Examination of microbial ecosystem in rumen may help improve cow performance and reduce methane emissions.

Dairy

Basics of NIRS forage and feed analysis for dairy feed

While it maybe the preferred ingredient analysis method, not all NIRS are created equal

February 9, 2018

Helen Warren

Near-infrared spectroscopy (NIRS) has become the analytical method of choice for the analysis of many feed materials, particularly forages.

Dairy

Advances in ruminant environmental impact reductions

Examining recent developments in the study of rumen microbial ecosystem, genetic selection

January 9, 2018

Helen Warren

To reduce the impact ruminants make on the environment, the dairy industry must take a holistic approach to improving production efficiency, which includes the importance of the rumen microbial ecosystem and its role beyond simply providing nutrients to the animal.

Minerals

How to properly assess dairy cow trace mineral status

No single simple analysis can accurately profile minerals in ruminants

October 11, 2017

Helen Warren

Despite many testing options, there is no single analysis for the assessment of the mineral status of dairy cows so it is critical to choose wisely before making your determination.

Dairy

Forage analysis crucial to accurate ruminant rations

NIR analysis aids in combating variability, identifying accurate nutrient, mineral parameters

August 16, 2017

Helen Warren

The use of NIR analysis aids in combating forage variability by identifying accurate nutrient and mineral parameters in dairy rations.

Health

How to mitigate antimicrobial resistance in livestock

Recent UK research poses recommendations for antimicrobial stewardship in farm management

July 11, 2017

Helen Warren

The reduction of unnecessary antimicrobials in agriculture and their dissemination into the environment reduces resistance risk.

Dairy

How nutrition influences dairy cow health, immunity

Balanced nutrition greatly affects immune function, performance in transition cows

May 26, 2017

Helen Warren

Oxidative stress and several other issues can decrease dairy cow immunity and productivity. Luckily, proper nutrition can mitigate these effects.

Dairy Nutrition

How to prevent milk fever in dairy cows

Prevention strategies include manipulation of the cow’s close-up diet post-calving

June 14, 2016

Helen Warren

Hypocalcaemia, or milk fever, is a common issue in dairy farming. Cows with milk fever are at greater risk of other metabolic disorders so prevention should be the focus. Prevention usually involves manipulation of the close-up diet.
