Última Optimal Grazing Termination Date for Dual-Purpose Winter Wheat Production AgEcon Taylor, Karen W.; Epplin, Francis M.; Brorsen, B. Wade; Fieser, Brian G.; Horn, Gerald W.. Dual-purpose winter wheat (fall-winter forage plus grain) production is an important economic enterprise in the southern Great Plains. Grazing termination to enable grain production is a critical decision. The objective is to determine the optimal grazing termination date for dual-purpose wheat. The value of knowing the occurrence of first hollow stem (FHS), a wheat growth threshold for grazing termination, is also determined. Results indicate that for most price situations grazing should be terminated at or before FHS. Marginal wheat returns from extended grazing were negative and the value of FHS information ranges from $1.50 to $10 per acre.

Ano: 2010 URL: http://purl.umn.edu/57148 DERIVATION AND OPTIMIZATION OF A STOCHASTIC LIVESTOCK WEIGHT GAIN RESPONSE TO STOCKING DENSITY MODEL AgEcon Kaitibie, Simeon; Epplin, Francis M.; Brorsen, B. Wade; Horn, Gerald W.; Krenzer, Eugene G., Jr.; Paisley, Steven I.. Dual-purpose winter wheat production is an important economic enterprise in the southern Great Plains of the United States. Because of the complex interactions involved in producing wheat grain and beef gain from a single crop, stocking density is an important decision. The objective of the research is to determine the stocking density that maximizes expected net returns from dual-purpose winter wheat production. Statistical tests rejected a conventional linear-response plateau function in favor of a linear-response stochastic plateau function. The optimal stocking density of 1.48 steers per hectare (0.60 steers per acre) is 19% greater with a stochastic plateau than with a nonstochastic one.

Ano: 2002 URL: http://purl.umn.edu/36538 ENERGY SUPPLEMENTATION STRATEGIES FOR WHEAT PASTURE STOCKER CATTLE UNDER UNCERTAIN FORAGE AVAILABILITY AgEcon Coulibaly, Nouhoun; Bernardo, Daniel J.; Horn, Gerald W.. Energy supplementation provides a means of reducing production risk of growing stocker cattle on winter wheat pasture. This study addresses the issue of risk aversion and energy supplement input use. Differences in supplementation practices induced by risk aversion and the effects of cattle and feed market conditions are examined. Results show that supplementation practices are likely to be similar across producers, irrespective of their risk attitudes. Cattle and feed market conditions, however, markedly affect supplementation practices. These findings provide information for assisting stockmen in identifying efficient supplement strategies.

Ano: 1996 URL: http://purl.umn.edu/15244 MANAGEMENT PRACTICES AND LEASE ARRANGEMENTS USED BY OKLAHOMA WHEAT, WHEAT PASTURE, AND WHEAT PASTURE LIVESTOCK PRODUCERS AgEcon Hossain, Ishrat; Epplin, Francis M.; Krenzer, Eugene G., Jr.; Horn, Gerald W.. Winter wheat is grown for three purposes in the Southern Plains, grain-only, forage-only, and as a dual-purpose forage plus grain crop. The USDA's wheat cropping practices survey does not differentiate among the three uses. Little information on actual production practices across use is available. Results of a survey are presented.
