South Dakota Poultry Field Day Proceedings and Research Reports, 1974
A low protein series of diets were fed to 600 male and 300 female Large White poults with the protein ranging from a 23% starter to a 12% finisher. Three copper treatments were used, normal (8-12 ppm) and two sources of copper (120 ppm) from copper sulfate and copper oxide. Each copper treatment was fed with the recommended levels of "4-nitro" and ipronidazole for blackhead control. The poults were started in electric batteries for 2 weeks and then moved to floor pens with cob litter and gas brooders. The hens were marketed at 15 weeks and the toms at 24 …

Some Effects Of Low Protein Grower Diets Fed With Or Without Antibiotics On Growth Rate And Subsequent Reproductive Performance, R. A. Nelson, C. E. Holmquist, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1974
Several studies at this station have shown that Leghorn-type pullets can utilize diets as low as 10 to 12% protein during the growing stage (8 to 20 weeks) without adversely affecting their subsequent reproductive performance. Mortality during the growing and laying period was either unaffected or decreased. However, low protein, low-energy fed pullets tend to consume 1 to 2 pounds more feed during the growing period. As a result, pullet growers have tended to continue using the higher protein and higher energy diets. Two studies have been completed and another is under way to further evaluate low protein grower diets …

Amino Acid Additions To A 12% Protein Corn-Soy Diet For Layers, A. B. Kashani, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1974
Earlier studies at this station have indicated that, when a 16% protein, cornsoybean meal diet is diluted to 10.8% protein with glucose and supplemented with 0.15% DL-methionine, 0.19% L-lysine, 0.2% DL-isoleucine and 0.04% DL-tryptophan, 71% egg production was obtained. However, the following supplements were without further effects—0.1% DL-threonine and 0.05% DL-valine with 0.25 and 0.5% glycine alone and in all combinations or with glycine and glutamic acid each at 0.25, 0.5 and 1% levels.
Performance Of Irradiated Lines, Walter Morgan
Performance Of Irradiated Lines, Walter Morgan
South Dakota Poultry Field Day Proceedings and Research Reports, 1974
Animal resistance to outside or to environmental stress may come from several sources. Resistance may result from an administered protector, either external or internal as with vaccinations, or the resistance may be due to some internally controlled body mechanism, as with natural immunity. If the resistance results from the latter, we refer to it as inherent or genetic resistance. At the South Dakota Experiment Station, we have initiated studies with both kinds of resistance. The progress with genetic resistance is the topic for discussion in this report.

Flock Record Summary, Phillip E. Plumart, Boyd J. Bonzer
South Dakota Poultry Field Day Proceedings and Research Reports, 1974
A computerized flock record keeping system has been in use at South Dakota State University since 1965. A report is computed and published monthly from data received from approximately 60 flockowners. The records of those flocks completing their laying cycle during the calendar years of 1968, 1969, 1970, 1971, 1972, 1973, and through June of 1974 are summarized in Table 1.

South Dakota Poultry Field Day Proceedings and Research Reports, 1974
Much has been said and written about the American diet and its possible effects on heart disease. There are those who contend that major changes must be made in dietary patterns of the American people, while others say that little evidence is available to link diet with heart disease. Researchers will, agree that it is hard to maintain scientific objectivity when human welfare is considered. Therefore, when conducting research of this nature, the ultimate truth is required.

Effects Of Feed Restriction And Energy-Protein Relationships On Egg Production, E. Guenthner, C. W. Carlson
Effects Of Feed Restriction And Energy-Protein Relationships On Egg Production, E. Guenthner, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1974
Feed restriction is frequently used in handling broiler breeder hens to maximize performance and to economize feed costs. Some attempts have been made to apply this technique to egg laying strains. In the test to be reported here, 80 groups (24 hens per group) of caged egg-production strain pullets were fed four diets on a restricted and full-fed basis. The four diets provided two levels of protein (13.9 and 18.3%) and two levels of energy (2500 and 3300 Cal ME). Feed restriction was accomplished by covering the feeders at 3:00 PM and removing the covers the following morning at 7:00 …

