GENERAL OBJECTIVE
• To discuss the interrelationship of plants,
animals and man, and their roles in the
ecological system
• This will also help the students
appreciate the contributions of animals to
agricultural development and the economy
in general.
Specific Objectives
1. To discuss the relationship of man, animals and the
ecosystem
2. To give the economic benefits of animals to mankind
3. To determine the contributions of animals to
agricultural development and its relation to population
problem, and
4. To appreciate the development of animal science and
how it affects the animal industry
Terminologies
• Symbiosis – is a biological situation in which at
least two different kinds of organisms interact
• Animal Science – science that deals in managing
aspects related to production of domesticated
animals and animal products
• Domestic animals – animals which breeding is or
can be controlled by humans
Man
Ecosystem
Animal
Role of Livestock
• What are the specific roles (naibibigay) of
livestock?
Economic Contribution of Animals
• Philippine animal industry contributes billions of
pesos
• Main services: food, fiber, clothing, transportation,
tillage
• Support services: recreation (horses, fancy breeds),
and aide for differently abled (service dogs)
Economic Contribution of Animals
• Other uses: model for human experiments especially
in the medical field, production of pharmaceutical
products (vaccines), source of tissue or organ for
human ailments (xenotransplantation)
• Harvest of cowpox virus from calves in the late
1800’s
Pharmaceutical products from
transgenic animals
Challenges in Animal Production
• Animal Welfare issues
• Environmental impact of large-scale animal
production such as greenhouse gases, foul smell, and
pollution in bodies of water
• Alternative plant based food for meat and other
animal products
• Laboratory cultured meat
Tissue Cultured Beef
Animal Science Vs. Animal Husbandry
• Animal husbandry - how farm animals are bred and
cared for, typically by farmers
• Animal Science - study of animals and may help
develop new techniques in animal husbandry based
on research to increase growth and production, and
reduce disease and death rates
Factors Involved in Animal Management
1. Motivation of the persons involved
2. Level of knowledge and skills
3. Housing
4. Climate
5. Genetics
6. Health care
7. Product technology
8. General Management
Main Constraints in Improving
Animal Production
1. Ecological factors – land topography; soil fertility;
temperature; RH; plant growing season
2. Biological factors –genotype, animal diseases and
parasites;
3. Socio-economic factors – supply and demand
relationship; input-output ratio; prices; religion culture
and tradition; politics
