Simultaneous Selection For Milk And Beef Production Among Holstein-Friesians, L. L. Calo, R. E. Mcdowell, L. Dale Van Vleck, P. D. Miller

Department of Animal Science: Faculty Publications

A selection index combining milk and beef production traits, such that progress in aggregate economic value is maximized, was constructed for Holstein bulls. The index for milk was I_M = 1.11X₁ + .997X₂ while the index for beef trait was I_B = .008X₁ + .619X₂ where X₁ is the daughters' average lactation yield (kg) and X₂, bulls' body weight at 15 mo (kg).

The relative genetic progress from simultaneous selection for milk and beef traits with different emphasis was estimated. Expected genetic progress in beef production (body weight at 15 mo) …

Mammals From Southwestern North Dakota, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

The distribution of the mammals in the southwestern part of North Dakota and their ecological and taxonomic relationships have not been well documented. In addition to Vernon Bailey's (1927) survey of mammals of the state, based primarily upon field work conducted between 1912 and 1916, the only other principal studies dealing with the mammalian fauna of southwestern North Dakota were a preliminary report of the mammals of the state by Bailey et al. (1914) and the publication by J.A. Allen (1875) on mammals taken by the expedition that surveyed a route for the North Pacific Railway. Our studies, which were …

The Elusive Tree Quails Of Mexico, Paul A. Johnsgard

Paul Johnsgard Collection

The three species of tree quails or wood-partridges, genus Dendrortyx, of Mexico and Central America are all surprisingly large — weighing up to one pound in the case of the largest species — and have relatively long tails that result in an overall body length of from 9 to 16 inches. Their beaks are large and heavy, and are related to their abilities to tear apart and consume fruits, flower buds, and similar materials.

Three species of tree quails have been described, all of which occur in moist montane forests, especially the mist-shrouded cloud forests that occur at elevations …

Cost Of Producing Beef With Different Types And Weights Of Cattle, Danny G. Fox

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Currently, there is much interest in changing the U.S.D.A. grading standards. Some suggest that we completely eliminate the use of them. There are many reasons for this, but the major one is that many feel that the present system does not always correctly identify the most desirable carcasses. Many cattle now come to market at 15 to 18 months of age and are not marbled because of their youthfulness.

Effect Of Sex And Hormonal Compounds On Feedlot Performance And Carcass Merit Of Cattle, L. B. Embry

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Bulls gain faster and more efficiently than heifers. Removal of the gonads (bulls or heifers) reduces rate of gain, increases feed requirements and results in changes in carcass characteristics. Some hormone and hormone-like compounds are commonly used for feedlot cattle. Effects on feedlot performance have been shown to vary between male and female and between intact and castrated animals. In addition, comparative performance between males and females and response to growth promoting compounds have been shown to be influences by the diet, age and stage of fish.

Effect Of Nutrition On The Carcass Composition And Quality Of Cattle, R. L. Preston

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Beef is a highly desirable food, both nutritionally and for the pleasure it gives during its consumption. Protein of high quality is the major nutritional asset of beef, as well as supplying certain minerals and vitamins. As important as this role is, it is not the main reason that beef is the most desired of all meats. Beef is consumed because it provides great satisfaction. What then contributes of this satisfaction?

Feedlot Performance Of Bulls And The Response To Diethylstilbestrol Or Zeranol, P. J. Thiex, L. B. Embry

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

The objective of this experiment was to determine the response by feedlot bulls to DES and zeranol when administered at a younger age (about 10 months) and a lighter weight (about 500 lb.).

U.S.D.A. Quality And Yield Grades For Beef, Dan H. Gee

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

The market value of a beef carcass at the present time is primarily determined by two factors: (1) the quality of the meat (palatability) and (2) the quantity or amount of lean meat available.

Effect Of Breed On Carcass Merit, D. D. Dearborn

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Ten years ago most cattle found in feedlots in the Corn Belt and the Northern Great Plains were straightbreds representing one of the British breeds. However, with the increased use of Charolais and the importation of bulls from at least 12 other European breeds into Canada, a large variety of breeds and breed crosses is found in the feedlots at the present time. This increased variety along with emphasis on increased efficiency has caused many feeders to ask questions concerning the performance of these breeds and breed crosses. The purpose of this paper is to review research results in an …

Sulfur And Methionine Supplementation With Urea For Feedlot Cattle, B. E. Davidson, L. B. Embry

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Efficiency of urea utilization may be affected by several factors. Among these are level and source of energy, level and source of protein and amount of urea in the total diet and in the supplement. Other essential nutrients in the diet should be properly balanced. There has been a tendency in recent years to use higher levels of urea than was earlier recommended. Under some conditions, urea has been satisfactory as the only supplemental protein to diets for cattle. However, consideration should be given to likely problems of palatability and potential toxicity as well as to efficiency of urea utilization.

