance In Cattle, Clell Bagley
All Current Publications
The ability of cattle to resist the many disease processes to which they are exposed is truly amazing. And yet, when several adverse factors combine, this resistance can be overcome and result in a herd disaster which is just as amazing. This discussion will be broken down into four major areas. But it is the combined functioning of all four areas that actually provides disease resistance.
