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 …

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.

Weather patterns greatly impact feed supplies for almost all areas of Utah. Both grazing and harvested feed supplies are usually reduced with drought conditions.

Health Programs Which Improve The Marketability Of Calves, Clell Bagley

All Current Publications

The “winds of change” have the potential to drastically change the marketing of beef calves in the next few years.

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.

Dystocia (Difficult Lambing), Clell Bagley Jul 1997

Dystocia (Difficult Lambing), Clell Bagley

All Current Publications

If the flock is lambed on the range, assistance is not given to individual ewes. Catching those needing help causes so much disruption of ewes with normal lambs and results in so many orphans, it is detrimental. One of the primary advantages of shed lambing a range flock is being able to better assist during birth and those first crucial hours of life.

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.

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.
