Processing Of Oats In Limited Grain Rations For Wintering Calves, L. B. Embry, D. E. Overbay
Processing Of Oats In Limited Grain Rations For Wintering Calves, L. B. Embry, D. E. Overbay
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1976
Hay fed to appetite along with 5 to 6 lb. of grain is a common ration for growing calves for herd replacements or later feedlot finishing. Feeding could be simplified and costs reduced by feeding grain in the whole form. Studies with corn have often shown some improvement in weight gain and feed efficiency from processing the grain for cattle where the roughage level exceeds about 20% of the dry ration. Sorghum grain, wheat and barley appear to benefit more from processing than does corn grain.

Rumesin For Growing And Finishing Cattle, L. B. Embry
Rumesin For Growing And Finishing Cattle, L. B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1976
Much of the research with feedlot cattle has been devoted to studies of ways to improve feed utilization. A large portion of feed energy, and also protein, available to the ruminant results from microbial fermentation in the rumen, or rumen-reticulum. Environmental conditions maintained in the rumen are important in the rate of fermentation and the resulting end-products. Numerous experiments have shown that volatile fatty acids (VFA)--major ones being acetic, propionic and butyric produced by microbial fermentation in the rumen play major roles in energy metabolism of ruminants.

Utilization Of Crop Residues And Highly Lignified Waste Products In Wintering Rations For Beef Cows, L. D. Kamstra
Utilization Of Crop Residues And Highly Lignified Waste Products In Wintering Rations For Beef Cows, L. D. Kamstra
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1976
Although residues and waste fiber can be fed in many types of ruminant rations at low levels as a replacement for the forage, greater usage can probably be found in maintenance or wintering rations. A crop residue or waste material is no better than its available nutrient composition. How closely this nutrient composition will meet the requirement of animals determines how the material can be used and what supplemental feeds are required. The nutrient requirement of 1,100 lb. dry pregnancy mature cows in the middle third of pregnancy could be used as a basis for requirements for a maintenance or …
Roughage Quality And Protein Supplementation With High-Concentrate Rations For Finishing Cattle, R. N. Gates, L. B. Embry
Roughage Quality And Protein Supplementation With High-Concentrate Rations For Finishing Cattle, R. N. Gates, L. B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1976
Feedlot cattle have been shown to make high rates of gain with low feed requirements when fed all-concentrate rations during finishing periods up to 6 months or more. However, some roughage has frequently been reported to improve weight gain and to reduce digestive problems associated with all-concentrate rations. Roughage levels of 8 to 10% have appeared adequate for these purposes and are considered to be about optimum on basis of weight gain and feed efficiency. Questions are often raised as to the importance of roughage quality when included in rations at these low levels.
Whole Or Rolled Corn Grain Fed At Various Levels To Cattle On Pasture, L. B. Embry
Whole Or Rolled Corn Grain Fed At Various Levels To Cattle On Pasture, L. B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1976
Past experiments at this station with cattle on pasture have involved carious levels of grain feeding. Levels of corn grain varied from none to a full feed averaging about 14 lb. per head daily. The corn was rolled prior to feeding in all experiments.
Aspen Material As A Feed Ingredient In Ruminant Rations, L. D. Kamstra, M. Singh, L. B. Embry, L. Peterson
Aspen Material As A Feed Ingredient In Ruminant Rations, L. D. Kamstra, M. Singh, L. B. Embry, L. Peterson
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1976
Aspen (Populus tremuloides), covering in excess of 58,000 acres in the Black Hills area and over 3 million acres in the Upper Great Lakes area, has not been harvested in sufficient amounts to perpetuate growth. Periodic harvesting is not only necessary to assure an aspen stand but younger trees are needed as a source of food for grouse, deer and other wildlife. Although aspen serves as a source of fiber for paper, lumber, insulation and other industrial uses, it is presently not used for these purposes in the Black Hills region. In all regions where aspen grows whether or not …

Crafty Carp Cookery, D. Deethardt
Crafty Carp Cookery, D. Deethardt
Research Bulletins of the South Dakota Agricultural Experiment Station (1887-2011)
A study has been made on the acceptability of carp meat from several eastern South Dakota lakes and the Oahe Reservoir on the Missouri River. It was evident from this study that carp from these sources were acceptable for human consumption (1.).
The nutritive value of fresh-water fish varies somewhat depending on the season of the year, geographical area of capture, size and sex of the fish, feeding habits and other factors. For this reason, only approximate nutrient values can he given for carp.

