Protocol For Trichomonas Diagnosis In Cattle For Utah, Bruce King, Kerry Rood

All Current Publications

Trichomoniasis, caused by the protozoan Tritrichomonas foetus, is a serious reproductive (venereal) disease found in some Utah cattle herds. Diagnosis of trichomoniasis is made when trichomonad organisms are detected in the smegma or preputial flush samples of bulls, or the uterine/vaginal fluids of cows


Processed Corn Silage Effects On Digestibility And Production Of Growing Beef Replacement Heifers, Dale Zobell, Ken Olson, Randall Wiedmeier Feb 2004

Processed Corn Silage Effects On Digestibility And Production Of Growing Beef Replacement Heifers, Dale Zobell, Ken Olson, Randall Wiedmeier

All Current Publications

Forage is generally the principle feedstuff in feedlot diets for growing cattle and, as such, its nutritive value will determine weight gain, feed intake and feed efficiency. In feedlot diets for growing cattle, corn silage can constitute up to 60% of the diet (DMB).

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 Jun 2001

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.

Vaccines are an important tool to use in herd health programs for the protection of animal health. However, vaccines often do not protect health by themselves, and should be used in conjunction with good management practices. The timing of vaccination and selection of product type are important considerations.


Helping Dairy Producers Reduce The Scc, Clell Bagley Jan 2000

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.


Abortion In Cattle, Clell Bagley Oct 1999

Abortion In Cattle, Clell Bagley

All Current Publications

Abortion is the premature expulsion of the fetus from the dam and usually occurs because the fetus has died in-utero. If death occurs at 1-2 months of gestation, it is usually termed “early embryonic death.”


Colloidal Silver Not Approved For Treating Animals, Clell Bagley Aug 1997

Colloidal Silver Not Approved For Treating Animals, Clell Bagley

All Current Publications

FDA has received reports that products containing colloidal silver are being promoted for use in the treatment of mastitis and other serious disease conditions of dairy cattle, as well as for various conditions of companion animals. For example, FDA’s Center for Veterinary Medicine has received reports from the Agency's regional milk specialists and State inspectors that colloidal silver products have been found on some dairy farms.


Ammonia Toxicity In A Herd Of Beef Cattle, Clell Bagley Jul 1997

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.


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.”


Staph Mastitis: Herd Control Program, Clell Bagley Jul 1997

Staph Mastitis: Herd Control Program, Clell Bagley

All Current Publications

Mastitis caused by Staphylococcus aureus is a major problem for some dairy herds. It causes high Somatic Cell Counts (SCC), reduces milk quality, and may cause a loss of milk market. It limits milk production for the herd, reduces efficiency, and continues to spread to other cows.


Mastitis Prevention Program, Clell Bagley Jul 1997

Mastitis Prevention Program, Clell Bagley

All Current Publications

A great deal of money and effort have been expended over the years to find methods for control of mastitis in dairy cows. Both European and U.S. workers have developed programs of prevention that are very similar. These preventive programs require implementation of the seven basic procedures outlined below. It has been shown repeatedly that this programs works.


Halogeton Toxicity In Cattle, Clell Bagley Jul 1997

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.


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.


Controlling Internal Parasites In Utah Cattle, Clell Bagley Jul 1997

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.


Infectious Cattle Diseases And Vaccines, Clell Bagley Jul 1997

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.


Updating Your Herd Health Plan, Clell Bagley Jul 1997

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.


Pinkeye, Clell Bagley Jul 1997

Pinkeye, Clell Bagley

All Current Publications

Pinkeye is the common term for Infectious Bovine Keratoconjunctivitis (IBK). This terminology describes a disease condition of cattle which is infectious in nature and causes an inflammation of the transparent cornea, the sclera (“white”) of the eyeball and the conjunctiva (inside lining membrane) of the lids.


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.

Yew Had Better Watch Out!, Clell Bagley, Kip Panter

All Current Publications

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.


Bovine Respiratory Disease, Clell Bagley Jan 1997

Bovine Respiratory Disease, Clell Bagley

All Current Publications

Disease of the respiratory tract is a major problem for cattle and it continues to cause serious economic losses for producers. Bovine respiratory disease (BRD) causes increased death losses as well as medication costs, labor, and lost production. Many different infectious agents may cause similar clinical signs. Multiple agents are often involved in the development of BRD.
