Retail value of wholesale meat cuts is influenced by quality and the proportion of lean, fat and bone. Wholesale cuts vary widely in value; for example, loins and ribs sell for more than rounds, rounds more than chucks, and chucks more than flanks, plates, or briskets. This value difference has prompted many attempts to find breeding and feeding systems that will increase the proportion of high-priced cuts.
Results shown here characterize the composition of carcass wholesale cuts from 14 breed combinations that were part of a cattle germ plasm evaluation program at the U.S. Meat Animal Research Center, Clay Center, …

The use of high concentrate rations in finishing cattle has led to a rather high loss of livers due to abscesses.
The 1967 Statistical Summary of the Federal Meat Inspection Service of the USDA indicated the total number of cattle inspected was 27,859,980. Of these, 9.6% were condemned because of liver abscess. Considering the value of a liver to be about $3, the estimated loss to the industry because of condemnatIon due to abscess would be over $8 million annually.
The incidence of liver abscesses increases as the roughage level in a finishing ration decreases below 5% (Table I). The …

Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Neonatal calf diarrhea typical of that seen in field cases was produced in colostrum-deprived calves by inoculating either feces or bacteria-free filtrates via the duodenum, orally, or by a spray (aerosol). Three calves, kept free of E. coli, developed severe diarrhea following inoculation with a bacteria-free filtrate. Intense fluorescence in the epithelium of sections of small intestine from two experimental calves was observed following staining with ftuorescein-labeled gamma globulin produced with viral antigen prepared from the feces of two experimental diarrhetic E. coli-free calves. Fluorescing cells were also present in the feces of experimental and field cases of neonatal …

Oral feeding of stilbestrol or implanting with stilbestrol or Synovex has resulted in increased weight gain and efficiency of gain for cattle fed finishing rations.
Combining oral feeding or stilbestrol with implanting did not give increased performance above that obtained from oral stilbestrol alone in two tests. Implanting cattle fed oral stilbestrol at the start of the feeding program with either stilbestrol or Synovex gave a similar pattern of performance to that obtained from oral stilbestrol alone.

Many beef cattle breeders in the United States and other countries are following the progress of the selection experiment at the Fort Robinson Beef Cattle Research Station, Crawford, Nebraska. Three lines of Hereford cattle from the same genetic foundation are under selection. Line 21 is selected for 200-day weight. Line 22 is selected for yearling weight. Line 23 is selected for an index combining yearling weight and a score for muscling and fat thickness.
Each line is operated as a closed herd so it will be possible to determine how much improvement in economic traits can be made by selecting …

Beef carcass evaluation work is designed to obtain production and carcass data on bulls, steers and heifers. One objective is to evaluate sex effects on growth and carcass traits. Another is to determine if sires rank the same in growth and carcass traits on their bull, steer and heifer progeny.
Preliminary results from the 1963 slaughter groups were reported in the 1964 Beef Cattle Progress Report. This report covers averages of 1963 and 1964 results. Results both years were similar.

Efficiency of sugar beet farming can be improved by feeding beet top silage to livestock.
In two recent trials at the Scotts Bluff Experiment Station lambs fed unwilted beet top silage as the only roughage gained significantly faster than lambs fed corn silage.
Amounts of concentrates were comparable (Nebraska Experiment Station Quarterly, Fall, 1962).
This experiment compared the feeding value of a complete mixture of unwilted beet tops and concentrate added at the time of ensiling, with beet top silage and concentrate handled separately. A conventional corn silage and concentrate ration was used as a control.
Results showed that a …

Shipping fever is a respiratory disease "complex" of cattle. The disease causes extensive economic losses from death, loss of physical condition, inefficient feed utilization and treatment expense. The annual loss from this disease in the United States has been estimated to be $25,000,000.
In many respects shipping fever is similar to respiratory diseases of humans. It may occur in any season of the year, but is most common in the fall and early winter. Although any age animal may be infected recently weaned calves and feeder cattle which have just been moved from the range to feedlot are most susceptible.

