Nebraska Beef Cattle Reports

A 2- year study evaluated the effect of corn residue baling or grazing on subsequent yields, as well as, nutrient removal by baling at five locations in Nebraska. Three treatments were applied to each field: baled, grazed, and control (no baling and no grazing). Grain and stover yields were measured by hand harvest at maturity. No differences were observed among treatments for corn yield with baled having yields of 234 bu grain / acre, grazed with 239 bu grain / acre and control with 223 bu grain / acre. Th ere was no difference in stover yield among treatments (8,326, …


Effect Of Heifer Development System On Reproduction And Subsequent Gain As A Pregnant Heifer, Shelby A. Springman, Hazy Rae Nielson, Tonya L. Meyer, Mike Kirby, Jim Teichert, Richard N. Funston Jan 2017

Effect Of Heifer Development System On Reproduction And Subsequent Gain As A Pregnant Heifer, Shelby A. Springman, Hazy Rae Nielson, Tonya L. Meyer, Mike Kirby, Jim Teichert, Richard N. Funston

Nebraska Beef Cattle Reports

Weaned heifers grazed corn residue, upland range, or were fed 1 of 2 drylot diets differing in energy. Heifer development diets did not impact their resulting AI or final pregnancy rates. Cost per pregnant heifer was similar among treatments. A subset of AI- pregnant heifers was placed in a Calan Broadbent individual feeding system during late gestation. As a pregnant heifer, feed efficiency was not impacted by development system. These results indicate producers may utilize their most readily available and/or cost- effective feed resources with no detriment to pregnancy rates or feed efficiency as first- calf heifers.


Pseudoscorpions Of The Family Cheiridiidae (Arachnida: Pseudoscorpiones) Recovered From Burial Sediments At Pachacamac (500–1,500ce), Peru, Johnica J. Morrow, Livia Taylor, Lauren Peck, Christian Elowsky, Lawrence Stewart Owens, Peter Eeckout, Karl Reinhard Jan 2017

Fragmented remains of pseudoscorpions belonging to the family Cheiridiidae (Arachnida, Pseudoscorpiones) were recovered from Ychsma polity (c. AD 1000–1475) burial sediments from Pachacamac, Peru. Sediments from 21 burials were examined following rehydration in 0.5% trisodium phosphate for 48 h and subsequent screening through a 250 lm mesh. Materials larger than 250 lm were surveyed for the presence of arthropods. A total of two samples contained pseudoscorpion fragments, which were collected and quantified to determine the minimal number of pseudoscorpions present per gram of each sample. Following quantification, pseudoscorpion specimens were imaged utilizing confocal laser scanning microscopy (CLSM) to assist with …

Pollen analysis was applied to a mummified homicide victim in Nebraska, U.S.A., to determine the location of death. A control sample showed the normal ambient pollen in the garage crime scene. Ambient windborne types, common in the air of the region, dominated the control. Internal samples were analyzed from the sacrum, intestine, and diaphragm. Microfossils were recovered from the rehydrated intestine lumen. The intestinal sample was dominated by Brassica (broccoli). The sacrum sample was high in dietary types but with a showing of ambient types. The pollen from the diaphragm was dominated by ambient pollen similar to the control samples. …
