An Efficient Stocking Strategy For Grazing Replacement Heifers, Keith R. Harmoney, John R. Jaeger Jan 2020

An Efficient Stocking Strategy For Grazing Replacement Heifers, Keith R. Harmoney, John R. Jaeger

Kansas Agricultural Experiment Station Research Reports

Even though Kansas native rangelands often have steep slopes or shallow soils not con­ducive to many other uses other than livestock grazing, native rangeland and perennial grassland acres in Kansas have been declining. Cropland acreage over this same time frame has increased, and rangelands have also become more fragmented by small ranch­ettes and urbanization. Producers may be looking to increase production efficiency on a shrinking forage land base. The use of intensive early stocking (IES) is one of the most efficient stocking strategies to produce beef on rangeland acres. The IES strategy has been widely used in eastern ...


Using Modified Intensive Early Stocking For Cow/Calf Production, Keith R. Harmoney, John R. Jaeger Jan 2020

Using Modified Intensive Early Stocking For Cow/Calf Production, Keith R. Harmoney, John R. Jaeger

Kansas Agricultural Experiment Station Research Reports

Intensive early stocking (IES) was introduced nearly a half century ago in eastern Kan­sas and has since been adopted as a major management tool to increase animal produc­tion, efficiency of production, and economic return on tallgrass rangelands. These in­creases have come almost exclusively by using IES with young stocker animals. Intensive early stocking and its gains have been proven effective repeatedly in published research. A similar modified IES (MIES) system has increased production efficiency of stocker animals on western Kansas rangelands. Perennial grassland acres for cattle produc­tion, as well as cattle numbers, are declining. Using management ...

Effect Of Exercise On Health And Performance By Long-Haul, High-Stress Steers During The Receiving Period, John R. Jaeger, Justin W. Waggoner, Keith R. Harmoney, Quentin Rupp

Kansas Agricultural Experiment Station Research Reports

Morbidity and mortality associated with the bovine respiratory disease (BRD) complex continue to be a significant challenge to the United States beef industry. Stress associ­ated with maternal separation, environment change, transportation, diet changes, and commingling are common to beef industry marketing channels and have been linked to depressed growth and health of recently weaned calves. Cattle originating from the Southeastern U.S. tend to exhibit high rates of BRD after transportation to Great Plains feedlots.

Previous research has utilized exercise one time per day or three times per week for the receiving period. In those studies, health performance of ...

Kansas Agricultural Experiment Station Research Reports

A total of 280 nursery pigs (DNA 241 × 600, initially 22.8 lb) were used in a 21-d growth trial to determine the available P (aP) release curve for Smizyme TS G5 2,500 (Origination, LLC., Maplewood, MN). Pigs were weaned at approximately 21 d of age, randomly allotted to pens based on initial body weight (BW), and fed common starter diets. On d 21 post-weaning, considered d 0 of the study, pens were blocked by BW and randomly allotted to 1 of 7 dietary treatments with 5 pigs per pen and 8 pens per treatment. Seven 1-ton batches of ...
