1L, 5L. Dark, sweet flavoured syrup

Withholding period: Ranvet FerroMax does not contravene the rules of racing in any jurisdiction and has no withholding period

Actions: FerroMax with Folic acid is a palatable, sweet, oral iron supplement for use where dietary iron levels may be low, and where there are relative deficiencies during early growth stages in young dogs. With bitch’s milk being low in iron, and most cereal grain based diets low in folic acid, FerroMax is a beneficial feed supplement for pups, pregnant and lactating bitches, as well as for training and hard working greyhounds.

Technical Issues: Ranvet FerroMax with Folic Acid

A good blood count is critical for racing performance in greyhounds: designed for maximum exertion over short distances. Anything less than an optimum blood count will result in reduced performance, because red blood cells are responsible for the transport of oxygen to hard working muscles. A decrease in the number of red blood cells, or in their ability to transport oxygen in any way means that less oxygen is available to fuel exercise.

The average greyhound has about 3 litres of blood that circulates through the body approximately every 30 seconds. This volume actually represents about 10% of total body weight. The body can survive the loss of many components, but it cannot survive without blood. If 50% of the blood is lost, the greyhound will die within minutes. Even the rapid loss of 1 litre (30%) can often be fatal without an immediate blood transfusion.

Anaemia
A deficiency of red blood cells or of the haemoglobin inside the red blood cells is called anaemia. The different types of anaemia in greyhounds are named according to whether there is a change in the total number of red blood cells, or a reduction of the haemoglobin in each red cell, or a combination of both. The normal number of red blood cells for a racing greyhound is between 9 and 10 million per cubic millimetre (about 1 drop) of blood

There are multiple causes of anaemia, including;
a) Infestation with blood sucking worms (hookworms and whipworms). The average worm will take about 2mLs of blood in 24 hours
b) Lack of iron in diet
c) Lack of B group vitamins
d) Bleeding from any injury, even torn muscles
e) Reduced manufacture of red blood cells or haemoglobin (known as “sport anaemia”)

Haemoglobin
The production of haemoglobin (the red coloured pigment in blood responsible for carrying oxygen) is complex, requiring protein, B group vitamins B2, B6, B12, Folic acid, vitamin C, plus the minerals cobalt and copper, in addition to iron. No amount of iron alone will increase haemoglobin levels in red blood cells. A combination of all the critical cofactors mentioned here is required in very precise steps. FerroMax does not include any of these apart from Folic acid, which is often the limiting vitamin for the formation of healthy red cells, as other minerals and vitamins are usually readily available from the diet and other supplements such as  VitaMax.

Iron is an essential component of the oxygen carrying haemoglobin in red blood cells, as well as myoglobin in muscle tissue, and many enzymes involved in normal respiration.

The physiological importance of iron is vital to all tissues and organ function. In the normal dog the excretion of iron is very closely regulated to conserve body reserves. More than 75% of body iron is functional, with the remainder in storage in tissues such as liver, spleen, kidneys, bone marrow.

Normally, every 100mL of blood will contain 18-20gms of the protein haemoglobin in greyhounds. Levels of haemoglobin below 18gm/100mL of blood mean reduced oxygen transport with reduced stamina and endurance. Quite often early speed up to about 270 meters is unaffected by a low haemoglobin level, but it is only when fatigue begins in the latter part of the race that the low haemoglobin level will be reflected by poor performance. How many dogs have you seen “hit the wall” close to the end of a race? Greyhounds with low haemoglobin levels will not only tire more easily, they will take significantly longer to recover.

Packed Cell Volume (PCV)

A fit, trained greyhound will normally have a PCV (Packed Cell Volume) of 60-65%. This is much higher than for normal dogs. As greyhounds progress through training to full race fitness, the red blood cell count and PCV increase in response to the need to transport more oxygen with increased activity.

Anaemia due to iron deficiency may be caused by the constant stress of training and competition, worm infestations, insufficient training, or actual blood loss.

Levels of red blood cells lower than 58% in the PCV (Packed Cell Volume) suggest varying degrees of anaemia, with associated poor performance, early fatigue, and slow recovery from runs.
When the PCV falls to about 50% the dog looks very dull, with a picky appetite, loss of interest in work, and generally being “off colour”, but not obviously ill. The coat will be dry and coarse, and the skin will lack tone and elasticity.

On the other hand, a PCV which is too high can be equally serious in reducing performance. When a resting dog’s PCV is over 65% it means there are too many red cells in the blood, which becomes too thick to pump around the body. The heart simply cannot pump the thick blood quickly enough, and performance again reduces due to lack of sufficient oxygen. If the PCV rises to around 80%, the greyhound is likely to die, and this sometimes occurs when dogs are back in the catching pen after races if the PCV is too high.

