ANSOO3 Flashcards
the science of heredity and the variation of
inherited characteristics.
Genetics
the use of biometry and genetics to improve farm animal production.
Animal breeding
the study of nutrients and how the body uses them.
Animal Nutrition-
the study of the physical and chemical processes of an animal or any of the animal’s body systems or cells.
Animal Physiology
is the study of how diseases, parasites, and environmental factors affect productivity and animal welfare
Animal Health
the science of handling, distributing, and marketing meat and meat products.
Meat science
the science of providing milk and milk products as food.
Dairy product science
a collective set of tools and applications of living organisms, or parts of organisms, to make or modify products, improve plants or animals, or develop microorganisms for specific uses.
Biotechnology
it is the study of the entire meat
industry from animal production to
the preparation and marketing of
the final product.
Meat Science
Meat originates from the old English word ____,
which referred to food in general.
mete
Constraints
- Prolong droughts in some parts of the world
- The spread of the African Swine Fever (ASF) and
associated import restrictions - The spread of the highly pathogenic avian influenza (HPAI)
- Global antimicrobial standards
- Animal welfare compliance
- Strict environmental regulations
- Higher tariffs on imported soybean and increased maize prices
Prospects
- Abundant global export supplies and market demand
- Continuing increase of urbanized population with higher incomes and changing food habits
- Improvements to grandparent stocks
- Increase support from the government for expansion
Connective tissue that surrounds the muscle as a whole
epimysium
Connective tissue which surrounds bundles of muscle fibers
perimysium
connective tissue which surrounds each muscle fiber
endomysium
is the process from which the embryo is formed and develops into a fetus.
Embryogenesis
is the development of muscle tissue during the embryonic stage.
Myogenesis
Stages of early development
A. Fertilization
B. Cleavage
C. Gastrulation
D. Organogenesis
is the process of a single sperm cell combined with a single egg cell to form a zygote.
Fertilization
is rapid, multiple rounds of mitotic cell division where the overall size of the embryo does not increase. After the completion of cleavage, the developing embryos (blastula) is
formed.
Cleavage
the rearrangement of cells in the blastula creates the embryonic tissue layers that will lead to tissues and organs formation
Gastrulation
the process of tissue and organ formation via cell division and differentiation.
Organogenesis
Causes of glycogen depletion which resulted to DFD meat
- Long transport-hauling of animals,
- without feeding, and
- exhaust muscle glycogen.
