Utilization Of Aspen Pellets As A Partial Roughage Replacement For Lactating Dairy Cows, Deborah Sharples Kipp
Electronic Theses and Dissertations
A complete switchback design using ten lactating cows divided into two groups of five was used to evaluate rations containing either (A) 30% dry matter from aspen pellets, 30% OM from corn silage, and 40% DM from a 28% crude protein· concentrate mix, or (B) 60% OM from corn silage and 40% OM from the concentrate mix, to determine if aspen could serve as a partial roughage for lactating dairy cows. All cows were at least 80 days into lactation at the start of the trial. Aspen contained on a DM basis, 1.9% crude protein, 80.3% neutral detergent fiber, 64.5% …
The Taxonomic Status Of Coyotes From Western South Dakota, Susan E. Lauzon
The Taxonomic Status Of Coyotes From Western South Dakota, Susan E. Lauzon
Electronic Theses and Dissertations
Expansion of the range of the coyote (Canis latrans) has been accompanied by numerous instances of hybridization with domestic dogs (C. familiaris). Recent studies have found a hybrid element in some wild coyote populations. The objectives of this study were to identify the taxonomic status of coyotes in western South Dakota, and to determine the degree of hybridization, if any, that is occurring between coyotes and domestic dogs in the state. Animals were collected from three areas in western South Dakota from September 1976 through January 1978. Skulls of 289 wild canids were cleaned; of these, 167 skulls from adults …

Compensatory Performance Of Swine Following Protein Insufficiency, Richard C. Wahlstrom, George W. Libal
Compensatory Performance Of Swine Following Protein Insufficiency, Richard C. Wahlstrom, George W. Libal
South Dakota Swine Field Day Proceedings and Research Reports, 1978
Pigs fed diets are deficient in any nutrients necessary for growth will generally have a reduced rate of gain and require more feed per unit of gain. Previous research conducted here at the South Dakota Agricultural Experiment Station has indicated that, if a deficient diet is fed in early growth and followed by a diet adequate in nutrients, the pig will grow at a faster rate and "compensate" for the earlier poor performance. This study was conducted to obtain additional information on the effects of a short period of protein insufficiency in early growth on gain and feed efficiency during …

Effect Of Interval Feeding On The Reproductive Performance Of Sows And Gilts, George W. Libal, Richard C. Wahlstrom
Effect Of Interval Feeding On The Reproductive Performance Of Sows And Gilts, George W. Libal, Richard C. Wahlstrom
South Dakota Swine Field Day Proceedings and Research Reports, 1978
Interval feeding (allowing ad libitum periodic consumption of feed) has been suggested as an alternative to daily feeding of sows during gestation. Less labor is involved and less equipment cost per sow is needed since, with planning, several groups of sows can be fed from the same feeders. The study reported herein was designed to evaluate the reproductive performance and the efficiency of feed utilization when sows were allowed feed three times a week during 4-hour feeding periods.

Management Of Pigs Prior To And Immediately Following Weaning At Four Weeks Of Age, George W. Libal, Richard C. Wahlstrom, Wayne E. Schiefelbein
Management Of Pigs Prior To And Immediately Following Weaning At Four Weeks Of Age, George W. Libal, Richard C. Wahlstrom, Wayne E. Schiefelbein
South Dakota Swine Field Day Proceedings and Research Reports, 1978
Baby pig management at weaning remains the weak link in most swine operations. The pig's management requirements remain as high at this stage of growth as they are when the pigs are on the show. Stress from improper nutrition, housing, temperature and ventilation as well as from establishing a new social order among regrouped pigs may affect performance and health problems of this young pig. Much is still to be learned about proper management which will minimize stress. South Dakota State University is cooperating with out Land Grant colleges in the North Central Region to evaluate the practice of intermingling …

Bacitracin Supplements For Egg Production (Ii), R. A. Nelson, C. W. Carlson
Bacitracin Supplements For Egg Production (Ii), R. A. Nelson, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1978
A previous study showed improved egg production and feed utilization from Bacitracin MD additions to a low density layer diet. Antibiotic levels shown to be effective were 10, 25 and 50 grams per ton. A level of 100 grams per ton or all levels with a high density diet were without beneficial effects.

Probiotics For Broilers, Turkeys And Laying Hens (Iii), C. W. Carlson, N. Dhillon, R. A. Nelson
South Dakota Poultry Field Day Proceedings and Research Reports, 1978
Probiotics have been one of the latest types of feed additives to be of interest to poultry producers. They are designed to improve the birds' performance by effecting a more favorable microflora in the intestinal tract. There have been numerous reports of improved rates of gain and feed utilization with broilers and turkeys and improved production and feed conversion with laying hens. Work of this type has been reported from the University of Florida, Texas A and M University and the University of Arizona.
Corn And Oats For Grower Diets And Their Effects On Subsequent Reproductive Performance, R. A. Nelson, C. W. Carlson
Corn And Oats For Grower Diets And Their Effects On Subsequent Reproductive Performance, R. A. Nelson, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1978
Previous studies at this station have shown that low protein, low density grower diets are very economical for producing layer-type pullets and that they do not affect subsequent egg production. Supplemental DL-methionine and L-lysine for 12% protein diets have been of no benefit in improving growth rate of subsequent production. This year's study compared 12% protein diets of corn and oats, alone and in combination, with a 16% protein standard corn-soybean grower diet. Table 1 shows the composition of these diets.
Effects Of Fiber Addition To Corn Diets On Fatty Liver-Hemorrgahic Syndrome, R. A. Nelson, C. W. Carlson
Effects Of Fiber Addition To Corn Diets On Fatty Liver-Hemorrgahic Syndrome, R. A. Nelson, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1978
Fatty liver-hemorrhagic syndrome continues to account for about 10% of the mortality among caged laying hens. Previous studies have shown that liver fat accumulation is suppressed when oats or wheat are used as part of the diet. Two experiments using oat hulls, wheat bran or cellulose as a fiber source were completed this past year. The first experiment involved a normal feeding regime, while the force-feeding technique was used in the other.
New Concepts In Lighting Layers, Melvin L. Hamre
New Concepts In Lighting Layers, Melvin L. Hamre
South Dakota Poultry Field Day Proceedings and Research Reports, 1978
In many ways we are still where we were 50 years ago in layer lighting. Reports in the literature prior to 1920 showed the need for long day length 14 hours of day length with natural daylight in most cases extended by kerosene or gas lanterns. While the lanterns are gone, we still follow for our most traditional layer lighting programs somewhere around a 14-hour day length.

Mercury And Selenium Interactions During Growth And Reproduction Of Chickens (Progress Report), R. J. Emerick, I. S. Palmer, R. A. Nelson, C. W. Carlson
Mercury And Selenium Interactions During Growth And Reproduction Of Chickens (Progress Report), R. J. Emerick, I. S. Palmer, R. A. Nelson, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1978
Elevated levels of mercury exist in various segments of the environment largely from past industrial and agricultural activities. Bacterial conversion of inorganic mercury to the biologically more important methylmercury promotes accumulation in animal bodies. Concentrations tend to increase as methylmercury is passed up the food chain through aquatic organisms to fish and water fowl and eventually to humans. It is this form of mercury, i.e., methylmercury, that has been implicated in egg shell thinning and lowered reproduction in birds.
