Analysis Of Kansas Hog Enterprise Returns From 1981-1990 (1990), Michael R. Langemeier Jan 1990

Analysis Of Kansas Hog Enterprise Returns From 1981-1990 (1990), Michael R. Langemeier

Kansas Agricultural Experiment Station Research Reports

Estimated historical return distributions for farrow-to-finish, feeder pig finishing, and feeder pig producing operations in Kansas from 1981-1990 were examined. Average returns per head were the highest and downside risk was the lowest for farrow-to-finish operations over this period. However, the required investment in buildings, equipment, and breeding stock per head was also higher for this operation. Thus, a tradeoff exists between returns per head and capital requirements per head.; Swine Day, Manhattan, KS, November 15, 1990

Price Discovery And Basis Risk For Live Hogs (1990), Ted C. Schroeder, B K. Goodwin

Kansas Agricultural Experiment Station Research Reports

The short- and long-run daily price relationships between cash and futures markets for live hogs were examined over the 1975-89 period. Price discovery generally originates in the futures market with about 65% of new information being passed from the futures to the cash market. However, at times, especially during large price moves that are not necessarily anticipated in the futures market, the cash market price relies less on the futures market. The very short-term basis for hogs is fairly stable, with approximately 85% of yesterday's nearby-basis persisting today. Generally, little can be gained by speculating on basis from day to …

Improving On-Farm Mixing Efficiency (1990), Robert D. Goodband Jan 1990

Improving On-Farm Mixing Efficiency (1990), Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

Particle size reduction has a great impact on efficiency of feed utilization. Decreasing particle size improves digestibility of nutrients by increasing surface area and allowing for greater interaction with digestive enzymes. In addition, particle size reduction can influence how uniformly feed is mixed and potential for segregation of ingredients. Mixing equipment and times also need to be evaluated to ensure feed uniformity. Very often suggested mixing times underestimate the amount of time necessary to thoroughly mix feed. Items such as worn paddles or ribbons, ribbon or paddle speed, and overfilling mixers increase the time necessary for adequate feed mixing and …