Red blood cells normally last for about 80-120 days in the circulation, and they are then broken down, recycled, and replaced by new red cells which are manufactured in the bone marrow. Hard training and exercise can see the life of red blood cells reduced by about 50-60%. In many cases of training stress the ability of bone marrow to produce sufficient new red blood cells may be significantly reduced, resulting in anaemia, loss of performance, and “training off”.

In addition to training stress, heavy parasite burdens, poor or imbalanced nutrition, or illness and injury may result in excessive loss of red blood cells. White meat diets are usually low in iron, copper and vitamin B12, and cereal based diets (kibbles) may often be deficient in folic acid. If dogs are not trained or slipped to provide maximum exertion regularly then there is not enough stimulus to manufacture sufficient new red blood cells to cater for maximum exertion.

Heavy Hookworm or whipworm burdens, and even fleas, can remove significant amounts of blood on a daily basis. Make sure all dogs are properly treated with anthelmintics (worm treatments) on a regular basis.

The Importance of Red Blood Cell Counts

A low red blood cell count or a low haemoglobin level is a common finding in racing greyhounds.

Red blood cells are the most plentiful cells in the body. Produced by bone marrow, they take about 120 days to actually manufacture, and last in the blood for roughly 150 days.

The primary function of red blood cells is to carry oxygen around the body, locked into the haemoglobin within the cells. Haemoglobin is a protein that binds oxygen when it is breathed into the lungs, then transports the oxygen to the tissues such as muscle, as it is required. On the return trip, haemoglobin collects the carbon dioxide produced during muscle and tissue activity, and transports it back to the lungs for elimination from the body. Haemoglobin contains iron as an integral component. Without iron, haemoglobin cannot function.

A low red blood cell count will have a lower capacity to transport oxygen around the body, so a dog with a low red blood cell count will have a lower ability to perform because of decreased available oxygen to hard working muscles and other tissues, and a decreased elimination of toxic wastes such as carbon dioxide. (If carbon dioxide levels increase in working muscles, for example, this increases the acidity of muscle fluids. You know this as acidosis)

While it is rare for a fit greyhound to be clinically anaemic, many have lower than normal red blood cell counts, low haemoglobin levels, or other blood cell abnormalities. Vets diagnose anaemia firstly on a PCV (Packed Cell Volume), which is an indication of the amount of red cells compared to the amount of fluid in the blood. The PCV actually varies a little depending on age, breed, and level of fitness.

You will have seen many blood tests conducted on greyhounds, and it is important to understand that normal ranges for blood parameters actually vary between laboratories because of the techniques they use for each test, and also because some labs have normal ranges for dogs in work, where other labs have wider ranges for general dog types. Try not to compare one lab result with one from a different lab without advice from your vet.

How Can Low Red Cell Counts Develop?
There are many causes, but primarily;
a) blood loss
b) inadequate iron or other essential cofactors (folic acid, vitamin B12, etc)
c) insufficient training and conditioning to stimulate red cell production

Blood Loss:

Internal or external parasites (worms, fleas) can result in significant blood loss. It is important to supplement young greyhounds first coming into preparation with iron, as well as to treat them comprehensively for worms and other parasites to minimise blood loss.
Haemorrhage (bleeding) from injury or surgery can be common.

Deficiencies of Essential Minerals, Vitamins

As well as iron, the body absolutely requires the minerals cobalt, zinc and copper, as well as vitamins B6, B12 and folic acid, all in combination, to produce adequate red blood cells. If each of these essential nutrients is not available at the time it is required, no red cell formation occurs. A deficiency of one nutrient can totally stop all red cell manufacture until that nutrient is available. Many trainers are only aware that iron is required for red cell formation, but a deficiency of any of the above nutrients will cease red cell production regardless of how much iron is available.

Inadequate Training or Conditioning

A greyhound needs to work at top speed to fully stimulate bone marrow to produce adequate red blood cells for the type of work it will be doing.

It is important to remember that during all exercise and training, there is damage to red blood cells, just as there is damage to muscle and other tissues from free radicals produced as dogs exercise. The red cells need to be repaired and replaced during recovery periods, just as muscle tissue needs to repair. For this to occur, adequate raw materials need to be available at all times, or trainers begin to see dogs ‘training off’ as the stress of training and racing leads to reduced ability to recover and repair the body.

Why Supplement Greyhounds?

Greyhounds in full work can have significantly higher requirements for all nutrients than resting dogs. These nutrients are not always adequately available from the diet at all times, depending largely on the type of diet fed. Haematinic supplements such as FerroMax provide the critical components in sufficient levels to augment the normal diet and ensure that there are no deficiencies.

Similarly, pregnant and lactating bitches, young growing pups, and those dogs with heavy parasite burdens or illness and injury, require help from supplements to adequately restore red blood cell levels.

