G00-1411 Biosecurity Basics For Cattle Operations And Good Management Practices (Gmp) For Controlling Infectious Diseases, Marilyn Buhman, Grant Dewell, Dicky D. Griffin Jan 2000

G00-1411 Biosecurity Basics For Cattle Operations And Good Management Practices (Gmp) For Controlling Infectious Diseases, Marilyn Buhman, Grant Dewell, Dicky D. Griffin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide introduces cattle producers to the concept of biosecurity and provides practical management recommendations for preventing and/or containing infectious disease.

Biosecurity

The goal of biosecurity is to stop transmission of disease-causing agents by preventing, minimizing or controlling cross-contamination of body fluids (feces, urine, saliva, etc.) between animals, animals to feed and animals to equipment that may directly or indirectly contact animals. Biosecurity management practices are designed to prevent the spread of disease by minimizing the movement of biologic organisms and their vectors (viruses, bacteria, rodents, flies, etc.) onto and within your operation. Biosecurity can be very difficult to maintain …


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.

G98-1351 Proper Injection Procedures For Cattle, Dicky D. Griffin, David R. Smith, Dale M. Grotelueschen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes methods to maximize the effectiveness of injectable medications for cattle, while minimizing potential risks for the animal, the operator and the consumer. The key elements to giving proper injections are knowing why, when, where and how injectable medications should be used. Medications are commonly given to cattle as part of regular husbandry practices to improve health, control disease or increase productivity. Medications may be given by injection, by mouth (orally) or through the skin as a pour-on (topically). Injections are commonly given into the muscle (intramuscularly, or IM), under the skin (subcutaneously, or SC) or into the …

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses pricing alternatives for fed cattle, including live weight, dressed weight and grid pricing. Pricing fed cattle is becoming more complex, requiring more time to evaluate pricing alternatives and marketing cattle. Is there one best pricing method? How are live weight, dressed weight, and grid or formula prices related? This NebGuide will provide answers to these and other questions about fed cattle pricing.


G98-1352 Issues To Consider When Selling Cattle On A Grid Or Formula, Dillon M. Feuz Jan 1998

G98-1352 Issues To Consider When Selling Cattle On A Grid Or Formula, Dillon M. Feuz

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses issues and problems associated with matching cattle to the appropriate market.

Recently there has been a much greater emphasis on improving the quality and consistency of beef. Cattle producers, breed associations, feed suppliers and beef packers have initiated value based pricing methods. Grid pricing, formula pricing, and strategic alliances are examples of these new value based pricing methods. While these pricing methods may differ substantially in the carcass and management traits they seek to reward or penalize, they all have one common feature: price is established on each individual animal.

The goals of the new pricing methods …


Ec98-278 Grazing Crop Residues, Richard J. Rasby, Roger Selley, Terry Klopfenstein Jan 1998

Ec98-278 Grazing Crop Residues, Richard J. Rasby, Roger Selley, Terry Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska has an abundance of crop residue available for late fall and winter grazing. However, several factors prevent the grazing of many fields, including the location of fields in relation to the cattle, the lack of shelter or appropriate fencing and water availability. Despite these limitations, residue grazing is an important resource to many cattle operations, primarily as either a winter feed resource for maintaining the breeding herd or putting weight on cull cows. Calves weaned in the fall can also be wintered on cornstalks if appropriate supplementation is used.

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.


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.


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.


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.

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.”

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.

Preparing Bulls For The Breeding Season, Clell Bagley

All Current Publications

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.


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.


Calf Scours Simplified, Clell Bagley Jul 1997

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.
