Whole genome sequencing provides insight on the future of food safety

Salmonella

Food production industries continue to make improvements in pathogen reduction and improving public health. One of the ways in which this is accomplished is through improvements in food safety diagnostics.

Next generation sequencing and genomics provides processors with previously unavailable information on strains, sources, and identity of particular pathogens or spoilage issues. Next […]

Superior genes leads to $251,000 sale of dairy calf

Last month a 12-week-old Australian Holstein dairy heifer calf, known as Jedi Gigi, sold at auction for $251,000 — the second highest price ever paid for a bovine (beef or dairy) in Australia’s history. This sale will also be the first time an Australian dairy animal will be live exported to the U.S.

Taking into […]

Genetic study results may be a win for rats

Devouring food supplies and spreading a range of harmful viruses and bacteria, most can agree that rats wreak havoc no matter where they go. However, what has been previously unknown is the question on how rats went from wild rodent to unwanted human companion. Now, a new genetic study of brown rats from around the […]

Genomics uncorks climate-tolerant wine grape varieties

Just in time for wine Wednesday, scientists have discovered a new sequencing process that will help breed grapes that can tolerate climate change.

Using this sequencing process, along with a new computer algorithm that can yield detailed information about complex genomes of various organisms, scientists were able to assemble the genome of the cabernet sauvignon […]

Hereditary disorders in dogs more common than initially thought

Considered to be the most comprehensive study on canine hereditary disorders, researchers recently tested nearly 7,000 dogs from about 230 different breeds and found that a lot of canine hereditary disorders are more widespread than originally believed.

According to a report from the University of Helsinki, the team tested the dogs for predisposition to almost […]

Genomic testing can help limit cases of BVD in cattle

Since its discovery in 1946, bovine viral diarrhea (BVD) has been a continuing problem of the cattle industry. In infected cattle, the virus can lead to decreased reproduction, lower feed efficiency, higher mortality and morbidity rates — contributing to astronomical costs for cattle farmers around the world.

Adding up the cost is a daunting task, […]

Study seeks to find out if GMOs actually use more or less pesticides

As opinions continue to swirl in the debate regarding the benefits of genetically modified crops (or GMOs) scientists at Iowa State made a fresh attempt to answer one seemingly simple question: Did the development of those crops lead to more use of pesticides, or less?

To find this answer, the scientists used data from a […]

Research unravels genetic ancestry of the strawberry

After four years of research, scientists from the University of New Hampshire (UNH) have unlocked a major genetic mystery of one of the ancestors of cultivated strawberry, known as Fragaria iinumae. Through their work with Fragaria iinumae, they will be able to better understand the cultivated strawberry, which is known as one of the most […]

Research finds horse’s genetic makeup influences cancer causing virus

Sarcoid skin tumors are the most common form of cancer in horses, but little is known about why the papillomavirus behind them strikes some horses and not others. That was, until now.

A new study led by scientists at the Baker Institute for Animal Health at Cornell’s College of Veterinary Medicine shows that genetic differences […]

How and when to collect DNA samples to produce the best genomic test results

As the use of genomics has entered mainstream dairy production, lots of attention has been focused on the science, technology, predictability and economics of genomic testing.

But all the benefits the latest advancements in high-tech dairy genomics have to offer to dairymen rely entirely on a critical, and decidedly low-tech, first step: the collection of […]
