Transition cow: Immune suppression or a state of immune robustness?

julieannopgenorth@gmail.com — Tue, 17 Dec 2024 00:00:00 -0500

Fresh cows are more susceptible to disease than at any other point in their lactation, and this is traditionally attributed to a suppressed immune system around calving.

Lipopolysaccharides – The Internally Generated Threat

Fri, 31 May 2024 00:00:00 -0400

The body has several physical barriers to “outside” threats, the skin, the respiratory linings and the digestive tract. Of these three, the digestive tract faces the most potential threats, not only from what is ingested but also from what develops in situ, through the growth of microorganisms, the toxins some produce and even the remnants of those that die within the tract. Pathogenic bacteria normally exist within the gastrointestinal (GI) tract. Common ones include species of Salmonella and E. coli. Both these bacteria are gram-negative (G-), meaning they have cell walls that will not accept that stain. These bacteria can lyse, and their cell walls are broken into segments that contain “endotoxin” made of lipopolysaccharides (LPS).

Estimating return on investment of 3D cameras in dairies

The integration of 3D imaging technology systems into dairy management practices offers a blueprint for the future where technology-driven solutions enable farms to go through the complexities of modern dairy production more effectively.

Fat mobilization: Connecting metabolic and infectious diseases in transition cows

contre28@msu.edu — Sat, 25 Mar 2023 09:11:55 -0400

Transition cow diseases often present as complexes of metabolic and infectious diseases: a common case being a cow with a retained placenta that develops ketosis a few days later. How are these diseases connected and what causes their high rates of recurrence? One of the answers is fat mobilization.

Economic impact of subclinical hypocalcemia

Before discussing subclinical hypocalcemia, it is helpful to review the more obvious disease of clinical hypocalcemia, or what everyone knows as milk fever. This disease can occur in mature dairy cows within three days after calving.

Circadian pattern of blood energy metabolites – Timing matters

When dairy cows transition from late gestation to early lactation, they often enter a state of energy deficit as increased energy demands are not met by the level of intake.

Something is robbing your fresh cows’ calcium stores – and it’s not milk production

Late at night, after the drone of the pumps are quiet, every producer has wondered, “How could I get more out of my cows?” As most good questions do, this too leads to another question. “Nutritionally, what is holding fresh cows back from maximum production?”

Subclinical hypocalcemia impacts cows and profitability

tim.brown@dairynutritionplus.com — Fri, 18 Oct 2019 13:00:01 -0400

Hypocalcemia impacts cows on all types of dairies. Historically, dairy producers have focused on clinical hypocalcemia, often called milk fever, because without treatment these cows don’t recover.

Detoxifying free radicals to alleviate oxidative stress

Tue, 11 Jun 2019 13:00:01 -0400

Prevention and treatment of oxidative stress (OS) could be the solution to many of the dairy health, production and welfare issues of our time. Dr. Melissa Behr of the South Dakota State Diagnostic Lab believes “oxidative stress is the backbone of all diseases and cancer in mammals.”

Keep your cows healthy by controlling stress

Thu, 06 Jun 2019 14:48:07 -0400

Ensuring your cows are healthy will improve their productivity, longevity, fertility and resistance to disease, along with reducing the costs of upkeep. A key to this well-being is controlling and limiting their stress.

Postpartum ketosis treatments – propylene glycol, dextrose or both?

sm682@cornell.edu — Fri, 20 Jul 2018 17:28:04 -0400

Postpartum ketosis, or hyperketonemia, is defined as an excessive increase of ketone bodies in the blood and is a common metabolic disorder of dairy cows.

How technology advances can help battle ketosis

sureshraja@dal.ca — Fri, 17 Apr 2015 07:00:00 -0400

Ask any dairy farmer what type of issues they face in today’s industry, and the conversation undoubtedly will move toward money. With most farmers facing decreasing profit margins and some barely hanging on due to increased cost and a stagnant revenue stream, good farmers are always on the lookout for ways to better manage their bottom line.

New study confirms one of fresh cows’ biggest challenges

bill.zimmer@bio-vet.com — Wed, 29 Feb 2012 07:00:00 -0500

Researchers from Cornell University and the University of Wisconsin recently published results from a field trial looking at the effects of propylene glycol on milk yield and resolution of ketosis in fresh cows diagnosed with subclinical ketosis in the Journal of Dairy Science.
