1992 Beef Cattle Report, Darrell W. Nelson

Nebraska Beef Cattle Reports

Economic efficiency of beef production to weaning and to slaughter was estimated in three groups, different in milk available (low, medium, and high) to the calves but the same in growth potential. Efficiency was the ratio of income to expenses. Income was derived from cull cows and calves at weaning or carcasses of calves fed to slaughter. Feed and non-feed expenses for the cowherd and for calves to weaning or to slaughter were included. Efficiencies were estimated assuming observed reproductive rates and energy requirements for maintenance, as well as for equal reproductive rates and equal requirements for maintenance in the …

A two-year study tested the hypothesis that growth rate interacts with bull exposure to influence age at puberty in heifers. Heifers exposed to sterile bulls and fed to achieve a high growth rate (1.8 lb/day) attained puberty 73 days earlier than heifers not exposed to bulls and fed to a moderate growth rate (1.3 lb/day). Heifers exposed to bulls and fed to achieve a moderate growth rate attained puberty at ages similar to heifers not exposed to bulls and fed to a high growth rate. Furthermore. heifers receiving these two treatments attained puberty 23 days earlier than heifers not exposed …

The Incidence Of Cryptosporidial Infections In Nebraska Dairy Calves, Douglas Lee Varner Jul 1986

The Incidence Of Cryptosporidial Infections In Nebraska Dairy Calves, Douglas Lee Varner

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Within the last decade a new etiologic agent has been identified as a possible cause of diarrhea in humans and domestic animals—that being the protozoan parasite Cryptosporidium. The purpose of this study was to determine the incidence and distribution of Cryptosporidium in the state of Nebraska, to determine if Cryptosporidium occurs more frequently in association with other enteropathogens and to determine about the relation of scouring in the calves to infection with Cryptosporidium. A total of 620 fecal samples from 334 dairy calves from 71 herds in Nebraska were examined for cyptosporidial oocysts using the Sheather’s sugar flotation …

Nebraska Beef Cattle Reports

Weighing steers three consecutive days at the beginning and end of the trial reduced variation and increased the probability of detecting a difference in daily gain and gain/protein ratios between treatments when compared to a standard weighing method (once at the beginning and once at the end of the trial). Regressing 1 initial, 1 final and 11 weekly weights also decreased variation and increased the probability of detecting treatment differences compared to the standard method, but was more variable than using three weights at the beginning and end of the trial.

Young, growing steers and lambs supplemented with natural protein …

Growth Rate Of Thoroughbreds: Effect Of Age Of Dam, Year And Month Of Birth, And Sex Of Foal, R. L. Hintz, H. F. Hintz, L. Dale Van Vleck Jan 1979

Growth Rate Of Thoroughbreds: Effect Of Age Of Dam, Year And Month Of Birth, And Sex Of Foal, R. L. Hintz, H. F. Hintz, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Weight, height, and cannon bone measurements were obtained on 1,992 Thoroughbred foals. Colts were heavier than fillies at birth and the differences increased with age. Dams under 7 years of age and older than 11 years had foals of lighter weight at birth than mares 7 to 11 years of age and the differences persisted at 510 days of age. Foals born in April, May, or June were heavier than foals born in January, February, or March. Year of birth also influenced body weight. The trends for height at withers and cannon circumference were similar to those of body weight.

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 Philosophy Of Drenching Sheep In Western Australia, G C De Chaneet Jan 1977

The Philosophy Of Drenching Sheep In Western Australia, G C De Chaneet

Journal of the Department of Agriculture, Western Australia, Series 4

Sheep of all classes are drenched more or less regularly throughout the agricultural areas of Western Australia.

Much of the drench is wasted because it is used in the wrong circumstances. This situation is probably a result of poor understanding of drenching.

This article discusses the philosophy of drenching and attempts to relate this to the epidemiology of parasitism as it is currently understood.

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 …


Calf Diarrhea (Scours): Reproduced With A Virus From A Field Outbreak, C. A. Mebus, N. R. Underdahl, M. B. Rhodes, M. J. Twiehaus Mar 1969

Calf Diarrhea (Scours): Reproduced With A Virus From A Field Outbreak, C. A. Mebus, N. R. Underdahl, M. B. Rhodes, M. J. Twiehaus

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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 …

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 …

49th Annual Feeders Day Progress Report: Improving Beef Production Through Nutrition And Management, E. F. Frolik, A. W. Epp

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 …


Swine Brucellosis: How You Can Eradicate It Jan 1961

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 …

48th Annual Feeders Day Progress Report: Improving Beef Production Through Nutrition And Management, W. V. Lamber, E. F. Frolik

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.

Leaflet No 2024 - Mulesing And Tail Stripping. Proved Measures For The Control Of Crutch And Tail Strike In Sheep, J Reilly

Bulletins 1 - 2999

FOR many years, the losses from blowfly strike on the crutch and tail areas imposed a tremendous economic burden on the Merino sheep industry in Australia. Today, the modified Mules operation and the tail-strip treatment have provided a convincing answer to this menace. Breech wrinkles encourage strike, and although as a long-term policy, efforts are being made to eliminate wrinkles by breeding for plainness of breech, it is of the utmost importance to give the sheep IMMEDIATE protection by the most effective methods available.

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 Oct 1929

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.
