Feeding Hormones To Finishing Swine, R.C. Wahlstrom, J.F. Fredrikson

South Dakota Swine Field Day Proceedings and Research Reports, 1969

Diethylstilbestrol has become a rather common additive in beef cattle rations but has not been effective as a growth promotant in swine rations. Recent research has shown that combining the female hormone diethylstilbestrol (DES) with the male hormone methyltestosterone (MT) improves feed efficiency of pigs fed these rations from a weight of about 120 lb. to market. This experiment was conducted to obtain information on the effect of these hormones on growth, feed efficiency and carcass characteristics of finishing swine.

Effects Of Interval Feeding Two Types Of Gestation Rations On Reproductive Performance Of Sows And Gilts, George W. Libal, Richard C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1969

It has been established at this and other research stations that more desirable reproductive performance can be obtained in limit feeding pregnant females as compared to ad libitum feeding. There has been considerable interest in various methods of feeding in order to make the most efficient use of labor and equipment. This experiment was designed to study reproductive performance of gilts and sows interval fed two typical and yet considerably different gestation rations.

What Is The Value Of Land … To The Buyer? To The Seller?, Merlyn M. Dahl, Wallace G. Aanderud

SDSU Extension Circulars

Many land appraisers maintain that comparison or market values are the most realistic of all values because a farm is worth what it will sell for, regardless of its income earning potential. However, there are also those who feel that the market price approach should be used only as a check against the income capitalization procedure. Worksheets for estimating land value using the income capitalization procedure are included in this publication. The complete budget method may be used to estimate the value of a unit to be added to your present operation. In either case, the resulting value represents the …

Marek's Disease - Leukosis, T. E. Lucas D.V.M., James H. Bailey

South Dakota Poultry Field Day Proceedings and Research Reports, 1969

During the past few years there have been many significant new findings concerning the avian leukosis complex. Until recently these diseases were termed visceral leukosis, neural leukosis, or avian lymphomatosis. Recent research work in England and this country has clarified the cause of these diseases and they can be divided into two distinct diseases. These two diseases now known as Marek's disease and lymphoid leukosis, are caused by two different viruses. Today, the tumors and associated conditions caused by these diseases are the major disease problems of broiler and laying flocks. The loss in the United States from death and …

Nutrition Of Growing Pullets, C. W. Carlson

South Dakota Poultry Field Day Proceedings and Research Reports, 1969

Probably less is known about the nutrient requirements of growing pullets than of any other stage in the life of the chicken. Until recently, she has just been fed what we thought were her needs and she generally did quite well on quite a wide variety of regimes. This report covers a summary of the little we know.

Amino Acids And Layers, E. J. Novacek

South Dakota Poultry Field Day Proceedings and Research Reports, 1969

Studies conducted over a four-year period with low protein diets for caged layers are summarized in Table 1. The data indicate that the 9.4 percent protein diet with added methionine, lysine and tryptophan would support a rate of egg production nearly the same as a 15.4 percent protein diet. The rate of production from a 12.4 percent protein diet was not improved by raising the protein level to 15.4 percent. Further addition of protein after the amino acid deficiency has been corrected should only cause an increase in loss of nitrogen in the excreta.

New Tools For Research, Walter Morgan

South Dakota Poultry Field Day Proceedings and Research Reports, 1969

Between the years of 1900 and 1930 good hen flock records were maintained for egg production. During this same time, a technique for keeping a record of eggs laid by individual hens in a flock was developed. The trapnest provided a new tool for the poultry breeder. With the accumulation of dependable egg-production records, it became possible to calculate flock averages, breed averages, family and individual averages. The simple tool for trapping the hen in a nest, and thus permitting identification of her individual egg and her total number of eggs, was necessary before an educated program in selection was …

Economical Turkey Broiler Diets, E. Guenthner, C. W. Carlson

South Dakota Poultry Field Day Proceedings and Research Reports, 1969

Approximately 600 large white and 150 broiler type poults were started, intermingled, in battery brooders. At three weeks of age, the poults were transferred to pens with crushed corn cob litter on the floors. Each poult had 2 sq. ft. of floor space. When the broilers were sold at 15 weeks, the remaining poults each then had 2.5 sq. ft. of floor space. The large turkeys were sold at 24 weeks of age. The turkeys were grown in complete confinement in a windowless house with a cement floor.

A surveillance program was conducted during June 1968 through June 1969 to determine the important causes of mortality in certain South Dakota layer flocks that experienced reasonably normal mortality.

Livestock Auctions In South Dakota: An Economic Analysis, R. L. Beck, D. K. Bendt

Research Bulletins of the South Dakota Agricultural Experiment Station (1887-2011)

In the early stages of development of livestock auctions, transportation and production conditions largely limited the distance from which firms could procure livestock. As a result most auctions were too small to attain any significant degree of efficiency in operations. In recent years, the continual development and improvement in roads and truck transportation, along with the trend toward larger producers, have reduced the time and cost of transporting livestock. As a result, procurement areas for auction firms have increased. With larger supply areas, the potential volume of auction firms has increased. With this increase in volume should come greater operational …

Social And Economic Impact Of The Pollock-Herreid Irrigation Unit, F. F. Kerr

SDSU Extension Fact Sheets

Development of the Pollock-Herreid Irrigation Unit in Campbell County would create a stable agricultural economy and tend to inspire a feeling of security among the people of the area. This security is not, in itself, measurable in dollars. It is possible however to predict, with reasonable accuracy, what changes will gradually take place after the Pollock-Herreid Unit is in operation and to predict what these changes will mean to the dollar value of the economy. The changes that take place, in turn, contribute to stability and greater security. The estimated changes outlined in this publication are based on what has …

Safe Rural Water Supplies, F. F. Kerr, John Hatch

SDSU Extension Circulars

A safe water supply source should be obtained from an uncontaminated water-bearing formation or from a properly located and constructed farm pond. The water should be pleasing to drink, bacteriologically and chemically safe, and delivered through a system which will keep it safe at all times. To accomplish this, the water source and system must be located and constructed to keep out surface and near-surface contamination, or be continuously treated.

Chemical Weed Control In Crops, Cooperative Extension South Dakota State University

SDSU Extension Fact Sheets

Chemical weed control is a valuable supplement to and not a replacement for such sound management practices as using clean seed, proper seedbed preparation, good rotations, timely cultivations and crop competition. If we rely solely on chemicals and neglect standard management practices, resistant weeds will increase.

An Economic Analysis Of Ranch Organization In Central South Dakota, Herbert R. Allen, Rex D. Helfinstine

Agricultural Experiment Station Technical Bulletins (1939-2011)

A fundamental economic problem facing ranchers in central South Dakota concerns the allocation and use of scarce resources in such a way as to attain the most profit. This study was concerned with the optimum organization of a typical ranch on the Williams-Tetonka-Cavour soil association in central South Dakota. The major objectives were: (1) to present alternative ranch plans for maximizing net returns under varied capital levels and efficiency levels; (2) to determine a profit maximizing land use program from among the many pasture improvement programs and pasture management systems for beef production on a typical ranch; (3) to estimate …
