Dynafac, Fat And Diethylstilbestrol For Fattening Cattle, Frank W. Whetzal
Electronic Theses and Dissertations
By nature, the ruminant animal was designed to be primarily a forage consuming animal. Under usual conditions, a large percentage of the nutrients consumed by ruminants are furnished by high-fiber feeds. The ruminant animal is relatively inefficient in the conversion of food nutrients into body tissues. Not only is the ruminant relatively inefficient in feed conversion, it is also more prone to digestive disturbances when high concentrate rations are fed. Improvement in the animal must come from effective selection and/or breeding of more efficient animals or from alteration of the physiological processes governing the animal’ metabolism which will promote increased …

Analysis Of Productivity Of Sheep Having Tails Of Different Lengths, Ivan Ralph Sundal
Analysis Of Productivity Of Sheep Having Tails Of Different Lengths, Ivan Ralph Sundal
Electronic Theses and Dissertations
This study was conducted to determine if taillessness has any effect on production characters in the South Dakota Agricultural Experiment station’s No-Tail sheep flock. Taillessness in this flock is derived from six Siberian fat-rumped sheep brought to South Dakota in 1913. These sheep did not have a tail but had a large gob of fat on either side of the rump. They were crossed with common United States breeds to develop a breed of sheep with good mutton and wool qualities as well as being tailless. Initial crossbreeding from which the No-Tail flock was established was done in 1913. Records …

Economics Of Scale In Dairying: An Exploration Of Comparative Models Of Stanchion And Loose Housing Systems, Wayne J. Schulte
Economics Of Scale In Dairying: An Exploration Of Comparative Models Of Stanchion And Loose Housing Systems, Wayne J. Schulte
Electronic Theses and Dissertations
The purpose of this study was to provide South Dakota Dairy producers and others interested in establishing large scale dairy operations with a more complete set of guide lines that will help them to determine the profitableness of expanding existing or establishing new dairy producing units. It is hoped that many management problems, encountered by existing or previous “cow pools” can either be eliminated or greatly reduced in future large scale dairy operations. An average of the four surveyed 8-140 cow dairy herds and eight model dairy systems were analyzed in this study. The three objectives were to: (1) determine …
A Proposed Rural Development Program And Its Implications For Puktia, Afghanistan, Mohammed Afzal Puktianie
A Proposed Rural Development Program And Its Implications For Puktia, Afghanistan, Mohammed Afzal Puktianie
Electronic Theses and Dissertations
The main concern of this study is to work out a community development program for the Province of Puktia, Afghanistan, which will correspond to the basic values of the existing social systems in that part of the country. People in Puktia have lived their traditional way of life for centuries and will continue to do so until changes are introduced by an outside agency. We are assuming that the people in this society cannot conintue their way of life without being affected by the progress made in the surrounding areas and other parts of the world; therefore, changes must be …

