Methods of Vitamin A Supplementation for Fattening Beef Cattle

The objective of this experiment was to study the effects of administering vitamin A through a mineral supplement or injection on feedlot performance and liver storage of vitamin A. The feeding trail was conducted at James Valley Agricultural Research and Extension Center near Redfield during the summer and fall of 1977. The present study also involved a comparison of conventionally-dried, solar-dried and acid-treated corn. Feedlot performance results for these treatments have been reported in the 1978 Progress Report of the Center

Response of Feedlot Lambs to Chlortetracycline and Sulfamethazine

The objective of this experiment was to test the effects of chlortetracycline and sulfamethazine alone and in combination on feedlot performance and incidence of diseases of lambs weaned at an early age, shipped and finished in drylot with a high-concentrate ration

Oat Grain Rations for Growing and Finishing Cattle

The poor animal performance obtain with rations containing a high amount of oats indicated a need to more accurately describe the place of oats in growing and finishing rations for cattle. Therefore, this experiment was conducted to study whole, rolled or ground and pelleted oats as the only grain for feedlot steers. Feedlot performance and digestibility were determined and compared for each form of oats

Performance of Lambs Fed Rations With Oyster Shells or Various Levels of Hay

High-concentrate rations have been shown to have several advantages in large cattle feeding operations because they produce high rates of gain with low feed requirements. It has been a common practice to feed lamb rations with relatively high levels of roughage. However, lamb feeders might also benefit under many conditions if results similar to those with cattle fed high-concentrate rations could be obtained with lambs. Little research has been reported on the relative value for lambs of all-concentrate rations and those with low levels of roughage or roughage replacers such as oyster shells. Two experiments were conducted to study feedlot performance of lambs fed rations which contained oyster shells or various levels of hay

Ear Corn and Shelled Corn Diets for Finishing Cattle

Comparisons were made between ear corn and shelled corn in various types of diets for finishing cattle. These data should be considered most appropriate for heavy yearling cattle fed over a period of about 4 months

Lasalocid or Monensin Supplementation for Short Periods of Finishing

Information is needed on response to lasalocid and monensin under conditions of rapid adaptation to high-concentrate diets and short periods of finishing for heavyweight cattle. Two experiments were conducted to obtain data when feeding under these conditions

Lasalocid Supplementation for Grazing Steers

Management systems for pastures and for the grazing animals can be major factors in the amount and efficiency of production. Several nutritive and nonnutritive products have been reported to improve utilization of pasture forages and animal performance. Improvement in rate and efficiency of production can be of considerable economic benefit. The importance becomes greater with increasing costs and livestock production. Lasalocid sodium (Bovatec) is a feed additive shown to improve growth rate and feed efficiency of cattle in the feedlot and on pasture. Two experiments were conducted to test the product when fed at 100, 200 or 300 mg per head daily in a corn supplement to steers grazing predominately bromegrass pasture

Whole or Rolled Oats for Finishing Cattle

Whole and rolled oats were compared in finishing ratiosn for steets. On basis of feedlot performance calculated from carcass weight and 60% yield, steers fed rolled oats gained faster (10.5%) and more efficiently (11.6%) than those fed whole oats. Carcass characteristics measured favored steers fed rolled oats and having slightly heavier carcasses. The oat rations did not compare favorably with normally expected performance from high-concentrate rations with corn as the major grain. Other research is needed to properly evaluate oats as a major feed grain in cattle finishing rations

Implanting Site for Ralgro Compared to Synovex-S for Growing and Finishing Steers

Previous experiments (CATTLE 81-2) compared Ralgro implanted at the conventional shallow site, about mid-ear between skin and cartilage of the ear, and at an alternate deep site near the base of the ear to Synovex-S for finishing steers. In two experiments, the average improvements in weight gain for Ralgro at the shallow site, the deep site and Synovex-S were 8.3, 11.1 and 12.0%, respectively, over non-implanted controls. Feed efficiency was improved 7.1, 4.8 and 5.6%, respectively, over controls for these implant treatments. Additional data were considered desirable to include a growing phase as well as a finishing phase using the same implant treatments as in the previous experiments

Conventionally-Dried, Solar-Dried and Acid-Treated Corn for Finishing Beef Cattle

An experiment was initiated at the James Valley Research and Extension Center, Redfield, during the summer of 1976 to determine the value of corn grain dried or preserved by different methods. A portion of the trial dealt with methods of administering vitamin A and these results will be reported at a later time
