Feeding and the Equilibrium Feeder Animal Price-Weight Schedule, June 2005

The feeder animal price is a derivative in the sense that its value depends upon the price of animals for the consumption market. It also depends upon the biological growth technology and feed costs. Daily maintenance costs are of particular interest to the husbander because they can be avoided through accelerated feeding. In this paper, the optimal feeding path under equilibrium feeder animal prices is established. This analysis is used to gain a better understanding of feeding decisions, regulation in feedstuff markets, and the consequences of genetic innovations. It is shown that days on feed can increase or decrease with a genetic innovation or other improvement in feed conversion efficiency. The structure of comparative prices for feeder animals at different weights, the early slaughter decision, and equilibrium in feeder animal markets are also developed. Feeder animal prices can increase over a weight interval if biological feed efficiency parameters are low over the interval.

05005-002 Farmers Creek Watershed Final Report

Farmers Creek is a moderately flowing stream that winds through seventeen miles of central Jackson County, encompassing a watershed area of 30,590 acres. Due to nutrient loading and sedimentation, the stream was placed on Iowa’s 303(d) List of Impaired Waters in 2002. A three year grant project was initiated in January 2005 to reduce both sediment delivery and phosphorus levels by 40% in critical areas along the stream corridor. Over thirty-five BMP’s were started in the first nine months of this project. Funding through WIRB is being requested specifically for streambank stabilization and protection projects not covered by other cost-share programs. Innovative project designs and techniques will be installed and act as demonstration sites. Projects may include jetties, weirs, cedar revetments, cattle crossings, and fencing. To assist in excluding cattle from the stream, watering systems such as slingpumps, pasture pumps, or water rams will be installed, in conjunction with filter strips and riparian buffers.
