Mineral Sources May Impact Reproductive Efficiency

Mineral Sources May Impact Reproductive Efficiency

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

Bladder Stones in Cattle

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.

Detecting Pregnancy in Heifers and Cows with Technology

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.

Feedstuffs

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

What Does the Future Hold? Cattle Breeding Techniques

Carl Dahlen

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.

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.