Pregnant and lactating bitches need supplemental iron to prevent iron deficiency anaemia in young pups brought on by reduced iron reserves in the mother’s body, as well as anaemia from hookworm and similar parasite infestations. Newborn pups have a rapidly expanding blood volume, and bitch’s milk is a poor source of iron generally. Supplementation of the lactating bitch, as well as ensuring quick access to good quality feed or supplementation for growing pups is critical to optimum development

Supplements vary in availability, risk and function

Injectable iron supplements have long been used for dogs. The iron reaches tissues and blood rapidly, but there is considerable risk of allergic reaction to the injected supplement, as well as the risk of overdosing on iron, and the risk of injection site pain, irritation and infection.

Oral iron supplements (either powder or liquid) are absorbed from the gut, and any iron or other cofactor which is not immediately required is passed out in faeces, significantly reducing the risk of overdosing iron

Remember that iron supplements added to a meal may act to reduce the availability of any vitamins included in that ration. Try to add iron supplements separately in, say, the evening feed, while all vitamins and other supplements are added to the morning feed, to ensure maximum availability of all nutrients.

The important issue for owners is the question: Which type of iron is best?

The older inorganic iron salts such as iron oxide, ferrous sulfate, ferrous phosphate are very poorly absorbed, and are now rarely used in modern iron supplements. They can easily overdose iron, and can irritate the gut, as well as reduce the availability of many vitamins and cofactors in the same diet.

The more modern organic iron supplements such as chelates, iron ammonium citrate, ferrous gluconate and iron carbonyl, are very well absorbed from the gut, and provide a much greater margin of safety, with little risk of iron overdosing. FerroMax uses organic ferric ammonium citrate.

FerroMax is safe to use. The iron provided in oral supplements is less than the RDA (recommended daily intake) for dogs, because other foodstuffs also contain iron in variable amounts. High cereal grain based diets and white meat diets (chicken) are usually quite low in iron.
The maximum tolerable level of iron is approximately 40-50 times that provided by normal oral iron supplements in use today. In addition, the organic nature of the iron in FerroMax provides additional safety and bioavailability.

Why Does FerroMax with Folic Acid not have the minerals cobalt, copper and zinc as well?

This is deliberate. Although these minerals are essential to good red blood cell formation, they are almost always available from a wide range of other supplements regularly fed to dogs, including in complete feeds and kibbles. These essential nutrients are available in Ranvet VitaMax, for example, so there is little requirement to add them into FerroMax as well. This only makes products unnecessarily expensive, with little additional benefit. FerroMax contains Folic Acid because this is most commonly the limiting vitamin in the process of creating adequate red blood cells.

What’s The Best Way to Prevent Sport Anaemia in Greyhounds in Work?

The best way is to combine nutritional supplements, feeding and training schedule, depending on the need and stage of fitness;

a) Make sure the dog has sufficient exercise, conditioning and training to strengthen and condition bones, tendons and ligaments, as well as sufficient maximum exertion work to fully stimulate the maximum production of red blood cells and haemoglobin
b) Use daily haematinic supplements such as FerroMax and VitaMax to provide all of the essential nutrients (vitamins, minerals and trace elements) required to build blood counts, muscle and bone tissue, and to ensure rapid recovery after work.
c) Use additional supplements such as Foliphos at times of excess stress to make sure blood counts remain at optimum levels.
d) Make sure you keep dogs flea-free and wormed with Ranvet WORMFREE ALLWORMER to prevent excess blood loss and reduced performance
e) Start young pups on worm treatment and FerroMax plus VitaMax as soon as training starts

COMBINING ELECTROLYTE SUPPLEMENTS FOR MAXIMUM PERFORMANCE

It is widely accepted as essential to supplement electrolytes daily in the diet of performance greyhounds, and the rate of supplementation will vary with the degree of fitness, work levels required, and the environmental conditions.

Electrolyte losses can be significant even in cooler months, and it is recommended that daily supplementation continue during all training and competition stages.

Ranvet Recommendations:

Use Ranvet Salka-Lite daily in feed or water to supplement the essential electrolytes and B group vitamins at a dose rate of 4g twice daily in morning & evening meals. Use in drinking water when travelling, if required.

For dogs which tend to develop acidosis, with muscle fatigue, cramping and poor performance, supplement with Ranvet NeutraMax in combination with Salka-Lite to reduce acidosis, pain and cramping in muscles and improve recovery.

Help hard working dogs, and those with poor appetite by supplementing Ranvet K-Max in addition to Salka-Lite daily electrolyte

Is The Dog Off It’s Feed? Ranvet Foliphos gives a quick lift and stimulates appetite.

Ranvet K-Max is vital to supplement potassium in dogs that are off their feed, especially nervous, excitable dogs, heavy panters and barkers, and those tending to cramping &muscle fatigue.

Need Fast Muscle Recovery After Hard Work?

Ranvet NeutraMax given after hard work reduces acidosis in muscle and blood to hasten recovery

Ranvet Muscle-G provides the complete package of nutrients involved in muscle function. To prevent muscle damage and the associated signs of stiffness, soreness, fatigue, cramping and lack of stamina
