Better Manage Progeny, Cattle Weight, Scours

Genomic Profiler for Heifers

Neogen GeneSeek (neogen.com) has a new gene screening product called Genomic Profiler Ultra-Low Density that will help predict the traits that beef seedstock pass along to their progeny. It’s more affordable and more powerful as a genotyping tool than previous tests, says Stewart Bauck of GeneSeek.

The product, which is typically bought through breed associations for about $30 to $35 per test, costs about one third as much as higher-density tests. Beef producers can use the tool to expand the genotyping of replacement heifers.

Genotyping of replacement heifers has several advantages.

  • Producers obtain predictions on genetic merit early in the life of replacement heifers, allowing for genomically assisted selection of future cows.
  • Seedstock breeders can add value to heifers with genomically enhanced expected progeny difference scores.
  • Commercial producers can improve their ability to select for maternal, performance, and carcass traits.
  • Genetic tests can reduce the time it takes to assess economically important traits, such as fertility and longevity.

“This test will improve the beef industry’s overall competitiveness by shortening generational intervals and improving selection accuracy,” Bauck says.

Weigh System

Gallagher (gallagher.com) has launched the W110 Entry Level Weigh System, a portable unit with a 3,300-pound capacity, for livestock and general-purpose weighing. The system retails for $999, and it’s the first with these capabilities in that price range.

“The W110 comes with a weigh-scale indicator, mounting bracket, and galvanized steel load bars,” says Scott Rooney of Gallagher.

“It allows for all-weather outdoor use, and it operates on four AA batteries. The plug-and-play system enables easy portability and convenience, making it very attractive to 4-H and FFA youth stock show activities and general livestock weighing,” he says.

BCV Vaccine

Merck Animal Health (merck-animal-health.com) has a new modified-live intranasal vaccine called Bovilis Coronavirus (BCV) to aid in the reduction of disease in calves and young cattle caused by BCV.

Most severe during winter months, BCV is often prevalent in cow/calf herds and dairy calves, and it is frequently diagnosed as the leading pathogen in young calves, says the company. The vaccine is approved for calves as young as 3 days old.

Ideally, says Scott Nordstrom of Merck, the combination of vaccinating cows and calves is the best practice.

Research shows the occurrence of scours in BCV-vaccinated calves was reduced by one third, and average duration of clinical signs was cut from about seven days to 84 hours.

BCV is available in 25-dose trays as well as in 10- dose and 50-dose bottles.
