Podcasts about milk fever

Dr. Hernandez recently presented a Real Science Lecture series webinar on this topic. You can find the link at balchem.com/realscience.Dr. Hernandez begins with an overview of how she came to study calcium metabolism in the mammary gland. Over the past number of years, she has worked on research to manipulate what's happening in the mammary gland in the prepartum period to ensure adequate endocrine, nutritional, reproductive, and immunological status. (5:55)The panelists discuss how “normal” has changed when it comes to transition cow health. Dr. Overton reminds listeners that 25 years ago, 6-8% of fresh cows in a herd having clinical milk fever was pretty typical. Now, we accept none of that. Subclinical hypocalcemia was not on the radar then, and we thought we had calcium all figured out. Dr. Hernandez's work shows that this was not the case. She is pleased that a synergism of producers, veterinarians, and academics have been working together to understand the mechanisms of calcium metabolism to find solutions for individual farms based on their situation. (9:22)Dr. Hernandez then discusses various interventions used in the industry, including low-potassium diets, negative DCAD diets, and zeolite clays. The clays are new to the US, and it seems that they work primarily through a phosphorus reduction mechanism and are best limited to feeding 10-14 days pre-calving. (18:14)Dr. Overton asks Dr. Hernandez about a point in her webinar that cows are in negative calcium balance through 150-200 days in milk. She confirms that there are approximately 8.5 kilograms of calcium in the bones of a cow, but we don't know how much of that she loses each lactation. Her dream scenario would be a CT scanner large enough to fit a dairy cow in to evaluate how her bones change throughout lactation. This leads to a discussion of whether or not we should be including higher rates of calcium in dairy cow diets. Dr. Hernandez would like to learn more about what's happening with calcium absorption in the gut in real-time with endocrine status and stage of lactation, which is a challenging task. (23:17)Co-host, Dr. Jeff Elliott, asks if the reason multiparous cows are more prone to milk fever is because they're not as efficient at calcium resorption to the bone. Dr. Hernandez doesn't have a definitive answer, but it could be due to less effective gut absorption with age, or it may be related to the influence of estrogen on bone density. She also mentions it could be endocrine-controlled or even stem cell-related.  (28:59)Dr. Hernandez's hypothesis has always been that you have to have a calcium decrease to trigger the negative feedback loop involved in calcium metabolism. Her advice is to wait until 48 hours to take a blood sample to analyze calcium. This aligns well with epidemiological research on the veterinarian side regarding delayed, persistent, transient, and normal hypocalcemic animals. (33:04)Dr. Overton asks about a calcium-chelation study that Dr. Hernandez's group conducted and whether or not chelating calcium had an impact on colostrum production. It did not in that experiment. Dr. Hernandez was surprised at how much chelating agent was needed to overcome the draw of the mammary gland, but that further underlines how much of a priority lactation is in metabolism. (41:45)Scott asks both panelists their views on what the priority should be for research in this area. Dr. Hernandez's ideas include more research on how zeolite clays work biologically, finding out what's happening in the gut, mammary gland, and bone of a dairy cow at different stages of lactation. She emphasizes that research should be conducted at different stages rather than just extrapolating from one stage to another because lactation is incredibly dynamic. Dr. Overton seconded the idea of a better understanding of zeolite clays and their feeding recommendations, as well as research defining what happens to and where all the calcium is pulled from the bone during lactation. (45:32) In closing, Jeff, Tom, and Laura share their take-home thoughts. Jeff is excited to learn more about how zeolite clays work and if other products may come to the forefront to help in calcium metabolism management. Tom commends Laura on her work and how it has dovetailed so well with the epidemiological research from the veterinary side. Laura reminds listeners that the mammary gland is running the show and is thrilled that her work as a basic scientist is having an applied impact on the dairy industry.

