Economic Effects Of Horn Fly (Diptera: Muscidae) Populations On Beef Cattle Exposed To Three Pesticide Treatment Regimes, Jerome Hogsette, David Prichard, Joseph Ruff

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Horn flies could not be maintained below 50 per animal with sprays or dusts during a 21-wk study. However, weights of cows and calves and condition scores of cows were not influenced by suppression of Haematobia irritans (L.) populations. Results show that cattle in northwest Florida can tolerate average populations of >200 flies for 70 d with no adverse economic effects. Spray treatments providing the best fly control were Lintox-D and Ra-Vap. The most economical products for use were Del-Tox, Lintox-D, and Ra-Vap.

Use Of A Simulation Model To Evaluate The Influence Of Reproductive Performance And Management Decisions On Net Income In Beef Production, L. A. Werth, S. M. Azzam, Merlyn K. Nielsen, J. E. Kinder

Department of Animal Science: Faculty Publications

A stochastic dynamic model of reproduction and a deterministic cow-herd economic simulation model were used to evaluate how management decisions and reproductive performance interact to influence net income in a cow-calf operation (1,000 cows) for 1 yr of production. The stochastic model was used to determine herd performance when length of breeding season (45, 70, or 120 d) interacted with three postpartum intervals of an estrus (48, 65, or 90 d) and three conception rates at first service (60, 70, or 80%). Short, moderate, and long postpartum intervals were used to reflect differences in reproductive performance. In addition, replacement heifers …

G91-1053 Looking For Buy And Sell Signals From Charts, Lynn H. Lutgen

University of Nebraska-Lincoln Extension: Historical Materials

The third in a series of nine on the basics of technical analysis, this NebGuide explains what to look for in commodity charts.

Producers always look for the ultimate: ever-accurate, foolproof, technical signals to tell what moves to make in the market. The problem is the markets are an ever-changing phenomenon; no one signal can predict prices with 100 percent accuracy.

This NebGuide is design to give readers a feel for different kinds of tecnical signals analysts look for to determine market direction. Major signals discussed are: key reversals, double and triple bottoms, head and shoulders (top and bottom), and …
