A gestation sow feeding system has a sow bedding enclosure, a gated scale weighing station, an alley connecting the scale weighing station with two separate feeding pens having entry and exist gates, and a bypass gate connecting the alley and the bedding enclosure. The traffic of sows through the system is monitored and controlled by a computer which controls the gates of the system, measures the weight and average daily gain of each sow weighed, and directs the weighed sow to the feeding pen for a ration of feed to permit the sow to adjust to a targeted average daily ...

Although properly managed grazing can increase farm income and enhance environmental quality, it has not been widely used in the Upper Midwest. Instead, grazing has been viewed as an adjunct to row crop production, and state-of-the-art management techniques have been adopted slowly. However, recent research has developed forage grazing systems that can compete economically with row crops, especially on more erodible land. In order to implement such systems successfully, producers need practical information on the technical aspects of grazing and pasture management. Most grazing videos produced prior to this project were tailored to other geographic regions or weren't sufficiently ...


Low-Input Sustainable Sow Housing For Iowa, Mark S. Honeyman, Steven J. Hoff, James Mckean, Dwaine S. Bundy, Emmett Stevermer Jan 1996

This project developed a low-cost, innovative sow housing and feeding system that is currently under consideration for a patent. A quasi ad libitum (free feeding of a controlled diet) electronic feeding system for gestating sows was housed in a 9.1 X 18.3 meter steel-hooped structure covered with an aluminized plastic tarp. A feeder served as a partition between high-energy and low-energy diet feeding areas. After weighing, hogs were directed to the appropriate diet by means of a tag number read by a computer. Such farm size-neutral housing can help producers raise lean market pigs. Other advantages include improved ...

Farmer-feeders who feed homegrown crops to feeder cattle as a marketing alternative for these crops must evaluate the impact of their cropping patterns and feeding on the whole farm operation. This project developed a tool for beef cattle producers to make more conscientious decisions