The duration of the test was 8 weeks starting with day-old Golden Giant broiler male chicks.
Copper And Nystatin For Growing Turkeys, E. Guenthner, C. W. Carlson
Copper And Nystatin For Growing Turkeys, E. Guenthner, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1976
Previous experiments at this station have shown that we can expect a growth response of approximately 500 grams at maturity when extra copper (120 ppm of the diet) is fed to growing turkeys. This response is usually manifested during the later part of the growing period. Liver tissue analyses indicate that this level of dietary copper does not increase the amount of tissue copper. Since the extra copper apparently is not absorbed by the animal, perhaps part of the beneficial response comes from the effect of copper on the feed itself, i.e., by preventing growth of undesirable organisms. However, concern …

Fatty Liver Hemorrhagic Syndrome In Laying Hens, R. A. Nelson, C. W. Carlson
Fatty Liver Hemorrhagic Syndrome In Laying Hens, R. A. Nelson, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1976
Fatty liver hemorrhagic syndrome (FLHS), a major cause of mortality among caged laying hens, was second (15%) to lymphoid leukosis in 1975 among those hens submitted to the Animal Disease Research and Diagnostic Laboratory from this research station. The disease is characterized by a 20 to 25% increase in body weight, a 25 to 30% decrease in egg production and an Increase in mortality from excessive liver fat and liver hematomas. Two more experiments on this subject have been completed. One used a normal feeding regime and the other used the force-feeding technique described in last year's Poultry Day Report …

Strain Effects With Low Protein Layer Diets, A. B. Kashani, C. W. Carlson
Strain Effects With Low Protein Layer Diets, A. B. Kashani, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1976
Previous studies at the South Dakota Experiment Station showed that average hen-day egg production over fifteen 28-day periods was reduced from 70 to 67% when the protein content of the diet was lowered from 16 to 12%. Furthermore, the combined addition of methionine and lysine depressed production to 61%. Tryptophan appeared to somewhat alleviate the depression effect caused by methionine and lysine, whereas isoleucine did not further improve hen performance.

The average number of flocks per year was 55, 62, 55, 49, and 30, respectively, for 1971 through 1975. This amounted to an average of 50 flocks per year, averaging 8,500 birds.
Low Protein Grower And Layer Diets And Their Effects On Reproductive Performance, R. A. Nelson, C. W. Carlson
Low Protein Grower And Layer Diets And Their Effects On Reproductive Performance, R. A. Nelson, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1976
Numerous studies, including several at this station, have shown that the layer type pullet can utilize diets as low as 10% protein during the later growing stages without affecting their subsequent reproductive performance. Frequently, these types of diets are rather bulky and therefore do not work properly in mechanical feeding systems. This year's study involved the use of 3 12% protein, 2825 Kcal diet that was supplemented with methionine and/or lysine to the NRG recommended levels. A fourth diet utilized dehulled oats as its major ingredient. Ten percent alfalfa and 2% yellow grease were used in each diet to help …
Feed Restriction Studies With Layers, E. Guenthner, C. W. Carlson
Feed Restriction Studies With Layers, E. Guenthner, C. W. Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1976
Limiting feed intake frequently is used to reduce the feed cost of producing eggs. Reducing the nutrient intake can be accomplished by limiting the daily feeding period, available feed or by including fiber to reduce the density of the diet. In a previous experiment in which feeders were covered at 3:00 p.m. and uncovered the following morning at 8:00 a.m., feed restriction adversely affected rate of egg production, feed conversion, egg size and the feed cost of producing eggs. The effects were more severe on the low energy low protein diets.