Progress Report On The The Establishment Of A Spf Herd At The Eureka Station., J.W. Mccarty
Progress Report On The The Establishment Of A Spf Herd At The Eureka Station., J.W. Mccarty
South Dakota Swine Field Day Proceedings and Research Reports, 1963-01
A herd utilizing 3 breeds in a rotation-breed- cross has been maintained at the Eureka Station since 1953. The decision was made in 1950 to continue the herd as an SPF herd to overcome disease problems. In order to "clean up" the hog facilities at the station, bred sows were moved to the Newell station in early December, 1960. During the winter and early spring for a period of six months, there were no hogs at Eureka. All housing and equipment were thoroughly cleaned.
Yeast In Growing-=Finishing Rations With Two Protein Level Comparisons, R.W. Seerley
Yeast In Growing-=Finishing Rations With Two Protein Level Comparisons, R.W. Seerley
South Dakota Swine Field Day Proceedings and Research Reports, 1963-01
In a previous report ( A.H. Mimeo Series 62-7 ) yeast culture was evaluated as an additive to good growing-finishing swine rations. Yeast did not have an effect on daily gain; however, feed efficiency was improved 6 per cent when 2 per cent yeast was included in the ration. If yeast has an enzyme action and digestion value, the yeast should improve a ration that is formulated with less crude protein than normally provided. An experiment was designed to compare levels of yeast and two levels of crude protein.
Economic Development In Taiwan, Chan Tung Li
Economic Development In Taiwan, Chan Tung Li
Electronic Theses and Dissertations
This study is a macroanalysis of economic development in Taiwan during the 1950’s. The major source of information is aggregative second data which were obtained from the Chinese publications. Taiwan’s economy is still primarily agricultural even though it has been experiencing a rapid development of industry since 1950l more than 50 per cent of the population still derives its livelihood from agricultural. The agricultural industry supplies not only foodstuffs and raw materials but also provides almost 70 per cent of the total foreign exchange from exports of agricultural commodities. Agricultural credit is an essential instrument for agricultural development; especially is …
17-Ethyl-19-Nortestosterone And 6 Methyl-17 Acetoxy-6-Progesterone In Growing-Finishing Swine Rations, R.W. Seerley
17-Ethyl-19-Nortestosterone And 6 Methyl-17 Acetoxy-6-Progesterone In Growing-Finishing Swine Rations, R.W. Seerley
South Dakota Swine Field Day Proceedings and Research Reports, 1963-01
Previous research at this station showed that 17-ethyl -19-nortestosteronte (Nilevar) significantly increased growth of female rats, but did not increase the growth of uncastrated male rats. When this hormone-like compound was fed to swine; two treatment levels increased the rate of gain of female growing-finishing pigs. Rate of gain of castrated male pigs was not improved by low levels of the compound and higher levels depressed growth. SD10363 (6 methyl-17 acetoxy-6-progesterone) is a hormone-like compound which has the possibilities as a good additive for growth stimulation in swine. The purpose of this experiment was to evaluate these compounds in swine …
Supplemental Lysine, Methionine, Fat And Fish Meal In Swine Growing-Finishing Rations, R.W. Seerley, B.A. Eason
Supplemental Lysine, Methionine, Fat And Fish Meal In Swine Growing-Finishing Rations, R.W. Seerley, B.A. Eason
South Dakota Swine Field Day Proceedings and Research Reports, 1963-01
Quality of supplemental protein in a ration for young pigs is an important consideration when formulating the ration. A good ration for young pigs should have an adequate supply of amino acids, and also the amount of amino acids should be in proper proportion to one another and to the other nutrients in the rat ion. Swine rations formulated without animal protein are usually limiting in lysine and methionine, an addition of lysine and methionine may improve the ration. A previous trial (not published) indicated better pig performance with added lysine, methionine, and fat in the ration. Fish flour, an …
Nitrates In Drinking Water, R.W. Seerley, O.E. Olson, R.F. Fritschen
Nitrates In Drinking Water, R.W. Seerley, O.E. Olson, R.F. Fritschen
South Dakota Swine Field Day Proceedings and Research Reports, 1963-01
Nitrate poisoning in livestock is a recurring problem. In ruminants the bacteria are able to convert nitrates (NO3) to nitrites (NO2) in the gastrointestinal tract. If nitrite is present in large amounts it converts hemoglobin to methemoglobin, which has little or no oxygen- carrying capacity. The result in severe cases is asphyxiation. It is not known what effects nitrates may have on swine. Nitrate levels as high as 700 parts per million (ppm ) have been found in water samples from South Dakota. The probable ways nitrates get into drinking water are by natural means and pollution. The purpose of …

The Value Of Dehydrated Alfalfa Meal And Crude Protein For Sows Kept In Confinement, R.W. Seerley, R.C. Wahlstrom
South Dakota Swine Field Day Proceedings and Research Reports, 1963-01
The second experiment on the value of alfalfa meal in rations for confined sows is reported herein. The objective of this experiment was to determine the effects of dehydrated alfalfa meal and level of crude protein on reproduction and lactation performance of female swine which were reared in confinement on concrete continuously from birth.
Proper Location Of Feeder And Waterer - Outside Versus Inside Comparisions, R.W. Seerley
Proper Location Of Feeder And Waterer - Outside Versus Inside Comparisions, R.W. Seerley
South Dakota Swine Field Day Proceedings and Research Reports, 1963-01
Has planning been adequate in regard to the best location of the feeder and waterer within the growing-finishing pen? Perhaps there is adequate planning, but most of the emphasis is placed on the convenience for the manager. Good managers know the performance of pigs, especially young pigs, is sub-optimal when the feeders and waterers are improperly located. Cold or hot temperature and other adverse weather conditions have an influence on pig performance. We have observed that our experimental pigs are extremely reluctant to go outside to eat or drink after a sudden drop in temperature during the winter. Some units …

Estrus Synchronization In Gilts, R.W. Seerley, R.D. Fritschen, D.E. Ray
South Dakota Swine Field Day Proceedings and Research Reports, 1963-01
The idea of controlling the heat period of female farm animals is not new, but intensive research in this area had not started until just a few years ago. As interest in artificial insemination increased, the desirability of controlling (synchronizing) the estrous cycle of swine became evident. It was soon discovered that boar sperms could not be frozen and still retain their fertilizing capacity in a similar manner as used for dairy cattle or beef cattle sperm. While research in this country on freezing boar spermatozoa is making progress and scientists are optimistic there has been no major breakthrough in …

Swine Housing Studies: Type Of Floors, Insulation And Methods Of Handeling Waste, R.W. Seerley, H.G. Young, J.F. Fredrikson
South Dakota Swine Field Day Proceedings and Research Reports, 1963-01
Swine housing is in an era of research, new ideas, and changes. Never before have we been more conscious of housing management and facilities for swine. Many swine producers are wondering if they should continue with the same facilities, or remodel the existing buildings, or construct a new building. If the producer decides to change or remodel, then a barrage of questions should be answered. Important considerations are: Complete confinement or pasture? What floor plan and manure handling method? Should the building be enclosed, insulated, ventilated, and how much automatic equipment? Perhaps we should make it clear in this paper …
