Metabolic disorders in dairy animals are disturbances in metabolic processes that often occur around calving. Key periods are the last 3 weeks of pregnancy and the first 3 weeks of lactation due to hormonal and dietary changes. Common metabolic disorders include milk fever, ketosis, fatty liver disease, left displaced abomasum, and laminitis. Preventing these disorders requires careful management of nutrition, especially transition diets between dry and lactating periods.

Importance of Vitamins and Minerals for Dairy Cattle. The article written by Mr. Rakesh Kumar, Marketing Director, Growel Agrovet Private Limited, has been published in Dairy Planner magazine, March – 2021 edition.
Minerals Deficiencies in Poultry Causes ,Effect & Treatment.A deficiency of either calcium or phosphorus in the diet of young growing birds results in abnormal bone development even when the diet contains adequate vitamin D3 . A deficiency of either calcium or phosphorus results in lack of normal skeletal calcification. Rickets is seen mainly in growing birds, while calcium deficiency in laying hens results in reduced shell quality and osteoporosis. This depletion of bone structure causes a disorder that is commonly referred to as “cage layer fatigue.” When calcium is mobilized from bone to overcome a dietary deficiency, the cortical bone erodes and is unable to support the weight of the hen. A deficiency of manganese in the diet of immature chickens and turkeys is one of the causes of perosis and of thin-shelled eggs and poor hatchability in mature birds (also see Nutrition and Management: Poultry: Calcium and Phosphorus Imbalances). It can also cause chondrodystrophy.
The most dramatic effect of manganese deficiency syndrome is perosis, characterized by enlargement and malformation of the tibiometatarsal joint, twisting and bending of the distal end of the tibia and the proximal end of the tarsometatarsus, thickening and shortening of the leg bones, and slippage of the gastrocnemius tendon from its chondyles. Elevated intakes of calcium and/or phosphorus will aggravate the condition due to reduced absorption of magnesium by precipitated calcium phosphate in the intestinal tract.
In laying hens, reduced egg production, markedly reduced hatchability, and eggshell thinning are often noted. Deficiencies of both iron and copper can lead to anemia. Iron deficiency causes a severe anemia with a reduction in PCV. In color-feathered strains, there is also loss of pigmentation in the feathers. The birds' requirements for RBC synthesis take precedence over metabolism of feather pigments, although if a fortified diet is introduced, all subsequent feather growth is normal. Iron may be needed not only for the red feather pigments, which are known to contain iron, but also to function in an enzyme system involved in the pigmentation process.

This presentation is the first is a six part series on management of the ewe and doe from late gestation through weaning. This presentation covers late gestation: management and feeding.
transition period is an important period for milch animals. during this period feeding is also utmost important. During this time feeding and management decide the future of dairy animals.
This presentation by University of Maryland Extension Sheep & Goat Specialist Susan Schoenian discusses ewe nutrition from breeding until weaning and lamb nutrition from birth to weaning.
This is a presentation about getting reading for lambing and kidding. It was originally presented by University of Maryland Extension Sheep & Goat Specialist at the 2009 Lambing & Kidding School in Waldorf, Maryland.
Jan Kleinschmidt talks about the importance of nutrition from birth to weaning. She covers topics like preparing the dam, colostrum management, milk replacers, calf starter, feeding hay, and weaning.

The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
2. Metabolic disorders relates to disturbances of
one or more metabolic processes in the
animal/organisms
In dairy animals the time of disease is important
---- 3weeks before and after parturition
Influencing factors are
a. Hormonal changes
b. Moving from non-lactating to lactating stage
c. Changing of diet from roughages to highly
fermentable CHO
3. Metabolism is sum of
Physical
Chemical
Metabolic processes
relating to absorbance and breakdown or
synthesis of necessary organic molecules in
body
Disturbance of one or more metabolic
processes related to regulation of a certain
metabolites in the body fluids is known as
metabolic disorders
4. Traditionally it is the period from dry off
until parturition
More correctly identified as these 4
separate physiological states the cow
undergoes:
– Late Lactation
– Dry period
– Parturition
– Early Lactation
5.
6. Dry cow diets are often bulky and low in
nutrient density
» No production requirement
When cows freshen, they are introduced
immediately to a very dense (rich in energy)
ration
This will lead to many problems if not
handled properly
7. Group of diseases that mostly occur after parturition
i. Sub acute or acute acidosis
ii. Laminitis
iii. Ketosis
iv. Fatty liver
v. LDA
vi. Milk fever
vii. Downer cow
viii. Retained placenta
ix. Liver abscesses
x. Matritis
xi. Mastitis
xii. Bloat
xiii. Grass tetany
8. Important point is that all the metabolic
diseases are related to one another.
Animals affected from milk fever is more
prone to
Mastitis
Left Displacement of abomasam
Dystokia