Effects Of Copper On Turkey Lipids And Palatability, C. W. Carlson, E. Guenthner, R. A. Nelson, Dorothy Deethardt
South Dakota Poultry Field Day Proceedings and Research Reports, 1974
Large Broad White turkeys were fed from one day of age to market weight on low protein diets with and without two forms of copper (sulfate and oxide) to supply 120 ppm. As reported previously (A.S. Series 73-22 and A.S. Series 73-25), copper enhanced growth but had no consistent effect upon fatty acid composition.
Fatty Liver-Hemorrhagic Syndrome As Affected By Fat, Choline And Biotin Supplementation, R. A. Nelson, C. C. Chah, C. W. Carlson
Fatty Liver-Hemorrhagic Syndrome As Affected By Fat, Choline And Biotin Supplementation, R. A. Nelson, C. C. Chah, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1974
Fatty liver syndrome, now more commonly known as fatty liver-hemorrhagic syndrome (FLHA) , has become an increasing problem in recent years, especially in cage-type laying operations. It seems to occur in flocks that are apparently healthy and in good laying condition. Symptoms characteristic of the disease are about a 25% increase in body weight along with a 30% or more decrease in production, an increase in mortality and excessive abdominal and liver fat that leads to hematomas of the liver.
Effects Of Mercury On Production And Reproduction Of Laying Hens--Second Egg Laying Cycle, R. J. Emerick, C. W. Carlson, R. A. Nelson, C. E. Holmquist
Effects Of Mercury On Production And Reproduction Of Laying Hens--Second Egg Laying Cycle, R. J. Emerick, C. W. Carlson, R. A. Nelson, C. E. Holmquist
South Dakota Poultry Field Day Proceedings and Research Reports, 1974
Hens fed diets containing various levels of two mercury sources from the time of hatching were studied during a second laying cycle. Early growth data and data pertaining to the first laying cycle were reported in the 1973 Poultry Day reports (A.S. Series 73-18). It was concluded from these earlier phases of the study that inorganic mercury at levels up to 20 ppm in the diet does not influence growth or egg production, quality and hatchability. Methylmercury at levels of 2.5 ppm or less also appeared to be well tolerated with no visible harmful effects. However, detrimental effects of higher …
Diethylstilbestrol, Zeranol Or Synovex-S Implants For Growing Steers, L. B. Embry, W. S. Swan
Diethylstilbestrol, Zeranol Or Synovex-S Implants For Growing Steers, L. B. Embry, W. S. Swan
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1974
Numerous experiments during the past several years have shown that implanting feedlot steers or heifers with diethylstilbestrol (DES), zeranol or Synovex results in an increase in rate of gain with improved feed efficiency. Comparisons between the three products under various conditions are more limited. Therefore, comparative effects of DES, zeranol and Synovex-S were tested in a growing experiment where steers were full-fed corn silage with 2 lb. per head daily of protein supplement for a period of about 3 months.

Pine Sawdust As A Roughage Substitute In Beef Finishing Rations, L. D. Kamstra
Pine Sawdust As A Roughage Substitute In Beef Finishing Rations, L. D. Kamstra
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1974
Previous reports discussed toxicity trials with untreated sawdust, indicating no toxicity to ruminants when fed up to 25% of the ration. The low digestibility (7-10%) of softwood sawdust produced from the mills in western South Dakota limits its usage as a major ration component. The objective of this experiment is to demonstrate the usage of ponderosa pine (Pinus ponderosa) sawdust as a nonnutritive roughage component in beef finishing rations.

Quality Measurement Of Hay Stored By Large Hay Packaging Systems, L. D. Kamstra, R. Schrempp, P. Turnquist, C. Johnson
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1974
The purpose of this study was to determine to what extent large hay package storage retained the initial forage quality by measurement of seven quality parameters over an extended period. The Hesston 60 and Haybuster 1800 were used as examples of hay packaging systems for study.
Soybean Meal And Urea Supplements With Corn Silage At Various Stages Of Feeding For Growing Cattle, L. B. Embry, W. S. Swan
Soybean Meal And Urea Supplements With Corn Silage At Various Stages Of Feeding For Growing Cattle, L. B. Embry, W. S. Swan
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1974
Calves weaned and fed supplements containing urea generally have a period of reduced performance in comparison to those fed soybean meal supplements. The period of reduced gains may last for 3 to 4 weeks for calves unapted to urea, but it may vary in legnth and severity depending upon the level of urea, energy concentration of the diet, age of cattle and stresses to which subjected prior to arrival and at the feedlot. The period of reduced performance appears to become of lesser importance with increasing age of the cattle.

Protein Supplementation For Finishing Cattle Fed All-Concentrate Or Low Roughage (Alfalfa) Diets, L. B. Embry, W. S. Swan
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1974
The experiment reported here was conducted to determine the need for supplemental protein in all-concentrate diets composed largely of corn grain and in diets with low levels of roughage (4 lb. of alfalfa haylage). Cattle fed supplements with soybean meal or urea were compared to those fed similar diets without supplemental protein to the corn or corn and alfalfa haylage.
