Exploring The Pathogen Profiles Of Ancient Feces, Drew Capone, David Holcomb, Amanda Lai, Karl Reinhard, Joe Brown
Karl Reinhard Publications
Analysis of ancient desiccated feces – termed paleofeces or coprolites – can unlock insights into the lives of ancient people. We collected desiccated feces from caves in the Rio Zape Valley in Mexico (725-920 CE). First, we extracted DNA with methods previously optimized for paleofeces. Then, we applied highly sensitive modern molecular tools (i.e., PCR pre-amplification followed by multi-parallel qPCR) to assess the presence of 30 enteric pathogens. We detected ≥1 pathogen associated gene in each of the ten samples and a mean of 3.9 pathogens per sample. The targets detected included Blastocystis spp. (n=7), atypical enteropathogenic E. coli (n=7), …

Nebraska Beef Cattle Reports
Summary with Implications
A sorghum-sudangrass hybrid was swath grazed by growing steers (529 ± 18 lb) from November 2023 to January 2024. Treatments were offering new forage once (1X) or twice (2X) per week to determine the effect of allocation frequency on animal performance and forage utilization. Average daily gain was not impacted by treatment (1X = 0.45 ± 0.1 lb/day, 2X = 0.45 ± 0.1 lb/day). Pre-and post-graze biomass samples were collected to estimate forage utilization, which was not different between treatments (1X = 57.1 ± 3.6%, 2X = 61.1 ± 3.6%). However, there was a difference in carrying …

Artificial Insemination Of Beef Heifers With Multi-Sire Semen, Dempster Christenson, Jordan M. Thomas, Daniel J. Kelly, Richard N. Funston
Artificial Insemination Of Beef Heifers With Multi-Sire Semen, Dempster Christenson, Jordan M. Thomas, Daniel J. Kelly, Richard N. Funston
Nebraska Beef Cattle Reports
This study compared pregnancy rates of beef heifers artificially inseminated with multi-sire semen to single-sire semen. It was hypothesized pregnancy rates resulting from multi-sire semen would be increased compared to single-sire semen. Heifers were artificially inseminated with semen from one of three single-sires or semen from a combination of the same three sires. Pregnancy rates did not significantly differ. Paternity testing suggests sire parentage can be unequal when semen is mixed from multiple sires. In summary, producers can expect similar pregnancy rates using single-sire and multi-sire semen, but progeny may have unequal sire representation.

Nebraska Beef Cattle Reports
Summary with Implications
Heifers developed to lower rates of overwinter gain may reduce development costs without growth and reproduction impacted. A 3-year study was conducted to evaluate different overwinter rates of gain on heifer growth rates, reproductive, and economic performance. Heifers were managed together and individually supplemented (January-May) with dried distillers grains to achieve either a low (0.75 lb/d) or high (1.50 lb/d) average daily gain. At breeding, high gain heifers were heavier than low gain heifers. Average daily gain and body condition score were similar between treatments. Overwinter treatment did not impact attainment of puberty, pregnancy rates, or the …

Impact Of Pre- And Post-Breeding Supplementation On Performance Of May-Born Heifers, Josie N. Crouch, J. Travis Mulliniks, Jacki A. Musgrave, Kacie L. Mccarthy
Nebraska Beef Cattle Reports
Summary with Implications This 3-year study compared growth, reproductive performance, and economics of May-born yearling heifers that either received 2.00 lb/ heifer/ per d of a dried distillers grain supplement from pre-breeding (July) through breeding (August) or no supplement. Supplementation was offered approximately 24 days before breeding, averaging 55 days total. Heifer body weight was unaffected by supplementation. Supplementation increased average daily gain until pregnancy diagnosis, but no differences were noted after pregnancy diagnosis. Providing dried distillers grain increased the percentage of heifers that were cycling before breeding; however, no differences in pregnancy rates, percent that gave birth in the …

Nebraska Beef Cattle Reports
Summary with Implications
By accurately assessing the amount of forage available, producers can estimate the pasture carrying capacity to make informed decisions on management. To provide producers with a feasible and efficient approach to estimate forage mass, this project evaluated performance of two image analysis tools, Crop Canopy Image Analyzer (CCIA) and Canopeo, in estimating forage mass for cereal rye. Forage mass measured by clipping the forage (areas with 5.625 ft2) was correlated with plant cover analyzed by the two tools using photos of the forage taken 37 in above the ground. Results obtained have supported the feasibility …

Metallic Nanoparticles And Cosmetics: The Role Of Mitochondria And Premature Aging, Veronica Montesinos-Cruz, Justin Olmanson
Department of Teaching, Learning, and Teacher Education: Faculty Publications
The cosmetic industry has developed and commercialized numerous products using new technologies, making them increasingly appealing to the public. The use of metallic nanoparticles (MtNPs) as key ingredients in cosmetics has become more widespread due to their demonstrated benefits. However, the use of these products remains controversial, as some studies have shown that MtNPs can penetrate the deeper layers of the skin and disrupt homeostatic balance. It has also been demonstrated that the interaction between MtNPs and keratinocytes increases the generation of reactive oxygen species (ROS), which can lead to oxidative stress, a condition associated with premature aging. Mitochondria, as …
