An experiment was conducted to evaluate feeding transgenic corn containing the cry34Ab1 and cry35Ab1 genes from a Bacillus thuringiensis strain and the phosphinothricin acetyltransferase (pat) gene from Streptomyces viridochromogenes to finishing cattle compared with nontransgenic corn. Expression of the cry34Ab1 and cry35Ab1 genes confers resistance to corn rootworms, and the pat gene confers tolerance to herbicides containing glufosinate-ammonium. Sixty crossbred steers (396 kg) were individually fed either transgenic corn (DAS-59122-7; 59122), a near-isogenic, nontransgenic control (Control), and a conventional, nontransgenic corn for 109 d to evaluate nutritional equivalency (20 steers/treatment). The corn was coarsely rolled (geometric mean diameter = 4,200 …

Trends In Sandhill Crane Numbers In Eastern New Mexico, James B. Montgomery Jr.
Proceedings of the North American Crane Workshop
Following a 1980s decline in the number of cranes in the Bitter Lake National Wildlife Refuge area of the Pecos River Valley in eastern New Mexico, peak fall migration numbers increased from 5,640 in 1989-90 to 15,790 in 2003-04 and 13,650 in 2004-05. Concurrently, hectares of corn grown for silage to feed dairy cows increased from 1,781 in 1989 to 8,013 in 2003 and 7,325 in 2004. The population goals of the NM Department of Game and Fish are being met but a downturn in the dairy industry could result in a decline in crane numbers.