Corn Silage Diets For Finishing Cattle When Supplemented With Soybean Meal Or Urea And Des Fed At 10 Mg., 20 Mg. Daily Or Implanted, L. B. Embry, L. B. Dye, F. M. Byers

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Corn silage properly supplemented with protein, minerals and vitamin A forms a simple and efficient diet for growing and finishing cattle. Rate of gain will be less than for high-concentrate diets, especially during late stages of finishing. However, gain per acre of corn will be greater when fed as silage than as grain.

Toxicity Study Using Pine Sawdust As A Roughage Replacement In Gestating Beef Heifer Rations, A. L. Slyter, L. D. Kamstra

The purpose of this was to determine what difficulties might be encountered as a result of feeding raw pine sawdust to beef heifers during the last trimester of gestation.

Weaning Age And Management Systems For Fall Born Beef Calves, William Mccone

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Twenty-five registered Angus, Hereford and Shorthorn cows calved in September, 1971. The cows calved on pasture and remained on pasture until early November. From November 12 to December 29, the cows were bred for 1972 fall calves. On December 29, 1971, one-half of the calves were weaned and started on a self-fed ration. The remaining one-half of the calves were allowed to continue nursing the cows, but the calves also had access to a calf creep feeder containing the same ration used for the weaned calves. At the start of the experiment the calves were randomly divided by sex, breed …

Diethylstilbestrol, Melengestrol Acetate And Zeranol During Growing And Finishing Of Feedlot Heifers, P. J. Thiex, L. B. Embry

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Hormone and hormone-like compounds are commonly used for feedlot heifers. Effects on feedlot performance and carcass characteristics appear to vary depending on compounds used, levels administered including frequency of implanting, stage of growth and fattening, and dietary conditions. This experiment was one in a series to study the effects of melengestrol acetate (MGA) and implants of diethylstilbestrol (DES) or zeranol administered to heifers during growing and finishing or during finishing only.

Choosing Breeds And Crossbreeding Systems By Computer, C. A. Dinkel, D. D. Dearborn

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

The first report dealing with this project appeared in the Cow-Calf Field Day bulletin, August, 1972. That report presented an example to demonstrate the utility of the program for the cow-calf man. The example was based on estimates of performance traits for specific breeds under a particular environment and management situation and on market conditions existing at that time. The management system basic to the program took the weaning calf to 700 pounds in a backgrounding phase and then through a 140-day feedlot phase which was split into a 50-day growing period and a 90-day finishing period. The purpose of …

Importance Of Different Levels Of Potassium In The Diet On Whole-Body 40K Count And Muscle And Blood Potassium , R. K. Johnson, L. E. Walters, J. V. Whiteman

Department of Animal Science: Faculty Publications

The influence of three levels (1.31, 1.03 T and 0.29% K) of dietary potassium on ⁴⁰K count, blood serum and muscle tissue potassium was determined using 36 crossbred Angus-Hereford steers. A balanced 3 x 3 latin square experimental design was utilized which allowed estimates of carry-over effects of diets to be evaluated. Diets were fed for 2-week periods and appropriate samples and measurements were collected at 14-day intervals over a 60-day period. Measurements were made on steers unshrunk and after 24 hr. off feed and water.

Carry-over effect means were nonsignificant for each trait. The steers on the high …

Morphologic Time Series From A Submarine Sand Ridge On The South Virginia Coast, John F. Mchone Jr.

OES Theses and Dissertations

Submarine sand ridges several km long locally merge southward into the U. S. Atlantic coastline. Shallow (< 8m) observations of -such a ridge at False Cape, Virginia, favor a modern hydraulic origin. Time series maps show the ridge to be paralleled by a landward trough of approximately equal volume. Ridge flanks are usually steeper on the trough side.

Northeasterly winds and waves generate a coast-parallel current which funnels southward into the trough scouring it out and providing sediments for ridge aggradation. The current may be organized as a helical flow cell or cells. Bottom currents converge southward along the ridge crest causing landward transport of traction load along the crest. The trough current eventually breaches the confining ridge at the head of the trough, cutting saddles with steeper seaward slopes and producing outlying sediment fans.

The ridge and trough rest obliquely …
