Feeding Your Stud

Food and a clean environment are the two most important things that exhibition and/or breeding mice need.

I would recommend that mice are fed by scattering dry food on the floor rather than using a bowl. You can use a bowl if you'd like to, but you'll probably find that the mice scatter all of the food on the floor anyway and then use the bowl as a toilet. This makes unnecessary cleaning for you and between cleaning times the bowl becomes a haven for germs and will attract flies. Mice are not greedy eaters, so you should feed enough that they still have food left when feeding time rolls round again. It is better to discard food than let the mice go hungry as mice can lose condition very quickly. Due to their small body size and comparatively large surface area mice need to eat regularly to produce enough body heat and energy to do their daily activities, and will quickly become lethargic and ill if they go hungry. In addition, females with litters will cannibalise their young rather than go hungry. So never, ever let your stock run out of food.

You can use a multitude of feeds as your base. The base of the diet would need to consist of at least 70% grains (such as oats, barley, wheat, etc) or herbivore feed (such as rabbit or goat food). You can mix these to make the base; for example 40% rabbit feed, 20% oats and 10% barley, which adds a lot of variety for the mice to pick through. There is information on each of these options further down the page.

The remaining 30% can be made of bird seeds, dog kibble, cat kibble; basically any suitable dry food that is higher in protein than the grains. The ration of grains to protein foods can be varied to suit your mice. If your mice are looking greasy and itchy change the mix so it contains more grain. If you mice are lacking condition and their coats are looking drab, up the protein.


Making Your Own Mix from Straights

If you have a lot of mice, you'll find it cheaper to mix your own food than buy rat or mouse food. Large bags of straights (pure grain) for horses can be bought cheaply and easily at under £10 per 20kg bag, and you should mix these grains with bird seeds and/or dog food to complete the nutritional spectrum.

Here are some ingredients commonly used for mouse food:


Above Left: Rolled Oats. Above right: Flaked Barley


Above Left: Poultry Mixed Corn (contains wheat, barley and maize). Above right: Parakeet Seed Mix (contains wheat, millet, red dari, linseed, sunflower seeds).

Grains you can use in a mouse food mix include oats, barley, rye, wheat, maize, buckwheat and spelt. Some people add dried pasta and cereal to their mixes, but I personally wouldn't add processed food intended for humans to an animals' diet. If you do, make sure the foods you use are as low as possible in salt and sugar.

Mixing a Diet from Other Complete Livestock Foods

There are many other animals who share similar nutritional needs to mice, and their feeds contain many similar ingredients to rat/mouse food. These include pigs, horses, hens, rabbits and goats. Big bags of food can be bought fairly cheaply and are easily modified into a good mouse diet.

Goat Feeds:

FANCY FEED DRY GOAT MIX
Typical Analysis: Protein 14%, Oil 3,25%, Fibre 7.5%, Ash 7.5%
Ingredients: Bruised Oats, Micronised Barley, Hipro Soya, Micronised Maize, Wheatfeed, Micronised Peas, Linseed Lozenges, Locust Beans, Grassmeal, Soya Hulls, Beet Pulp, Oatfeed, Limestone, Dicalcium Phosphate, Vitamins and Minerals, Salt, Soya Oil, Sel-Plex, Molasses

SPILLERS GOAT MIX
Ingredients: 40-25% flaked barley, 25-10% grass nuts, wheat feed, flaked maize, sunflower ext, 10-0% molasses, flaked peas, rice bran, calcium carbonate, ammonium chloride, salt, hipro soya, oatfeed, vitamin/minerals, premix, dicalcium phosohate.

For mice, all that goat feed mixes are lacking is a meat based protein, so dog or cat food should be added.

Rabbit Feeds:

TITMUSS RABBIT MIX SUPREME (1)
Nutritional Analysis: Protein 12.5%, Oil 2.5%, Ash 4.3%, Fibre 6.6%, Vitamins A, D3, E and Copper
Ingredients: Flaked peas, grass pellets, whole oats, flaked maize, extruded biscuits, extruded locust beans, flaked wheat, whole wheat, herbs.

BURGESS SUPA FRUITI
Nutritional Analysis: Protein 13.5%, Oil 3.0%, Ash 4.0%, Fibre 7.0%, Vitamin A, D3, E and Copper
Ingredients: Flaked peas, oats, extruded biscuits, grass pellets, flaked maize, flaked wheat, whole wheat, carrot flakes, banana flakes, minerals and vitamins. Sprayed with an apple/peach flavour.

