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.
Protein Supplementation For Finishing Cattle Fed All-Concentrate Or Low Roughage (Alfalfa) Diets, L. B. Embry, W. S. Swan
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.
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.
Effects Of Monensin On Feedlot Performance Of Growing And Finishing Steers, L. B. Embry, W. S. Swan
Effects Of Monensin On Feedlot Performance Of Growing And Finishing Steers, L. B. Embry, W. S. Swan
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1974
Feed additives have become an important part of rations for feedlot cattle during the past several years. They have been shown to being about improved performance in various ways such as stimulating growth, favorable alterations in fermentative and synthetic activity of the digestive tract and improvement in general health of the animals allowing more efficienct absorption and utilization of nutrients consumed.

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.
Quality Measurement Of Hay Stored By Large Hay Packaging Systems, L. D. Kamstra, R. Schrempp, P. Turnquist, C. Johnson
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.
