Mineral Sources May Impact Reproductive Efficiency
Jonathan Sumption, Dr. Rosie Nold
South Dakota State University
Advancements in reproductive technologies have improved production efficiency of beef cattle in the world and continue to do so at a rapidly increasing rate. Many producers are familiar with embryo transfer. Another form of embryo collection is called in-vitro fertilization or ovum pick up (OPU) which harvests unfertilized oocytes directly from the ovaries of a donor cow or heifer.
Bladder Stones in Cattle
Dr. Ken McMillan
If these stones are large enough, they can block the urethra, and the animal cannot urinate. This is more common in males because the urethra is smaller. In cattle, sheep and goats, the urethra has an “S”-shaped bend called the “sigmoid flexure” that straightens out when the animal has an erection. This bend makes passing stones even more difficult, and that sigmoid flexure is the most common place where we see cattle block.
Fall Calf Market Expected to be Driven by Higher Corn Prices with Limited Potential for Upside
Oklahoma Farm Report
According to the Livestock Marketing Information Center’s director, Katelyn McCullock, the crazy weather that has impacted the 2019 corn crop is likely to result in higher corn prices in the coming months, as well as lower feeder cattle prices.
Detecting Pregnancy in Heifers and Cows with Technology
University of Nebraska
Two technologies that are available to producers to utilize to detect pregnancy in heifers or cows are blood tests and ultrasound. These two technologies can be utilized to detect pregnancy as early as 30 days post breeding. Early detection of pregnancy in beef heifers or cows provides producers with information that allows them to make timely management decisions. A recent article Choosing a Method for Pregnancy Diagnosis discusses the use of these two technologies.
Drug combination effective against bovine leukemia
Scientists have succeeded in reducing levels of the bovine leukemia virus (BLV) in cows with severe infections by combining an immune checkpoint inhibitor and an enzyme inhibitor, according to Hokkaido University in Japan, which suggested that the finding could be utilized to control other diseases in cattle and, perhaps, in people someday.
What Does the Future Hold? Cattle Breeding Techniques
North Dakota State University
As we make progress in the field of animal breeding and selection, many “new” technologies surface. Visual appraisal was complemented with performance records, expected progeny differences, ultrasound evaluation of carcass traits and, in recent times, genetic marker evaluation of economically important traits.
Mud-free cattle watering improves environment
Tom J Bechman
If you’ve fought mud in a livestock operation this year, you’ll appreciate what Ted Willer did to reduce mud around areas where his cattle congregate to drink. Willer manages Willer Timber Ridge near Greencastle, Ind. It’s a seedstock operation primarily providing commercial bulls for Angus producers across the country.
