Population Change In South Dakota Small Towns:1960-1970, S. G. Goss, R. T. Wagner, R. M. Dimit
Population Change In South Dakota Small Towns:1960-1970, S. G. Goss, R. T. Wagner, R. M. Dimit
Research Bulletins of the South Dakota Agricultural Experiment Station (1887-2011)
Changes of varying magnitude in small town population generate questions regarding the explanation for small town population gains and losses. Consequently, this study attempted to determine:
1. The changes that occurred in the population of South Dakota small towns from 1960 to 1970 .
2. In what way the amount of population change for small towns differed when small towns of varying size were compared with each other and when county seat communities were compared with non-county seat towns.
3. The factors that help explain the variations in population change for small towns in South Dakota from 1960 to 1970.

Protein Levels In Diets Of Sows During Gestation And Lactation, George W. Libal, Richard W. Wahlstrom
Protein Levels In Diets Of Sows During Gestation And Lactation, George W. Libal, Richard W. Wahlstrom
South Dakota Swine Field Day Proceedings and Research Reports, 1975
Research conducted during the past several years has shown that dietary protein could be reduced in gestation diets without affecting number or size of pigs farrowed. A limited amount of research has also indicated that the protein requirement during lactation may not be as great as previously recommended. However, data are limited on the long time effects during successive reproductive periods, particularly when low protein diets are fed during both the gestation and lactation periods. The North Central Swine Nutrition Research Committee agreed that this was an area where more information was needed and a cooperative project was initiated to …

Amino Acis Supplementation Of Opaque-2 Corn For Finishing Swine, Richard W. Wahlstrom, George W. Libal, John Volz
Amino Acis Supplementation Of Opaque-2 Corn For Finishing Swine, Richard W. Wahlstrom, George W. Libal, John Volz
South Dakota Swine Field Day Proceedings and Research Reports, 1975
Several experiments have shown that opaque-2 corn is superior to normal yellow corn for pigs because of its higher content of the amino acids lysine and tryptophan. Previous research at this station has shown that finishing pigs fed opaque-2 corn supplemented with lysine or lysine and tryptophan do not grow as rapidly or efficiently as pigs fed corn and soybean meal. Since we have shown that opaque-2 corn is also deficient in threonine for the young pig, this experiment was conducted to study the effect of adding supplemental lysine and threonine to a diet of opaque-2 corn, minerals and vitamins.

Effect Of Supplemental Iron Pig Starter Diets, Richard C. Wahlstrom, George W. Libal, Steven L. Robbins, James L. Girard
Effect Of Supplemental Iron Pig Starter Diets, Richard C. Wahlstrom, George W. Libal, Steven L. Robbins, James L. Girard
South Dakota Swine Field Day Proceedings and Research Reports, 1975
Iron is added to most trace mineral salts and trace mineral mixtures at low levels. However, it has been reported by some swine producers that they obtain better performance of pigs when fed a relatively high level of iron. Therefore, the objective of this experiment was to determine if there was any benefit of adding iron at levels up to 250 ppm on pig growth, feed efficiency or blood parameters.
High Protein Grains In Starter Rations, Steven L. Robbins, George W. Libal, Richard W. Wahlstrom
High Protein Grains In Starter Rations, Steven L. Robbins, George W. Libal, Richard W. Wahlstrom
South Dakota Swine Field Day Proceedings and Research Reports, 1975
High protein grains have been shown to have greater value than normal protein grains when fed to growing and finishing swine. However, limited research has been conducted using these grains in young pig starter diets. Because cereal grains primarily supply energy in the swine diet, starter diets need to be supplemented with large amounts of protein supplement in order to meet the pig's nutrient requirements. High protein grains have the ability to provide energy and a major portion of protein in the diet. Three separate experiments were conducted to determine the value of high protein grains in pig starter diets …

Moldy Feed - Good Or Bad, George Semeniuk, C. W. Carlson
Moldy Feed - Good Or Bad, George Semeniuk, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1975
Molds develop in feed in response to the nourishment they get from the feed. They develop only in the presence of air and as the result of favorable moisture conditions, which must be above a relative water vapor pressure equivalence of 65 to 70%. They develop very slowly at near-freezing temperatures and rapidly as temperatures rise. By enzyme action, they convert the energy components of the feed (carbohydrates, fats and proteins) into their own body structure with loss to the air mainly of metabolically-generated heat, water, carbon dioxide, ammonia and of fragments of their body as spores. They may or …
