Zeranol Implants for Feedlot Lambs

The objectives of two experiments reported here were to determine the value of reimplanting feedlot lambs with zeranol 40 or more days prior to slaughter

Dry or High-Moisture Corn with Hay or Haylage at Various Levels for Feedlot Lambs

Several experiments at this station with feedlot cattle have shown that high-moisture corn grain has frequently resulted in improved weight gain and feed efficiency over dry corn. There have been indications that the level of roughage and the moisture content of the roughage may have an influence on the comparative value of dry and high-moisture corn. This experiment was designed to study the value of dry or high-moisture corn in all-concentrate rations and with various levels of alfalfa-brome hay or haylage for growing and finishing lambs

Diethylstilbestrol, Zeranol or Synovex-S Implants for Growing Steers

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

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

Effects of Monensin on Feedlot Performance of Growing and Finishing Steers

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

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

Response by Native Feedlot Lambs to Injectable Tramisol

The objective of this experiment was to further test Tramisol with feedlot lambs. Observations ere made as to the apparent initial reaction of the lambs to the injection evidence of swelling at site of injection and evidence of tissue damage at time of slaughter

Diethylstilbestrol, Zeranol or Synovex-S Implants for Finishing Steers

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

Energy Level in Ration, Market Weight and Types of Cattle

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

How Energy Level in Ration, Market Weight and Type of Cattle Influence Beef Carcass Traits

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
