An Update On Retained Ownership: Case Study Of Calves Born At The Antelope Range Livestock Station, D. M. Marshall Jan 1992

An Update On Retained Ownership: Case Study Of Calves Born At The Antelope Range Livestock Station, D. M. Marshall

South Dakota Beef Report, 1992

An update to a previous report on the case history of retained ownership in the Antelope Range Livestock Station herd is provided. Calves born in 1990 and 1991 were placed in a custom feedlot following weaning and the profitability of postweaning feedlot performance was estimated. Retaining ownership through slaughter, as opposed to selling calves at weaning, resulted in additional estimated profits of $51.27 and $107.82 per head (excluding interest on calf) for the 1990-born and 1991-born calf crops, respectively.

Leopold Center Completed Grant Reports

Soil erodes over six times faster from cultivated Iowa cropland than from pastureland, even though almost 12 percent more of the pastureland acres are classified as highly erodible than the cropland acres. Because of serious concern about excessive erosion of Iowa's topsoil, profitable alternatives to row-crop production are needed for soils like those found in much of southern Iowa.

History And Economic Impact Of Crane-Watching In Central Nebraska, Gary R. Lingle Jan 1992

History And Economic Impact Of Crane-Watching In Central Nebraska, Gary R. Lingle

Proceedings of the North American Crane Workshop

The first documentation of the Platte and North Platte rivers' importance to sandhill cranes (Grus canadensis) dates from the late 1800's. Except for a few ornithologists, it was not until the mid-1970's that crane-watching became popular. During the last 10 years, this interest has become a multi-million dollar tourist industry that attracts people from around the globe who seek to witness this vernal spectacle of half a million cranes. More than half of the former riverine habitat has been abandoned by the cranes, largely because of irrigation and hydropower projects that drain the river and enable forests to ...