PETS AT HOME MUESLI RABBIT FOOD
Typical Analysis: Moisture 11%, Protein 13.5%, Oils and Fats 4%, Fibre 10%, Ash 4.5%
Ingredients: Wheat, Toasted Pea Flakes, Oats, Wheatfeed, Toasted Maize Flakes, Oatfeed, Grass, Sunflower Extract, Whole Maize, Apple (min. 4% in extruded nugget), Vegetable Oil, Lucerne, Vitamins and Minerals, Syrup, Carob Meal, Linseed. with Anitoxidant: EC Additive.

Again, a meat based protein is lacking, so dog or cat food should be added. Bear in mind that mice won't eat the grass/alfalfa pellets so there will be waste.

Horse Feeds:

BAILEY'S NO.10 RACEHORSE MIX
Nutritional Analysis: Protein 13%, Oil 8.5%, Ash 6.0%, Fibre 87.0%, Calcium 1%
Ingredients: Bruised Oats, Micronised Wheat, Molasses, Micronised Maize,Soya Bean Meal, Micronised Soya,Extracted Sunflower Meal, Micronised Peas, Soya Oil, Dicalcium Phosphate, Dicalium Sulphate, Distillers' Grains, Linseed, Vitamins and Minerals, Calcium Carbonate,Soya Hulls, Whey, Grass Meal, Calcined Magnesite, Sodium Chloride, Digest Plus prebiotic (ScFOS), Yea-Sacc1026.

JOLLYE'S HORSE AND PONY CUBES
Typical Analysis: Protein 8.5%, Oil 2.4%, Fibre 20%, Ash 9%
Ingredients: Wheatfeed, Chopped Cereal Straw, Oatfeed, Wheat, Cane Mollasses, Limestone, Full Fat Linseed, Salt, Minerals

MASHAM MICRONISED MIXED FLAKES
Analysis: Protein 12.5 Oil 2.9 Fibre 4.3 Ash 2.0
Ingredients: 50% Barley, 25% Peas, 25% Maize

Again, a meat based protein is lacking, so dog or cat food should be added.

Feed Suitable for Adding to Any of the Above:

Straight grains or any of the above feeds should make up 70 to 80% of the overall diet. The remaining 20 to 30% should consist of seeds and/or meat based proteins. Seeds which can be added to any of the goat, rabbit and horse feed listed above include sunflower, linseed, white millet, red dari, peanuts, pumpkin and black rape seeds. These can be changed for variety without upsetting the bulk of the diet. You can buy a variety of these seeds premixed in the form of parakeet mix, parrot mix and wild bird seed. Other feeds which can be added in addition to or instead of seeds include dry dog food and dry cat food. These don't have to be high quality. The expensive dog and cat feeds contain meat as their main ingredient whereas cheap ones have a lot more grain in them - which is not so good for cats and dogs, but better for mice.

Chicken feed (layers pellets and growers pellets) and pig feed (sow and weaner nuts) are also suitable for the base of a mouse diet. There'll be information coming soon about chicken and pig feed.


Dog Feeds:

There are a few dog feeds which are suitable for feeding as a complete mouse diet. Bear in mind that the cheaper the dog food the more grain it contains; so what would be a very cheap, poor diet for dogs makes an excellent mouse diet for breeding and growing mice. The two examples I've given below (Vitalin Original and Chudley's Original) contain 18% protein and the major ingredients are grains, which makes these suitable to feed on their own (for active breeding mice or growing weaners) or in a 50/50 mix with grains:

VITALIN ORIGINAL WORKING DOG MUESLI
Analysis: Protein 18%, Oil 3.2%, Ash 6.8%, Fibre 2.8%, Moisture 12%
Ingredients: Cooked Wheat, Cooked Sweetcorn, Meat & Marrowbone, Soya, Cooked Barley, Vitamins & Minerals.

CHUDLEY'S ORIGINAL WORKING DOG MUESLI
Analysis: Protein % 18.5, Oil % 8.5, Fibre % 3.0, Ash % 5.5
Ingredients: Wheat, chicken meat meal, maize, glucose syrup, chicken fat, wheat feed, peas, unmolassed beet pulp, chicken liver meal, dicalcium phosphate, soya oil, salmon oil, de-hulled soya bean, prairie meal, salt, yeast, potassium chloride, carrots, blackcurrant extract, charcoal, fructose oligosaccharides, with EC permitted antioxidants; mixed tocopherols, vitamin C and rosemary extract. With EC permitted colours, sunset yellow and ponceau 4R red.

