Clinical Trials With Copper Supplementation, Clell Bagley, Norris Stenquist, Dennis Worwood Jul 1997

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.

Toxic Contaminants In Harvested Forage, Clell Bagley

All Current Publications

Harvested forages are vitally important and commonly used for beef production. But contamination can occur which results in reduced forage quality and palatability or may even result in animal illness and death. Outlined below are some of the common problems that should be considered.

Mycotoxins, Clell Bagley

All Current Publications

Certain metabolites of some fungi (molds) are poisonous (toxic). Fungal poisons have been known for many years, but they were not considered a major factor in animal disease until fairly recently. Because the prefix myco- refers to fungi, these toxins are termed mycotoxins. Penicillin is derived from a fungus and could be termed a mycotoxin, in relation to bacteria which are sensitive to it.


Vaccinating To Prevent Pneumonia, Clell Bagley, Donald Snyder, Nyle Matthews Jul 1997

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.

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.

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.


Controlling Coliform Mastitis, Clell Bagley Jul 1997

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.”

Cat Plague - Veterinarian Caution, Clell Bagley

All Current Publications

Plague has been in the news from several areas in the much from world. The Center for Disease Control has become especially concerned about two aspects of plague (and these concerns affect veterinarians in Utah very directly); first, plague has been increasing in recent years in the western states and second, cats are being recognized more often as being associated with human plague cases.

Improving Reproductive Performance Of The Ewe, Clell Bagley

All Current Publications

The western range ewe is a tremendously productive animal as evidenced by the excellent reproductive rates that are achieved by some producers, some years. Yet many other factors such as weather, disease and forage availability can drastically reduce their productivity. It is a major management challenge to control or even minimize the effect of these interacting factors. Some of those of greatest priority are listed and briefly discussed.

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.


Beef Quality Assurance Notes, Clell Bagley Jul 1997

Beef Quality Assurance Notes, Clell Bagley

All Current Publications

Most of us have felt that injections given to a calf early in its life would be of little problem by the time it went to slaughter. We were WRONG!!! Colorado State University has provided the data and the pictures to prove it. In fact, 90% of the lesions found at slaughter originated during the cow-calf, stocker or early feeding periods. And, injections given while the calf is young caused greater lesions than those given when it was older. The study followed calves injected at branding or weaning and found a high incidence of lesions and blemishes when they went …

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 Jul 1997

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 …


Copper Deficiency In Utah, Clell Bagley, Norris Stenquist, Dennis Worwood Jul 1997

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.


Disease Resistance In Cattle, Clell Bagley Jul 1997

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.
