This document provides an overview of animal science. It defines animal science as the study and management of domestic farm animals, including their anatomy, physiology, care and production. It notes that animal science applies principles of biology, physics and social sciences to problems in animal production and management. Key areas of focus for animal science majors include animal production, breeding, care/management, health, and processing/marketing of animal products. The document also summarizes the economic contributions of major domesticated animal species.

Animal Science is best described as the study of the biology of animals that is
under human control
It is also described as the management and production of farm animals. It is
also called as Animal Husbandry
Animal Science deal mainly on the study of anatomy, physiology, care,
management and production of animals
Animal Science is concerned with the science and business of producing
domestic animals, including but not limited to cattle, buffalo, horses,
swine, sheep, goats and poultry

These will applies the different principles of the biological, physical
and social sciences to the problems associated with animal production
and management
If you want to be an animal science major, you will be inculcated
with in depth knowledge of the following:
1. animal production
2. Animal breeding and reproduction,
3. animal care and management
4. Animal health
5. Processing and marketing of animal products

ØWe must be aware that we are the caretakers and beneficiaries of
livestock and poultry production
ØAnd why animal science is important to the population?
Animals have many contributions to the human population, these
includes;
Food
Clothing
Livelihood
Work
Companionship

Food contribution of the animals alone, can directly
define the relationship between the human and animals.
Increase in human population means there is also an
increase in animal contribution.

Man, Animal and Ecosystem.
Man’s role in relation to plants and animals is beautifully defined
in Genesis 1:28-29 of the Holy Bible when God said to Adam and Eve:
“Be fertile and multiple, fill the earth and subdue it. Have
dominion over the fish of the sea, the birds of the air and over all the
living things that move on earth”. God also said, “See I give you every
seed- bearing plant all over the earth and every tree that has seed-
bearing fruit on it to be your food; and to all the animals of the land,
all the birds of the air and all the living creatures that crawl on the
ground, I give all the green plants for food”.

ØAn ecosystem is a community of living
organisms (plants, animals and microbes) in
conjunction with the non-living components
of the environment (things like air, water, and
mineral soil), interacting as a system.

10. ‘-

In an ecosystem the continued growth of plants and animals
depends on maintenance of the balance between the food
producers (plants) and the food consumers (animals and man).
Figure 1. Shows the components of an ecological system and
their interrelationships.

Animal and Their Economic Utility
Notwithstanding the relative inefficiency of animals in the production of food,
they are important components of the food production system. They have distinctive
attributes that enhance the ability of an agricultural system to produce food for
human:
1. Animals can feed on and convert plants and other materials which would
have otherwise gone to waste, into rich human food.
2. Animal products have chemical composition that closely resemble man’s
dietary requirements, and therefore more digestible and nutritious.
3. Used as draft, transport and amusement
4. Create other animal industries

13. ‘-

While food is the most important contribution of animals
to human welfare, animals have been domesticated by
man to provide him with the skin and hairs for clothing and
shelter, animal power for transport traction and beauty,
amusement and companion.
Table 1 gives the most important species of animals that
have been domesticated by for their economic value.

Animal Agriculture and the Population Problems
Even as the animals that are commonly raised for food are already
quite extensively produced, they are not enough to meet the world’s
protein needs.
With the ever-increasing human population and the attendant
contraction of load for agricultural production, the challenge to produce
more animal food products is becoming more and more severe. In recent
years, the rate of increase of Filipinos is already overtaking the growth in
livestock production in the Philippines.

Animal Science and the animal Industry
Through technological advances in animal science, the animal industry in
the Philippines has developed from a basically backyard and self-
subsistence production system.

The development of:
more efficient and productive breeds and varieties of
animals through breeding,
of cheaper and more nutritious feed materials for animal
feed,
of new drugs and feed additives,
of new systems of housing and management that more
economically improves the health and performance of animals,
of cheaper and more economical processing of animal
products, etc.
