Acid-Treated Vs. Dried Corn With And Without Zeranol Implants For Finishing Cattle, L. B. Embry, R. C. Ward
Acid-Treated Vs. Dried Corn With And Without Zeranol Implants For Finishing Cattle, L. B. Embry, R. C. Ward
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975
Corn grain is frequently harvested at a moisture content too high for safe keeping under conventional grain storage conditions. While this may be a desirable or necessary practice, the grain must be dried, stored under oxygen-limiting conditions, stored to produce ensiled grain or treated with an effective preservative to prevent spoilage during storage. Each of these methods is being used for preservation and storage of corn when harvested at a high-moisture content (20 to 30%) and used for feeding livestock. Total costs including storage structures, losses in processing and storage and comparative feeding value are factors involved in choice of …
Diethylstilbestrol, Zeranol Or Synovex-S Implants For Finishing Steers, L. B. Embry, W. S. Swan
Diethylstilbestrol, Zeranol Or Synovex-S Implants For Finishing Steers, L. B. Embry, W. S. Swan
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975
Direct comparisons between DES, zeranol and Synovex implants and a non-implanted control under various conditions and are more limited. In the experiment reported here, implants of the three products were compared to a nonimplanted control when steers were fed finishing rations with and without roughage.
Injectable Famphur For Control Of Grubs In Cattle, P. H. Kohler, R. N. Gates, L. B. Embry, L. B. Embry
Injectable Famphur For Control Of Grubs In Cattle, P. H. Kohler, R. N. Gates, L. B. Embry, L. B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975
Grubs are a major pest of cattle and cause considerable economic loss to the cattle industry. Running of cattle and standing in available water sources during heel fly strikes no doubt are reflected in lighter weaning weights of claves because of reduced grazing time and cows becoming separated from their calves. Other losses to producers and feeders include possible reduced feedlot performance by grub infested animals, weight loss and down grading of carcasses that are trimmed to remove areas damaged by grubs and a lower value for hides due to grub holes. Several effective products and methods of treatment are …
Energy Level In Ration, Market Weight And Types Of Cattle, L. B. Embry, W. J. Costello, W. S. Swan
Energy Level In Ration, Market Weight And Types Of Cattle, L. B. Embry, W. J. Costello, W. S. Swan
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975
The effect of body size on feed efficiency has been the subject of research for several years. Evidence was presented from some of the early research that body weight is unrelated to feed efficiency. Recent research has also shown that current recommended net energy requirements, such as those by the National Research Council, for growing and finishing beef cattle are valid for various sizes and types of beef animals. Large-bodied cattle gaining at a faster rate require more feed and should be fed ro heavier weights to reach best market grade.
Soybean Meal Or Urea During Feedlot Adaptation And Growing Of Calves, R. N. Gates, L. B. Embry
Soybean Meal Or Urea During Feedlot Adaptation And Growing Of Calves, R. N. Gates, L. B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975
This experiment investigated the response by calves to different levels of protein during the first four weeks of feedlot adaptation using soybean meal, urea or a combination of the two sources. Following the adaptation period, the calves were continued on experiment for a growing phase to compare soybean meal and urea as supplements to corn silage.
Feedlot Health Through Preventative Management, M. W. Vorhies
Feedlot Health Through Preventative Management, M. W. Vorhies
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975
Livestock production has become increasingly intensive and the momentum of the change has been so great that realistically it has been instrumental in presenting the Veterinarian with problems that have outstripped his knowledge.
Factors Affecting The Cattle Industry Outlook Situation, Gene E. Murra
Factors Affecting The Cattle Industry Outlook Situation, Gene E. Murra
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975
Historically, many of the demand and supply relationships which impact on the cattle industry in the United States and South Dakota have been rather easy to analyze. This is not true today--many of the old, simple relationships have become complex. The purpose of this paper will be to present some of the demand and supply relationships as they pertain to outlook.
How Energy Level In Ration, Market Weight And Type Of Cattle Influence Beef Carcass Traits, W. J. Costello, L. B. Embry, W. S. Swan
How Energy Level In Ration, Market Weight And Type Of Cattle Influence Beef Carcass Traits, W. J. Costello, L. B. Embry, W. S. Swan
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975
An experiment reported in this publication under the title "Energy Level in Ration, Market Weight and Types of Cattle" provided material to observe the influence of the three factors listed on beef carcass characteristics. Details describing the cattle, rations and market weights are presented in that report.
Marketing Margins For Beef And Related Considerations, Bruce A. Ginn
Marketing Margins For Beef And Related Considerations, Bruce A. Ginn
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975
In an environment where inflation has become a way of life, rising prices are a natural accomplice. High prices are fine--for the seller. But those of us who wear the hat of the consumer (and that's all of us) greet escalating costs with a less than joyful attitude. The question is, Can consumers, longshoremen, producers, shippers, and the Russians find happiness together? In some respects the interests of the producer and the consumer may not be significantly different and could form the basis of an alliance in which marketing innovations could take place.

Induction Of Parturition In The Ovine, Ernest L. Harman
Induction Of Parturition In The Ovine, Ernest L. Harman
Electronic Theses and Dissertations
The effects of flumethasone and prostaglandin F2 (PGF) on the time of parturition were studied in the ewe. Pregnant ewes with known conception dates were allotted into a 3 x 3 x 2 factorial designed experiment (1973 study) and into a completely random designed experiment (1974 study). In the 1973 study treatments consisted of three hormones (flumethasone, PGF and saline control), three levels (low, .5 mg flumethasone, 5 mg PGF, 1 cc saline; medium, 1.0 mg flumethasone, 10 mg PGF, 2 cc saline; high, 1.5 mg flumethasone, 15 mg PGF, 3 cc saline) and two routes of administration (IM …
Factors Affecting The Development Of Lipase Flavor In Butter, Lawrence I. Bell
Factors Affecting The Development Of Lipase Flavor In Butter, Lawrence I. Bell
Electronic Theses and Dissertations
Current trends in the dairy industry have resulted in an increase in the incidence of lipase flavored butter. Raw cream, fresh and aged 24 h, was divided into 3 fractions and heat treated at temperatures of 72 C, 85 C, and 93 C. Each fraction of cream was churned into butter, with the butter divided and stored at -28. 9 C and 4.4 C. Lipase flavor development was measured organoleptically, by acid degree value (ADV), and free fatty acids (FFA) using a colorimetric procedure. Age of the cream had a significant effect (P< .01) on FFA and. ADV .levels, whereas heat treatment .of the cream had a significant effect (P< .01) on flavor only. Storage time had a significant effect (P< .01) on FFA, ADV, and flavor and the temperature of storage had a significant effect (P< .01) on FFA ·and flavor. Correlation between FFA and ADV was 0.86. There was no correlation between flavor and either JTFA or ADV
Amino Acid Additions To A Low Protein Corn-Soy Diet For Egg Production, Ali Baghaye Kashani
Amino Acid Additions To A Low Protein Corn-Soy Diet For Egg Production, Ali Baghaye Kashani
Electronic Theses and Dissertations
The present study was conducted to determine if the protein level of layer diets could be lowered from the: commonly used 16 percent to 12 percent by supplementation of some of the essential amino acids without reducing the performance of hens. The amino acids used were methionine, lysine, tryptophan and isoleucine. Egg production, egg shell thickness, interior egg quality, body weight, feed efficiency and free amino acid content of the albumen of eggs produced were criteria used to measure the (--) to treatment.