Feeding pastured calves protein supplements weekly instead of daily during the winter made little difference in either winter or summer gains, according to research results to date.
Two sources of protein were used in the trial. (I) Second cutting alfalfa hay was fed at the rate of four pounds per head daily. One group of calves was fed four pounds per head daily and one group was fed 28 pounds per head once each week. (2) Forty percent protein, pellets or cake, was fed at the rate of one pound per head daily. One group was fed one pound per …
Swine Brucellosis: How You Can Eradicate It
Swine Brucellosis: How You Can Eradicate It
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Swine brucellosis is a bacterial disease that affects swine, other domestic animals, and humans. Severe exposure causes the disease in cattle, dogs, cats, and poultry. The disease can spread from one species of animal to another, and from animals to humans. However, it does not normally spread from one human to another, or from humans to animals. The disease costs the swine industry about $10 million a year. Losses due to human infection cannot be estimated. Although human brucellosis, or undulant fever, is difficult to diagnose-especially in mild cases-a total of 892 cases were documented in the United States in …

Nebraska Beef Cattle Reports
The science of nutrition has come into its own in the last few years. Greater recognition of the value of protein, the identification of new nutrients and the awareness of the importance of nutrition to health have been part of this trend.
In this new era in nutrition, beef has been found to be one of our most nutritious foods. Not only does it contain a generous amount of protein, but its protein is of high quality, too. In addition, beef supplies important minerals such as iron and phosphorus, which contribute to healthy blood and sturdy bones. The essential B …

Nebraska Beef Cattle Reports
As we start a new decade it is appropriate to ponder for a moment on where we have been and where we go from here.
The past ten years have seen significant changes in all phases of animal agriculture. Probably the most spectacular changes came in the area of nutrition. During the past ten years significant advances were made in our knowledge on mineral and vitamin nutrition. Additional facts on the old problem of the ratio of concentrates to roughage have been added. Ways of supplementing poor quality roughage to obtain optimum production were learned.

Swine Erysipelas. Revised Edition Of Research Bulletin 84, L. Van Es, C. B. Mcgrath
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Because of the more or less frequent occurrence of swine erysipelas on Nebraska farms it seemed proper that information on this subject be made available in the form of a Station publication, especially written to serve as a reference for veterinarians, who naturally are first appealed to when an as yet relatively strange disease appears among a herd of swine. Hence the text is written in a technical form for the sake of precision. In the preparation of the text the literature of countries in which for many years the disease has constituted a permanent problem has been freely consulted. …

The principal purpose of the investigation reported here was to evaluate, if possible, hygienic measures, and in addition to gather whatever information might become available pertaining to the relation of certain disorders to a given poultry population after its exposure to their specific etiologic factors. The experiments were conducted on a piece of ground upon which poultry had not been maintained for many years, if ever.

Nebraska Agricultural Experiment Station: Historical Circulars
It is not infrequent that considerable difficulty is encountered in raising calves with limited amounts of milk or none at all. Requests for information on calf gruels, mixed grain feeds, and commercial supplements are frequent enough to make a short circular upon this subject seem desirable. Furthermore, as the more diversified agricultural program gets under way these requests are increasmg.

The Abortion Problem In Farm Live Stock, L. Van Es
Nebraska Agricultural Experiment Station: Historical Circulars
Successful animal husbandry is fundamentally dependent on the efficient reproduction and preservation of young stock. Not only are losses among the latter a prolific source of direct economic damage, but they also tend to create an equally serious disadvantage of a more indirect nature. Losses of young animals, unless a reduction of our live stock population can be tolerated, necessitate the setting aside of a larger number of females for purely reproductive purposes than would be required if such losses were not a factor.

On The Nature And Cause Of "The Walking Disease" Of Northwestern Nebraska (Necrobiosis Et Cirrhosis Hepatis Enzootica), L. Van Es, L. R. Cantwell, H. M. Martin, J. Kramer
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The "walking disease" of Northwestern Nebraska is essentially an enzootic necrobiosis and cirrhosis of the liver due to a toxic agent and does not materially differ from similar disorders occurring in other regions or countries. The disease affects horses and cattle but it is most commonly encountered in the former. The disease in all its clinical and pathological manifestations may be reproduced with the utmost fidelity by the feeding with plants of Senecio riddellii.

An Inquiry Into The Cause Of The Increase Of Tuberculosis Of Swine, L. Van Es, H. M. Martin
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The great increase in the number of swine found to be tuberculous presented a problem, the solution of which appeared to be desirable before adequate control measures could be devised or recommended. In the hope that a solution of the problem may be found this station undertook an investigation and attempted by experimental inquiry to determine the infection type of the tuberculosis associated with the animals which constituted the bulk of the retentions. In view of the apparent increased incidence and spread of tuberculosis among poultry in a large hog raising section, of which Nebraska forms a part, the experimental …
