The Effect Of Management System And Breed Of Ewe On Lamb Production, W. J. Busch, A. L. Slyter

South Dakota Sheep Field Day Proceedings and Research Reports, 1983

South Dakota has a wide range of environmental conditions suitable for sheep production. These conditions determine many of the management practices utilized. Two very common systems are the farm flock similar to the Sheep Unit at Brookings and the range flock similar to the Antelope Range Station at Buffalo. The importance of increased lambing percentage and increased pounds of lamb weaned is very apparent. Crossbreeding with the Finnsheep breed known for multiple birth and the Suffolk breed known for growth is one alternative. A lifetime productivity study has been initiated to document the response of these crossbreds to the two …

The Effect Of Controlled Lighting To Enhance Breeding In Anestrous Ewes, A. L. Slyter, Steve Kappes, Richard Rogen Jan 1983

The Effect Of Controlled Lighting To Enhance Breeding In Anestrous Ewes, A. L. Slyter, Steve Kappes, Richard Rogen

South Dakota Sheep Field Day Proceedings and Research Reports, 1983

Seasonal breeding in sheep limits productivity of the ewe and creates an oscillating supply of lamb. A continuous breeding season would provide a more constant supply of lambs, allowing producers, feeders and packers to use their facilities and labor more efficiently. Induction of a fertile estrus during the normal summer anestrous period in the ewe would extend the lambing season and aid in leveling out the lamb supply. Alteration of the light : dark ratio was studied as a method to induce fertile mating during the summer in Targhee (1981) and Finn x Targhee (1982) ewes.

Alternative Feed Grains For Sheep, J. M. Thompson Jan 1983

Alternative Feed Grains For Sheep, J. M. Thompson

South Dakota Sheep Field Day Proceedings and Research Reports, 1983

South Dakota sheep producers have a number of alternative feed grains they may want to consider for use in meeting the nutritional needs of their sheep flocks. Within certain limitations, sheep are capable of utilizing all of the cereal grains produced in South Dakota. Sheep producers wanting to utilize a particular feed grain for any class of sheep need to consider the nutritive value of that feedstuff and the nutrient requirements of the animals to be fed. The typical composition of some feed grains that might be used by South Dakota sheep producers are shown in table 1.

Strategies For Increasing The Number Of Lambs Marketed Per Ewe, David L. Thomas Jan 1983

Strategies For Increasing The Number Of Lambs Marketed Per Ewe, David L. Thomas

South Dakota Sheep Field Day Proceedings and Research Reports, 1983

An objective of every commercial sheep producer should be to maximize the pounds of lamb marketed per ewe per year with the given feed, facility and monetary resources available. By increasing the pounds of lamb marketed per ewe, the relative fixed costs of maintaining a ewe are spread over more pounds of salable lamb and the efficiency of lamb meat production is improved and net income is increased. Since most producers market lambs at a constant weight, the major factor determining pounds of lamb marketed per ewe is the number of lambs raised to market weight per ewe. Presented in …

Induction Of Fertile Estrus In Early Weaned Ewes With Controlled Light, A. L. Slyter, Richard Rogen

South Dakota Sheep Field Day Proceedings and Research Reports, 1983

In order to achieve more than one lamb crop per year, it is necessary to breed ewes during lactation or following a relatively short lactation. Many times this means conception must occur during the time when ewes are normally going into anestrus or are in anestrus. This preliminary study was conducted to evaluate breeding response of ewes subjected to controlled light following weaning at 45 to 60 days postpartum.

Market Structure And Conduct Of The South Dakota Beef Industry, Annette Lorraine Clauson Jan 1983

Market Structure And Conduct Of The South Dakota Beef Industry, Annette Lorraine Clauson

Electronic Theses and Dissertations

While the South Dakota livestock producer desires the best price for his product the day it is sold, he may not always receive it. Information about alternative marketing methods and prices being paid at alternative markets is not always available. If available, this information could lead to more efficient marketing. For example, just a one dollar annual increase in market price of livestock would increase the value of commercial slaughter in South Dakota by approximately $8 million/year. An increase like this would not only benefit the livestock producer; but could result in significant impacts on the economic well-being of the …

Economic Effects Of Rural Water Systems On Agricultural Production And Productivity In Selected Counties In South Dakota, Robert Edward Green Jr. Jan 1983

Economic Effects Of Rural Water Systems On Agricultural Production And Productivity In Selected Counties In South Dakota, Robert Edward Green Jr.

Electronic Theses and Dissertations

Insufficient quantity and quality of water in South Dakota are two reasons rural residents have been turning toward rural water systems to meet their water needs. The first large rural water system was organized in 1962 to serve 700 rural residents near Rapid City. From 1962 to 1970 the growth of rural water systems in South Dakota was slow with only nine systems in operation as of 1970. Currently, the total capital investment for a large system averages $4.5 million. This amounts to an investment of $4,700 per hookup and an average monthly user charge that would exceed $20 if …

The Effect Of Varying Dietary Selenium Levels, Selenium Source And Dietary Composition On Growing Swine, Terry B. Goehring Jan 1983

The Effect Of Varying Dietary Selenium Levels, Selenium Source And Dietary Composition On Growing Swine, Terry B. Goehring

Electronic Theses and Dissertations

During the early 1900's, many stockmen in the western Great Plains suffered huge economic losses due to poisoning of their livestock through consumption of seleniferous plant material. Some were forced to discontinue raising livestock entirely and turned to grain farming. However, grain produced on land high in selenium was discounted on the market. Today, this grain marketing problem does not exist to the extent of that of the early 1900's. Selenium has more recently been recognized as an essential micronutrient for several species including swine. The Food and Drug Administration (FDA) has approved sodium selenite and sodium selenate as supplements …
