Basic Nutrition
Despite what many supplement manufacturers may wish for you to believe, basic
nutrition is science-based, not magic. Years of research have provided details to
the once unknown intricacies of animal nutrition. Nevertheless, optimal nutrition
will not cause your animals to perform at a level, which surpasses their genetic
potential. However, poor or inadequate nutrition will play the largest role in hindering
the abilities of a high performance animal. Much like human athletes, the nutrition
of high-performance animals is confounded by many factors. Stress incurred through
shipping, racing, and co-mingling results in a dynamic cascade of special nutritional
needs.
Four forces impact the performance of all animals:
1. Nutrition Program
2. Health Program
3. Breeding Program
4. Management Program
The magnitude to which each of these factors play their ultimate role will vary
depending on the producer. Nevertheless, nutritional programs are and will continue
to be one of the most influential and yet dynamic components of any successful animal-rearing
program.
Overview of Basic Nutrition
There are six basic nutrients required by all animals:
1. Water
2. Carbohydrate
3. Protein
4. Lipid
5. Minerals
6. Vitamins
1. Water
I have listed water as the first essential nutrient. This may surprise many of
you; however, water is the MOST important component in the whole nutritional framework.
It is absolutely essential that animals have access to a daily supply of clean, fresh
water. We strongly advise that every loft have the quality of their water supply
tested annually. Hey, in most cases you and your family are drinking it too; it's
a Win / Win.
Water is important for many bodily functions including:
A. Transport of nutrients B. Chemical reactions C. Regulation of body temperature
2. Carbohydrates
The main function of carbohydrates is to provide energy for the daily life processes.
This nutrient is found in the starchy components of grains and is measured by a caloric
(calorie) value. The term carbohydrate describes a large group of sugar-based compounds,
which are ultimately composed of glucose-unit building blocks.
Most nutritionists will refer to feed quality as total and digestible energy.
For instance, plant tissue is an excellent source of energy through carbohydrates;
however, this energy form is a poor source of digestible energy for birds and pigs.
Grains, on the other hand, are more suitable sources of carbohydrate nutrition for
these animals.
3. Protein
Protein is composed of several singles, repeating units called amino acids. When
amino acids are linked together in a specific sequence they form proteins. Protein
is an integral nutrient for tissue growth and repair, as well as, support for important
physiological functions such as reproduction and immunity. Sources of protein for
pigeon feeds include soybean meal, peanuts, and peas. In many cases, high protein
grains also contribute to the energy value of a diet. Protein levels supplemented
beyond the animal's requirement will be utilized as energy.
As nutritional sciences become more advanced we have become able to supplement
synthetic amino acids to animal diets. This is best illustrated by the common use
of synthetic lysine and methionine in manufactured diets. When evaluating the protein
quality of a feedstuff it is more important to consider the ratio and content of
essential amino acids versus the protein concentration alone.
4. Lipids
Fats and oils are the most common sources of lipids in animal diets. This nutrient
is characterized by its dense energy value. Subsequently, fats are supplemented to
diets I increase the energy concentration without increasing overall diet bulk. Lipids
are also essential for the efficient absorption of fat-soluble vitamins, as well
as, the production of all natural steroids.
5. and 6. Vitamins and Minerals
This area of nutrition is often considered the micronutrient section. In some
cases, little is understood about the true micronutrient needs of animals; let alone
high-performance animals. Consequently, vitamin and mineral nutrition is often viewed
as a key component, which can make large differences in an animal's overall performance.
Vitamin nutrition is divided into two categories, fat-soluble and water-soluble.
Fat-soluble vitamins can be stored within the body and called upon when needed to
fuel metabolic functions. Water-soluble vitamins are not readily stored and must
be consumed on a regular basis to avoid deficiency complications.
Common Fat Soluble Vitamins
Vitamins A, D, E, and K Common Water Soluble Vitamins: Vitamins B and C
Mineral nutrition is also divided into two categories, macro-minerals and trace
minerals. Distinction between these categories is primarily made by the concentration
required in the daily diet. While macro-minerals are often required in amounts exceeding
.5% of the total diet, trace minerals are often required in amounts less than .001%.
Careful attention to mineral nutrition is essential to optimize all physiological
functions, such as: reproduction, growth, immunity, and endurance.
Common Macro-Minerals
Calcium Phosphorus Potassium Magnesium Sodium
Common Trace Minerals
Copper Zinc Selenium Manganese Chromium
Many minerals, especially trace minerals, may become toxic when supplemented at
levels beyond requirement. Further, the excessive supplementation of one mineral
may result in a forced deficiency of another. It is important to supplement only
those minerals recognized as essential for avian diets. Therefore, caution should
be taken when attempting to use a mineral supplement which was not specifically formulated
for that specie of animal which your are feeding it to.
Summary
This has been a general review of basic nutrition and the six essential nutrients
involved. Quality nutritional programs are characterized by their ability to provide
a consistent supply of essential nutrients in an easy to manage affordable diet.
Care should always be taken to the development of dietary programs, which offer a
consistent delivery of balanced nutrition. No single program is suitable for every
situation. Available feedstuffs, animal type, production stage, and performance expectations
will all play vital roles in the development of these programs.
