Bluetongue In Cattle, Clell Bagley Jul 1997

Bluetongue In Cattle, Clell Bagley

All Current Publications

Bluetongue (BT) is a viral disease that is spread mainly by one specific type of gnat. Other gnats and blood sucking insects may occasionally transmit BT, but they are much less important in its transfer. Cattle are the main reservoir for overwintering of the virus in temperate climates.

Preventing Calf Losses, Clell Bagley Jul 1997

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.

Mycotoxins, Clell Bagley Jul 1997

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 Jul 1997

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.

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.

Understanding Bull Breeding Soundness Exams, Clell Bagley, Craig Burrell Jul 1997

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.

Updating Your Herd Health Plan, Clell Bagley

All Current Publications

Animal health is not sold in a bottle, syringe or sack. It comes as a result of proper management. The increased concentration and movement of cattle and demands for greater production necessitate an improved level of management to maintain cattle health.

Breeding Soundness Examination Of Rams, Clell Bagley Jul 1997

Breeding Soundness Examination Of Rams, Clell Bagley

All Current Publications

The objective of a breeding soundness examination (BSE) of rams is to evaluate and classify their potential breeding ability. This process should include evaluation of their physical condition as well as an evaluation of the semen itself. A BSE does not include an evaluation of sex drive or breeding behavior because there are no standardized criteria by which to judge these. Their best evaluation at present will come from observation of the rams breeding behavior after introduction into the ewe flock.

Improving Reproductive Performance Of The Ewe, Clell Bagley Jul 1997

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.

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 …

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.

Halogeton Toxicity In Cattle, Clell Bagley

All Current Publications

“Everyone” knows that halogeton is toxic to sheep, but sometimes we forget that it is also toxic for cattle. If cattle eat enough of it, it will kill them. One autumn incident resulted in the death of over 40 head of cows in a multiple owner grazing herd.

Controlling Internal Parasites In Utah Cattle, Clell Bagley

All Current Publications

Most cattle harbor some internal parasites (worms) and Utah cattle are no exception. The varied geographic and climatic conditions of Utah allow for tremendous variation in the parasite burden of different cattle herds. The numbers of parasites varies from very few to so numerous as to cause severe weakness and even death of cattle.

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.

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.
