Dye Marking Of Antibiotics Used In Treatment Of Mastitis In Dry And Lactating Cows, Richard A. Ellefson Jan 1982

Dye Marking Of Antibiotics Used In Treatment Of Mastitis In Dry And Lactating Cows, Richard A. Ellefson

Electronic Theses and Dissertations

Mastitis is the one major disease affecting dairy cows; considerable direct and indirect economic losses can be attributed to mastitis (6). Treatment of mastitis with antibiotic preparations will alleviate most disease symptoms. Problems may arise when cows treated with antibiotics have their milk used for commercial milk processes before antibiotics are clear. They are: 1) some people are allergic to penicillin, and 2) cultured dairy products may not grow because of inhibition. The Food, Drug, and Cosmetic Act established that milk and milk products containing antibiotics are considered adulterated. Due to recent innovations in antibiotics testing The National Conference on …

Whey-Caseinate Blends And Lactose Hydrolysis In Yogurt Manufacture, Catherine A. Whalen

Electronic Theses and Dissertations

Yogurt is a highly nutritious cultured dairy product which has been consumed for centuries, particularly in Eastern Europe. Although per capita consumption in the United. States is still far below that of most European countries; yogurt sales in the U.S.A. have increased phenomenally during the past three decades. Yogurt sales in the U.S.A. totaled 7.7 million kg in 1955; 31.8 million kg in 1966; and approximately 227 million kg by 1976 (41). Per capita sales increased 211% from 1970 to 1980 (45). Yogurt is generally manufactured from milk or lowfat milk which has been fortified with extra milk solids. Nonfat …

Use Of Dry Whey And Lactose Hydrolysis In Yogurt Bases, Nagendra P. Shah Jan 1982

Use Of Dry Whey And Lactose Hydrolysis In Yogurt Bases, Nagendra P. Shah

Electronic Theses and Dissertations

Yogurt is one of the oldest and most traditional fermented dairy products. Since early times it has been an important food item of the people in the Middle East. Except for its refreshing taste and wholesomeness as a food, no special virtues were claimed for it until early in the 20th century when the bacteriologist, Elie Metchnikoff, who shared a Nobel Prize in 1908, concluded from his studies on the effect of lactic acid bacteria of the digestive tract, that yogurt arrests putrefaction in the intestinal tract and thus might be beneficial to health (55). Attempts to popularize yogurt in …

Savory Grazing System: A Research Update, L. S. Bilger, J. K. Lewis, D. M. Engle, T. Weber Jan 1982

Savory Grazing System: A Research Update, L. S. Bilger, J. K. Lewis, D. M. Engle, T. Weber

South Dakota Cow-Calf Field Day Proceedings, 1982

Livestock performance, forage use and soil compaction were studied in Repeated Seasonal (RSG) and High Performance Short Duration Grazing (HPSDG) systems on mixed prairie in good to excellent condition in western South Dakota. In May 1981 and 1982, yearling ewes were allocated to six RSG and six HPSDG pastures and removed in October of each year. Stocking rates in both systems were periodically adjusted to result in 40 to 50% terminal use of shortgrasses. In both years, the stocking rates in HPSDG were approximately twice those in RSG. Livestock performance was the same in both systems. Forage use was more …

Evaluation Of Pasture Systems And Grain Levels For Growing Beef Cattle With Prediction Equations For Estimating Animal Performance, Steven C. Fransen Jan 1982

Evaluation Of Pasture Systems And Grain Levels For Growing Beef Cattle With Prediction Equations For Estimating Animal Performance, Steven C. Fransen

Electronic Theses and Dissertations

A three-year grazing study evaluated native, native-interseeded range and a tame grass pasture production, quality and animal performance. Animal production and performance were evaluated with yearling steers fed corn daily at zero, 0.5 and 1.0 percent of body weight. Interseeding alfalfa into native rangelands enhanced sod-forming over bunch grasses and allowed alfalfa to become the dominant species. Alfalfa was not selectively graved in the interseeded range and in 1978 contributed 35 percent of the dry matter yield during the spring and summer. Forage quality declined with maturity; IVDMD and CP decreased while ADF, NDF, lignin and silica all increased with …

Interactions Of Pen Space And Antibiotics As They Affect Performance Of Weanling Pigs, G. W. Libal, S. Josphson, R. C. Wahlstrom Nov 1981

Interactions Of Pen Space And Antibiotics As They Affect Performance Of Weanling Pigs, G. W. Libal, S. Josphson, R. C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1981

Crowding more pigs into a nursing pen than is recommended is a fairly common practice among producers who have limited facilities or high overhead costs. The effect of this crowding on performance has not been determined. The value of antibiotics in the nursing pig's diet has been well documented. This study was designed to evaluate the effect of pen space. and antibiotics and the possible interaction of the two as related to pig performance.

