Seaweed cuts cow burp methane

Category : Dairy

Australia’s Commonwealth Scientific and Industrial Research Organization has identified a strain of seaweed that can reduce the methane emissions of cattle burps by more than 99 per cent if added to cattle feed in small amounts.

Asparagopsis taxiformis, which grows in the tropical coastal waters of Queensland, Australia, appears to almost totally disrupt the action of gut enzymes that produce methane, keeping feed energy in the animal instead of being released into the atmosphere.

Getting to know robo-mom

Category : Dairy

University of Guelph researchers are studying the design features of automated feeding stalls. That’s to see whether a calf’s learning process for using automated feeders can be accelerated. The goal of the project is to encourage equipment manufacturers to consider the animal’s needs when designing feeders alongside the practicality of their designs.

How one bull introduced a lethal gene into the Holstein breed

Category : Dairy

One of the most prolific bulls in the history of the Holstein breed also happened to carry a gene that has ultimately been responsible for an estimated half million spontaneous calf abortions worldwide. Researchers at University of California-Davis have now identified the responsible mutation, allowing farms to test for an avoid it. Pawnee Farm Arlinda Chief’s chromosomes account for almost 14 per cent of the genome in the current U.S. Holstein population.

Study confirms benefits of using beef genetics in dairy beef supply chain

Category : Dairy

A New Zealand study has confirmed that dairy farmers could produce high value calves with minimal calving difficulties using proven beef genetics. With the beef industry increasingly depending on dairy calves, there’s a need for better genetics for meat production to improve product quality.

How cow embryo health research can help human infertility

Category : Dairy

University of Guelph biomedical sciences professor Pavneesh Madan is studying embryo health in cows as a way of potentially increasing pregnancy success in women using in-vitro fertilization or embryo transfers. He is working with three Ontario infertility clinics to further study his cattle techniques to assess the health of human embryos.

Your food wrapped in milk?

Category : Dairy

The milk protein casein is the basis of a new packaging film that is degradable, edible and better at keeping food fresh than plastic. Scientists at the United States Department of Agriculture have created the milk-based food packaging, which has smaller pores than existing food wrap, making it up to 500 times better at keeping oxygen out.

Reducing iodine levels in milk

Category : Dairy

Dr. David Kelton of the University of Guelph is leading work to reduce iodine levels in milk. In collaboration with the Ontario Geological Survey and the University of Ottawa, his team is trying to establish whether cows’ drinking water may be an important iodine source. The Great Lakes were formerly a much larger inland sea filled with seaweed and iodine-rich deposits were left behind.

Estrogen levels in cow’s milk don’t affect humans, study shows

Category : Dairy

 

Scientists at the University of Ljubljana in Slovenia have shown that consuming estrogen in cow’s milk does not affect blood levels or reproductive health. Bovine milk contains naturally-occurring estrogens, and there has been concern that consuming cow’s milk with elevated estrogen levels could affect estrogen levels in humans, potentially leading to an increased risk of some cancers.