Nutritionists are often blamed for transition cow problems like high NEFAs, clinical and subclinical ketosis, and subclinical hypocalcemia. Dr. Baumgard suggests these symptoms are a result of one of two situations: 1. These are highly productive, healthy, and profitable cows; or 2. The symptoms are the metabolic reflection of immune activation, likely stemming from metritis, mastitis, pneumonia, or GI tract inflammation. In the first scenario, the nutritionist deserves a raise; in the second, these are mostly management issues not caused by nutrition. (1:26) If listeners are interested in more detail on this topic, Dr. Baumgard suggests reading this 2021 review in the Journal of Dairy Science: “ Invited review: The influence of immune activation on transition cow health and performance—A critical evaluation of traditional dogmas.” Link: https://www.sciencedirect.com/science/article/pii/S0022030221006329Dr. Baumgard highlights key concepts that underpin his thinking regarding transition cows: The best indicators of health are feed intake and milk yield, it's too easy to overthink the immune system, Mother Nature is rarely wrong, and inconsistent or non-reproducible data should create doubt. He goes on to review the incidence of metabolic disorders in early lactation and the energy balance dynamics of the transition period. (4:29)For decades, we've had the assumption that NEFAs and ketones are causing many of the health issues in transition cows. NEFAs, BHBs, and calcium have been correlated and associated with negative outcomes. However many other studies do not find these negative correlations or associations. Plasma NEFA is markedly increased following calving in almost all cows, yet only 15-20% get clinical ketosis. Dr. Baumgard suggests that it's presumptuous and reductionist of us to assume we can use one metabolite to diagnose the disease. Little mechanistic evidence exists to explain how these symptoms cause metabolic disease issues.  (10:29)If hyperketonemia, high NEFA, and subclinical hypocalcemia are causing disease, then therapeutically treating these disorders would improve overall cow health. NAHMS data does not back that up. Dr. Baumgard dissects the dogma of ketosis. In short, mobilization of adipose tissues and partial conversion of NEFA to ketones is essential for maximum milk yield. (18:35)High-producing cows are more hypoinsulinemic compared to low-producing cows, and transition period insulin concentrations are inversely related to whole lactation performance. Low insulin concentrations coupled with insulin resistance allow for fat mobilization. (29:02)Post-calving inflammation occurs in all cows. Sources include the mammary gland, the uterus,  and the gut. Severe inflammation precedes the clinical presentation of the disease. In one experiment, all cows exhibited some inflammation in very early lactation. However, cows that were culled or died before 100 days in milk were already severely inflamed during the first few days of lactation. Dr. Baumgard thinks inflammation is the simplest and most logical explanation for why some cows don't eat well before and after calving.  (31:13)While clinical hypocalcemia (milk fever) is pathological and requires immediate intervention, is subclinical hypocalcemia detrimental to health, productivity, and profitability? (36:33)Dr. Baumgard's paradigm-shifting concept suggests that increased NEFA and hyperketonemia are caused by immune activation-induced hypophagia, and hypocalcemia is a consequence of immune activation. He goes on to use a high-producing, a low-producing, and a sick cow to illustrate this concept. (43:26)In summary, the metabolic adjustments in minerals and energy during the transition period are not dysfunctional and don't need to be “fixed.” The real fix is to prevent immune activation in the first place to prevent the cow from going off feed. Profitable production is a consequence of wellness. (52:19)Dr. Baumgard takes a series of engaging questions from the webinar audience. Watch the full webinar at balchem.com/realscience.

Milk + Fever = Disaster...According to Dave 10/15/24

This episode of the Real Science Exchange podcast was recorded during a webinar from Balchem's Real Science Lecture Series.Dr. Goff sees three main challenges for transition cows: negative energy and protein balance, immune suppression, and hypocalcemia. About half of all older cows experience hypocalcemia, and around 3% will experience milk fever. Cows develop hypocalcemia if they are unable to replace the calcium lost in milk from either their bone or diet. Compared to the day before calving, a cow needs around 32 extra grams of protein the day of calving to meet her increased requirements. (2:00)Dr. Goff reviews the pathways of calcium homeostasis and the actions of parathyroid hormone (PTH). Aged cows may have a harder time maintaining calcium homeostasis due to the loss of vitamin D receptors in the intestine with age and fewer sites of active bone resorption capable of responding quickly to PTH once they have finished growing. Blood pH plays a role in calcium homeostasis: when blood pH becomes alkaline, animals become less responsive to PTH. Dr. Goff reviews the impacts of high vs low DCAD diets and reviews the amount of time it takes for the kidney and bone to respond to PTH. (4:20)There are several strategies to reduce the risk of hypocalcemia. One is to reduce dietary potassium so the cow is not as alkaline. Using forages from fields that have not had manure applied to them is one way to accomplish this. In addition, warm-season grasses (corn) accumulate less potassium than cool-season grasses, and all grasses contain less potassium as they mature (straw). A second strategy is to add anions such as chloride or sulfate to the diet to acidify the blood to improve bone and kidney response to  PTH. Research has shown that sulfate salts acidify about 60% as well as chloride salts. The palatability of anionic diets has led to commercial products such as Soychlor. (13:06)Dr. Goff then discusses the over- and under-acidification of diets and gives his opinion on the appropriate range of urine pH for proper DCAD diet management, including a new proposed DCAD equation to account for alkalizing and acidifying components of the diet. He also gives some options for pH test strips to use for urine pH data collection. (18:30)Dr. Goff's lab has found that as prepartum urine pH increases, the calcium nadir decreases. The inflection point is right around pH 7.5, where above 7.5 indicates a higher risk of hypocalcemia. Data from other researchers suggests that urine pH lower than 6.0 may result in lower blood calcium, indicating an overall curvilinear response. Low urine pH (under 6.0) has also been associated with a higher incidence of left-displaced abomasum. (29:02)Moving on to other minerals, Dr. Goff discusses phosphate homeostasis and how that interacts with calcium in the close-up cow. Feeding too much phosphorus can decrease calcium absorption and feeding low phosphorus diets before calving can improve blood levels of calcium. He recommends less than 0.35% phosphorus in close-up cow diets. For magnesium,he recommends 0.4% prepartum and immediately postpartum to take advantage of passive absorption across the rumen wall. (31:08)Another strategy to reduce milk fever risk is to reduce dietary calcium prior to calving to stimulate parathyroid hormone release well before calving. A zeolite product that binds calcium is now available and may make this much easier to achieve. (42:59)In closing, Dr. Goff reminds the audience that some level of hypocalcemia post-calving is normal and in fact, is associated with higher milk production. The key is making sure that the cow's blood calcium levels can bounce back to normal by day two after calving.