Effect Of Pen Space On Performance Of Growing-Finishing Pigs, G. W. Libal, R. C. Wahlstrom Nov 1981

Effect Of Pen Space On Performance Of Growing-Finishing Pigs, G. W. Libal, R. C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1981

For a number of years, the recommended space allowance for pigs has been 4 square feet and 8 square feet for the growing and finishing periods, respectively. Some producers have provided less pen space in an attempt to spread high facility costs over more pigs and thus lower per pig overhead costs. Some animal welfare spokesmen have expressed the opinion that even the recommended pen space allotments are too restrictive for both the pigs' performance and welfare.
The study reported herein was designed to evaluate performance of pigs housed in groups of 12, 16 or 20 pigs per pen and …

Simple And Complex Diets For Early Weaned Pigs, R. C. Wahlstrom, G. W. Libal, D. L. Hagemeier Nov 1981

Simple And Complex Diets For Early Weaned Pigs, R. C. Wahlstrom, G. W. Libal, D. L. Hagemeier

South Dakota Swine Field Day Proceedings and Research Reports, 1981

During recent years many swine producers have adopted the practice of weaning pigs between 21 and 28 days of age. This allows for a shorter interval between farrowings, resulting in more litters per sow per year. Most research has indicated early weaned pigs perform better when fed complex diets containing some milk product, sugar, fat, oats or other ingredients compared to simple corn-soybean meal fortified diets. However, the economics of cost of feed per unit of gain has often favored the simple diets.
The objective of this experiment was to evaluate pig starter diets equalized in lysine content but varying …

Effect Of Sorting Pigs Into Uniform Weight Groups At Birth, G. W. Libal, R. C. Wahlstrom Nov 1981

Effect Of Sorting Pigs Into Uniform Weight Groups At Birth, G. W. Libal, R. C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1981

It has been demonstrated that larger pigs at birth have a greater survival rate than do small pigs, particularly in large litters. It is assumed that part of the death loss is because smaller pigs are weaker and do not compete well in establishing the peck order for position of nursing. It would seem logical that lessening the competition due to size differences at birth would lead to less death loss before weaning. The experiment reported herein was designed to evaluate the effect on pig performance and survivability of sorting pigs into groups of similar weight.

Crossbred Boars Can Be Used To Improve Reproductive Efficiency, Rodger K. Johnson Nov 1981

Crossbred Boars Can Be Used To Improve Reproductive Efficiency, Rodger K. Johnson

South Dakota Swine Field Day Proceedings and Research Reports, 1981

Lack of sexual aggressiveness and infertility in boars are problems that have been experienced to some degree by nearly every swine producer. The impact of these problems on the efficiency of swine production depends on their frequency; but even relatively few boar reproductive problems can upset the production schedule of units that are farrowing continuously.
Recent research provides convincing evidence that at 7 to 9 months of age crossbred boars are more aggressive breeders than purebreds and that conception rates are higher for females mated to crossbred boars. The purpose of this report is to examine the research that compares …

Effect Of A Lactobacillus Culture In Diets Of Growing-Finishing Swine, R. C. Wahlstrom, G. W. Libal Nov 1981

Effect Of A Lactobacillus Culture In Diets Of Growing-Finishing Swine, R. C. Wahlstrom, G. W. Libal

South Dakota Swine Field Day Proceedings and Research Reports, 1981

Lactobacillus cultures have been used in the preservation of human foods for centuries. More recently it has been shown that feeding lactobacillus to pigs can influence the bacterial flora of the intestinal tract. A reduction in enteritis and also an improvement in weight gain have been reported, although the results with lactobacillus cultures as feed supplements have been variable.
The objective of this study was to evaluate a dried viable culture mixture of lactobacillus in diets of different protein content for growing-finishing swine.

Effect Of Pen Space And Vitamin Level On Performance Of Growing-Finishing Swine, R. C. Wahlstrom, G. W. Libal Nov 1981

Effect Of Pen Space And Vitamin Level On Performance Of Growing-Finishing Swine, R. C. Wahlstrom, G. W. Libal

South Dakota Swine Field Day Proceedings and Research Reports, 1981

Previous research at South Dakota State University has shown that pigs housed in a completely enclosed confinement building consume less feed and gain slower during enclosed confinement building consume less feed and gain slower during the finishing period than pigs housed in an open-front facility. Boredom or building fatigue caused by prolonged confinement in a limited space have been suggested as possible causes of this reduced performance.
The experiment reported herein was conducted to obtain information on the effect of increasing pen space and/or doubling the level of vitamins in the diet during the finishing from approximately 140 pounds to …

Effect Of Movement And Mixing Of Pigs On Performance During The Finishing Period, R. C. Wahlstrom, G. W. Libal Nov 1981

Effect Of Movement And Mixing Of Pigs On Performance During The Finishing Period, R. C. Wahlstrom, G. W. Libal