11. Disease of high producing animals
Etiology:
– Onset of lactation (usually first 72 hr postpartum)
Normal:10mg/dL
MF: 5 mg/dL
– Affects older cows and Jersey breed more often
--Hypophosphatemia and hypomagnesiemia can
also be present
12.
13.
14.
15. Restoration of Ca ASAP
– --250-500 ml
– Can be administered s.c. in multiple sites
– Retreat 8-12 hr later, if needed
– Combination with ------------------in severe cases
• Cows with previous experience
– Ca gel orally 1 day before and I day after
calving
– Vit. D or 1,25 dihydroxy vit D, 8 days
before
calving, s.c.
16.
17. Withhold K+ fertilization from a filed that is in
its last year of production and use that crop for
dry cows ?!
---(full bloom) and use late cuttings -------is not a
bad option
Find low K+ hay source and combine with corn
silage (ration with < 2% K+)
18. ketosis and Fatty liver are most likely to occur during
periods when blood NEFA concentrations are elevated.
Incomplete oxidation of NEFA leads to formation of
ketones – aceto acetate and
beta-hydroxy butyrate
Mobilization of body reserves ensues
19. Etiology:
– Occurs during the ------------------------
postpartum
– Ketone bodies accumulate in the body fluid
– Affects high producing cows and cows that are
over conditioned during dry period
20.
21.
22. – 500 mL of 50% Dextrose solution (i.v.)
– Glucocorticoid injection (Dexametasone)
– Oral administration Propylene Gycol (PG)
7 days before calving
PG increase gulcose, reduces insulin>>
reduces fat mobilization
Feeding 3-12g of niacin per day may reduce blood ketones
Salts of propionic acid may be effective in lowering blood ketones
23. ------------------ must not be compromised
before and after caving
Be aggressive in treating other fresh-cow
diseases
(e.g. milk fever, retained placenta,etc.)
Adjusting the diet ----------by increasing
appropriate amount of concentrates in the
ration.
24. Refers to repositioning of abomasum from the right ventral
abdominal wall
– Twisting and displacement slows or stops flow
of digesta
– ---------- leads to bloat appearance
• “Pinging” detected with stethoscope by thumping the cow
near the last rib and listening on the left flank
– Displacements may be left or right sided (RDA,LDA)
Most are left sided
25. Symptoms
– Dramatically changes in the position of
abomasum
– Drastic decrease in milk
– Cows appear to be in pain/restless
Most often diagnosed within 14 days
postpartum
26. Non-surgical treatment
– Rolling cow over, taking on rough trailer ride
– Locating the abomasum, remove gas from
abomasum, toggle
– May only provide temporary relief
Surgical treatment
– Pull abomasum into place and attach it
surgically to body wall
27. • Prevention
Increasing the forage to concentrate ratio in diet
fed in late gestation and early lactation will
decrease the incidence
Grain intake after calving should be increased
slowly (0.25 kg/day)
Decline in the calcium around parturition
linearly decrease abomasal contractility, which is
suspected to lead to distension and abomasal
atony so supply ca in excess
28. Over-conditioning risk substantially
• Due to:
• High stress, Twins, etc.
• 12x as likely to retain placenta
• 4.9x as likely to have metritis
• Most often accompanied by the cascade
of fresh problems
29. • Rumen acidosis is associated with the feeding of diets with
higher grain amounts
It commonly occurs in the first month of lactation
Dry-off a cow is fed a high forage ration that is less energy
dense and higher in NDF than the lactation ration, it affects
rumen function
• Ruminal populations ill-suited to dense
rations after ~8 weeks on a dry cow diet
• Gram “-” toxins immune function
30. • Failure of fetal membranes to be expelled
from the uterus within 12 to 24 hours
– Dystocia and twinning increases incidence of
retained placenta
– More common in older cows
– Increased incidence with fat cow syndrome
and hypocalcemia, among other things
RP is indirectly associated with the higher occurence of
cystic ovaries
31. Extreme deficiency of dietary energy, protein or both can result in
RP.
Diets low in dietary crude protein (8%) for the entire dry period had
a higher incidence (50%) of RP compared with cows fed 15% crude
protein (20% incidence).
The rate of RP was associated with imbalances in Ca and P
metabolism
When the diet contained at least 0.12 mg/kg of Se and 1000 IU of
dietary vitamin E per cow/day, the incidence of RP is lower.
Avitaminosis of vitamin A
and β-Carotene was shown to increase the incidence of RP.
32. • Prevention
Proper nutrition specially during dry period
Supplementation with selenium
Adequate amounts of vitamin A and fiber
Proper body condition at calving
Over-conditioned cows are at an increased risk
Reduce dystocia– by proper managment
Assisted deliveries increase risk of RP’s
33. Characterized by excessive accumulation
of fluids in the intercellular tissue spaces of the
mammary gland.
Excessive intakes of sodium and potassium were
implicated as causative agents
Oxidative stress of mammary tissue resulting in
reactive oxygen metabolites may play a role in
udder edema
A diet must supply adequate vitamin E, copper,
magnesium, zinc, manganese and selenium.
34. It is most often associated with cows in early
lactation
grazing in pastures high in potassium and nitrogen
and low in magnesium and sodium
The disease will be more severe if accompanied by
hypocalcemia.
For prevention get an additional 10-15 g of Mg into
each pregnant cow and 30 g into each lactating cow
per day usually prevents further hypomagnesemic
tetany.
Magnesium is readily acceptable in grain
concentrates.
For 60 g of magnesium oxide just 0.5-1 kg of grain
will be effective.
35. The lactic acid, endotoxins and histamine
released as the rumen flora die, are
absorbed systemically and affect the
microvasculature of the growing hoof wall,
which then result in clinical laminitis
Avoiding an abrupt switch from dry-off ration
to high lactation ration will be a good start
for the prevention of laminitis.