Additional Foods

In addition to their staple diet, mice will enjoy a variety of treats. Hay is good for them, not only will they eat it, they will make nests from it and it'll keep their coat shiny as their bodies rub along the stalks. Millet sprays can be hung in the cage and provide an opportunity for climbing as well as eating. Dog biscuits are good for keeping their teeth ground down, and the charcoal dog biscuits will help keep their stomachs in good order. EMP (egg based canary rearing food), stale bread and milk mash, and Lactol (soluble puppy milk powder) are readily received and are excellent for helping growing animals grow to their maximum potential and providing pregnant/nursing does with plenty of extra nutrition. As a rarer treat, mice will enjoy things like cooked chicken (on the bone or off), fish, and dried or live mealworms. If feeding live mealworms, keep an eye out for any the mice haven't eaten, as they will borrow under the bedding and morph into big beetles. Linseed is good to feed for about a week before a show as it makes the mice' coats very shiny, but extended feeding will usually result in a greasy appearance. Mice will enjoy a variety of fresh or dry herbs, such as dandelion leaves and flowers.

The diet of nursing and growing mice can be supplemented with Lactol, eggfood, oat porridge, insects (mostly dried but occasionally live), dry cat food and bread and lactol or goats' milk mash.


Foods to Avoid

Mice don't need fresh green food and more than a very small amount will upset their stomachs, although cucumber can be provided for moisture when they do not have access to a water bottle - ie when travelling or at a show. Avoid any foods high in fat, salt or sugar like crisps, chocolate, cake and fruit, or any foods that are sticky or tacky.


Other Nutrition and Feeding Information:

All animals need five food groups. These are energy, protein, fats, vitamins and minerals. A good mix will have all of these in the correct percentages. Bad mixes have too much of one or two ingredients. An example of this is a mix made mostly of seeds and nuts. These mixes can cause skin complaints and kidney problems.

· Carbohydrates - these give energy for everyday life. They are found in grains, nuts, seeds and vegetables. Carbohydrates should make up about 75% of the daily intake. Lack of activity and loss of weight are symptoms of a deficiency.
· Proteins - These help the body tissues, such as muscles, blood, bone and nerves, to grow. They are found in meat, grains, seeds and nuts. Adult animals need less than 15% but growing and nursing mice need about 15% - 20%. Signs of deficiency are hair loss, fractures and failure to grow. Too much protein will cause major skin irritations and hair loss.
· Fats - Again, this builds body tissues or is converted into energy or fat stores. It is found in meats, nuts and seeds. Mice need very little fat, but deficiencies are recognised by a poor skin and coat.

Meat is important in a mouse's diet because it is valuable source of all the proteins.Fat is important in a mouse's diet, but too much puts extra weight on the organs and skeleton, thus shortening your pet’s life dramatically, just like with people. Vitamins and minerals are found in all grains, nuts and vegetables. Giving your mouse a balanced diet will ensure she receives all of them. A mineral block can help this, which is available in all good pet stores. It is an especially good idea to give a mineral block to pregnant and nursing mothers, for obvious reasons.

Commercial rat and mouse mixes will contain a protein level of 10 to 15%, which is perfectly fine for pets, but a mouse stud contains mice that need a lot more protein for breeding, nursing, growing, and keeping condition on the show bench. You want to be feeding 15% protein at the minimum but preferably it should make up 18 to 20% of the nutritional intake.


Below is a list of common ingredients in rat food and what they provide:

Wheat - provides several of the B vitamins, potassium, iron, magnesium and zinc
Wheatfeed - (wheat production by-products ie wheatgerm, husks etc)
Bakery by-product - (recycling of inedible bakery waste such as bread, dough, pasta)
Oats - provides several of the B vitamins, calcium, magnesium, iron, zinc and small amounts of vitamin E, folic acid and potassium, helps with glucose and insulin modulation.
Barley - copper, phosphorus and zinc, soluble fibres that lower high blood cholesterol
Flax Seed - omega 3 oils (essential fatty acids)
Sunflower ext - polyunsaturated fat to help lower cholesterol
Rape Seed ext - rape seed product for protein
Low Glucorape - rape seed product for protein
Palm Kernel ext - polyunsaturated fat to help lower cholesterol
Molasses - magnesium, potassium, vitamin B6, sugar
Soya Bean/Soybean - Manganese, Vitamin C, Folate, Dietary Fibre, Protein, Thiamin, Calcium, Iron, Magnesium, Phosphorus, Potassium.
Calcium Carbonate - provides calcium
Salt - electrolyte in the body and is required in the manufacture of hydrochloric acid in the stomach, which protects the body from any infections that may be present in food.
Lysine - growth and bone development, assists in calcium absorption, maintaining the correct nitrogen balance and maintaining lean body mass. Furthermore it is needed to produce antibodies, hormones, enzymes, collagen formation as well as repair of tissue.
Fish Meal - (Made from fish and fish preparation by-products considered unfit for human consumption) provides protein and oils
Meat Meal - (Made from meat and meat preparation by-products considered unfit for human consumption) provides protein and fats.