South Dakota Swine Field Day Proceedings and Research Reports, 1981

During the past few years producers have reported that growth rates of pigs plateau or even decline during the finishing period rather than increasing to weights of 200 or 220 pounds as might be expected. The problem, sometimes referred to as "stall out", is often related to enclosed housing but not limited exclusively to this method of housing.
This experiment was one of a series that this station has conducted to study this problem. The objectives were to determine the effects of movement of pigs and also mixing and moving pigs at weights of about 140 pounds on performance to …

Digestibility Of Sunflower Seeds In Swine Diets, M. Kepler, G. W. Libal, R. C. Wahlstrom Nov 1981

Digestibility Of Sunflower Seeds In Swine Diets, M. Kepler, G. W. Libal, R. C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1981

Limited research has been performed using sunflower seeds as an ingredient in swine diets. Because of the large amount of sunflowers produced in South Dakota, it would be beneficial to determine their usefulness as a feed ingredient in livestock rations. Work conducted at North Dakota has shown levels of over 10% sunflower seeds in diets of growing- finishing pigs produced oily carcasses. Previous research at this station (SWINE 80-8) has shown the maximum level of ground, whole sunflower seeds to be fed to sows during late gestation and early lactation is between 25 and 50%.
In order to utilize sunflower …

Influence Of Supplemental Dietary Potassium On Performance Of Growing-Finishing Swine, R. C. Wahlstrom, G. W. Libal Nov 1981

Influence Of Supplemental Dietary Potassium On Performance Of Growing-Finishing Swine, R. C. Wahlstrom, G. W. Libal

South Dakota Swine Field Day Proceedings and Research Reports, 1981

Potassium is one of the mineral nutrients that has been considered to be present in adequate amounts in swine diets formulated with commonly used feed ingredients. However, nutrient contents of feed ingredients have been shown to change with intensive cropping practices and also with different feed processing procedures. Recent research has indicated that potassium may improve the utilization of lysine, particularly in diets containing lysine below recommended levels.
This study was conducted to evaluate the performance of growing-finishing pigs fed different levels of supplemental dietary potassium and to evaluate the effect of previous dietary lysine treatment on subsequent performance.

Wheat Bran In Grower Diets And Subsequent Performance Of Layers, A. B. Kashani, C. W. Carlson Nov 1981

Wheat Bran In Grower Diets And Subsequent Performance Of Layers, A. B. Kashani, C. W. Carlson

South Dakota Poultry Field Day Proceedings and Research Reports, 1981

Rearing diets relatively high in fiber content have been shown to improve subsequent performance of laying hens. Whether this was primarily due to the lower energy content of a 12% protein mostly oats diet or the presence of higher fiber could not be clearly established. The objective of this study was to investigate the effect of 17% wheat bran in an isocaloric and isonitrogenous diet as compared to a corn-soy control diet.

Sunflower Meal And Meat And Bone Meal As Protein Sources In Laying Hen Rations, S. M. Oruseibio, C. W. Carlson

South Dakota Poultry Field Day Proceedings and Research Reports, 1981

Sunflowers are the second most popular vegetable source of protein grown worldwide according to an FAO report (soybean is first). Many countries like Canada have used sunflower meal as a source of protein for laying hens. Egg production performance of hens on diets containing sunflower meal compared favorably to that of hens on soybean meal containing rations.

Fabrication Of Steaks From Spent Hens, W. J. Costello, J. D. Michels, S. C. Seideman, P. R. Durland Nov 1981

Fabrication Of Steaks From Spent Hens, W. J. Costello, J. D. Michels, S. C. Seideman, P. R. Durland

South Dakota Poultry Field Day Proceedings and Research Reports, 1981

Research at SDSU has demonstrated that meat from spent laying hens (spent fowl) can be utilized in the production of fabricated steaks and/or roasts. Previous studies utilized raw meat from carcasses that were manually deboned. Under commercial deboning, meat that has been precooked is more easily separated from the bone. Precooking reduces the ability for meat to hold together or bind in a processed product. Precooked and raw spent fowl muscles were compared as raw material for the production of fabricated steaks. The objective of this research was to produce from precooked spent fowl muscle a palatable restructured product that …

Effect Of Copper On The Sulfur Amino Acid Requirements Of Turkeys, A. Samie, A. B. Kashani, C. W. Carlson Nov 1981

Effect Of Copper On The Sulfur Amino Acid Requirements Of Turkeys, A. Samie, A. B. Kashani, C. W. Carlson

South Dakota Poultry Field Day Proceedings and Research Reports, 1981

Copper as copper sulfate is often used as a growth promoter and crop mold growth preventative in turkey diets. Addition of 120 ppm copper to turkey diets in a previous study caused a slight decrease in body weights at 8 and 16 weeks of age when the diets contained 75, 85 or 100% of the NRG (1977) recommended sulfur-containing amino acid levels. This level of copper was suspected to decrease sulfur amino acid (S-AA) utilization and cause growth depression. Thus, a factorial experiment was designed to determine the effect of three different levels of copper (60, 120 or 240 ppm) …
