Valuing Immature Grain Crops as Forage

Late planted corn, soybeans and oats crops can be harvested as forages instead of for grain. Options include corn or oat silage, earlage, and oat or soybean hay. Estimating a value for these crops is made difficult by the fact there are few reported prices or significant markets in which they are bought and sold. However, there are two other general approaches to valuing grain crops harvested as forage. Both are based on comparisons to alternative actions by either the forage buyer or seller

Educational Shortages in the Bookkeeping Courses of Study in the Indianapolis Public High Schools in 1942

The major purpose of this investigation is to make a limited but definite contribution to the task of revising the course of study in bookkeeping for the Indianapolis high schools

Freedom: A Symposium

Note: The idea of freedom has been a vital motivation for speculation, deliberation, and action throughout all time. In Its wake lie both assurance and confusion. Its backward glance falls upon olive branches some still wet with blood, for freedom ranges from divine heights\u27 to satanic depths in man\u27s definition and application. What and how we think of freedom is important to these times, the beginnings of our future. The four essays in this collection are attempts to reach a definition of freedom. We hope they may lead to individual considerations of this problem. -Edito

Adaptations to Host Infection and Larval Parasitism in Unionoida

Freshwater mussel larval parasitism of fish is unique among bivalves. The relationship is primarily phoretic rather than nutritive; only the smallest glochidia and the haustorial larva grow substantially while on the host. Growth of the smallest larvae suggests a lower functional size limit of ∼150 μm for the juvenile stage. Most Ambleminae, the most diverse North American clade, infect host gills by attracting feeding fish. Many species of Pleurobemini and some Lampsilini release conglutinates of eggs and larvae that resemble host food items. Many Lampsilini and a few Quadrulini use mantle modifications to attract host fish to the female. The mantle of some Quadrulini forms a posterior chamber that holds glochidia for immediate release in response to host fish. In many Lampsilini, mantle flap lures and a protrusible marsupium promote attack by the host fish and direct extraction of glochidia from the marsupium by the host. Host extraction of glochidia from the brooding female might have favored the evolution of long-term brooding in Lampsilini because glochidia need not be released by the female to encounter the host. A remarkable derivative of the host extraction strategy evolved in Epioblasma, which catch fish between the valves and release glochidia directly to the trapped host before releasing it. Host specificity is a critical feature of the evolutionary diversification and conservation biology of Unionoida. As temporary parasites, mussels must primarily evade the innate immune responses of the host, rather than the adaptive (acquired) responses. Evolution of host specificity is associated with selective encounter of host taxa, either because of host attraction strategies or because of dominance of particular host species in the habitat. The intricate relationships between mussels and fish are easily disrupted and, thus, contribute to the imperilment of many mussel species, yet they also fascinate us and compel conservation efforts

Rotational Grazing Demonstrations with Beef Cows on CRP Land in Adams County

Two grazing systems have been demonstrated annually from 1991–2003 on CRP land near Corning, Iowa. This report summarizes the 2003 production data. A 13-paddock intensive-rotational grazing system and a 4-paddock rotational grazing system were established in 1991 to show economically feasible grass alternatives to row crops and CRP participation on steeply sloping (9–14% slope), highly-erodible land (HEL)

Pasture Weaning Calves in a Rotational Grazing Demonstration with Beef Cows in Adams County in 2006

Weaning calves on grass is a management technique for reducing calf stress and decreasing health issues at weaning time in a beef cow/calf operation. 2006 was the third year for demonstrating this management technique at the Adams County CRP Research and Demonstration Project Farm near Corning, IA. This report highlights the 2006 grazing production data and compares it with 15 years of grazing production at that site

Pasture Weaning Calves in a Rotational Grazing Demonstration with Beef Cows in Adams County, 2004

Two cow/calf rotational grazing systems were demonstrated annually from 1991 to 2003 on CRP land near Corning, Iowa. These systems were a 13-paddock intensive rotational grazing system and a 4-paddock rotational grazing system. In 2004, these systems were combined into one system to demonstrate weaning of calves on grass. This report highlights the 2004 production data for this grazing demonstration
