Evaluation Of Implants, Clover, And Fescue Variety On Stocker Steers, Z. T. Buessing, J. K. Farney

Kansas Agricultural Experiment Station Research Reports

Sixty-four growing steers were used in a split-plot experiment, where the whole plot was pasture, and the split-plot was implants. Whole plot treatment was a 4 × 2 facto­rial with four levels of fescue (High Endophyte, Low Endophyte, Novel, or Endophyte Free) and two levels of legume (Legumes or No Legumes). The split-plot included four implant levels (No Implant, Synovex One Grass, Revalor-G, Ralgro). Data collected were weights, hair coat scores, hair length, rectal temperature (every 28 days), and ultrasound carcass characteristics coming off grass. Steers on High Endophyte had the lowest average daily gain (ADG), longest hair, and highest …

Bermudagrass Fertility Trial In Southeast Kansas, 2020, D. Helwig, M. Haywood, J. K. Farney, B. C. Pedreira, G. F. Sassenrath

Kansas Agricultural Experiment Station Research Reports

In 2020 a bermudagrass fertility study was conducted at the K-State Research and Ex­tension experiment station outside of Columbus, KS. The purpose of the study was to simulate forage producer practices of managing bermudagrass and determine how each practice affects forage production and quality. Addition of fertilizer, and mowing were tested to determine the impact on forage biomass production and quality. Fertilizer increased both biomass production and forage quality. However, greater improvements in forage quality were observed by mowing the bermudagrass.

Impact Of Fertility And Mowing On Crabgrass Quantity And Quality For Hay Production In Southeast Kansas, D. Helwig, M. Haywood, J. K. Farney, B. C. Pedreira, G. F. Sassenrath

Kansas Agricultural Experiment Station Research Reports

A crabgrass variety trial comparing Quick-N-Big and MoJo crabgrasses was conducted during the summer of 2020 at the K-State Research and Extension experiment station near Columbus, Kansas. The trial evaluated quantity and quality of forage produced under different nitrogen fertility scenarios and mowing management techniques. MoJo produced more biomass than Quick-N-Big. Addition of nitrogen fertilizer increased biomass production and forage protein content. Mowing was also found to enhance forage quality.

Effects Of Early Or Conventional Weaning On Beef Cow And Calf Performance In Pasture And Drylot Environments, G. W. Preedy, J. R. Jaeger, J. W. Waggoner, K C. Olson, K. R. Harmoney

Kansas Agricultural Experiment Station Research Reports

During widespread drought, pasture availability and productivity are reduced. This, coupled with increasing land prices and lease rates, has prompted the evaluation of al­ternative management strategies that decrease grazing pressure on perennial pasture or reduce feed and pasture costs. Weaning early and moving cows from pasture to a drylot environment is used commonly for reducing grazing pressure on perennial pastures. A premature end to lactation reduces cow nutrient requirements and reduces grazing pressure. Removal of the calf further reduces grazing pressure, as calves are significant consumers of forage dry matter (DM) during mid and late lactation. The combina­tion can be …

Effects Of Frequency Of Protein Supplementation On Performance By Beef Calves Grazing Dormant Native Range, G. W. Preedy, J. R. Jaeger, J. W. Waggoner, K C. Olson

Kansas Agricultural Experiment Station Research Reports

Stocker calves that graze forages before entering a feedlot account for more than 75% of the beef calves raised in the United States each year. A large proportion of those will be calves born in the spring and weaned in the fall. Modest growth rates are expected when the quality of fall and winter forages is poor. Growing calves in confinement systems during fall and winter typically allows for greater average daily gain (ADG) than graz­ing low-quality forages; however, modest overall costs associated with grazing perennial, dormant forages may be competitive during times when feed prices are relatively high.
