Kusuri Growth Food 1.5kg 6mm Med Pellet

Following on from years of research, we at Kusuri have developed new Kusuri Growth food.

Kusuri Growth food contains the highest quality proteins to promote rapid growth, without the risk of any build up of fat deposits inside the body of the fish.

As with all of the Kusuri food range, the primary consideration was to produce a natural dietary pellet for Koi. We have developed a precise blend of lipids and other vital nutritional ingredients to promote both rapid growth and good body shape.

For best results, this high protein food should be fed when the water temperature is above 20°C. Small volumes of food throughout the day is the preferred method of promoting the potential for maximum growth, whilst maintaining water quality.

When feeding larger Koi (3 years and older), Kusuri Growth food can be mixed with FPF 1, Multiseason or Supersilk- 20 for best results.

This food is superb! The most versatile of our foods, rapidly gaining a deserved reputation for amazingly low waste production.

We have formulated Multiseason specifically for Northern Hemisphere temperatures so it can be fed conveniently as a pellet food, without any residue on pond water.

Containing Kusuri Klay, Propolis, 'Optimum' health enhancer and pre-biotics, Multiseason is a very special recipe acknowledged as having the ultimate ingredients for feeding to produce excellent growth and colour improvements in koi. You will discover that feeding little and often will produce very low levels of fish waste. Multiseason can be mixed with any of the other foods in the Kusuri range.

Kusuri Wheatgerm Food 1.5kg Med Pellet

Kusuri Wheatgerm has been especially formulated, now with increased garlic and wheatflour free, to aid digestibility.

This wheatgerm formula contains the high nutrient ingredients included in the FPF-1 formula, such as krill, kelp, garlic, propolis and optimum. Wheatgerm feeds can of course be fed at any time, but are particularly popular during autumn, winter and early spring periods when pond water temperatures are low and a reduced feeding protocol is usually adopted. With this in mind, Kusuri Wheatgerm has been deliberately developed to include a very high level of vitamins, minerals and other direct medicinal inclusions. One of these is called 'Optimum'- a proven natural additive that stimulates resistance to disease infection, and helps promote tissue cell growth.

Kusuri Super Growth Paste Food 1kg

Very high growth, superb colour, and very low waste. The ultimate fresh food for Koi!

Kusuri Growth paste food comes as a powder, and when mixed with water makes a dough consistency to be fed directly to your koi. Because this food has not been processed by heating and cooking, none of the valuable nutrients are lost. The maximum recommended life of the mixed product (dough) is 3 days provided it is refrigerated.

Super Growth is a high protein (63.4%) special formulation paste food, and when fed to your Koi in conjunction with good water conditions will produce superb growth. The high protein level of this food when digested by Koi, is reduced down into constituent amino acids that will produce better muscular growth and provide further energy. This high protein food is beneficial when fed to Koi at temperatures above 68°F (20°C).

Super Growth paste food will also show marked reduction in fish waste material, aiding water parameters. The high quality white fish meal in this product will also improve the base white pigmentation of the Koi. Our high protein paste food has been formulated to provide highly effective growth potential through the summer months, and should only be used at this time of year, or in a temperature controlled system.

Premium Medium/Large Pellet

Premium (formerly known as FPF-1)

The most popular food so far in the Kusuri range.

A very high quality, highly medicinal, immune enhancing, floating food for Koi.

There is a wide choice of Koi foods these days, so what makes you decide on one over another. Price? Reported analysis? Ingredients? How fresh the food is? Where it comes from maybe? The bottom line on deciding on a pellet food is probably trying to achieve a balanced combination of all these arguments. We hope our Premium pellets can give you food for thought.

Kusuri Premium again fills a requirement we feel, for a very high quality Koi food manufactured on a fresh regular basis in the UK. A food sensibly priced which has just about everything beneficial included in a cyprinid diet, a spectrum of beneficial ingredients unsurpassed by any other food made anywhere in the world. Made exclusively to our own researched formulation, we do not use any chemical colour enhancers or substitute proteins.

Koi have quite strict requirements for lipids, fibre, minerals, vitamins and protein. Some ingredients will supply essential lipids, fibre, minerals, vitamins and amino acids, but alone, lack the required levels that are needed for Koi.

In fact, the presence of certain excess Amino acids can have detrimental effects on the rate of growth. For example, high levels of Isoleucine are known to reduce the growth rate on carp. We have formulated our food to provide the correct balance of all the major requirements for Koi. Additionally Kusuri foods are the only ones available with Kusuri Klay included - research proven for better growth, colour, and aiding the prevention of stress protein production.

Included are the immune enhancing properties of propolis, garlic and brewers yeast. Kusuri Premium is formulated for low waste and low nitrogenous output, as well as high growth, with natural chemical free colour enhancement. Also included is a generous amount of wheatgerm, along with the improved nutrient assimilation properties of Kusuri Klay. We advise no minimum feeding temperature, although we do thoroughly recommend that feeding is dramatically reduced below 10°C (50°F).

Major ingredients include:

Fish meal, Shrimp meal, Antarctic Krill meal, Crab meal, Soya bean meal, Wheatgerm, Kelp, Propolis, Spirulina, Kusuri Klay, Garlic, Brewers yeast, Fish oil, Vitamin A, Vitamin D, Stabilised Vitamin C, Vitamin E, Dicalcium Phosphate, Choline Chloride, Niacin, Riboflavin (Vit B2), Pyridoxine (Vit B6), Thiamine (Vit B1), Calcium Pantothenate, Biotin (Vit H), Folic Acid, Cobalamin (Vit B12), Inositol, Minerals (Magnesium, Zinc, Selenium, Manganese, Copper, Iron).

Basic analysis: Protein 37%, Oil 6%, Fibre 3.2%, Ash 9.7%, Moisture 10%.
