The History

Hormoform was first launched in 1954, after 2 years feeding trials,
involving some of the leading fanciers. Hormoform is a supplementary
feed, which was probably the first truly scientifically, formulated
supplementary feed ever offered to the racing pigeon.

The results were remarkable. Fertility and virility improved and
Hormoform's influence on the production of crop milk ensured strong
well-grown youngsters.

Birds raced better than ever and, as a result, demand for Hormoform has
increased steadily since it's introduction. This and the fact that most of
the important races have now been won by Hormoform prepared birds,
demonstrates the satisfaction and confidence fanciers have found in this

The Formulation

Hormoform is a compound of energy-yielding fats and oils, animal and
vegetable protein, yeast, cod-liver oil, malt extract, amino acids,
vitamins, minerals and trace elements supported on a cut-wheat base.

The calculated typical analysis is as follows:

12% Protein
8.8% oil
5.1% Fibre

The protein in Hormoform is designed to complement the protein in the
traditional diet not replace it.

The nutrients contained in Hormoform include:

Vitamin A Nicotinic Acid
Vitamin D3 Calcium Pantothenate
Vitamin K Biotin
Vitamin D1 (Thiamine) Inositol
Vitamin B2 (Riboflavine) Choline
Vitamin B6 (Pyridoxine) Amino Benzoic Acid
Vitamin B12 Lysine
Chloride Cystine Glycine
Iodine Calcium
Cobalt Sodium Chloride
Copper Phosphorus
Manganese Zinc
Iron Arginine
Methionine Tryptophane

The Principle behind Hormoform

Hormoform is formulated to supplement the traditional mixture,
meaning, for example that if a vitamin is recognised as being at
a low level in the traditional mix, it will be included at a high
level in Hormoform.

Over the years, the formulation of Hormoform has been adjusted
to take advantage of the most recent research. These small but
significant changes enable the fancier who used Hormoform to benefit
from the latest developments in nutritional science, at the same
time relying on a feeding system that has stood the test of time.

Most Recent Change

Most recently, the role of methionine in relation to feather
quality has been identified. Feathers are made up of a protein
called Keratin. This protein contains a large percentage of
sulphur, an element that is mainly absorbed from the diet in the
form of methionine (free sulphur cannot be absorbed and passes
straight through the bird).
Methionine is an amino acid (from which proteins are made) and
the bird is totally reliant on it's presence in the feed.

Because of the importance of feather quality and the fact that
traditional feed mixtures many be low in methionine, the most
recent improvement to Hormoform has been to increase the level
of methionine included in the mix. This means that birds fed
Hormoform are unlikely to be deficient in methionine so feather
quality will be optimised.

Feeding Instructions

Resting Birds - 57g (2oz) per 450g (1lb) feed
Racing Birds - 71g (2.5oz) per 450g (1lb) feed
Breeding Birds - 86g (3oz) per 450g (1lb) feed

Hormoform should be given daily with the feed at the recommended

Hormoform can also be given separately, in a container, for the
birds to feed to their own individual requirement.
