Vaccination Program For Beef Calves (2001 - Clell Bagley), Clell Bagley
All Current Publications
Vaccines are an important tool to use in herd health programs for the protection of animal health. However, vaccines do not prevent all disease by themselves, and should be used in conjunction with good management practices. The timing of vaccination and selection of product are important considerations.
Video Ordering Information For Realizing The Impact Of Injection Site Lesions, Clell Bagley
Video Ordering Information For Realizing The Impact Of Injection Site Lesions, Clell Bagley
All Current Publications
Injection of almost any drug or solution into the muscles of a food animal will result in scar tissue formation and some residual lesion in those muscle tissues. These lesions are very displeasing to consumers if found in meat products. Their presence also contributes to loss of tenderness for much of the remainder of the cut of meat. If found during processing, the lesions can be trimmed out but this still results in trim loss and increased labor costs for the processor.

Realizing The Impact Of Injection Site Lesions, Clell Bagley
All Current Publications
A major effort has been made by the beef industry in recent years to reduce the economic loss from injection site lesions. Injections of almost any vaccine or medication causes some lesion. The extent, severity and economic loss of the resulting lesion can be greatly reduced with cleanliness and by use of careful techniques for the placement of product into specific, designated sites.
Helping Dairy Producers Reduce The Scc, Clell Bagley
Helping Dairy Producers Reduce The Scc, Clell Bagley
All Current Publications
Practicing veterinarians are in an excellent position to help dairy producers recognize and deal with the problem of elevated somatic cell counts (SCC). Yet they are seldom asked to assist. A high SCC is an indication of chronic, subclinical mastitis in the herd and is also an indication of significant economic losses.

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.

Controlling Coliform Mastitis, Clell Bagley
All Current Publications
Coliform mastitis is usually considered as an acute disease although some milder forms and even chronic cases do occur. It is caused by the bacterial organism Escherichia coli, hence the name, coliform. Other, related organisms, Enterobacter aerogenes and Klebsiella pneumoniae, are also often called “coliforms.”

With proper care prior to and during the breeding season, cattlemen can increase the breeding capacity of bulls. Breeding soundness evaluations and trichomoniasis testing are tools which can aid a herd manager as he makes critical decisions for next year’s calf crop.
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 …
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.
Infectious Cattle Diseases And Vaccines, Clell Bagley
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.
Weak Calf Syndrome Or Bvd Fetal Infection, Clell Bagley
Weak Calf Syndrome Or Bvd Fetal Infection, Clell Bagley
All Current Publications
A serious health problem of newborn calves was recognized 20 years ago and termed “weak calf syndrome”(WCS). The Bovine Virus Diarrhea (BVD) virus was often isolated from affected calves and from these herds. In recent years, veterinarians have again been looking at the effects of the BVD virus on the fetus.
Management For Weaning Healthy, Marketable Calves, Clell Bagley
Management For Weaning Healthy, Marketable Calves, Clell Bagley
All Current Publications
Weaning is an extremely stressful time for beef calves and involves the potential for severe economic loss. The most common problems usually involve respiratory and/or digestive diseases. Weaned calves should be retained for 3–6 weeks after weaning.
Weaning Calves Successfully, Clell Bagley
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.
Calf Scours Simplified, Clell Bagley
Calf Scours Simplified, Clell Bagley
All Current Publications
Virtually stacks of material have been written about calf scours and yet it remains as one of the major problems for beef calves. Enough is now known that we should be able to prevent or at least control the great majority of scours outbreak problems.

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.

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.
